Plants are the primary producers in most ecosystems, providing food and shelter for other organisms. Plants have a long evolutionary history, and there are millions of species of plants in the world today. In this article, we will discuss the classification of the plant kingdom, the structure and function of plants, and the importance of plants in our ecosystems.  Classification of the Plant Kingdom The plant kingdom is divided into two major groups: vascular plants and nonvascular plants. Vascular plants are those that have a vascular system that transports water and nutrients throughout the plant body. Examples of vascular plants include trees, ferns, and grasses. Nonvascular plants, on the other hand, lack a vascular system and must rely on other methods for transporting water and nutrients. Examples of nonvascular plants include mosses and ...

Chemical control and coordination Mind map NEET Class 11 Best for revision short notes FREE mind map PDF is given at end of this page There are special chemicals which act as hormones and provide chemical coordination, integration and regulation in the human body. These hormones regulate metabolism, growth and development of our organs, the endocrine glands or certain cells. The pituitary gland is divided into three major parts, which are called as pars distalis, pars intermedia and pars nervosa. Pars distalis produces six trophic hormones. Pars intermedia secretes only one hormone, while pars nervosa (neurohypophysis) secretes two hormones.  The endocrine system is composed of hypothalamus, pituitary and pineal, thyroid, adrenal, pancreas, parathyroid, thymus and gonads (testis and ovary).  In addition to these, some other organs, e.g., gastrointestinal tract, kidney, heart etc., also produce hormones.   The pituitary hormones regulate the growth and development of ...

Neurons, the functional units of neural system are excitable cells due to a differential concentration gradient of ions across the membrane. The human Central Nervous System (CNS) is a network of over 100 billion individual nerve cells that regulate our actions, sense our environment and process our thoughts. The CNS includes the brain and the spinal cord, which together coordinate and control the movement and activities of the body. The Central Nervous System is responsible for sensory input, integration, control of muscle and glands, homeostasis, and mental activities. Sensory input is detected by the nervous system through sensory receptors that detect external and internal stimuli. These stimuli range from vision, hearing, smell, touch, pain, body posi...

Protoplasmic streaming, ciliary movements, movements of fins, limbs, wings, etc., are some forms exhibited by animals. The skeletal system is a complex network of bones and connective tissues, including cartilage, tendons, and ligaments, which provides structure and support for the body. It also serves several vital functions, such as providing movement, producing blood cells, protecting organs, and storing minerals. There are 206 bones in the human skeletal system, and each bone is composed of three main layers: the periosteum, compact bone, and spongy bone. Other components of the skeletal system include cartilage, joints, ligaments, and tendons. The skeletal system allows the body to move by providing support and structure. The bones of the skeleton provide structure and support to the muscles, which enable movement. The jo...

Respiration in Plants Mind map Class 11 chapter 14 NCERT for NEET AIIMS and class 11 PDF is at end of this page👇👇 Plants unlike animals have no special systems for breathing or gaseous exchange. Stomata and lenticels allow gaseous exchange by diffusion. The breaking of C-C bonds of complex organic molecules by oxidation cells leading to the release of a lot of energy is called cellular respiration. Almost all living cells in a plant have their surfaces exposed to air. Respiration in plants is the process in which plants absorb free oxygen molecules to produce water, carbon dioxide, and energy, which is required for plants to grow. The process of respiration in plants involves using the sugars produced during photosynthesis plus oxygen to produce energy for plant growth. In this article, we will discuss the role of air temperature, the importance of oxygen for roots, ideal root zone conditions, and the importance of air in organic substrates. We will also explain the processes of tran...

Photosynthesis in Higher Plants Mind map Class 11 chapter 13 NCERT  PDF is given at end of this page 👇👇 Green plants make their own food by photosynthesis.  During this process carbon dioxide from the atmosphere is taken in by leaves through stomata and used for making carbohydrates, principally glucose and starch. Photosynthesis takes place only in the green parts of the plants, mainly the leaves.  Within the leaves, the mesophyll cells have a large number of chloroplasts that are responsible for CO2 fixation.  Within the chloroplasts, the membranes are sites for the light reaction, while the chemosynthetic pathway occurs in the stroma.  Photosynthesis has two stages: the light reaction and the carbon fixing reactions.  There are two photosystems, PS I and PS II. PS I has a 700 nm absorbing chlorophyll a P700 molecule at its reaction centre, while PS II has a P680 reaction centre that absorbs red light at 680 nm. Photosynthesis is the process by which hi...

PDF is given at end of this page 👇👇 The Science of How Plants Grow As we’ve previously mentioned, plants grow according to three basic principles: photosynthesis, growth, and dormancy. These rules of nature are known as the science of how plants grow. When a plant reaches maturity, it produces its first leaves and develops its main stem. Once this happens, it’s called plant development. Plant hormones (or phytohormones) are signal molecules, produced within plants, that occur in extremely low concentrations. Plant hormones control all aspects of plant growth and development, from germination to flowering. We'll cover five major types of plant hormones: auxin, gibberellin, cytokinin, ethylene, and abscisic acid. These hormones can work together or independently to influence plant growth. Auxin is involved in cell growth and cell expansion, so it is produced primarily in parts of the plant that are actively growing like the stem. Gibberellin causes some similar effects in plants as...

PDF of the Mind Map if given at end of this page 👇👇 NCERT Solutions for Class 11 Chapter Transport in plants - Question 1- What are the factors affecting the rate of diffusion? Answer: Factors affecting diffusion are -  Concentration gradient, Permeability of membrane; separating the substance, Temperature and Pressure. Question 2 - What are porins? What role do they play in diffusion? Answer: Special type of protein called Carrier proteins form porin channels in the outer membranes of plastids, mitochondria and some bacteria. The porin channels allow the molecules to pass through membrane. Molecules stick to the transport protein and are transported by facilitated diffusion. Question 3 - Describe the role played by protein pumps during active transport in plants. Answer: Protein pumps are used to transport substances against a concentrations gradient. This is a type of active transport. Active transport is carried out by membrane proteins. Pumps are proteins which use energy to ...

Oxygen is used by all organism to break down nutrient molecules like protein, glucose and fat to derive energy and use that energy to perform various activities. The process of exchange of oxygen from the atmosphere with carbon dioxide produced by the body is called breathing which is commonly known as respiration. Different type of organism have different ways for respiration. Respiratory organs like gills are used by aquatic arthropods and molluscs. Lungs are present in terrestrial organisms for exchange of gases. Image credit: NCERT Biology class 11 Respiratory volumes - Tidal volume (TV) : Volume of air taken in/given out during normal respiration = 500 mL. Inspiratory Reserve Volume (IRV) : Additional volume of air inspired by forcible inspiration =  2500mL to 3000mL. Expiratory Reserve Volume (ERV) : Additional volume of air, a person can expire by a forcible expiration. Residual volume (RV) : Volume of air remaining in the lungs even after a forcible expiration = 1100 mL...

Note : PDF is at end of this page👇👇 Blood is a special connective tissue which is used to transport substances like enzymes, gases and waste materials from one part of the body to other. Blood consists of two major parts - plasma and formed elements. 55% of the blood is plasma while formed elements constitute 45% of the blood.  Plasma is a liquid part of blood which is straw coloured liquid. 90 to 92% of plasma is water and 6 to 8% is protein. Plasma have three types of protein albumin, globumin,  Blood plasma without clotting factor is known as  serum. Red blood cells are also called erythrocytes. In blood there are about 4.5 to 5.5 million RBCs per  millimetre cube of blood. RBC are red color,  circular, biconcave cells. RBCs don't have nucleus, that is there enucleated. This is because all of the inner space in RBC is used to carry oxygen. RBCs also lack cell organelles like endoplasmic reticulum, ribosomes, mitochondria etc. RBCs are formed in red bone mar...

Human physiology contains a total of 7 chapters in NCERT textbook. The first chapter is digestion and absorption which tells us about our digestive system. The process of conversion of complex food materials into simple forms is called digestion. Human digestive system is divided into two parts -  the alimentary canal and the associated glands. Our digestive system is complete with two openings - anterior mouth and posterior anus. The mouth leads to oral cavity also known as buccal cavity. This cavity contains teeth and tongue. There are three pairs salivary gland situated just outside the buccal cavity. These are sub maxillary gland (in on the lower jaw) parotid gland (on the cheeks) and sub lingual gland (under the tongue). The secretions from the salivary gland comes to buccal cavity through ducts. The Saliva mainly consist of salivary amylase, some ions like sodium ion potassium ion etc. and Lysozyme enzyme. 30% of the total starch is converted into glucose in mouth by using sa...

Mind map is given at end of this page👇👇 Cell cycle and cell division is chapter 10 of class 12th NCERT biology. This chapter tells about how a cell divides and what is cell cycle. Sequence by which cell duplicates its genome, synthesize other constituent of cell and finally divides into two is known as cell cycle. The cell cycle is the process by which a cell grows, replicates its DNA, and divides into two daughter cells. It is made up of four distinct phases: G1 (Gap 1), S (Synthesis), G2. The cell cycle is the process by which cells divide and reproduce. It is an essential part of life and allows for the growth, development, and maintenance of all living organisms. The cell cycle consists of four distinct phases: interphase, mitosis, cytokinesis, and G0 phase. During each phase, different processes take place to ensure that cells can divide accurately and efficiently. Interphase is the first stage of the cell cycle. During this stage, a cell grows in size and prepares for DNA repli...
