We have seen a lot of bad micro-organisms in previous chapters. However other than plants and animals, a lot of microbes form a major component of biological system on earth. Micro-organisms like bacteria fungi and virus are present everywhere from soil to water and even inside our bodies. These can be found in ice cold environment as well as hot environments were temperature maybe as high as 100 degree Celsius. Microbes in household products - We use microbes in lot of daily to daily processes. For example milk is converted into curd by a bacteria called lactobacillus or lactic acid bacteria (LAB). Also bakers use fungus Saccharomyces cerevisiae to get soft bread. Hence this yeast is also called as bakers yeast. Swiss cheese has large holes due to Carbon dioxide production by a bacteria known as Propionibacterium sharmanii. A very famous cheese called Roquefort cheese is right and by growing fungus Penicilliam roqueforti on it. Microbes in industries - Saccharomyces cerevisiae is also...

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...

Flowering plants are also known as angiosperms because they are only kind of plants that produce flower. In the classification system given by RH Whittaker, there are five types of plants that we have to study for class 12th or neet exam. These are algae Bryophytes, Pteridophytes, Gymnosperm and Angiosperm.  Flowers are used since long time to convey important feelings such as love, happiness,  affection, grief, peace, etc. For angiosperm plants, flowers are the site of sexual reproduction. The flowers can have both male and female sex organs or they can be unisexual. Typical flower have four whorls, these are - Calyx, Corolla, Gynoecium and Androecium.

The male reproductive organ have stamen which have two part - anther and filament. The anther is a bilobed, dithecous...

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...

So here's the mind map of Cell : The unit of life. This is chapter 8 of class 12. This mind map is 100% from NCERT and nothing extra is put from outside. The main topics to study in this lesson -  1. What is a Cell? 2. Cell Theory 3. An Overview of Cell 4. Prokaryotic Cells 5. Eukaryotic Cells Cell was discovered by Robert Hooke and Anton von Leeuwenhoek was first person to saw a living cell. Nucleus was discovered by Robert brown. There are two types of cell based on presence or absence of nuclear membrane. The cell which doesn't have nuclear membrane is known as prokaryotic cell and cell which have nuclear membrane is known as eukaryotic cell. Cell theory was given by 2 scientists - Schleiden and Schwann. Rudolph Virchow observed that a cell arises from pre existing cell. He also contributes to cell theory. Prokaryotic cell includes bacteria, blue green algae or cyanobacteria, mycoplasma. Mycoplasma is the smallest living organism that is found on earth. All prokaryotes have ...

This is chapter 7 of class 11 biology. In this lesson we learn about different lecel of organization in animals.  Main topics to study in this chapter - 1. Animal Tissues 2. Organ and Organ System 3.Earthworm 4.Cockroach 5. Frogs However, it is not clear if Frog is in syllabus for NEET exam. Still, this mind map has detailed information of all 3 organisms ie. Earthworm, Cockroach and Frog. The mind map is very short and to the point. It will take about 15 minutes only to complete this complex chapter from the mind map.  It's surprising that all complex animals consist of only four basic types of tissues. These are -  Epithelial tissue, Connective Tissue Muscle tissue and Nueral tissue .  Epithelial tissues are sheet like tissues lining the body surface, ducts and tubes. Epithelia have one free surface facing a body fluid or the outside environment. Connective tissues bind, support, and connect other tissue in the body. Soft connective tissues consist of protein f...

Anatomy means study of Internal features . This includes internal organs, types of tissues, different types of cells that are found in an organism. In this chapter, we study Anatomy of flowering plants, that is Angiosperms . Angiosperms are the only type of plants that produce flower. The main topics of this chapter are-  1. The Tissues 2. The Tissue System 3. Anatomy of Dicotyledonous and Monocotyledonous Plants 4. Secondary Growth The tissue is a group of cells having a common origin and performing a common function. Types of tissue - Meristematic Tissues and Permanent tissue,  Simple tissue and Complex tissue.  Vascular bundles having Xylem, Phloem are important for exam. Also, different types of cells like Parenchyma, Collenchyma and schrelenchyma are also important.  Then NCERT explains Tissue systems. These are - Epidermal Tissue systems, Ground tissue system and Vascular tissue system.  Then we study anatomy of root and stem of dicot and monocot pla...
