NEET Biology Transport In Plants Chapter Notes Set A

 A plant cell has three physiological compartments – cell wall, protoplast and vacuole. Two membranes separate these compartments tonoplast around central vacuole and plasmolemma around protoplast and is attached to cell wall. Both membranes are selectively permeable. Central vacuole contains an osmotically active fluid called sap. Plant cell forms a living continuum called simpleast with the help of plasmodesmata which functions as cytoplasmic bridges between adjacent cells. A non-living continuum called apoplast also occurs in plants.

NEET Biology Reproduction In Organism Chapter Notes

 Reproduction is a biological process in which an organism gives birth to offspring similar to itself.
 Reproduction enables the retention continuity of the species, from generation to generation. The genetic variation is created and inherited during reproduction.
 When offspring is produced by a single parent without the involvement of gamete formation, the reproduction is called asexual.

NEET Biology Reproduction Health Chapter Notes

REPRODUCTIVE HEALTH

Reproductive health is a state of physical, emotional, behavioural and social fitness for leading responsible, safe and satisfying reproductive life. Briefly speaking reproductive health refers to healthy reproductive organs with normal functions. World Heath Organisation ( WHO ) has defined reproductive health as total well being in all aspects of reproduction, its emotional, behaviroral and social aspects along with the physical one.

NEET Biology Plant Growth And Movement Chapter Notes

 Growth is a process in which there is increase in the size by cell division and enlargement accompanied by the formation of new cellular material. It results in the irreversible increase in size, length area or volume accompanied by
increase in dry weight. In living beings, growth is internal or intrinsic in contrast to extrinsic growth observed in some non-living objects. Irreversible increase in size, mass or volume of living beings is an external manifestation of growth.

NEET Biology Photosynthesis Chapter Notes

 Photosynthesis is simply defined as “ formation of carbohydrates from CO2 and H2O by illuminated green cells of plants, O2 and H2O by being the byproducts”. In other words, capture of photons of light by green plant cells and conversion of their radiant energy into chemical form of energy is called photosynthesis.
