1) They produce food for all organisms 2) They provide beneficial substances like drugs, tannins, fibres, rubber, vegetable oils, fuel, condiments. 3) Some plants contain alkaloids which check growth of cancer cells. Example: Rosy periwinkle. 4) Plants release O 2 , cool environment by r..

At the cellular level, growth is the increase in the amount of protoplasm (nuclues + cytoplasm). During growth, the synthesis of complex molecules like proteins nucleic acids and carbohydrates is at a higher rate than the rate at which the complex molecules are broken down. Duri..
