What is germination? Explain the different stages.
Answers
Answer:
Germination is usually the growth of a plant contained within a seed; it results in the formation of the seedling. It is also the process of reactivation of metabolic machinery of the seed resulting in the emergence of radicle and plumule.
1) Imbibition: water fills the seed. 2) The water activates enzymes that begin the plant's growth. 3) The seed grows a root to access water underground. 4) The seed grows shoots that grow towards the sun. 5) The shoots grow leaves and begin photmorphogenesis.
Answer:
Germination is the process by which an organism grows from a seed or similar structure.
Such five changes or steps occurring during seed germination are:
1) Imbibition
2) Respiration
3) Effect of light on seed germination
4) Mobilization of reserves during seed germination and role of growth regulators and
5) Development of Embryo Axis into seedling
