Question

Why are air and soil important for germination of a plant class 5

Answer 1

Answer:

Seed germination may be defined as the fundamental process by which different plant species grow from a single seed into a plant. This process influences both crop yield and quality.

A common example of seed germination is the sprouting of a seedling from a seed of an angiosperm or gymnosperm.

Oxygen: It is an important and essential source of energy required for seed growth. It is required by the germinating seed for the metabolism and is used as a part of aerobic respiration until it manages to grow green leaves of its own. Oxygen can be found in the pores of sand particles, but if the seed is buried too deep it will be deprived of this oxygen.
