Question

Extreme environmental conditions such as heat and cold may affect the timing of a mature seed's

Answer 1

Ans. Germination.

Seed germination can be defined as a process, which involves growth of a mature plant from a seed. It is affected by many both internal and external environmental factors. Environmental factors that affect the seed germination include temperature, oxygen, and water.

Temperature affects seed germination by affecting growth rate and cellular metabolism. Seeds of different plants depend on different temperature for germination.

For examples, seeds of annual vegetables germinate at hot temperature (between 75-90 F), while seeds of spinach and reddish germinate at cold temperature (at 40 F).

Thus, the correct answer to complete the given statement is 'germination.'

Answer 2

The correct answer to the question above is Germination. An extreme environmental condition such as heat and cold may affect the timing of a mature seed's germination. Germination is a biological process in which the seeds are outgrowing into a plant.
