Question

What is/are the main factor(s) that determine(s) the height of a plant (genetics, environment, or both)? Explain your answer.




I think that only genetics play a role but I am not sure.

Answer 1

Both. Obviously, genetics plays a major role, but environment does too. My tuberous begonias on a shaded balcony grew tall and leggy in search of sunlight.

Answer 2

I think the environment is important also because if you had dry soil with no nutrients, that could affect the height of the plant and the overall health of the plant.
