Suppose you plant an angiosperm in a pot, which you leave on your porch, and something knocks the pot over on its side. you find that the stems are bent and facing upward, regardless of the amount of sunlight present. which response is most likely being witnessed?
a. thigmotropism
b. photoperiodism
c. phototropism
d. gravitropism

D. Gravitropism

Gravitropism is the response of most plants due to the pull of gravity.

Unlike phototropism, sunlight helps in building up the optimum temperature that is required to start the process of photosynthesis. Water is an important raw material that helps to absorb the carbon dioxide from the air. It also directly influences the opening and closing of the stomata. Carbon dioxide on the other hand is one of the most important raw material that helps to make glucose via the process of photosynthesis.

That is true tge cactus as a structural adaptation to its envirinment has it leaves reduced to spines. but this doesnt mean it cant produce food it produces food because of the presence of chlorophyll in its stem
