Biology

5 0

Answer:

B

Explanation:

Great variations in temperature and pH from the optimum that an enzyme needs can affect its function. pH affects ionization of the functional groups of amino acids. The interaction of charges of these amino groups helps in stabilizing loops such as those of beta sheets and alpha helices and give the protein its an appropriate shape to function.

Temperatures, on the other hand, while it does not change the ionization of the functional side groups of amino acids, it breaks these bonds of the interactions by giving the molecules enough energy to break free from these bonds hence denaturing the protein.

What organelles do plants have in their roots that helps them to sense gravity?
harina [27]

statocytes, organelles do plants have in their roots that helps them to sense gravity, correct answer is B.

what are statocytes ?

In higher plants, statocytes are the cells which sense gravity. They contain amyloplasts-statoliths, amyloplastic organelles which are filled by starch or sediment at the bottom of the cells. Coleoptiles, shoots, and inflorescence stems all have an elongating area that really is home to statocytes.

how do they help in sensing gravity ?

When the plant is reoriented in the gravity field, the starch-filled plastids (also known as statoliths) in the statocytes, that are highly polarized cells, fall to the physical bottom.

Hence, statocytes help in sensing gravity.
