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.

The answer is 1, either ( AA, Aa, or aa ) .
To calculate the energy offered from food, multiply the number of grams of protein, carbohydrate, and fat by 4, 4, and 9, respectively.
Then add the results together.
Given: 500 grams of carbohydrates, 30 grams of protein, and 75 grams of fat in one day.
500 grams x 4 kcal/g = 2000 kcal
30 grams x 4 kcal/g = 120 kcal
75 grams x 9 kcal/g = 675 kcal
= 2795 kcal
From this data, you can calculate the percentage of k calories each of the energy nutrients give to the total.
Solution:
2000/2795 * 100% = 72% from carbohydrates
120/2795 * 100% = 4% from protein
675/2795 * 100% = 24% from fat
Total: 100%
Your correct answer is D metals!
