Explanation:
Inside the amyloplasts of the common bean the starch granules resemble variously sized cotton balls stuffed into a balloon. Under normal circumstances amyloplasts do nothing more than sit on the bottom of special gravity-sensing cells. When a plant is knocked over, the amyloplasts slide from what was recently the bottom of the cell onto a formerly vertical wall. Somehow, this movement is sensed and relayed to cells that secrete the growth-regulating plant hormone auxin.
Since the plant has lost the ability to transform glucose into the granules. The plant can´t differentiate between up or down because gravity is what causes these granules to settle down.
The answer is; B
During metaphase I of Meiosis I , homologous sister chromosomes line up the metaphase plate in pairs. During anaphase I, the sister chromosomes of the pairs are separated and move to opposite poles. This way, the resulting daughter cells have half the chromosome number as the parent cell.
Answer:
Double fertilization involves two sperm cells; one fertilizes the egg cell to form the zygote, while the other fuses with the two polar nuclei that form the endosperm. After fertilization, the fertilized ovule forms the seed while the tissues of the ovary become the fruit.
