Question

The diploid number for a lily whose pollen contains 12 chromosomes would be _________ and is produced when the pollen, containing sperm, _______ the egg.

A)6: fertilizes
b. 12: pollinates
c. 24: pollinates
d. 24: fertilizes

Answer 1

A)6: fertilizes

Meiosis is the process of cell division by which involving gametes. Cell division is just the same for sperm and egg cells, but they have distinguishable descriptions and labels in the process. Spermatogenesis is for the males’ sperm cells and oogenesis is the process for females’ egg cells.

12 chromosomes for diploid becomes 6 for the sperm cell

Answer 2

D The diploid number for the lily would be 24 and is produced when the pollencontaining sperm fertilizes the egg. The pollen is the male gamete for the flower. If it contains 12 chromosomes, the the egg would also contain 12 chromosomes. After the process of fertilization occurs, the new cell would have 24 chromosomes, half from the pollen and half from the egg.
