In animals, meiosis results in gametes, and fertilization results in gametophytes.?

Question

A) True

B) False

Answer 1

B)

Meiosis- Four haploid cells (gametes)

Fertilization-Zygote

Answer 2

False. Meiosis is the formation of haploid (possessing a single copy of a chromosome) gametes (s*x cells) by the splitting of a germ-line cell.

   Syngamy (fertilization) is the combining of two haploid gametes ( A sperm and an egg. You get the idea) to produce a ZYGOTE. The zygote then undergoes serveral repetitions of MITOSIS. Mitosis is the division of a diploid cell (In this case the zygote) to produce an exact copy of itself.

After the zygote has multiplied into enough cells, differentiation occurs. During differentiation certian cells are set aside so that in the future they can perform a specific job. For example  a group could be set aside to be blood cells or bone cells. There is also a specific number of cells that are set aside to become GERM-LINE CELLS, which will eventually undergo meiosis and produce gametes.

It's just like a big cycle.

Meiosis makes gametes.

Two gametes make a zygote.

A zygote makes germ-line cells.

Mitosis turns germ-line cells into gametes.

Answer 3

false. fertilisation results in zygotes.
