Which part of a seed plant develops into sperm cells?

embryo
pollen
seed
xylem

Pollen

Explanation:

The pollen is a component of the male part of a seed plant.

A) Embryo; wrong because this is the female part. Female organisms do not produce sperm.

C) Seed; this is the compartment that keeps the embryo safe; it doesn't produce sperm.

D) Xylem; wrong because this is a vascular tissue, which has nothing to do with fertilization, reproduction, and males vs. females.

Hope this helps!

Pollen

Explanation:

Pollen are the male reproductive part.

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
