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 tides are influenced by both the moon and the sun, it's easy to see that when the sun lines up with the moon and the earth, as during a new moon or full moon, the tidal effect is increased. these are known as spring tides, named not for the season, but for the fact that the water "springs" higher than normal. on the other hand, if the sun and the moon are 90 degrees apart in relation to an observer on earth as during the first quarter moon or third quarter moon, then high tides are not as high as they normally would be. this is because despite its greater distance, the sun's mass allows it to exert enough gravitational force on the oceans that it can negate some of the effects of the moon's pull. this phenomenon of lower high tides is called a neap tide. if you need more information on this topic visit moonconnection.com.
