Question

What are *microgametophytes* and
*megagametophytes*, and what are their functions in the seed
plant life cycle?

Answer #1

The male gametophyte formed from heterosporous plant
microspores. Gymnosperms and angiosperms are pollen grains which
are **microgametophytes**.

The female gametophyte emerging from a heterosporous plant
megaspore. The **megagametophyte** in angiosperms is
embryo sac.

**Function** :- The microgametophyte (pollen)
travels in seed plants to the vicinity of the egg cell (carried by
a physical or animal vector), and by mitosis produces two sperms.
The megagametophyte consists of several thousand cells in
gymnosperms, and produces one to many archegonies, each with a
single egg cell.

Compare the life cycle of a human to the life cycle of a plant
(alternation of generations).

Describe the life cycle of a flowering plant?

You then cross a plant that is heterozygous for flower
color and seed shape and is homozygous recessive for seed color
with a plant that is heterozygous for flower color and seed color
but is homozygous dominant for seed shape.
a) What is the probability that the off spring from this
cross will be homozygous recessive for all of the
loci?
b) What is the probability that the offspring will have
purple flowers?
c) What is the probability that the...

In a particular species of plant, seed color is determined by a
single gene. Gray seed color is dominant to white seed color. In a
cross, 702 gray seeds and 698 white seeds were produced.
