Cone-bearing plants have the greatest population in the world today.

Gymnosperms are plants that have seed that are not protected by a flower or a fruit.

The female part of a cone-bearing plant is called ovulate cone while the male part is called pollen cone.

When on male gamete meets the egg cell inside the pollen cone, fertilization occurs.

The stage of life where the sori are present is the fern plant's soriphyte stage.

In sexual reproduction, the sperm cell needs to be united with an egg cell in order to form a zygote.

The megaspore develops into male gametophyte.

Fertilization of cone-bearing plants takes place in the ovule.

Mosses reproduce by asexual reproduction.

Spore-bearing plants produce spores in sori.
