The female cell which must be impregnated by a sperm in sexual reproduction.
An organism in the earliest stage of growth.
What is an Embryo? p. 124.
Genetic material holding its food supply protected by a seed coat.
A vascular plant that reproduces with spores.
What is a Fern? p. 121.
Grows taller than mosses and liverworts in moist, shaded areas. Some grow up to 25 meters in the tropical forest.
The joining of the egg & sperm.

p. 118
male cells produced in the testes.
Plants that have tubelike cells in their roots, stems, and leaves to carry food and water.
