Antheridium - The male sex organ of terrestrial plants; where sperm cells are generated. Archegonium - The female sex organ of terrestrial plants; where egg cells are produced. Autotroph - An organism that synthesizes its own organic nutrients and does not rely on other organisms for food. Diploid - Having two sets of chromosomes, one from each parent. Epidermis - The outer layer of cells found on the body wall of an organism. Gamete - A haploid sex cell (either an egg or sperm cell); male and female gametes join during fertilization to create a diploid zygote. Gametophyte - A haploid plant or plant structure that produces haploid gametes through mitosis. Haploid - Having only one set of chromosomes.

Root - The part of a plant beneath the soil; responsible for collecting water and minerals from the soil, storing nutrients, and securing the plant to the ground. Shoot - The part of the plant above the soil, including all aerial structures such as stems, leaves, flowers, and fruits; gathers carbon dioxide and light energy for photosynthesis, provides surfaces for gas exchange, and contains the plant's reproductive organs. Spore - Haploid cell from which a gametophyte is produced. Sporophyte - A diploid plant or plant structure that produces haploid spores through meiosis. Stoma - A very small epidermal pore, surrounded by two guard cells, through which gases diffuse in and out of a leaf....
