A life cycle with both a multicellular diploid form (sporophyte) and a multicellular haploid form (gametophyte), characteristic of plants and some algae.
The multicellular diploid form in alternation of generations that produces haploid spores by meiosis.
The multicellular haploid form in alternation of generations that produces haploid gametes by mitosis.
Occurs in the sporophyte to produce haploid spores that develop into gametophytes.
Union of two haploid gametes to form a diploid zygote, which develops into a multicellular sporophyte.
The aerial part of a plant body, including stems, leaves, and reproductive structures like flowers.
All of a plant's roots, anchoring it and absorbing water and minerals from the soil.
A bud at the tip of a plant stem responsible for primary growth and elongation.
A bud located in the angle between a leaf and stem that can form a lateral shoot or branch.
Node: Point on a stem where leaves attach. Internode: Stem segment between nodes.
Includes blade (flat part), petiole (stalk attaching leaf to stem), and is the main photosynthetic organ.
The ovule-producing reproductive organ of a flower, consisting of stigma, style, and ovary.
The pollen-producing reproductive organ of a flower, consisting of anther and filament.
A modified leaf that encloses and protects a flower bud before it opens.
A modified leaf often colorful to attract pollinators.
The transfer of pollen to the part of a seed plant containing ovules, required for fertilization.
An adaptation packaging an embryo with food supply inside a protective coat, aiding survival on land.
Growth produced by apical meristems that lengthens stems and roots.
Growth produced by lateral meristems that thickens roots and shoots, common in woody plants.
Vascular tissue consisting mainly of dead cells that conduct water and minerals upward from roots.
Vascular tissue consisting of living cells that transport sugars and organic nutrients throughout the plant.
