- Root: An organ that anchors a plant to its surface and enables it to absorb water and its nutrients from the soil.
- Root Hair: Tiny lateral extension of a root's cells that absorbs water and minerals from the soil.
- Stem: Connects a plant's roots to its leaves and flowers; it provides the structural support for the plant.
- Leaf: Flat structure attached to the stem, where photosynthesis occurs and food molecules are made.
- Flower: Part of a plant that is used for sexual reproduction; it produces seeds and fruit.
- Terminal Bud: Stems growing tip.
- Axillary Bud: Growing tip that can add side branch to the plant.
- Node: Place on the stem where leaf attaches.
- Internode: Space between nodes.
- Bulb: Short, underground stem with fleshy leaves that store nutrients and food.
- Seeds: A plant embryo surrounded by a protective coating.
- Endosperm: Cells that surround a plant embryo and form the bulk of the seed.
- Seed Coat: A protective cover over the seed that keeps it from dying out.
- Fruit: Any structure that develops from a flower's ovary. (Bozzone 188-193).
- Monocot: Flower parts in multiples of tree. Major leaf veins parallel.
- Dicot: Flower parts in multiples of four or five. Major leaf veins reticulated.
Bryophyte: Bryophyte is a traditional name used to refer to all embryophytes that do not have true vascular tissue and are therefore called "non-vascular plants". Ex: moss.
Sporophyte: Is the diploid multicellular stage in the life cycle of a plant or alga. It develops from the zygote produced when a haploid egg cell is fertilized by a haploid sperm and each sporophyte cell therefore has a double set of chromosomes, one set from each parent. All land plants, and most multicellular algae, have life cycles in which a multicellular diploid sporophyte phase alternates with a multicellular haploid gametophyte phase. In the seed plants, the Gymnosperms and flowering plants(Angiosperms), the sporophyte phase is more prominent than the gametophyte, and is the familiar green plant with its roots, stem, leaves and cones or flowers. In flowering plants the gametophytes are very reduced in size, and are represented by the pollen and the embryo sac.
