Plant Biology Terms

Angiosperm

• A type of non-flowering plant that reproduces via spores.

• A group of flowering plants that produce seeds enclosed within a fruit.

• A category of plants that have no vascular tissue.

• A type of plant that grows only in aquatic environments.

Gymnosperm

• A group of flowering plants that produce seeds enclosed in a fruit.

• A group of seed-producing plants that includes conifers, cycads, Ginkgo, and gnetophytes. They do not form flowers.

• A type of plant that reproduces through spores instead of seeds.

• A category of plants that primarily grow in aquatic environments.

Vascular plant

• A type of plant that has a vascular system, including xylem and phloem, for transporting water and nutrients.

• A type of plant that reproduces using spores instead of seeds.

• A type of plant that grows in aquatic environments and has floating leaves.

• A type of plant that does not have any specialized tissues for transport.

Rhizoid

• A type of vascular tissue in plants

• A root-like structure in nonvascular plants that anchors the plant and conducts water.

• A reproductive structure in flowering plants

• A type of leaf structure in ferns

Ovary

• The part of the pistil which holds the ovules and is located above or below or at the point of connection with the base of the petals and sepals.

• The outer layer of the flower that protects the petals.

• The structure that attracts pollinators with its color and scent.

• The part of the flower that produces pollen.

Petal

• The reproductive part of a flower.

• The parts of a flower that are often conspicuously colored. They surround the reproductive parts of flowers.

• The green parts of a plant that photosynthesize.

• The stem of the flower that supports the petals.

Nonvascular plant

• A type of plant that has a vascular system consisting of xylem and phloem.

• A type of plant that does not have a vascular system consisting of xylem and phloem.

• A type of plant that primarily grows in aquatic environments.

• A type of plant that reproduces only through seeds.

Phloem

• The vascular tissue in plants that conducts sugars and other metabolic products downward from the leaves.

• The tissue responsible for water transport in plants.

• The outer protective layer of a plant's stem.

• The part of the plant that absorbs nutrients from the soil.

Stamen

• The pollen-producing reproductive organ of a flower, usually consisting of a filament and an anther.

• The part of the flower that attracts pollinators with its color and scent.

• The structure that supports the petals of a flower.

• The green part of the flower that protects the bud before it opens.

Pollination

• The process of transferring pollen from the male part of a plant to the female part of a plant, enabling fertilization to occur.

• The process by which plants produce seeds without the need for pollen.

• The method by which plants absorb water through their roots.

• The process of photosynthesis in plants.
