Plant Biology Flashcards

Vocabulary flashcards for quick review of plant biology concepts.

Xylem

Vascular tissue that conducts water and minerals, containing tube-shaped cells called tracheids.

Phloem

Vascular tissue that distributes sugars, amino acids, and other organic products.

Roots

Plant organs that anchor plants, absorb minerals and water, and store carbohydrates.

Stems

Plant organs consisting of an alternating system of nodes and internodes.

Leaves

Plant organs that intercept light, exchange gases, dissipate heat, and defend the plant.

Dermal Tissue

Plant tissue that forms a protective outer layer.

Vascular Tissue

Plant tissue that transports water, minerals, and sugars.

Ground Tissue

Plant tissue that includes cells specialized for storage, photosynthesis, and support.

Indeterminate Growth

Plant growth that occurs throughout the plant's life.

Determinate Growth

Plant growth that ceases at a certain size.

Apical Meristems

Located at the tips of roots and shoots, these elongate during primary growth.

Root Cap

Covers and protects the apical meristem as the root pushes through the soil.

Lateral Meristems

Add thickness to woody plants during secondary growth.

Secondary Growth

Process in plants where lateral meristems add thickness to woody plants.

Vascular Cambium

Meristem that makes secondary vascular tissue.

Cork Cambium

Meristem that makes cork cells that accumulate to the exterior of the plant.

Secondary Xylem

Type of vascular tissue produced during secondary growth.

Secondary Phloem

Type of vascular tissue produced during secondary growth.

Cork Cells

Cells that accumulate to the exterior of the plant from the cork cambium.
