Plant Biology Vocabulary

Flashcards covering essential vocabulary related to plant structure and response.

Dermal Tissue

The protective outer layer of a plant.

Vascular Tissue

Tissue responsible for the transport of water and nutrients in plants.

Ground Tissue

Plant tissue that is neither dermal nor vascular; responsible for photosynthesis, storage, and support.

Root System

The part of a plant that typically grows underground and anchors the plant while absorbing water and nutrients.

Shoot System

The aerial part of a plant, consisting of stems and leaves.

Phloem

The vascular tissue that transports sugars and nutrients produced by photosynthesis.

Xylem

The vascular tissue that transports water and minerals from the roots to the rest of the plant.

Geotropism

The growth response of a plant to gravity.

Thigmonasty

A plant's response to touch stimuli, resulting in movement.

Photonasty

A plant's response to light, resulting in movement.

Thigmotropism

The directional growth of a plant in response to touch, such as climbing plants wrapping around supports.

Phototropism

The growth of a plant towards light.

Tropism

Any growth or movement of a plant in response to an environmental stimulus.
