Module 12
The study of life processes on an organism.
Physiology
The parts of a plant (such as flowers, fruits, and seeds) involved in reproduction.
Reproductive plant organs
Three types of ground tissue.
Parenchyma, collenchyma, sclerenchyma.
Two kinds of root systems in plants.
Fibrous root systems and taproot systems.
The parts of a plant (such as stems, roots, and leaves) that are not involved in reproduction.
Vegetative organs
Tiny wholes on the underside of most leaves.
Stomata
The process of cutting away a ring of inner and outer bark all the way around a tree trunk.
Girdling
Provides storage for starches and oils that the plant needs.
Parenchyma
The outer covering of a plant and is generally made out of a single layer of cells.
Nonliving vascular tissue that carried water and dissolved minerals from the roots of a plant to its leaves.
Xylem
The difference between monocot and dicot stems.
Presence of a vascular cambium
A plant that loses its leaves for winter.
Deciduous plant
Made of living cells with unevenly thickened cell walls that help to support young stems, roots, and petioles.
Collenchyma
Used to carry water and dissolved material throughout the plant.
Vascular Tissue
Living vascular tissue that carries sugar and organic substances throughout a plant.
Phloem
Performs these three basic functions in a plant.
1. Support and manufacture that plant's leaves.
2. Conduct water and nutrients to and from the leaves.
3. Carry on photosynthesis.
A plant's response to a stimulus such that the direction of the response is preprogrammed and not dependent on the direction of the stimulus.
Provides rigid support and protection.
Sclerenchyma
Four processes for which water is used in a plant.
Photosynthesis, turgor pressure, hydrolysis, and transport.
Spaces in the soil that determine how much water and air the soil can hold.
Pore spaces
Four basic kinds of plant tissue.
Meristematic, ground, dermal, vascular.
The process by which organic substances move through the phloem of a plant.
Translocation
A growth response to light
Phototropism
A growth response to gravity
Gravitropism
A growth response to touch.
Thigmotropism
