PlantsPlants

Plant cell with thin walls responsible

for metabolic reactions including

photosynthesis

Parenchyma

Part of the root that contains

xylem and phloem

Vascular Cylinder/Stele

Type of plant response that

orients a plant to light

Area of lateral or secondary growth

in stems

Vascular Cambium

Type of plant cell that provides

support during growth

Collenchyma

Part of a leaf adapted for maximum

absorption of sunlight

Blade

What constitutes most of the wood

in a tree

Secondary Xylem

Process of water uptake and loss by

plants

Transpiration

What can be used to measure how water flows in a

plant

Water Potential

Type of flowering plant with netlike veins, a taproot

and vascular bundles in a ring

Dicot

Areas of active cell division in plants

Meristems

Sugar loading in phloem cells involves this

Cotransport

Waxy layer in endodermis that keeps water in

Auxin

Hormone responsible for fruit ripening

Ethylene (only hormone that

is a gas)

Tissue in plants that moves

substances like water and sugar

Vascular

Tissue in plants that primarily

stores things and supports the plant

Ground tissue

Part of angiosperms

responsible for reproduction and not found in any other major plant

groupFlower

Group ancestral to modern plants or

group that modern plants evolved

from

Charophycean green algae

Group of plants in which the

gametophyte generation is

dominantBryophytes (mosses)

Group of seedless vascular plants

Pteridophytes (ferns )

The power source for transpiration in

plants

The Sun

Water properties that aid

transpiration in plants

Adhesion, cohesion

Stomates or Guard cells

These control how much water is lost due to transpiration as well as rate of photosynthesis

stamen

Female part of the flower

Carpel

The ovule in a flower becomes a

seed

Triploid tissue in a seed

endosperm

Male and female flower parts maturing at

different times prevent this

Self-pollination

How the sperm reaches the egg in flowering plants

Pollen tube

Loss of micronutrients like

magnesium can result in this,

when not enough chlorophll is made

chlorosis

Plants get nitrogen they need primarily through

this process

Nitrogen fixation by bacteria

Three macronutrients in

plantsNitrogen,

phosphorus, potassium

Growth in apical meristems is

typically referred to as______growth

Primary

Two major plant groups whose

sperm are flagellated and

require water for fertilization
