Dernst AP biology Plant #2

brassinosteroids

photoreceptors that mostly absorb red light

type of cell that Performs most of the metabolic functions of the plant

loses fluidity and crystallizes lipids

water conducting cells of the xylem

type of cells that provide flexibility of the stems

circadium rhythm

auxin

type of cell where photosynthesis takes place

cell type that stops growing in length when mature

Leads to stem elongation, plays a role in tropism and gravitropism, popular for AP testing

gibberellins

ethylene

process by which plants lose water by evaporation

cytokins

phytochrome absorbs which colors

promote cell division and leaf enlargement

Which of these materials is transported by xylem?

With what phenomenon is phytochrome associated?

Induces growth of dormant seeds, buds, and flowers

denatures proteins within the plant

Regulates plants responses to seed germination and shade avoidance

water loss exceeds water absorption resulting in death of the plant

Biological clock for plants

Inhibits cell growth and stimulates the closing of the stomata

Suffocates the plant because the soil lacks air spaces to provide oxygen

water to water bonding being pulled up through the stem by negative pressure of transpiration

A vine wraps around a tree as it grows in the forest. This is an example of?

Which contributes most to the movement of water through xylem.

sugar conducting cells

initiates fruit ripening and causes flowers and leaves to drop from trees

type of cells that are grouped in strands and support young plant shoots

process by which plants make their energy

abscisic acid

cell type that provides support and strength to the plant

Force of adhesion between water and passageway that pulls water up the sides

Which of the following is found in phloem tissue?

blue-light receptors?

lowers water potential and water loss even thought there is plenty of water in the soil
