The hormones that stimulate the elongation of plant cells

What are Auxins?

This gaseous hormone weakens the cell wall of

unripe fruit and breaks down starches into simple sugar to

speed up the ripening process

What is Ethylene?

This hormone stimulates rapid cell division, and as

such, rapid growth

What are Cytokinins?

A hormone used by plant growers and farmers to increase fruit size and

increase the cluster size of grapes

What are Gibberellins?

A chemical compound produced in one part of the plant that controls growth

activity in another part of the plant

What is a Hormone?

The transfer of pollen grain to the pistil

What is Pollination?

The male reproductive part of the flower

What is the Stamen?

An angiosperm plant where the embryo has one

cotyledon

What is Monocot?

The process by which growth resumes in a seed after a period of being dormant

What is Germination?

The angiosperm with vascular bundles that are arranged in a circle in the

middle of the stem surrounding a central pith

What is Dicot?

The mechanism by which positive pressure in the roots

moves water upward in the plant

What is Root Pressure?

The force of attraction between water molecules that tends to have the molecules

stick together

What is Cohesion?

The movement of water across a membrane in living

system from an region of high water concentration to an

area of low water concentration

What is Osmosis?

This process reduces in conditions of high humidity

What is Transpiration?

The transport of sucrose and other organic molecule

through the phloem

What is Translocation?

A protective covering on the tip of the root

What is Root Cap?

A row of tightly packed parenchyma cells in the

leaves that contain many chloroplasts and where most

photosynthesis occurs.

What is Palisade Mesophyll?

The main function is to provide support for leaves

and the reproductive structures

What is the Stem?

A waterproof band that surrounds the endodermis (layer of cells between the

cortex and the vascular tissue) of the root. The band creates a barrier to water and dissolved water movement

What is Casparian strip?

These fibrous extensions from the root

increase the surface area for uptake of water

and minerals

What is Root Hair?

The tips of the root and stems where cell division

occurs rapidly

What isApical Meristem?

Undifferentiated embryonic plant tissue

from which all other plant tissue develop

What isMeristematic Tissue?

These green organelles do not

occur in animal cells

What are Chloroplasts?

This cell type is often elongated with thickened cell walled, and the cells are primarily support for

surrounding cells

What isCollenchyma Cells?

Most plants cells have this one large part that is

used primarily for storage

What is Vacuole?
