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?
