Grade 11 University Biology – Unit 5 Plants – Jeopardy 1 Plant Hormones Sexual Reproduction Transport in Plants Plant Organs Plant Cells 1 2 3 4 5
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 is Apical Meristem?
Undifferentiated embryonic plant tissue from which all other plant tissue develop
What is Meristematic 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 is Collenchyma Cells?
Most plants cells have this one large part that is used primarily for storage
What is Vacuole?
