Purpose of roots
The two main root purposes
What are to support the plant and look for water?
The purpose of root hairs.
What is to sense water?
What is special about aerial roots? Give one example.
Aerial roots absorb water from the air and grow there roots out of the soil/ground.
Examples: Orchids, vines (of any type), monstera, etc.
The parts of the plant that make up the stem/shoot.
What is everything but the roots?
What is bark made of?
Dead cells.
Two main types of roots.
What are Taproots and Fibrous roots?
Main purpose of the rootcap.
What is to protect the seed?
What is special about projectile roots? Give one example.
Projectile roots grow mostly above ground, they are usually found in swamps.
Examples: Mangrove, banyan tree, screw pine, etc.
The difference between aerial and subterranean roots.
What is: aerial stems are above ground and subterranean stems are below ground?
Where does the cambium grow?
In between the center of the plant and the outside.
Meaning of a root being adventitious.
What is adventurous?
Purpose of zone of cell elongation.
What is the place where roots grow the most?
What makes parasitic roots special? Give one example.
Parasitic roots will only grow on another plant using them as a host.
Examples: Mistletoe, dodder, witchweeds, etc.
The differnece between herbaceous and woody.
Herbacious: break easy, only alive for one season, green.
Woody: thick, last a long time, stay for multiple seasons.
What is the purpose of heartwood?
To support the plant and determine age.
The difference between Fibrous roots and Taproots.
What is: Taproots have one main root with baby roots steming off of them, Fibrous roots have many roots spread out all over?
The purpose of the zone of cell division.
What is to make the cells?
The chemical in aerial roots.
What is chloraphyl?
What is special about rhysome shoots?
They grow horizontal.
What does the xylem do?
Transports water through the plant.
The word to describe roots sensitivity to gravity.
What is Geotropism?
The purpose of the zone of cell maturation.
What is to distribute cells to where they are needed/assigning cells jobs?
What is special about parasitic root caps?
The root caps suction onto their host plant and they do not secrete the liquid that other root caps do.
Two examples of types of subterranean shoots/stems.
Examples: bulb, tuber, corm, rhiysome.
What does the phloem do?
Transports nutrients/food through the plant.
