Anatomy
What are the main parts of a plant
Leaf, Stem, Roots.
What is the function of the plant leaves?
Photosynthesis and gas exchange
Green
What are the primary functions of the roots in a plant?
To absorb water and anchor down the plant.
It produces the plants food (gluclose)
Name 2 different stems
Shoot, twig, branches, canes, and a trunk or bole
What does the stem do? Name 2
connect the roots to the leaves and other parts of the plant. Transports water, minerals, and sugars (food). Some types of stems provide a way for plants to retain nutrients for later.
What is the flat part of the leaf called?
Blade
What part of the plant is responsible for photosynthesis?
The leaves
What are the 2 main classes of plants
Monocot and dicot
What is the function of stomata?
Allowing gas exchange
What does the leaf take in to make food?
Carbon Dioxide
What does taproot systems do?
ekongates downward. becomes central and most imporetant feature. Found on dicotylendons.
What does photosynthisis use?
Carbon Dioxide, Water.
What are the main tissues of the stem
xylem, phloem, and vascular cambium.
What is the role of chlorophyll in plants?
Absorbs sunlight to carry out photosynthesis
What part of the leaf lets out water and oxygen?
The stomata
What are 3 root types?
Fibrous, taproot system, Aerating roots, Haustial roots, Epiphytic roots,
What two things do plants need for photosynthesis?
Sunlight and Carbon Dioxide
What are the five major plant hormones
Auxins, Gibberellins, Cytokinins, Abscisic Acid, Ethylene
What do two of the five hormones in the plant do? (It can be any of the five)
Auxins- master plant growth regulator, and promote shoot and root cell elongation for growth.
Gibberellins- cause cell elongation for shoot growth, fruit maturity, seed germination, and help regulate dormancy
Cytokinins- promote cell division in stems, leaf growth, and bud creation
Abscisic Acid- controls the dormancy of buds and seeds, and inhibits shoot growth. Triggers seeds to go dormant by blocking germination, also triggers buds to go dormant
Ethylene- the only known gaseous plant hormone that freely moves around trees and promotes the dropping of leaves and fruits, and inhibits shoot elongation
Why do leaves change color in the fall?
What is the formula is for photosynthisis?
CO2 + H2O = C6H12O6 + O2
