Plants Flashcards
Dicot vs Monocot?
Monocot - one cotyledon - fibrous roots - scattered vascular tubes - parallel veins (leaf) - flower of 3 petals Dicot - two cotyledon - tap roots - ringed vascular tubes - net-like veins - flower of 4-5 petals
What is a pneumatophore?
(in mangroves and other swamp plants) an aerial root specialized for gaseous exchange.
What is a prop root
Any of the modified roots that arise from the stem of certain plants and provide extra support.
What is a root hair,
each of a large number of elongated microscopic outgrowths from the outer layer of cells in a root, absorbing moisture and nutrients from the soil.
What are the functions of roots?
1) absorption of water and inorganic nutrients,
2) anchoring of the plant body to the ground, and supporting it,
3) storage of food and nutrients,
4) vegetative reproduction and competition with other plants.
What is the function of stomata? Be able to sketch and label a stoma. Where is it located?
A stoma is a small opening in the plant that “breaths” allowing it to absorb oxygen
It is located on the underside of the leaf
why are vascular plants are able to grow much taller than non-vascular plants?
Vascular plants are more complex (xylem for water, phloem for food) and can absorb more water + nutrients
What are the basic parts of a seed
Embryo - the baby plant consists of plumule, radicle, and cotyledon.
Endosperm - a source of stored food (usually starch) used as a supply while the bean sprouts
Seed coat - the outer layer
What is the equation for photosynthesis?
CO2 + H20 –> Sun –> C6H12O6 + O2
