Functions
Leaves trap light energy for ___________
What is photosynthesis
Edges of the leaf
What is margins
A single leaf arising from the plant stem
What is simple leaf
______ leaves catch more light energy
What is wider or larger
83% of plants use this type of photosynthesis.
What is C3 photosynthesis
Leaves produce sugar from __________ and __________
What is water and carbon dioxide
What is the wide portion of the leaf where photosynthesis occurs?
What is Leaf blade
Two or more leaves arising from a common point on the stem
What is a compound leaf
The openings in a leaf called stomata regulate this.
What is gas exchange
What happens to the gaurd cells of most leaves at night?
What is close.
What is the slender leave stock which supports the blade, attaching it to the stem of the plant?
What is Petiole
What is the vein
Most of the photosynthesis that occurs in a leaf is in this layer
What is the pallisade mesophyl layer
Plants that grow in hot environments use this type of photosynthesis which utilizes bundle sheath cells and makes a 4 carbon molecule
What C4 photosynthesis
Which gas to leaves produce during photosynthesis?
What is O2
The outermost layer of the leaf
What is cuticle and/or epidermis
The apex of the leaf is found where?
What is the tip
True/False
Leaves in a desert environment have more stomata for better gas exchange because the air is hot.
What is false.
They have less to limit water loss.
True or false?
Cacti needles are specialized leaves.
What is true
What gases are exchanged by the leave (3 of them)?
What is O2, CO2 and H2O vapor
Waxy layer on the outside of the leaf to help prevent excess water loss.
What is the cuticle
A leaf that has a rough edge has this type of margin.
What is serrated
The organelle that performs the light reaction of photosynthesis.
What the chloroplasts
If a plant grows in desert climate and does its photosynthesis at night, we call them this
