Pigments
Chlorophyll is found in __ of cells
Chloroplasts
Chloroplasts contain stacks of membranes known as ___
Grana
Each granum consists of oval shaped ___ ____
thylakoid membranes
_____ is responsible for the green color of plants
Chlorophyll
Excess glucose produces ___ for transport or stored as ___ ____
sucrose : starch polymers
Cell respiration transforms the potential energy of glucose into ___
ATP
What leaf structure are we studying
Mesophyll cell
Epidermis Location
Outer layer of cells in surface of leaf
Epidermis Function
Protects the Leaf
Mesophyll Cells Location
Upper and Lower Epidermis
Mesophyll Cells Function
Conducts Photosynthesis
Stomata Location
Small openings in Epidermis
Stomata Function
Regulate Gas Exchange, controls water loss
Vein Location
Runs through mesophyll layers
Vein Function
Transports waste and sugars
___ is the movement of the cytoplasm caused by convection currents
Cyclosis
Cell Wall Function
Provides structural support and protects cell shape
Chloroplast
Conducts photosynthesis by capturing sunlight
Central Vacuole
Stores water, nutrients. and waste
Nucleus
Contains Genetic Material
Mitochondria
Generates ATP through cellular respiration
__ are openings in the lower epidermal layer of the leaf
Stomata
____ are hair likes structures that prevent dehydration
Trichomes
Green colors in plant cells are due to the ____ a and b
chlorophyll
yellow, orange, and bright red colors are produced by ___
carotenoids
Do plants contain mitochondria ?
Yes dumbass
Carotenoids include Beta Carotene and Xanthophyll, anthocyanins are ___, ____, ____ , ___ pigments found in ___ ____
blue, violet, purple, dark red : central vacuole
Yellow leaves have more ___ than green leaves
starch
Why do discs float to the top as photosynthesis occurs
Oxygen is produced, leaf disc rises to the surface
