photosynthesis
process by which autotrophs convert sunlight to a usable form of energy; process by which autotrops use sunlight to make high-energy sugars
pigment
molecule that absorbs certain wavelenghts of light and reflects or transmits others
Chlorophyll
Most comont and most important photosynthetic pigment in plants and algae; principal pigment found in plants
Chloroplasts
Organelles that contain cholorphyll
Stroma
Gel like material that surrounds the thylakoids; region outside the thylakoid membranes
Grana
Stacks of disk-shaped structuctures that contain chlorophyll
Photosystems
light-collecting untis of the chloroplast
Plants use energy from snlight to split molecule of____________, releasing oxygen,________, and _________ in the light dependent reactions.
Carbon dioxide
ATP
Hydrogen ions
Starch
Glucose
Most plants store energy in the form of _______, which are long strings of ________ molecules.
Light-dependent reactions
produce oxygen gas and convert ADP to ATP
Cutin
prevents water loss through evaporation
Guard cells
control the opening and closing of the stomata
Lower Epidermis
Protects the inner tissues from injury
Palisades and Spongy Layer
chlorophyll is found here within the chloroplast
Phloem
carries food
Stomata
Let's gases enter and leave the leaf
Stroma
Contains the enzymes neccesary for photosynthesis
Thylakoid
Chlorophyll is found here within the chloroplast
Upper Epidermis
Protects the inners tissues from injury
Vein
Composed of xylem and phloem
Xylem
carries water and minerals
Layers in order
Cutin
Upper Epidermis
Lower Epidermis
Spongy Layers
Guard cells
Stomata (in between guard cels)
Grana Stacks
