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

Groups of thylakoids
