Photosynthesis

Autotrophic NutritionLight Energy Chemical Energy

Equation:

Parts of the Leaf

Upper Epidermis / Cuticle

• Prevents water loss

Palisade Layer

• Photosynthesis• Makes / Manufactures food (glucose)

Vein

• TRANSPORTS food and water• Phloem: Food• Xylem: Water

Stomate

• Gas Exchange

Guard Cell

• Controls the size of the opening

Cellular Respiration

• Used for ENERGY (ATP)• Take place in the MITOCHONDRIA• Used by Autotrophs and Heterotroph

Equation:

Aerobic Respiration

• WITH Oxygen• 36 ATP produced• Mitochondria

Anaerobic Respiration

• WITHOUT Oxygen• 2 ATP Produced• Alcohol Fermentation (Yeast)• Lactic Acid (Muscle Cramps)• Cytoplasm

Transport

• Movement of Molecules

Passive Transport / Diffusion / Osmosis• Movement from HIGH to LOW• Does NOT use ATP (Energy)• Osmosis: Diffusion of WATER from high to low

High

Low

Active Transport

• Movement from LOW to HIGH• Uses ATP (Energy)
