Autotrophs

Organisms such as plants that make their own food

Heterotrophs

Organisms that cannot make their own food, such as humans

Cellular Respiration

A chemical process that uses oxygen to convert the chemical energy stored in organic molecules into another form of chemical energy, ATP

Photosynthesis

Plants use the sun's energy to convert water and carbon dioxide into sugars

Inputs - Outputs (Photosynthesis)

CO2 + H2O - C6H12O6 + O2

Inputs - Outputs (Cellular Respiration)

C6H12O6 + O2 - ATP + H2O + CO2

Energy

Heat transfer

Homeostasis

Maintaining a constant temperature

Chloroplast

The site of Photosynthesis

Thylakoid

Contains Chlorophyil

Stages of Photosynthesis

1. Light Reaction
2. Calvin Cycle

NADPH

High-energized molecule made to power Photosynthesis

Mesophyll

The inner layer of tissue of a leaf that contains most of the Choroplasts

Stomata

Tiny pores in the surface of the leaf where CO2 goes in and O2 goes out

Veins

Carry water from roots to the leaf, delivers organics to parts of the leaf

Epidermis

Outside of the leaf, one cell thick

Guard Cells

Moniters what enters and leaves the epidermis

Cuticle

The area outside of the epidermis

Aerobic Process

Needs oxygen
