The ability to do work. Energy can take a wide variety of forms - light energy, electrical energy, heat energy, sound energy, mechanical energy, chemical energy, nuclear or atomic energy.

A group of photosynthetic bacteria containing a blue photosynthetic pigment

A term used to describe a large, diverse group of eukaryotic, photosynthetic organisms, They are usually aquatic, and can be unicellular or multicellular.

A single-celled algae

The organelle in which photosynthesis occurs.

A green pigment that captures light energy for photosynthesis

The opening in a leaf or stem of a plant that enables the gas exchange to occur

The process by which plants release water vapor into the air through stomata; also release of water into the air by other organisms

The process by which cells use oxygen to produce energy from food

The organelle where cellular respiration occurs

The molecules that cells use for energy

A substance made up of molecules that consist of 1 carbon and 2 oxygen atoms

A substance made up of molecules that consist of 1 oxygen atom and 2 hydrogen atoms

An element is usually found in the form of two oxygen atoms bonded together

Organisms that make their own food for energy from non-living substances in their environment

Organisms that can't make their own food and so must get energy by eating plants and animals to survive.

A simple sugar.

Energy from a light source, such as the sun

The energy released when you break chemical bonds

Carbon dioxide + _______ + Light Energy = photosynthesis

Cellular respiration is the opposite of photosynthesis

6CO2 + 6H2O + Sunlight =C6H12O6 + 02

C6H12O6 + 6O2 = 6CO2 + 6H2O + ATP
