Science - Photosynthesis Quiz Flashcards

Photosynthesis

The process by which plants and other autotrophs capture and use light energy to make food from carbon dioxide and water.

autotroph

An organism that is able to capture energy from sunlight or chemicals and use it to produce its own food.

heterotroph

An organism that cannot make its own food and gets food by consuming other things.

chlorophyll

A green photosynthetic pigment found in the chloroplasts of plants, algae, and some bacteria.

cellular respiration

the process that releases energy by breaking down glucose and other food molecules in the presence of oxygen.

glucose

A common sugar that is found in nature; is the food that plants make during photosynthesis

respiration

moving air in and out of your lungs - breathing

lactic acid

A compound produced during fermentation that causes pain and weakness in human muscles.

plants use water, carbon dioxide, and sunlight to produce oxygen, water and…

glucose

in which organelle does photosynthesis occur?

chloroplast

chlorophyll

what is the source of energy during photosynthesis?

sunlight

stomata

the tiny openings on the underside of a leaf that help plants take in CO2

they are stored at starches for later use

oxygen

a gas produced during photosynthesis

reactants

light energy, carbon dioxide, water

the things needed for photosynthesis to occur

glucose, oxygen

the products of photosynthesis
