Science Test 2.1 and 2.2: Photosynthesis/Cellular Respiration

Photosynthesis equation

LIGHT ENERGY + 6CO2 + 6H2O -----> C6H12O6 + 6CO2

(carbon (water) (glucose) (oxygen)

dioxide)

Cellular respiration equation

C6H12O6 + 6O2 -----> 6CO2 + 6H2O + ENERGY

(glucose) (oxygen) (carbon (water)

dioxide)

How is ATP produced?

ATP is produced when cells break down glucose during cellular respiration, mainly in the mitochondria.

Why do we see plants as green?

We see plants as green because in the chloroplast there is a pigment called chlorophyll that absorbs every color but reflects the color green from sunlight, making plants look green.

Mitochondria

Rod-shaped organelles that are nicknamed the "powerhouses" of the cell. They convert energy stored in food to energy the cell can use to live and funtion.

Chloroplast

A small green structure that captures energy from sunlight and changes it to a form of energy cells can use in making food.

ATP

A molecule that stores and supplies energy for cells.

Autotroph

An organism that makes its own food.

Cellular respiration

The process by which cells obtain energy from energy using oxygen.

Photosynthesis

The process by which a cell captures energy in sunlight and uses it to make food.

Energy

What comes from sunlight and is what plants use to make glucose.

Producers

Organisms that can make their own food. They capture energy in sunlight and turn that energy into glucose (sugar).

Consumers

Organisms that don't make their own food so they have to obtain energy some other way.

Glucose

A sugar that plants make when going through photosynthesis. Glucose is what plants "eat".

Heterotroph

An organism that can't make its own food.

Food

A sugar called glucose. Glucose is made when plants go through photosynthesis and make food.

Fermentation

An energy-releasing process that doesn't require oxygen.

Lactic acid

It is a product of lactic acid fermentation. Your cells make energy by breaking down glucose without using oxygen. When lactic acid builds up, you feel it as a burning sensation.
