Photosynthesis/Cellular Respiration

By Ricky & Gera

Photosynthesis

• Photosynthesis – is the process that plants cell use to change the energy from sunlight into chemical energy

• Takes place in plant cells that have chloroplast.

• Chloroplast contain chlorophyll, green pigment the traps energy.

Steps

• The plant takes in carbon dioxide from the air and water from soil

• Chlorophyll captures energy from sunlight which is used to change carbon dioxide and water into new products.

• The plant releases most of the oxygen into the air

6H2O + 6CO2 + Light Energy = C6H1206 + 6O2

Cellular Respiration

• Cells use oxygen to release energy stored in sugars such as glucose.

• Takes place in mitochondria.• Both in animal and plant cells

Steps• Starts with glucose and oxygen• Glucose in cytoplasm is broken down into smaller

molecules. Releases small amount of energy. They move into the mitochondria. Also oxygen enters the cell and into the mitochondria. Smaller molecules are broken down even further, hydrogen is released in a way that allows cells to capture energy hydrogen combines with oxygen to make water.

• C6h1206 + 602= chemical energy +6h20+6C02
