•The cellular machinery requires a coninuous energy supply to do all the work of life.

•The two types of cellular power stations are organelles called chloroplasts & mitochondria.

•One harnesses light energy from the sun, and the other "unpacks" this captured energy into smaller packets that are useful for powering cellular work.

• The cellular machinery requires a continuous energy supply to do all the work of life.

• The two types of cellular power stations are organelles called chloroplasts & mitochondria.

• One harnesses light energy from the sun, and the other "unpacks" this captured energy into smaller packets that are useful for powering cellular work.

Cellular Respiration

• The process by which cells make ATP

Photosynthesis

• Process by which plants and some other organisms use light energy to convert water and carbon dioxide into oxygen and CHO

ChloroplastsChloroplasts

• Plants and algae (plant-like protists) harness light energy thru photosynthesis

• Found only in Eukarya autotrophs/producers

• Double membrane

• Inner membrane has many folds .


• Inner membrane also has many enzymes for cellular respiration.

• MATRIX-Inner fluid filled space


•Two membranes

•Inner membrane is convoluted with myriad folds .

•Inner membrane also has many embedded enzymes for cellular respiration.

•Inner fluid filled space (matrix)

Plant cells have both mitochondria and chloroplasts
