BOTH muscle and plant cells need energy to live. –Muscle cells need energy to help you move –plant cells need energy to perform life functions like making food, and cell reproduction. How they get their energy is DIFFERENT! –Plants use the chloroplasts in their cells to make most of their energy –Animals use the mitochondria in their cells to make all of their energy Skeletal muscle cells Plant cells
Animals get energy from: _____________ Plants get energy from: ______________ A major source of energy for most cells is stored in a molecule of sugar called GLUCOSE –Plants use the sun to make glucose –Animals eat glucose
PLANTS – SOURCE OF ENERGY IS SUNLIGHT What is an autotroph?What is an autotroph? What is a heterotroph?What is a heterotroph? Who are the heterotrophs in this picture?Who are the heterotrophs in this picture? Plants make their own food through the process of photosynthesisPlants make their own food through the process of photosynthesis They are known as AUTOTROPHS (grass)They are known as AUTOTROPHS (grass)
PHOTOTSYNTHESIS Process where a plant’s cells change the energy from the sun in to chemical energy. Takes place in cells that have the chloroplasts. Chloroplasts contain chlorophyll: a pigment that traps the energy in the sunlight.
PHOTOSYNTHESIS STARTING MATERIALSTHE PROCESSTHE PRODUCTS Carbon Dioxide (CO 2 )from the air Water from the soil Carbon Dioxide enters through the STOMATA and water enters through the ROOTS and moves upward. They move to the leaf and its chloroplasts. The chlorophyll captures the energy from the sun and its used to change the CO 2 and H 2 O to new products. Oxygen and sugars like GLUCOSE are made. Plant releases oxygen to the air and uses the sugars for energy.

Photosynthesis is Essential for the Air YOU Breathe 21% of the atmosphere is Oxygen, thanks to plants, algae, and some bacteria. The levels of oxygen remain balanced in the atmosphere –Plants makes O 2 for the animals during photosynthesis –Animals make CO 2 for the plants during a process called respiration
