How energy from the sun gives you energy to run This is the sun. It is really hot and has a lot of energy. You can see the energy – the sun is bright, and you can feel the energy – the sun is hot. But does it make you full when you are hungry?

How energy from the sun gives you energy to run this a piece of energy, the sun makes lots of them

How energy from the sun gives you energy to run Some of the energy is transferred into leaves of plants.

How energy from the sun gives you energy to run When the leaf gets energy from the sun, its cells capture the energy andtrap it into the form of a sugar called glucose.

How energy from the sun gives you energy to run The leaf cells need water and carbon dioxide to help them trap the suns energy, and poop out oxygen.

How energy from the sun gives you energy to run The plants uses some of this trapped energy right away to power its life processes. And the plant stores some of this glucose to use later (maybe when the sun is not shining?) The plant also converts some of its glucose into more complex sugars for cell walls and other plant parts.

How energy from the sun gives you energy to run This process of capturing the suns energy and converting it to glucose sugars is called… PHOTOSYNTHESIS photosynthesis happens in the chloroplasts of plant cells.

Check your Knowledge 1.What is photosynthesis? 2.What does photosynthesis need? 3.What is the main product of photosynthesis? 4.What does photosynthesis produce as waste? 5.In what organelle does photosynthesis occur?

How energy from the sun gives you energy to run This is Bob. Bob loves to eat salad.

How energy from the sun gives you energy to run The salad is filled with energy from the sun.

How energy from the sun gives you energy to run The energy from the sun that is in the salad that Bob eats travels through his digestive system… …and into Bobs blood stream…

How energy from the sun gives you energy to run … and diffuses into the cells in Bobs muscles

How energy from the sun gives you energy to run Now Bobs muscle cells have to find a way to release the trapped sun energy, so they can use the energy to power Bob. Bobs muscle cell

How energy from the sun gives you energy to run So they send the glucose to the cells mitochondria – the powerhouse of the cell. Bobs muscle cell Mitochondria in Bobs muscle cell

How energy from the sun gives you energy to run The mitochondria break down the glucose molecule to release the trapped suns energy, to give power to Bobs cell. Bobs muscle cell Mitochondria in Bobs muscle cell

How energy from the sun gives you energy to run The mitochondria needs oxygen to help it release this energy And it poops out carbon dioxide and water Bobs muscle cell Mitochondria in Bobs muscle cell

How energy from the sun gives you energy to run See Bob run….. On energy from the sun

How energy from the sun gives you energy to run This process of releasing energy from glucose is called …. ….wait for it…. CELLULAR RESPIRATION

How energy from the sun gives you energy to run We call this released energy ATP. Its actually the name of a molecule, called… …are you ready for this?... …Adenosine TriPhosphate

Check your Knowledge 1.What is CELLULAR RESPIRATION? 2.What is the main point of cellular respiration? 3.What does cellular respiration need? 4.What does cellular respiration give off as waste? 5.What organelle does cellular respiration happen in? 6.What is the energy molecule created during cellular respiration called?
