Journal 4

• What are the three parts of the cell theory? Who are the scientists that developed the cell theory?

• By the way-have you started your project yet???????

Describe organelles involved in energy transformation.

• Energy transformation is the change from one form of energy into another (the making and breaking down of food for energy)

• Energy transformations involve photosynthesis and cellular respiration.

• MITOCHONDRIA: “powerhouse” of cell

•Releases energy from food molecules

•Found in both animal and plant cells

•A cell that needs more energy have more mitochondria

•Ex: muscles, growing cells, areas of repair

• CHLOROPLASTS:

•Found in plant cells

•Contain pigment called chlorophyll

•Allows plants to go through photosynthesis

Describe structures involved in support and locomotion.

•CYTOSKELETON:

•Tiny rods that crisscross cell

•Forms framework to help maintain shape

•CILIA:

•Hairlike projections that move in waves

•FLAGELLA:

•Long tail-like projection that moves in whiplike motion
