Objective: 1) Identify cell structures responsible for energy and locomotion. 2) Determine the function of plant cell organelles. Energy Organelles of the Cell Mitochondria 1) Often termed the “Battery of the Cell” 2) Takes in Glucose to create the energy molecule ATP. *The more active a cell is, the more batteries or mitochondria it will have. *Interesting mitochondria has its own DNA, separate from the DNA found in the nucleus. Organelles of Locomotion 1.Flagella: whip-like tail. Some cells have up to 2 flagella. 2.Cilia: numerous hair-like projections that move synchronously to allow the cell to move (similar to hundreds of boat oars moving at the same time). The Plant Cell Characteristics Cell Wall: Supports, protects, and connects to other plant cells. Made up of cellulose. Chloroplasts 1) Use light energy to make sugars (photosynthesis). These sugars can be linked together to make other organic compounds. 2) Chloroplasts and mitochondria provide energy for the plant cell Chloroplast: sunlight glucose Mitochondria: glucose ATP (fuel) Central Vacuole: large vacuole that stores water. Note: animal cells have vacuoles as well. Vacuoles are used to store water and nutrients. Only plants have the large contractile vacuole. 1
