By Sam, Joey, Mikayla, Frankie.
Cell Theory Cells are the basic units of life. Living things are made of one or more cells. All cells come from existing cells.
Cell Membrane and Nucleus Cell membrane- surrounds cells, holding parts together Nucleus- directs all activities that are produced by the cell.
Mitochondria and Vacuole Mitochondria- changes chemical energy of food in a substance that cells can use. Vacuole- contains fluid and is surrounded by a membrane. Stores water and nutrients and digest food.
Cytoplasm and Endoplasmic Reticulum Cytoplasm- material between the nucleus and cell membrane, fluid that contains the organelles. Endoplasmic Reticulum- Serves as a transportation system; makes protein.
Ribosomes and Lysosomes Ribosomes- found in the endoplasmic reticulum; begins the process of making protein Lysosomes- contains powerful chemicals that break down harmful molecules and recycle worn-out cell parts.
Cell Wall and Cell Membrane Cell Wall- surrounds cell membrane, it gives extra support. Cell Membrane- surrounds cell holding parts together.
Nucleus and Mitochondria Nucleus- directs cell activities; is the control center of the cell Mitochondria- converts chemical energy of food into a form that cells can use.
Vacuole and Chloroplasts Vacuole- stores water and nutrients and helps the cell digest food. Chloroplasts- contain chlorophyll which gives plants green color, plants make food when sunlight strikes chlorophyll.
