Inside a Cell MISS KING’S CLASS Cell Structure Each kind of cell structure has a different function within a cell What structures does a plant cell have that an animal cell doesn’t? Cell wall Chloroplasts Central vacuole Cell Wall and Cell Membrane Cell wall—the rigid layer that surrounds the cells of PLANT cells. What does it do? Helps support and protect the cell. Cell membrane—controls which substances pass into and out of a cell. Found in both plant and animal cells The Nucleus Nucleus—acts as a cell’s control center, directing all the cell’s activities. It is the largest of many cell structures (called organelles). Chromatin are thin strands of material that fill the nucleus Contains all the information for directing a cell’s functions Nucleolus—where ribosomes are made Ribosomes—small grain-shaped organelles that produce proteins. Why are proteins important for the cell? Organelles in the Cytoplasm Most of the cell consists of a thick, clear, gel-like fluid called cytoplasm. Mitochondria—rod-shaped structures that are nicknamed the “powerhouse” of a cell What do they do? They convert energy stored in food to energy the cell can use Endoplasmic reticulum—(ER) is an organelle with a network of membranes that produces many substances. Look closely at the picture in your book… what dots this structure? Ribosomes dot some parts of the ER Helps ribosomes make their protein Organelles in the Cytoplasm Golgi apparatus—receives proteins and other newly formed materials from the ER, packages them, and distributes them to other parts of the cell. What job does this remind you of? Similar to the postal service Vacuole—stores water, food, or other materials needed by the cell. Do animal cells have these? Yes! They have much smaller vacuoles compared to a plant cell, though. Organelles in the Cytoplasm Chloroplasts—capture energy from sunlight and changes it into a form of energy cells can use in making food. What pigment do they contain? Contain chlorophyll Lysosomes—contain substances that break down large food particles into smaller ones Also break down old cell parts What job does this remind you of? Similar to our garbage disposal system. Do Now Brainstorm ways in which a cell is like a school with your groups This will be an in-class project!
