2. Eukaryotic Cells
Term | Definition |
---|---|
Two types of Eukaryotic Cells | Animal cells and plant cells. |
Cell wall | is a rigid structure that gives support to a cell. Found in plant cells and prokaryotic cells. |
Cell membrane | All cells have a cell membrane. It is a protective barrier that encloses a cell. Where cells have no cell wall, the cell membrane is the outermost layer. Cells that have cell walls, the membrane is right inside the wall. |
Cell membrane | is made up of proteins, lipids, and phospholipids. |
cytoskeleton | a web of proteins in the cytoplasm that helps keep the cell from collapsing. |
Nucleus | a large organelle found in all eukaryotic cells. It contains the cells DNA and genetic material. |
nucleolus | where a cell makes its ribosomes. |
ribosomes | organelles that are made of RNA and protein; the site of protein synthesis |
amino acid | one of about 20 different organic molecules that make up proteins. |
True | All cells have ribosomes. |
Endoplasmic Reticulum | a system of membranes that is found in a cell's cytoplasm and that assists in the production, processing and transport of proteins and in the production of lipids. |
mitochondrion | main power source of the cell where sugar is broken down for energy |
ATP | a substance where energy released from mitochondria is stored. |
Chloroplast | organelles in plants and animals where photosynthesis takes place. |
photosynthesis | process by which plants and algae use sunlight, carbon dioxide, and water to make sugar and oxygen. |
chlorophyll | a green pigment |
Golgi Complex | cell organelle that helps make and package materials to be transported out of the cell |
vesicle | a small cavity or sac that contains materials in a eukaryotic cell. |
Lysosomes | organelles that contain digestive enzymes and responsible for digestion in the cell. They destroy damaged organelles, get rid of wste and protect the cell. |
Vacuole | is a type of lysosome in plant cells. |
