Cells Unit

2. Eukaryotic Cells

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.
