Term | Definition |
---|---|
Prokaryotic Cells | Do not have genetic material or structures surrounded by membranes Few internal structures One-celled organismssuch as Bacteria |
Eukaryotic Cells | Genetic material is in a structure enclosed by its own membrane Contain organelles surrounded by membranes Most living organisms |
Nucleus | Control Center of the Cell; controls the functions within the cell and contains the genetic material |
Chromosomes | Physical structures in a cell that contain the cell’s genetic material which provides instructions for the cell’s functions |
Cell Membrane | semi-permeable membrane that forms the boundary of the cell and controls what comes in and goes out of the cell |
Cell Wall | Provides additional structure and support for cells |
Chloroplast | found in cells that contain chlorophyll and uses light energy to make food for the cell |
Cytoplasm | Gel-like substance that nutrients move through in the cell and also acts as a shock absorber |
Mitochondria | Breaks down material and releases energy into the cell Powerhouse |
Endoplasmic Reticulum | Helps move substances within cells Network of interconnected membranes |
Rough Endoplasmic Reticulum | Ribosomes attached to surface Manufacture proteins Not all ribosomes attached to rough ER May modify proteins from ribosomes |
Smooth Endoplasmic Reticulum | No attached ribosomes Has enzymes that help build molecules Carbohydrates Lipids |
Golgi Apparatus | Involved in synthesis of plant cell wall Packaging & shipping station of cell |
Lysosomes | clean up waste products like lysol |
Vacuoles | Membrane bound storage sacs More common in plants than animals Contents: Water Food wastes |
