Term | Definition |
---|---|
Organelles | Tiny structures within the cytoplasm that are specialized to carry out certain functions |
Mitochondrion | An organelle that provides the cell with energy through a process known as respiration |
Ribosome | Small organelles that are attached to endoplasmic reticulum and responsible for putting together proteins |
Endoplasmic Reticulum | A series of canal-like folded membranes that helps to carry material through the cytoplasm; can be rough or smooth; rough ER has ribosomes attached |
Golgi Apparatus | An organelle in which proteins are stored; some of these proteins are put into packages called vesicles which can be carried to the surface of the cell and released |
Lysosomes | An organelle that breaks down large molecules within the cytoplasm and destroys damaged or worn-out cells |
Nucleus | The cell structure in plant and animal cells that acts as the control centre and directs all of the cells activities |
Chromosomes | The parts of the cell that contain genetic information |
Cell Membrane | The cell structure in plant and animal cells that covers the entire cell and acts as a gatekeeper by controlling the movement of materials into and out of the cell |
Cytoplasm | The fluid area of the cell in which nutrients are absorbed, transported, and processed, and wastes are stored until proper disposal can be carried out. |
Cell Wall | The plant cell structure that protects and supports the plant cell |
Vacuole | A fluid-filled space in plant and animal cells that can hold food and water |
Chloroplasts | The plant cell structure that contains many molecules of a green pigment called chlorophyll that helps plants use energy from the sun to make their own food |
