Term | Definition |
---|---|
Animal Cell | The animal cell is the functional and biological unit of all known living organisms. |
Plant Cell | A plant cell is a cell that is a structural and functional unit of a plant. |
Bacteria Cell | A bacteria cell is unlike animals and plants, bacteria have pili, flagella, and most have a cell capsule. |
Mitochondria | A mitochondria is an organelle found in large numbers in most cells. |
Ribosome | A ribosome is a minute particle consisting of RNA and associated proteins, found in large numbers in the cytoplasm of living cells. |
Vesicle | A vesicle is a fluid- or air-filled cavity or sac, in particular. |
Nucleus | A nucleus is a membrane bound structure that contains the cell's hereditary information and controls the cell's growth and reproduction. |
Chloroplast | Chloroplast is plastid that contains chlorophyll and in which photosynthesis takes place. |
Golgi Apparatus | A major organelle in most Eukaryota cells is the structure of membrane-bound sacs called the Golgi apparatus |
Cell Membrane | A Cell Membrane is the semipermeable membrane surrounding the cytoplasm of a cell. |
Cell Wall | A cell wall is a rigid layer of polysaccharides lying outside the plasma membrane of the cells of plants, fungi, and bacteria. |
Cytoskeleton | A network of threadlike proteins joined together that gives a cell it's shape and helps it move. |
Smooth Endoplasmic reticulum | Smooth Endoplasmic Reticulum is an organelle of cells in eukaryotic organisms that forms an interconnected network of membrane vesicles |
Rough Endoplasmic reticulum | Parts of the endoplasmic recticulum to which ribosomes are attached on the cytoplasmic side. |
Lysosome | One body of the minute bodies occurring in many types of cells, containing various hydrologic enzymes and normally involved in the process of localized intracellur digestion. |
Centriole | Ether two of the cylindrical organelles located in the centre some and containing nine triplets of microtubules arrayed around their edges. |
DNA | DNA is a self-replicating material present in nearly all living organisms as the main constituent of chromosomes. |
Flagellum | A long whip like structure on many bacteria. |
Capsule | Capsule - Found in some bacterial cells, this additional outer covering protects the cell when it is engulfed by other organisms, assists in retaining moisture. |
Prokaryotic Cells | A unicellular rag ism lacking a true nucleus and nuclear membrane. |
Eukrayotic Cells | A single celled membrane or multicellular organism who's cell contains a distant membrane nucleus. |
Organelles | A cell structure in which the functions are carried out to ensure the cells survival. |
Unicellular | A living thing that is made up of only one cell. |
Multicellular | A living thing that is made up of many cells. |
Define the cell theory | The cell theory is a theory saying that cells make up a structure. |
Nuclear Membrane | Nuclear Membrane is the double lipid bilayer membrane which surrounds the genetic material and nucleolus in eukaryotic cells. |
Nuclear Envelope | A nuclear envelope is the double lipid bilayer membrane which surrounds the genetic material and nucleolus in eukaryotic cells. |
Nucleolus | A nucleolus is a small dense spherical structure in the nucleus of a cell during inter phase. |
Central vacuole | The primary function of the central vacuole in plant cells is to maintain the turgor of the cell. |
