Cells Terms

Science Stuff

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.
