Prokaryotic cell
Cell lacking a nucleus and most other organelles
Does not have nucleus or other part
Eukaryotic cell
Cell with a nucleus ( surrounded by its own membrane ) and other internal organelles
Unicellular
Single cell
Multicellular
Many cells
Organelle
Part of a cell with a specific function
Nucleus
In an atom, the central core that contains protons and neutrons, in a cell, the part that houses the cell’s genetic material in the form of DNA
Lysosome
Membrane-bound sac containing digestive enzymes that can break down proteins, nuclei can acids, and polysaccharide
Cell
The basic unit of living matter; separated from its environment by a plasma membrane
Ribosome
Cluster of proteins and nuclei can acids that constructs proteins in a cell
What are 3 parts of the cell theory
Generalization that all living things are composed of cells, and that cells are the basic unit of structure and function in living things
Endoplasmic reticulum
Network of membranes within a cells cytoplasm that produce a variety of molecules
Vacuole
Membrane-bound sac that buds from the endoplasmic reticulum or the Golgi apparatus
Nucleolus
Ball like mass of fiber and granules in a cell nucleus
Mitochondrial
Cellular organelles where cellular respiration occurs
Energy
Cell wall
Strong wall outside a plant cells plasma membrane that protects the cell and maintains its shape
Chloroplasts
Organelle found in some plant cells and certain unicellular organisms where photosynthesis takes place
Golgi apparatus
Cellular organelle that modifies, stores, and routes cell products
Cytoplasm
Region of a cell between the nucleus and the plasma membrane
What is the difference between a plant and animal cell?
Plant- has cell wall and corplast
Animal- no cell wall and no corplast
