Prokaryote
• The prokaryotes are a group of organisms whose cells lack a cell nucleus.
Eukaryote
• A eukaryote is an organism whose cells contain complex structures enclosed within membranes.
Organelle
• Tiny structures that carry out functions necessary for the cell to stay alive
Nucleus
• Control center of the cell
Ribosome
• small organelles that make proteins
Cytoplasm
• region between the cell membrane and the nucleus
Vacuole
• an organelle that stores food, water, and other materials needed by the cell
Lysosome
• contain substances that break down large food particles into smaller ones
Chloroplast
• A structure in the cells of plants and some other organisms that captures energy from sunlight and uses it to produce food.
Mitochondria
• organelles that convert the chemical energy stored in food into compounds that are more convenient for the cell to use
Cilia and Flagella
Chlorophyll
• Chlorophyll is a green pigment found in cyanobacteria and the chloroplasts of algae and plants.
Cell Wall
• A rigid structure that surrounds the cells of plants and most bacteria
Plasma Membrane
• thin, flexible barrier around a cell; regulates what enters and leaves the cell
Microfilaments/Microtubules• Microfilaments or actin
filaments are the thinnest filaments of the cytoskeleton, a structure found in the cytoplasm of eukaryotic cells.
• Microtubules are a component of the cytoskeleton, found throughout the cytoplasm. These tubular polymers of tubulin can grow as long as 25 micrometres
Golgi Apparatus
• receives proteins and other newly formed materials from the ER, packages them, and distributes them to other parts of the cell or to the outside of the cell
Endoplasmic Reticulum
• network of membranes within a cell's cytoplasm that produces a variety of substances
Chromatin
• contains information for directing a cell's activities
Centrioles
• A centriole is a cylinder shaped cell structure found in most eukaryotic cells, though it is absent in higher plants and most fungi.
