|
Prokaryotic cell |
Small cells without a nucleus, no membrane-bound organelles and are unicellular
|
|
|
Eukaryotic cell
|
A cell that has a “true nucleus” and contains membrane-bound organelles and can be part of a multi-cellular organism
|
|
|
Uni-cellular |
A term that describes organisms like bacteria and some protists that are made of a single cell |
|
|
Multi-cellular
|
A term that describes organisms made of many cells
|
|
|
Nucleus
|
A large structure in the cell that contains the genetic material and controls the cell’s activities
|
|
|
Chromatin
|
Granular material spread throughout the nucleus and made of RNA
|
|
|
Chloroplast
|
An organelle that can take energy from the sun to make energy rich food molecules
|
|
|
Flagella/cilia
|
Whip-like and hair-like structures that aid in movement of some cells
|
|
|
Chromosome
|
Thread-like structures of condensed chromatin that form when a cell is ready to divide. They contain DNA
|
|
|
Nuclear membrane
|
An organelle dotted with tiny pores that regulates materials that can enter and leave the nucleus
|
|
|
Cell membrane
|
A thin flexible barrier that surrounds the cell’s contents and regulates what goes in and out of a cell so that it maintains homeostasis
|
|
|
Cell wall
|
A rigid structure on the outside of the membrane that protects and supports a cell
|
|
|
Cytoplasm
|
The liquid part of a cell that bathes them in nutrients and provides a medium to support them
|
|
|
Organelle
|
Little compartmental organ in the cell with a specific duty
|
|
|
Vacuole
|
An organelle that temporarily stores needed materials like food and water. They also give support to plants
|
|
|
Ribosome
|
Small structures made up of RNA and proteins that are responsible for making proteins
|
|
|
Nucleolus
|
A dense location in the nucleus where ribosomes are assembled
|
|
|
Endoplasmic reticulum (ER)
|
An organelle where parts of the cell membrane (lipids) are made and where some proteins are chemically modified
|
|
|
Golgi apparatus
|
An organelle that packages and stores proteins for transport out of the cell
|
|
|
Lysosome
|
A small organelle containing digestive enzymes that break down food particles and recycle cell parts that are no longer needed
|
|
|
Vesicle
|
An organelle that isolates specific molecules and transports them from the Golgi to the cell membrane
|
|
|
Mitochondria
|
An organelle responsible for releasing energy from stored food molecules to power all cell functions |
