DNA A chemical compound that stores information
Catalyst Substance that changes the rate of a chemical reaction or allows a chemical reaction to occur at a lower than normal temperature.
Nucleus Functions the genetic control of the cell, and contains the chromosomes for a cell.
Chromosomes Composed completely of DNA or deoxyribonucleic acid.
Mitochondria The powerhouse of the cell, the site of cellular respiration, a process at which supplies the cell with energy.
chloroplasts found only in plant cells; contains green pigment and chlorophyll
Lysosomes Contain chemicals called enzymes necassary for digesting certain materials in the cell
Vacuoles For the storing of materials in the cell such as: water,salts,proteins, and more.
Ribosomes Protein synthesis, located on rough ER and also on cytoplasm
Endoplasmic Reticulum Complex extensive network that transports materials throughout the inside of a cell.
Golgi apparatus Modifies, collects, packages & distributes molecules in and out of the cell.
Cilia Short hair like projections responsible for the movement of some animal's cells bacteria or protists
Cell membrane Phospholipid bilayer that encloses the cell ®ulates passage of materials between the cell and its environment; also aids in the protection and support of the cell as well
Nuclear membrane Membrane that surrounds the nucleus of the cell
cell wall Not found in animal cells. Surrounds the cell membrane for protection and support in plant cells.
