|
Cell membrane |
Thin, flexible barrier around a cell; regulates what enters and leaves the cell |
|
|
Chloroplast |
Organelle found in cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy |
|
|
Cell wall |
Strong supporting layer around the cell membrane in plants, algae, and some bacteria |
|
|
Cytoplasm |
Material inside the cell membrane- not including the nucleus |
|
|
Endoplasmic reticulum |
Internal membrane system in cells in which lipid components of the cell membrane are assembled and some proteins are modified |
|
|
Golgi apparatus |
Stack of membranes in the cell that modifies, sorts, and packages proteins from the endoplasmic reticulum |
|
|
Lysosomes |
Cell organelle filled with enzymes needed to break down certain materials in the cell |
|
|
Mitochondria |
Cell organelle that converts the chemical energy stored in food into compounds that are more convenient for the cell to use |
|
|
Nuclear envelope |
Layer of two membranes that surrounds the nucleus of a cell |
|
|
Ribosomes |
Small partial on the cell on which proteins are assembled; made of RNA and proteins |
|
|
Vacuole |
Cell organelle that stores materials such as water, salts, proteins, and carbohydrates |
|
|
Cell |
Collection of living matter enclosed by a barrier that separates the cell from its surroundings; basic unit of all forms of life |
|
|
Cell theory |
Idea that all living things are composed of cells, cells are the basic unit of structure and function in living things, and new cells are produced from existing cells |
|
|
Chromosomes |
Thread-like structure within the nucleus containing the genetic information that is passed from one generation to the next |
|
|
Centrioles |
One of two tiny structures located in the cytoplasm of animal cells located near the nuclear envelope |
|
|
Chromatin |
Granular material visible within the nucleus; consists of DNA tightly woven around proteins |
|
|
Cytoskeleton |
Network of protein filaments within some cells that helps the cell maintain is shape and is involved in many forms of cell movement |
|
|
Eukaryote |
Organisms who's cells contain a nuclei |
|
|
Nucleolus |
The center of the atom which contains the protons and neurons; in cells, structure that contains the cells genetic material (DNA) and controls the cells activities |
|
|
Organelle |
Specialized structure that performs important cellular functions within the eukaryote cell |
|
|
Prokaryote |
Unicellular organism without a nucleus |
|
|
Lipid bilayer |
Doubled layered sheet that forms the core of nearly all cell membranes |
