Cell Theory and Structure

Question Answer
The theory that the cell is the fundamental structural and functional unit of living matter. Cell Theory
the thin membrane that surrounds the cytoplasm of a cell; regulates the passage of materials in and out of the cell. Cell Membrane
Surrounds a cell membrane of a plant cell to give structure and protection to the cell.(provides support). Cell Wall
The green organelle in plant cells that converts light energy into chemical energy. Chloroplast
Found in the nucleus and made of DNA, these contain the genetic information of the cell. Chromosomes
Hair-like structures that extend from the surface of the cell to help with movement. Cilia
The jellylike material that fills the cell, and in eukaryotic cells, surrounds the nucleus. Cytoplasm
Long, whip like structure that allows a cell to move. Flagellum
Holds waste materials from the cell; breaks down food, worn out pieces of cells, and other wastes. Generally found in animal cells. Lysosomes
Functions in energy production, the powerhouse of the cell. Mitochondrion
Found in eukaryotic cells; contains genetic material (DNA) responsible for controlling the activities of the cell. Nucleus
Stores water and food in both plant and animal cells (larger in plants). Vacuole
How the parts are put together. Structures
Tube-like structures that exist in pairs in animal cells; guide the chromosomes during cell division. Centriole
Building site for the proteins of the cell Ribosomes
Clear tubular passageways studded with ribosomes; for transportation of materials throughout the cell . Endoplasmic Reticulum- Rough
clear tubular passageways (free of ribosomes); for transportation of materials throughout the cell. Endoplasmic Reticulum- Smooth
stores packages and ships cellular materials. Golgi Bodies
