Parts of a Cell Flashcards
Cell Membrane
A thin, flexible barrier that surrounds a cell and controls which substances pass into and out of a cell.
Cell Wall
Rigid supporting layer that surrounds the cell of plants and some other organisms.
Nucleus
In cells, a large oval organelle that contains the cell’s genetic material in the form of DNA and controls many of the cell’s activities
Organelle
A tiny cell structure that carries out a specific function within the cell.
Nuclear Envelope
It protects the nucleus, and send out messengers to send information.
Nucleolus
??
Ribosomes
A small grain-shaped organelle in the cytoplasm of a cell that produces proteins.
Cytoplasm
The thick fluid region of a cell located inside the cell membrane or between the cell membrane and nucleus.
Mitochondria
Rod-shaped organelles that convert energy in food molecules to energy the cell can use to carry out its functions.
Golgi Apparatus
An organism’s genetic makeup, or allele combinations.
Vacuole
A sac-like organelle that stores water, food, and other materials.
Chloroplast
An organelle in the cells of plants and some other organisms that captures energy from sunlight and changes it to an energy form that cells can use in making food.
Lysosomes
Contain substance that break down large food particles into smaller ones, also break down old cell parts and release the substances so they can be used agein.
Endoplasmic Reticulum
An organelle that forms a maze of passageways in which proteins and other materials are carried from one part of the cell to another.
