Parts Of A Cell Flashcards
Cell membrane
A thin, flexible barrier that surrounds a cell and controls which substances pass into and out of cell
Cell Wall
A rigid supporting layer that surrounds the cells of a plant 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 cells activities
Organelle
A tiny cell structure that carries out a specific function within the cell.
Nuclear envelope
Materials pass in and out of nuclear
Nucleolus
Robisomes are made
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 (in prokaryotes) or between the cell membrane and nucleus (in eukaryotes).
Mithicondria
Rod-shaped organelles that convert energy in food molecules to energy the cell can use to carry out its functions.
E.R.
Endoplasmic reticulum
Organelle with a network of membranes that produces many substances
Carries proteins from one part of the cell to another
Golgi apparatus
An organelle in a cell that receives proteins and other newly formed materials from the endoplasmic reticulum, packages them, and distributes them to other parts of the cell.
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
A cell organelle which contains chemicals that break down large food particles into smaller ones and that can be used by the rest of the cell.
