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
A rigid supporting layer that surrounds the cells 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. 2. The central core of an atom which contains protons and neutrons. 3. The solid inner core of a comet
Organelle
A tiny cell structure that carries out a specific function within the cell
Ribosomes
An organelle that forms a maze of passageways in which proteins and other materials are carried from one part of the cell to another
Cytoplasm
The thick fluid region of a cell located inside the cell membrane (in prokaryotes) or between the cell membrane and nucleus (in eukaryotes)
Mitochondria
Rod-shaped organelles that convert energy in food molecules to energy the cell can use to carry out its functions
Nuclear envelope
The outside covering of the nucleus with has pores which allow materials to pass in and out
Nucleolus
Where ribosomes are made
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
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
Lysosome
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
