Parts Of 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 supporter layer that surrounds the cells of plants and some other organism.
Nucleus
In cells, a large oval organelle that contains the cells genetic materiel 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
¿?
Nucleolus
The nucleolus is were the ribosomes is made.
Ribosomes
A small grain-shaped organelle in the cytoplasm of a cell that produces proteins.
Cytoplasm
The cytoplasm fills the region between the cell membrane and the nucleus.
Mitochondria
Rod-shaped organelles that convert energy in food molecules to energy the cell can use to carry out its functions.
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.
Lysosomes
Lysosomes contain substances that break down large food particles into smaller ones.
