Organelle
|
A tiny cell structure that carries out a specific function within the cell.
|
|
Cell Wall
|
A rigid layer of nonliving material that surrounds the cells of plants and some other organisms.
|
|
Cell Membrane
|
A cell structure that controls which substances can enter or leave the cell.
|
|
Nucleus
|
A cell structure that contains nucleic acids, the chemical instructions that direct all the cell's activities.
|
|
Nuclear Envelope
|
The nuclear envelope protects the nucleus, materials pass in and out of the nucleus through pores in the nuclear envelope.
|
|
Ribosome
|
A small grain-like structure in the cytoplasm of a cell where proteins are made.
|
|
Chloroplast
|
A structure in cells of plants and some other organisms that captures energy from sunlight and uses it to produce food.
|
|
Chromatin
|
Chromatin, contain genetic material, the instructions for directing the cell's functions.
|
|
Nucleolus
|
A nucleolus, is where ribosomes are made.
|
|
Lysosome
|
A small, round cell structure containing chemicals that break down large food particles into smaller ones.
|
|
Specialized Cell
|
Nerve cells carry information throughout the human body. Red blood cells carry oxygen. Bone cells produce chemicals that strengthen bone. All are specialized cells.
|
|
Tissue
|
A tissue is a group of similar cells that work together to perform a specific function.
|
|
Organ
|
An organ, such as your brain, is made of different kinds of tissues that function together
|
|
Organ System
|
An organ system is a group of organs that work together to perform a major function.
|
|
Bacterial Cell
|
While a bacterial cell does have a cell wall and a cell membrane, it does not contain a nucleus. The bacterial cell's genetic material, which looks like a thick, tangled string, is found in the cytoplasm.
|
|
Mitochondria
|
Rod-shaped cell structures that convert energy in food molecules to energy the cell can use to carry out its functions.
|
|
Cytoplasm
|
The region between the cell membrane and the nucleus.
|
|
Endoplasmic Reticulum
|
A cell structure that forms a maze of passageways in which proteins and other materials are carried from one part of the cell to another.
|
|
Golgi Body
|
A cell structure 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 inside a cell that acts as a storage area.
