CELL
|
The basic unit of structure and function in living things.
|
|
|
CELL MEMBRANE
|
A cell structure that controls which substances that can enter or leave the cell. It protects the cell.
|
|
|
CELL THEORY
|
All living things are made up of cells.
Cells are the basic unit of structure and function in living things All cells are produced from other cells. |
|
|
CELL WALL
|
A rigid layer of material that surrounds the
cells of plants and provides support. |
|
|
CHROMATIN
|
Contains the genetic material, the instructions that direct the functions of the cell.
|
|
|
MITOCHONDRIA
|
The powerhouses of the cell -- they produce the energy the cell needs. They are in animal and plant cells
|
|
|
ORGANELLES
|
Different parts of the cell that produce energy, build and transport needed materials and store and recycle wastes
|
|
|
NUCLEUS
|
The cell's control center -- directs all of the cells activities.
|
|
|
CYTOPLASM
|
Regiion between the cell membrane and the nucleus which is filled with think, gel-like fluid.
|
|
|
ENDOPLASMIC RETICULUM
|
Passageways that carry proteins and other materials from one part of the cell to the other.
|
|
|
RIBOSOMES
|
Small grain-like bodies that produce proteins.
|
|
|
GOLGI BODIES
|
Receive proteins and other materials from the endoplasmic reticulum, package them and distribute them to the other parts of the cell.
|
|
|
VACUOLES
|
Sacs that are storage areas of the cell. Plants usually have one large one. Animal cells have small ones or none at all.
|
|
|
LYSOSOMES
|
Small round structures that contain chemicals to break down large food particles into smaller ones. More common in animal cells than in plant cells.
|
|
|
MICROSCOPE
|
An instrument that makes small objects look larger.
|
|
|
COMPOUND MICROSCOPE
|
A light microscope that has more than one lens.
|
|
|
MAGNIFICATION
|
Ability to make things look larger than they are by bending the light that passes through a lens.
|
|
|
CONVEX LENS
|
A lens with a curved shape.
|
|
|
RESOLUTION
|
The ability of clearly see the individual parts of an object.
|
|
|
NUCLEAR MEMBRANE
|
The membrane that protects the nucleus.
|
|
|
CHLOROPLAST
|
A structure in plant cells that converts the sun's rays into energy. It is usually green in color.
|
|
|
NUCLEOLUS
|
A structure that makes ribosomes. It is inside the cell's nucleus
