|
Organelle
|
A structure or part that is enclosed within its own membrane inside a cell and has a particular function.
|
|
|
Cell Wall
|
The cell wall is a rigid layer of nonliving material that surrounds the cells of plants and some other organisms. It helps to protect the cell.
|
|
|
Cell Membrance
|
The cell membrance controls what substances come into and out of a cell. Barrier between cell and its environment.
|
|
|
Nuclear Envelope
|
The nuclear envelope protects the protects the chromatin(DNA).
Materials pass in and out through the pores. |
|
|
Nucleolus
|
This structure is where the ribosomes are made.
|
|
|
Chromantin
|
These are strands that hold the instructions for directing the cell's functions. They also contain the DNA. Copies of instructions are called RNA.
|
|
|
Nucleus
|
You can think of the nucleus as the cell's control center, directing all of the cells activities. It contains DNA and RNA.
|
|
|
Cytoplasm
|
The cytoplasm is between the cell membrane and the nucleus. Many cell organelles are found here. Gel-like fluid. Dissolves important chemicals needed for life.
|
|
|
Mitchondria
|
Mitochondria are know as the "power houses" of the cell because they convert energy in food molecules to energy the cell can use to carry out its functions.
Requires oxygen. |
|
|
Endoplastic Reticulum (ER)
|
The rough ER's passageways carry proteins and other materials from one part of the cell to another. Coverred in ribosomes. The smooth ER produces and transports fats throughout the cell.
|
|
|
Ribosome
|
Ribosomes function as factories to produce proteins. Found in the ER and some in the cytoplasm. Read RNA instructions and use them to make proteins.
|
|
|
Golgi Body
|
The Golgi body receives proteins and other newly formed materials from the ER, packages them, and distributes them to other parts of the cell. Sent out of the cell, to the membrane, and some become a lysosome.
|
|
|
Chloroplast
|
Chloroplasts capture energy from sunlight and CO2 and use it to produce food for the cell. Oxygen is a waste product.
|
|
|
Vacuole
|
Vacuoles are the storage areas of cells. It stores food, water, and waste. Animal cells have many samll ones or none while plants have one large one.
|
|
|
Lysosome
|
Lysosomes are small, round structures containing digestive enzymes that break down cold organnelles and big food particles.
