|
Cell Membrane
|
The cell membrane controls what substances come into and out of a cell. The barrier between the cell and its environment.
|
|
|
Cell Wall
|
The cell wall is a rigid layer of nonliving material that surrounds the cell of plants and some other organisms. Found in plant cells and in bacteria.
|
|
|
Chloroplasts
|
Site of photosynthesis, which is making food from sunlight energy, and CO2. Oxygen is a waste product.
|
|
|
Chromatin
|
The thin strands that surround the nucleolus that are the answer to how the nucleus "knows" how to direct a cell. Contains genetic material (DNA).
Instruction: Genes Copies of genes are called RNA. |
|
|
Cytoplasm
|
Outside the nucleus is the cytoplasm, the region between the cell membrane and the nucleus. The cytoplasm is a thick, clear, gel-like fluid. Suspends organelles and dissolves important chemicals needed for life.
|
|
|
Endoplasmic Reticulum
|
The rough ER (rER) transports proteins from ribosomes to the ribosomes to the Golgi body. rER is covered in ribosomes.
|
|
|
Golgi Bodies
|
Receives proteins from the rER, sorts them, packages them, then send them to other parts of the cell (membrane, becomes lysosome) or out of the cell.
|
|
|
Lysosomes
|
Lysosomes are small, round structures containing digestive enzymes which break down old worn out organelles and big food particles.
|
|
|
Mitochondria
|
Mitochondria= singular
Mitochondrion= plural Converts energy from food into energy that the cell can use. It requires energy and has a double membrane. |
|
|
Nucleus
|
The nucleus is like the cell's control center, directing all of the cell's activities, including reproduction.
|
|
|
Nucleolus
|
A small object floating around that makes the ribosomes.
|
|
|
Nuclear Envelope
|
Protects chromatin (DNA) and materials pass in and out through the pores.
|
|
|
Organelle
|
These tiny cell structures, called organelles, carry out specific functions within the cell.
|
|
|
Ribosomes
|
Ribosomes make proteins and is found on the endoplasmic reticulum or in the cytoplasm. It reads the RNA instructions and uses them to make the protein.
|
|
|
Vacuoles
|
Stores food, waste, and water. Animal cells have many small ones, or none at all. Plant cells have one big one.
