Cell structure

Cell Labeling Practice

1. Nucleolus - region found within the cell nucleus that is concerned with producing and assembling the cell's ribosomes.
2. Ribosome- non-membrane bound organelles that serve as the site for protein synthesis in the cell.
3. Smooth endoplasmic reticulum - is a membrane system of folded sacs and interconnected channels that serves as the site for protein and lipid synthesis - this type does not have ribosomes bound to it.
4. Golgi apparatus - is a flattened stack of membranes that modifies, sorts, and packages proteins.
5. cytoskeleton- is a supporting network of long, thin protein fibers that form a framework for the cell.
6. Cell membrane- semi-permeable bilayer found in all cells that separates the interior of the cell from the outside environment.
7. Rough endoplasmic membrane - is a membrane system of folded sacs and interconnected channels that serves as the site for protein and lipid synthesis - this type does have ribosomes bound to it.
8. microtubules- part of the cytoskeleton that functions during cell division.
9. Nucleus - contains most of the cell’s DNA, which stores information used to make proteins that determine a cell’s growth, function, and reproduction.
10. Cytoplasm - the environment enclosed by the plasma membrane which is a semifluid material that the organelles are found in.
11. Lysosome - vesicles that contain substances that digest excess or worn-out organelles and food particles.
12. Mitochondria - powerhouse of the cell; converts fuel into usable energy.
13. vacuoles- a membrane-bound sac used for temporary storage.
14. Cell wall- a thick, rigid mesh of fibers that surrounds the outside of the plasma membrane.
15. chloroplasts- capture light and convert it into chemical energy in a process called photosynthesis.
