Task 2
On your posters or another piece of paper, describe the function of the
components that you have labeled for the prokaryotic cell, the eukaryotic cell
and the virus.


Prokaryotic cell

Cell wall:
Only found in prokarotic cells (such as plants fungi and bacteria)
-surrounds the plasma membrane
-gives the cell its shape
-prevents bursting when turgid pressure is high
-helps anchor appendages like pili and flagella
-composed of cellulose microfibers which form a thick wall
-grows with the cell
-helps the cell maintain osmotic balance

Plasma membrane:
In prokarotic cells
-encloses the interior of the cell
-regulates the flow of material in and out of the cell

Cytoplasm:
In prokarotic cells
-carries out functions for all growth, metabolism and replication
-composed of water, enzymes and nutrients, wastes and gasses
-gel-like matrix
-contains cells structures (such as ribosome)

Ribosomes:
In prokaryotic cells (70s)
-translates the genetic code from the DNA to make proteins (proteins are molecules that
perform all the functions of cells and living organisms)
-they are random throughout the cytoplasm - unattached
-composed of 2 subunits

Nucleoid:
Only in prokaryotic cells
-not a membrane bound nucleus
-an area of the cytoplasm where the strands of DNA are found
