Cell structures and functions GapFill

All living organisms, no matter how big or small, are made of  cellsorganslipidswater.

Animals and  humansribosomesmitochondriaplants have different kinds of cells. They share many features, including having a nucleus and a cell  musclewallmembranehair. Cells that contain a nucleus are known as  bacteriaprokaryotesplasmidseukaryotes. Other types of cells, that do not contain a nucleus, are known as  chloroplastseukaryotesplasmidsprokaryotes.

Bacteria are an example of this type of cell, and they are much smaller than  ribosomesvirusesprokaryoteseukaryotes. The genetic material in bacterial cells takes the form of  nucleiloopsribosomeschains.

The  cytoplasmplasmidcell wallnucleus, that is present in all cell types, is a jelly-like substance that contains all the chemicals needed by the organism. Two structures are present in plant cells that are not found in animal cells. These include a  mitochondrioncell membranecell wallcytoplasm, which in plants and algae is made of  proteinsnucleic acidsstarchcellulose and provides strength to the cells. Additionally, a permanent vacuole is likely present. The permanent vacuole is full of  amino acidswaterRNAsap.

In order to supply energy, cells contain a number of  mitochondriaplasmidscell membraneschloroplasts. They can provide energy for making proteins, which takes place on  vacuolesnucleiribosomesplasmids.
