Cell structures and functions GapFill

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

Animals and  humansplantsmitochondriaribosomes have different kinds of cells. They share many features, including having a nucleus and a cell  wallhairmusclemembrane. Cells that contain a nucleus are known as  prokaryoteseukaryotesplasmidsbacteria. Other types of cells, that do not contain a nucleus, are known as  eukaryoteschloroplastsplasmidsprokaryotes.

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

The  nucleusplasmidcytoplasmcell wall, 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  cell wallcytoplasmcell membranemitochondrion, which in plants and algae is made of  nucleic acidscelluloseproteinsstarch and provides strength to the cells. Additionally, a permanent vacuole is likely present. The permanent vacuole is full of  RNAwateramino acidssap.

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