We as humans are a type of multicellular organism meaning that we consist of many different cells which make up our body. One example of these cells would be the red blood cells which help to carry oxygen around the body using something called haemoglobin. Unlike most of the cells in our body red blood cells do not have a nucleus allowing them to carry more oxygen.

Another cell in the human body would be which blood cells, acting as guards protecting us from illness and infection which blood cells hound down and engulf harmful bacteria in our bodies eliminating and collecting data on the bacteria.

Like most animals humans are made up of the same cells (animals cells, a type of eukaryotic cell) which have many different organelle to help it function such as the nucleolus, contained in the nucleus it helps to produce and assemble the cells ribosomes which can be found in the cytoplasm of the cell as well as attached to the rough endoplasmic reticulum and is used to produce protein. Another organelle in the cell would be the mitochondria witch is a beneficial bacteria in the cell used to produce chemical energy, which is stored in a small molecule called ATP, by allowing it to feed off of carbohydrates in the cell.

Like plant cells, animals cells also have a vacuole although it is much smaller it performs the same function allowing the cell to hold water.

Another organelle possessed by animal cells is called the Golgi apparatus, other wise known as the Golgi body or simply the Golgi is responsible for transporting, modifying and packaging proteins and lipids into something called vesicles allowing them to be transported out of the cell.

The organelles in animal cells are all contained in something called a cell membrane which is processed by all cells, this cell/plasma membrane acts as a fence keeping everything in the cell but also keeping thing out of the cell. However along this cell membrane there are ‘gates’ called transport proteins which allow select molecules needed by the cell to pass through using ATP produced by the mitochondria to open and close.
