2 The functions of the different organelles

Annotations:

  • The Nucleus The nucleus is the control centre of the cell and dictates what all of the other organelles do. The nucleus also stores the DNA. Endoplasmic Reticulum The endoplasmic reticulum is where most chemical reactions take place. The cell makes lipids and other chemicals, and it sometimes has ribosomes attached. RibosomesRibosomes are the only organelle that every cell has, including bacteria. Ribosomes take information from the DNA and use it to make proteins.Golgi ApparatusThe golgi apparatus is essential in packaging different products from the endoplasmic reticulum and the ribosomes into their final form. If a product needs to be sent to other cells, the golgi apparatus packs it and sends it out.MitochondriaMitochondria are often referred to as the powerhouses of the cell. Mitochondria take in sugar and create ATP, the type of energy your cells need to function.Plasma MembraneThe plasma membrane, or cell membrane, is not just the covering of the cell. It also plays a vital role in getting nutrients into the cell and sending waste products out.
3 Specialised cells

Annotations:

  • The shape, size and features of a cell are related to its function. A cell is specialised as it only has to, and only can do one job. It could not be any other cell as it is not adapted to be one. If we didn't have these special cells we would have serious medical issues.
