The cell membrane is a thin semi-permeable membrane that surrounds the cell. Its purpose is to hold the structure of the cell, protecting and enclosing all of the other organelles within it. The semi-permeable membrane enables substances to move in and out of the cell.
The nucleus is like the brain of the cell. It is the biggest organelle in the cell, containing the DNA and also controls the activity within the cell. The nuclear membrane is very similar to the cell membrane as it is semi-permeable allowing protein to move out of the nucleus.
The cytoplasm is a semi-fluid like substance within the cell, this is where many of the chemical reactions take place. These reactions are called metabolism, this involves the use and release of energy from chemical substances. The cytoplasm moves slowly within and around the cell
The mitochondria’s (mitochondrion-singular) main purpose is the breakdown of glucose to release the energy which is then able to be used by other organelles within the cell. This energy is extremely important as without it the cell would be unable to function properly.
The endoplasmic reticulum (rough and smooth) can be shortened to RER and SER are both there to enable the transport of substances around the cell. The RER has ribosomes attached to it which enables it to make proteins and store them. Whereas the SER is involved in the metabolism of lipids and fats.
The ribosomes main function is to create protein for the cell to use. Ribosomes are small circle shapes that are ‘free flowing’ within the cytoplasm. They only have a short life span and once that is up they are either reused to create the proteins or broken up and broken down within the cytoplasm.
The Golgi apparatus/complex’s main function is to modify, sort and package proteins and is also involved in the
