We decided to use school structure as an example. It's concrete walls supports our classes. In addition, there are designated corridors which allow us to travel via a specific route.

As humans have bones, we don't need extra support so animal cells don't include a cell wall. However, cells such as plant cells and bacteria cells will have one as they have no physical support like us.

Similarly like how the library stores information, copies of information can be made by photocopying - DNA Replication. Notes can be made to revise for an assignment - DNA Transcription. We leave the library with this information we've learnt and apply it when competing an exam - DNA Translation. If answer all questions correctly, the teacher gives us a merit - Protein formed !!!!

Contains floating ribosomes which link the amino acids together by peptide bones, forming proteins.

Link them together by condensation where water is released and a peptide bin forms between the Amine group and the carboxylic group (of the previous amino acid)

This turns them into glycoproteins and glycolipids which are used as receptors on cell surface membranes. Used for recognition and to link cells together to form tissues.

Help proteins and lipids leave cell - secreted out. The vesicles merges with cell membrane and becomes part of it

ATP broken down by hydrolysis reaction - where water is added. The enzyme ATP hydrolase is used in addition. This splits the phosphate and forms ADP and energy!! The free phosphate can bind to other compounds to make them more reactive so less energy needed to activate them now - phosphorylation.

Form protein spindle fibres which break down nuclear wall. Then cause the DNA to move to either poles - Metaphase.

Highly specialised mesophyll cells have a lot to maximise photosynthesis- capture more light.
