- Plastids are present, except fungi.
Animal cell:
- Cell wall absent.
- Nucleus present near centre.
- Usually centrosome is present that helps in formation of spindle fibres.

<u><em>-Describe the structure of an ATP module.
</em></u>
ATP plays an important role in releasing and storing energy in cells. It is an ideal source of energy because ATP easily releases and stores energy by breaking and re-forming the bonds between its phosphate groups. The ATP module is composed of three components. These phosphates are the key to the activity of ATP.
