Cells
In this topic, we were taught the differences between a typical plant cell and an animal cell. Also, we were taught how to draw the cells. This was of some difficulty as we were not allowed to use rulers to draw the plant cell and it was difficult to draw a 'perfect' circular cell membrane of an animal cell.

Transport in Living things
The transport in living things are due to two processes: Diffusion and Osmosis.
Diffusion is the net movement of particles from a region where they are at a higher concentration to that of a lower concentration. It is the basis of the exchange of oxygen and carbon dioxide taking place in the lung's air sacs.
