The cell is the most basic unit of life. Every living thing you see around you is composed of cells, from the biggest animal in the world to the smallest multicellular animals. Then there are organisms that have their entire bodies made up of just a single cell. We also learnt how plant cells differ from animal cells and the various special organelles that each of them possess. The presence of a cell wall is the main defining feature of plants since animals do not possess the same.
Furthermore, we know why plants can produce their own food – their cells contain special organelles that contain structures called chlorophyll and this helps them convert sunlight and carbon dioxide into food and oxygen. Animal cells on the other hand breakdown food molecules, which in turn releases energy. Then there are viruses, these are entities that fall somewhere in between a living and a non living thing. Their cells do not contain any cell organelles like a normal plant or an animal cell but have genetic material that is used to replicate itself once inside a host.
