Cell

Living & Non-Living
A living thing can grow, move, reproduce, sense, respire and excrete. For example a living thing is Humans and Animals because they can all do these things. A Non-Living things is exactly the opposite of a Living thing. They can not row, move, reproduce, sense, respire and excrete. They are basically dead.

Cell Structure


 Cell membrane: very thin transparent sheet that holds everything inside & controls what comes in & out.

Cell wall: made of cellulose & only found in plants, thick & strong, provides strength for the plant.


Nucleus: usually a small dark circular spot. The control centre for the cell & contains  genes.

Cytoplasm: watery jelly like substance which fills most of the cell. It holds the cell organelles and contains nutrients & chemicals.

Vacuole: water filled bubble that helps to keep the cell firm

Chloroplasts: small green structures found only in the green part of plants. They make sugar for the plant.


Mitochondria: the part of the cell that does respiration to give the cell energy.
