Draw animal cell
Cell membrane
It is a very thin layer that surrounds the cells
Function of cell membrane
Its function is to hold the cell content in its place and control what passes into an out of the cell
Example of cell membrane function
Example is when we exercise our muscle cells allow glucose and oxygen to pass in from our blood cell to supply energy to the cells
Nucleus and function
The nucleus is normally around, its function is to act as the control center of the cell
Cytoplasm
Cytoplasm is a watery liquid found between the nucleus and the cell membrane
Cytoplasm function
Its function are to carry out some Cell reactions and two support tiny cell structures
Plant cells
Plant cells have five main parts
A cell wall
A cell membrane
Cytoplasm
Nucleus
Vacuole
