describe cell structures, including the nucleus, cytoplasm, cell membrane, cell wall, chloroplast and vacuole

describe the functions of the nucleus, cytoplasm, cell membrane, cell wall, chloroplast and vacuole

animal cell structure: 

Nucelus an organelle which contians genetic material that controlls the cells activity and is surrouned by its own membrane 

cell membrane  this membrane forms the outer surface of the cell and controls the substances that move in and out of the cell 

cytoplasm; gel like substance where most of the cell's chemical reaction take place, it also contians enzymes which control these reactions 

plant cell structure 

chloroplast is where photosyntheisis takes palce  which makes food for the…
