Levels of Organisation and Cell structure

Nucleus - contains the genes, which control the cell (control center).

Cytoplasm - chemical reactions like respiration happen here.

Cell surface membrane - lets some substances into the cell, and keeps others out.

Cell wall - makes a rigid box which supports the cell. 

Cell sap vacuole - stores sugar and makes the cel fill the cell wall.

Chloroplast - photosynthesis happens here.
