Vacuole
Centre of plant cell, full of sap
Chloroplast
Helps plant with photosynthesis, turns plant green
Microscope
An instrument to see specimens up close.
Specimen

Diffusion
Gas particles spreading out from areas of high concentration to low concentration.
Rate of diffusion.
How quickly gas particles diffuse.
Binary fission
