What 3 things do plant cells have that animal cells do not have?

The equation to calculate magnification
The equation to calculate magnification
If a cell is 50µm in size and the image of it down a microscope is 2mm in length, what is the magnification of the microscope?
2mm= 2000µm so M = 2000/50 = 40X
These are found in the nucleus and code for
different characteristics.
Chromosomes
where is chlorophyll found in plant cells
Chloroplasts
Which feature do bacterial cells NOT have
Nucleus (their DNA is free floating in cytoplasm)
Other than a plant cell, which other type of cell often has a cell wall?
Bacterial cells
