1.1.a Compare the structure of typical animal and plant cells by making temporary preparations of live material and using photomicrographs
ANIMAL CELL PHOTOMICROGRAPH ๐๐โโ๏ธ๐โโ๏ธ:
A photomicrograph is a photograph of an object taken with a microscope.
When looking under a light microscope, a typical animal cell photomicrograph looks as follows:
The above image shows a cheek epidermal cell.
An animal cell typically comprises the following features:
PLANT CELL PHOTOMICROGRAPH ๐ฟ๐ฑ๐:
On the other hand, under a light microscope, a typical plant cell photomicrograph looks as follows:
The above image shows an onion epidermal cell.
A plant cell typically comprises the following features:
๐ง For your GCE CIE Biology exam, it is important to be able to compare photomicrographs and identify the different structures of plant and animal cells.
โ ๏ธ๐Note and remember that:
- Plant cells are often larger than animal cells
- Animal cells DO NOT contain cell walls, permanent vacuoles and chloroplastsย
- Plant cells DO NOT contain centriole.
All done! See you next time! ๐
