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 🙋🙋♀️🙋♂️:
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 🌿🌱🍀:
On the other hand, under a light microscope, a typical plant cell photomicrograph looks as follows:
![Onion epidermal cell photomicrograph (i.e., plant cell photomicrograph) Onion epidermal cell photomicrograph (i.e., plant cell photomicrograph)](http://custom-images.strikinglycdn.com/res/hrscywv4p/image/upload/c_limit,fl_lossy,h_9000,w_1200,f_auto,q_auto/2451083/175131_368808.jpeg)
The above image shows an onion epidermal cell.
A plant cell typically comprises the following features:

🧠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.
⚠️📝Note and remember that:
- Plant cells are often larger than animal cells
- Animal cells DO NOT contain cell walls, permanent vacuoles and chloroplasts
- Plant cells DO NOT contain centriole.
All done! See you next time! 🙌
