Can someone help me with these?

Prokaryotic Cells are usually smaller and overall have less structures and organelles to them, while Eukaryotic Cells have far more structures and organelles.

We learnt what what Eukaryotic Plant and Animal Cells have in common and then the differences between them such as plant cells have cellulose cell walls and animal cells have microvilli.

However I am confused about Prokaryotic Cells. We have a diagram of one which has Pili, Flagella etc. as well as a cell wall made up of peptideglycan (different to prokaryotic). But are Prokaryotic Cells also split up into animal and plant? Can a prokaryotic cell NOT have a cell wall? When we learnt it we talked about it being bacteria, but I didn't know bacteria had a cell wall...

Can anyone help me to see sense?

Animal cells and plant cells both come under the 'Eukaryotic cells' branch; animal and plant cells are not Prokaryotic cells.

Also, bear in mind that not all animal cells have microvilli, e.g. red blood cells. You're thinking of epithelial cells in the small intestine of mammals

Bacteria have cell walls; penicillin, an antibiotic which is used to destroy some types of bacteria, works by breaking down bacterial cell walls. Bacteria which are resistant to penicillin produce the enzyme penicillinase, which breaks down penicillin, so it no longer affects those specific bacteria.

Lastly, peptidoglycan is a type of polymer, like cellulose - it is not a type of cell 'different to prokaryotic', which is what you think

The information on this website is pretty good, so read through it if you have some time

Yeah in our notes we have that microvilli is in specialised cells such as epithelial cells in the small intestine. Sorry I meant different to Eukaryotic. I meant to say that prokaryotic cells are made of peptideglycan and eukaryotic are made of cellulose.

I will read the link, thanks, but is a good way to think of it that Eukaryotic Cells have plant and animal cells under the eukaryotic heading and then prokaryotic cells have bacteria cells under the prokaryotic heading?

Can prokaryotes be without a cell wall?

Haven't come across that before - normally in an exam question what they would do would be: to show diagrams of two different cells (one prokaryotic and one eukaryotic) and label / explain the differences if they tell you the cell's function; and to show diagrams of an animal cell and a plant cell (both eukaryotic), and label the differences, e.g. plant cells have a permanent vacuole, chloroplasts and cellulose cell walls, which animal cells don't
