Plant and Animal Cells and Cell Division

Hey everyone. As preparation for my GCSE biology exams in May and June 2016 I decided that everyday I will do 5 pages of revision from my book and publish them to get revising. If you find something wrong or incorrect message me and I will correct it and re-upload it. Thanks! :)

Cell structure.
There are no generic "plant" or "animal" cells however there
generalisations we can make. When we refer to plant or animal cells
we usually refer to the generalised cells because these generalised
cells hold a majority of the things every animal or plant cell would
have. All cells have a cell membrane which is like a tiny wall that
keeps outside things out and holds the cytoplasm together. The
cytoplasm is where most reactions take place and the nucleus is
almost the command centre or the brains of the cell. Most but not
all cells have a nucleus.…read more

The cytoplasm is the liquid that keeps the cell together and keeps it
functioning. It is where different reactions take place and its where
all the different organelles, structures that have a specific role, for
example ribosomes. The cytoplasm holds fats, also known as lipids,
proteins and enzymes as well as the organelles. Enzymes control the
rate of which reactions in the cytoplasm happen and some are
suspended in one position but some move freely around in the
cytoplasm.…read more

Cell Membrane
The cell membrane is a thin layer around the cytoplasm and it holds
everything together and is almost like a bouncer, allowing certain
things into and out of the cell. Generally oxygen, food and water
are allowed in, waste products are allowed to go and harmful
products are kept out of the cell.…read more

That's amazing! Thanks so much.

Thank you so much



I found the  Powerpoint most helpful. Thanks



Helpful PowerPoint! It's at a great level of detail, sometimes some revision guides can give you way more than you need and it's really confusing. Thanks!
