Here are 3 great videos: estimation of osmolarity from Stephanie Castle; Mr Andersen talks us through an osmosis practical; and osmosis in potato strips from Bio Lab.
GCSE Bitesize –Cell Activity– covers animal & plant cells, movement in & out of cells & cell division (18m). Science in Focus –Cell Biology – a 19m video.
For self-assessment questions, with exercises and discussions, just click on the correct topic at Biology GCSE & IGCSE Question Bank. Powerpoints can be downloaded from the same sitehere.The s-cool revision sitelets you revise the topic, summarizes the topic & tests you on it. Skooolgives you a lesson, including progress questions, for each Biology topic but you’ll need sound on for it.

B2.1 CELL STRUCTURE
Science Bank 9 (Cells & Tissues): Part 1- Animal Cells (to 4m 25s); Part 2 – Plant Cells (to 9m 10s); you do not need Part 3.
A short video from The Virtual School about cells & specialized cells:
B2.2 MOVEMENT IN & OUT OF CELLS
You only need to know about the first two sections (diffusion):
Skooolgives you a lesson, including progress questions, for each Biology topic but you’ll need sound on for it. GCSE Bitesizehas revision pages (that take you through the topic), a test and an activity.
Or how about a whole lesson from Mr Paul Andersen? He goes into more detail than we need (we have to know about Dicots but not Monocots), but he’s good:
Mr Paul Andersen starts by defining transpiration as evaporation of water from a leaf. He then describes how a potometer can be used to measure the rate of transpiration in different environments:

CIRCULATION & BLOOD VESSELS:
GCSE Bitesize – Blood Circulation covers how the heart circulates blood & the composition of blood (6m 35s).
In Crash Course Biology #5 – In Da Club – Membranes & Transport, Hank describes how cells regulate their contents and communicate with one another via mechanisms within the cell membrane.
PRESCRIBED PRACTICAL 2 – Osmolarity
Estimation of osmolarity in tissues by bathing samples in hypotonic and hypertonic solutions
In Crash Course Biology #27 –Circulatory & Respiratory Systems, Hank takes us on a trip around the body – we follow the circulatory and respiratory systems.
