YouTube Playlist: B1 – Characteristics of Cells

This video goes over the difference between plants and animal cells as well as the anatomy of plant cells.

This video explains animal cells and their structure. There is a lot more to do with the anatomy of animal cells than has been covered in the unit. Makes nice use of analogy.

Explains semipermeable membranes, and diffusion which is an important idea in this unit. This video also discusses osmosis.

Explains in greater detail the functions of a cell membrane how they work,  how they filter out what the cell needs and what they don’t.
