BIOL - How Substances Move In and Out of Cells
Biology, diffusion, osmosis, active transport - IGCSE | IBDP | DSE | GCE | IAL | AP Chemistry
Substances can enter and leave cells through the cell membrane. The 3 main ways substances are transported in and out of cells are:
For IGCSE Biology, it is important to understand the processes of these 3 modes of transport.
For example, if we look at the picture above ☝️
Osmosis in animal and plant cells
When animal and plant cells are placed in a dilute or concentrated solution, the results of osmosis are different. This topic is frequently asked in IGCSE Biology.
