Eukaryotic cells have a…
nucleus, cell membrane and cytoplasm and include animal and
plant cells.
Cell membrane controls the
movement of substances into and out of a cell.
Cytoplasm is a…
jelly like substance where reactions take place inside a cell.

Magnification equation
Magnification = image size ÷ actual size
1mm in μm- Micrometer
1mm = 1000 μm
1μm- Micrometer in nm- Nanometer
1μm = 1000nm
Electron microscopes give greater…
magnification and resolution.
Electron microscopes can allow people to see more … structures
subcellular
Mitosis allows cells to divide for…
Growth, repair and development of an embryo
3 stages of (GCSE) mitosis
1) DNA is copied and mitochondria and ribosome are increased.
2) Chromosomes are pulled to either end of the cell and the nucleus divides.
3) The cytoplasm and cell membranes divide into 2 genetically identical cells.
