CELLS

Two types of cell

Eukaryotic cell

Prokaryotic cell

Three main parts:

-Membrane cell-Cytoplasm

-Nucleus

Animal cell

• Golgi apparatus• Cell membrane• Nucleus• Centrioles• Endoplasmic

reticulum• Cytoplasm• Ribosomes• Lysosome• Mithocondrion• Nuclear

membrane

Plant cell• Cell wall• Vacuole• Membrane cell• Lysosome• Cytoplasm• Chloroplast• Nucleus• Nucleolus• Mitochondria• Endoplasmic• Reticulum• Golgi complex

Specialised cells:

-Leaf cell-Root hair cell

-Sperm cell-Red blood cell

-Egg cell-Nerve cell

Leaf cell

• light energy

• photosynthesis

• chlorophyll

Root hair cell

Water and mineral ions from the soil

Sperm cell

• Fertilises • Egg cell• Head

gametes• Tailmove

Red blood cells

• haemoglobin oxygen cells.

Egg cell

• Large

• Much cytoplasm

Nerve cell

• Long• Connection• Electrical

signals

Diffusion

Movement of particles from an area of higher concentration to a area of lower

Osmosis
