Animal Cells and Organelles
Nucleus - Controls the Cell ( Contains DNA)
Mitochondria - Releasing energy through respiration
Cytoplasm - Site of chemical reactions
Cell Membrane - Controls what goes in and out of the cell
Ribosomes - Site of protein synthesis
Epithelial = Skin Cell
Plant Cells and Organelles
Nucleus - Controls the Cells
Mitochondria - Releases energy through respiration
Choloroplasm - Site of chemical reactions
Cell Wall - Supports the Cell
Membrane - Controls what goes in and out
Ribosomes - Makes protein
Vacuole - Contains Cell Sap
Plant Cell Structure and Specialisation
Region where most chemical reactions take place = Cytoplasm
A large , permanent space containing fluid = Vacuole
Abosrbs light energy = Chloroplast
Controls the activities of the cell = Nucleus
Gives the cell strength and support = Cell Wall
Controls the passage of substances in and out of the cell = Cell Membrane
Xylem vessel - transport water and dissolved mineral ions up the plants
Root hair cell - main site of photosynthesis
Leaf cell - absorbs water and dissolved mineral ions from soil
Xylem cell - one way only , no end walls between cells , water and minerals , thick walls stifferned with lighting.
Vascular tissue in plants which conducts water and dissolved nutrients upwards from the root. Basic Function - transports water from roots , stems and leaves. It also transports nutrients.
Prokaryotic cell - found in bacteria and cyanobacteria. ( They contain no nucleus)
Eukaryotic - found in protista , fungi, olants and animals. ( They contain nucleus)
Organelles - This means cell part
Flagellum - the tail
Cell differentiation and mitosis
During the development of a multi-celled organism cells differentiate to form specialised cells. They do this by acquiring different sub-cellular structures.
- one cell splits into two identical daughter cells ( Cloaning)
- Before the cell can be divided the chromosome have to divide in number.
Mitosis is the process of cell division in our bodies. There are 6 stages in the process.
