Cells
Organisms can be Prokaryotes or Eukaryotes
All living things are made of cells
Cells can either be
Eukaryotic
Are complex and include Animal and Plant cells
Procaryotic
Smaller and simpler, e.g. Bacteria
Eukaryotes are organisms that are made up of Eukaryotic cells
A Prokaryote is a Prokaryotic cell ( it's a single-celled organism )
Plant and Animal cells have Similarities and Differences
The different parts of a cell are called sub-cellular structures
Most Anamal cells have the following sub-cellular structures:
Nucleus - contains Genetic Material that controls the activities in the cell
Cytoplasm - gel-like substance where most of the Chemical Reactions happen
It contains enzymes that control chemical reactions
Cell Membrane - holds the cell together and controls what goes In and Out
Mitochondria - these are where most of the reactions for Aerobic Respiration take place
Respiration transfers Energy that the cell needs to work
Ribosomes - these are where Proteins are made in the cell
Plant cells usually have All The Bits that Animal cells have, plus a few Extra things that Animal cels Don't have:
Rigid Cell Wall - made of Cellulose
It Supports the cell and strengthens it.
Permanent Vacuole - these ae where Photosynthesis occurs, which makes Green substance called Chlorophyll. which absorbs the Light needed for Photosynthesis
Bacteria Cells Are Much Smaller
Bacteria are Prokaryotes
Bacteria Cell:
Don't have Chloroplasts or Mitochondria
Cytoplasm
Cell Membrane
Cell Wall
Don't have a Nucleus - it is really and Singular Circular Strand of DNA that floats freely in the Cytoplasm
Possible to contain one or more small rings of DNA called Plasmids
