Unit 1, AOS1, Chapter 2A: Cells as the Basis of Life

Identify the 8 criteria of living things (hint: MRS GREEN)

Movement, Respiration, Sensitivity, Growth, Reproduction, Equilibrium, Excretion and Nutrition

Identify the 3 central concepts of cell theory

1. All living things are made up of cells

2. Cells are the smallest and most basic units of life

3. All cells come from pre-existing cells

Identify the six kingdoms that classify all life and whether they are prokaryotic or eukaryotic

Eukaryotes: Protista, Fungi, Plantae, Animalia

Prokaryotes: Archaea, Bacteria

Identify the major difference between prokaryotic and eukaryotic cells

Eukaryotic cells contain membrane-bound organelles

Identify 4 things that prokaryotic and eukaryotic cells have in common

DNA, a plasma membrane, ribosomes and cytosol

Differentiate the DNA organisation of eukaryotic and prokaryotic cells

Eukaryotic cells: Multiple linear strands packaged in a chromosome, in a nucleus

Prokaryotic cells: One circular chromosome and

additional plasmids (circular loop of DNA)
