TOPIC 1: Classification Of Life

Question 1

What are the 5 characteristics of living organisms?

Answer 1

• organized (consist of cells)
• metabolism
• respond to stimuli
• reproduce
• evolve

Question 2

Answer 5

Prokaryotes are single celled and microscopic while eukaryotes have many cells and are visible to the human eye

Question 6

Differences between domain bacteria and domain archaea

Answer 6

Bacteria
- circular chromosome, cell with peptidoglycen, bacteria like ribosomes, unbrached phospholipids

Domain Archaea
- cell wall has PSEUDO PEPTIDOGLYCEN, eukaryotic like ribosomes, branched phospholipids

Question 7
