Answer 10

Prokaryotes and eukaryotes

Question 11

Name the characteristics of prokaryotes

Answer 11

• do not have a true nuclei
• not enclosed by a nuclear membrane so it floats freely in the cytoplasm
• no true organelles occur in the cytoplasm
• Bacteria is prokaryotes

Question 12

Characteristics of eukaryotes

Answer 12

• have a true nuclei
• DNA is enclosed in a nuclear membrane and therefore occurs in the nucleus
• true organelles occur in the cytoplasm
• Protista , fungi , plantae and animalia are eukaryotes

Question 13

Name the characteristics of kingdom monera

Answer 13

• bacteria is unicellular
• are prokaryotes
• bacterium cell is surrounded by cell wall
• some bacteria is autotrophic

Name the 3 types of heterotrophic bacteria

Answer 14

1. Parasitic - one suffers one benefits
