B1: Quiz 1 – Answers
1)
a)
2)
a)
3)
a)
c) A flagellum rotates which allows the bacteria cell to move. The bacteria cell uses the flagellum to move towards beneficial substances (like nutrients or oxygen) and away from harmful substances (like toxins).
d)
i) No (bacteria cells do not have mitochondria)
ii) No (bacteria cells do not have chloroplasts)
e) Prokaryotic
4)
a) Eukaryotic cells are larger
b) In eukaryotic cells, the genetic material is stored in a nucleus. Whereas, in prokaryotic cells, the genetic material is not stored in a nucleus (the genetic material is free to move around the prokaryotic cell)
c) Eukaryotic cells are more complex
d)
i) Many cells
ii) Single cell
a)
- A) Nucleus – controls the cell and stores genetic material
- B) Cell membrane – controls what substances enter and leave a cell. Also, provides a boundary between the cytoplasm and the outside of the cell
- C) Mitochondria – where aerobic respiration reactions happens
- D) Cytoplasm – a gel like substance where most of the chemical reactions in a cell take place
- E) Ribosomes – responsible for protein synthesis
2)
a)
- F) Permanent vacuole – contains cell sap, which is a weak solution of sugars, minerals and salts
- G) Chloroplasts – where photosynthesis takes place
- H) Cell wall – strengthens and supports the cell (made from cellulose)
3)
a)
- I) Chromosomal DNA
- J) Flagellum
- K) Plasmids
- L) Cell wall
c) A flagellum rotates which allows the bacteria cell to move. The bacteria cell uses the flagellum to move towards beneficial substances (like nutrients or oxygen) and away from harmful substances (like toxins).
d)
