1. Cells that do not have a distinct nucleus are called:
A eukaryotic
B prokaryotic
C multicellular |
2. Cells that have internal membranes surrounding specialised organelles are:
A prokaryotic
B unicellular
C eukaryotic |
3. The controlling organelle within a cell is the:
A nucleolus
B nucleus
C gene |
4. The nucleolus is made of large nucleic acids called:
A DNA
B REM
C RNA |
5. The jellylike fluid that contains nutrients in a cell is the:
A cytoplasm
B vacuole
C nucleus |
6. Small organelles that are responsible for protein synthesis are the:
A RNA
B ribosomes
C genes |
7. The system of membranes that help transport chemicals such as proteins through the cell is the:
A golgi body
B endoplasmic reticulum
C ribosome |
8. The organelles that are responsible for collecting, sorting, processing and distributing proteins and carbohydrates are the:
A ribosomes
B golgi bodies
C plastids |
9. The organelle found in both animal and plant cells that is clear but contains dissolved nutrients is the:
Avacuole
Bcytoplasm
Ccentriole |
10. The 'powerhouse' of the cell that generates the cell's energy-rich ATP molecules is the:
Amitochondrion
Bchloroplast
Cnucleus |
11. The organelle responsible for photosynthesis is the:
Amitochondrion
Bvacuole
Cchloroplast |
12. A difference between prokaryotic cells and eukaryotic cells is that:
Aall prokaryotes have a cell wall and eukaryotes only have cell membranes
Beukaryotes are living but prokaryotes are viral
Cprokaryotes lack internal membranes |
13. The total of all the chemical reactions occurring in an organism is called the:
Abasal rate
Bcarrying capacity
Cmetabolism |
14. A main difference between an animal cell and a plant cell is that:
Aplant cells have both cell membranes and cell walls, but animal cells only have cell membranes
Bplant cells have no vacuoles
Canimal cells have no mitochondria |
15. The correct order from smallest to largest is:
Aorganelle, cell, tissue, organ, system, organism
Bcell, organ, organism, tissue, atom, molecule, system, organelle
Catom, molecule, tissue, organ, organelle, organism |
