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 |
