6. What is needed if a protein is produced?
- The DNA needs to make proteins
- The protein needs to be correct
- The gene needs to be switched on
- The gene needs to be switched off
7. What does glandular tissue do?
- Contracts to release digestive juices
- Churns food and and digestive juices
- Releases digestive juices e.g. enzymes
- The inner/outer layer of cells
8. What's the fancy word for when the water outside and inside a plant cell is equal
- Turgid
- Cell membrane
- Flaccid
- Vacuole
9. What does muscle tissue do?
- Separates food and digestive juices
- Contracts to churn food and and digestive juices
- Contracts to release digestive juices
- The inner/outer layer of cells
10. Name when osmosis will occur into the cell
- Turgid - Hypotonic
- Flaccid
- Plasmolysed - Hypertonic
11. What's the correct statement about a SEM?
- Samples can be live or dead
- It has a higher resolution that TEM
- It has a lower magnification that TEM
- It's 2D
12. What's the carbon dioxide conc. like inside a leaf compared to the air outside
- It's lower because it's being used up in cells
- It's higher because it's being produced in the cells
13. What's the oxygen conc. like inside a leaf compared to the air outside
- It's higher because it's being produced in the cells
- It's lower because it's being used up in cells
14. What happens if specialised cells work together?
- They make organs
- They make tissues
- They make cells
- They make specialised tissue
15. Pick the equation relating image size, magnification and specimen size
- image size = magnification/specimen size
- specimen size = image size x magnification
- magnification = image size/ specimen size
- magnification = image size x specimen size
16. What is different about active transport and why?
- It goes against the concentration gradient because it needs energy from mitochondria
- It goes against the concentration gradientso therefore doesn't need to go against the concentration gradient
- It doesn't go across a partially permeable membrane so it needs lot of energy
- It doesn't go across a partially permeable membrane so it doesn't need energy
17. What does DNA do?
- Makes nucleotides
- Makes different proteins
- Codes for different proteins
- Makes sure the cell is working
18. What is a plant stem cell?
- A cell that will differentiate into an unspecialised cell
- A specialised cell that can differentiate into any type of plant
- An unspecialised cell that can differentiate into any type of plant
- A cell that can become specialised
19. Name when there is no net movement in osmosis
- Turgid - Hypotonic
- Flaccid
- Plasmolysed - Hypertonic
20. What is differentiation?
- When an undifferentiated cell turns into a differentiated cell
- When a differentiated cell turns into an undifferentiated cell
- When an unspecialised cell turns into a specialised cell
- When a specialised cell turns into an unspecialised cell
