11.
Yusuf drew one cell from each of three samples: a lettuce leaf, a carrot root and his own cheek. Using the diagram, which cell came from his cheek?
Dr Dabour Hub Academy - figure 2
Cell Q, because it has no cell wall, no chloroplasts and no large vacuole
Cell R, because it has no chloroplasts, just like every animal cell
Cell P, because it has the most parts and humans are complex
Cell Q, because it is the only cell that has a nucleus
12.
The bar chart shows the approximate number of mitochondria in four types of human cell. Which cell type is likely to need the most energy, and why?
Dr Dabour Hub Academy - figure 3
Heart muscle cells, as their mitochondria make new energy from nothing
Heart muscle cells, as more mitochondria can release more energy from food
Fat storage cells, as they hold the largest store of food
Cheek lining cells, as they are on the outside of the body
13.
Two ways of adding a coverslip to a cheek cell slide are shown. Which method is better, and why?
Dr Dabour Hub Academy - figure 4
Method 1, because dropping it flat spreads the stain more evenly
Method 2, because the needle scrapes more cells onto the slide
Method 1, because the coverslip lands faster so the stain cannot dry
Method 2, because lowering it at an angle pushes out the air

two drops
one drop only
three drops
