1. What are eukary- Cells that are more complex and have a nucleus (animal and plant cells)
otic cells?
2. What are Cells that are smaller and simpler, and don't have a nucleus but still have genetic
prokaryotic cells? information (bacteria)
3. What are eukary- Organisms made of eukaryotic cells
otes?
4. What is a A prokaryotic cell (it's a single celled organism)
prokaryote?
5. What is cyto- A liquid gel in which most of the chemical reactions needed for life take place. It
plasm? contains enzymes that control these chemical reactions
6. In what types of Animal, plant, algae, and bacteria cells
cells is cytoplasm
found?
7. What is the cell It holds the cell together and controls the passage of substances in and out of the
membrane? cell
8. In what types Animal, plant, algae, and bacteria cells
of cells is a
cell membrane
found?
9. What is the nu- It carries the instructions for making new cells or organisms and controls all
cleus? activities of the cell
10. In what types of Animal, plant, and algae cells
cell is a nucleus
found?

11. What is the cell It is made of cellulose in plants and peptidoglycan in bacteria. It strengthens and
wall? supports the cell.
12. In what types of Plant, and bacteria cells
cell is a cell wall
found?
13. What are chloro- They are found in the green parts of a plant, and they contain chlorophyll which
plasts? allows the cell to create food and light energy
14. In what types of Plant, and algae cells
cell are chloro-
plasts found?
15. What are ribo- They are the site of protein synthesis. All the proteins needed in the cell are made
somes? here. The ribosomes are attached to the RER (rough endoplasmic reticulum)
16. In what types Animal, and plant cells
of cell are ribo-
somes found?
17. What are mito- They are structures in the cytoplasm. Oxygen is used, and energy is released
chondria? during respiration here
18. In what types Animal, plant, and algae cells
of cell are mito-
chondria found?
19. What is a perma- It is a space in the cytoplasm filled with cell sap. It is important for keeping the
nent vacuole? cell rigid to support the plant

cell is a per-

found?
21. What is a plas- A small, circular piece of DNA that carries genes additional to those in the main
mid? genetic material
22. What two fea- Chloroplasts and mitochondria
tures do bacteria
cells NOT have?
23. How do light mi- They use light and lenses to form an image of a specimen and magnify it
croscopes work?
24. What can we see Individual cells and large sub-cellular structures, like nuclei
using a micro-
scope?
25. What do electron Electrons
microscopes use
to form an im-
age?
26. Out of electron Electron microscopes
and light mi-
croscopes, which
has a higher res-
olution?
27. What can we see The internal structure of mitochondria and chloroplasts, ribosomes, and plasmids
with electron mi-
croscopes?
28. Magnification is image size divided by real size

crometres into
millimetres?
30. What is a flagel- Locomotion
lum for?
31. In what type of Bacteria
cell is a flagellum
found?
32. What are nerve Carry impulses around an organism. They provide a quick communication system
cells specialised
to do?
33. What are four Lots of dendrites to connect with other cells
adaptations of Axon that carries nerve impulses from one place to another
nerve cells? Synapses adapted to pass impulses on using transmitter chemicals
Long so they cover more distance
34. What is differen- The process where a cell changes to become specialised
tiation?
35. What are stem Undifferentiated cells
cells?
