Give four things commonly found in plant cells but not in animal cells
Cell wall, Plasmodesmata, Vacuole, Chloroplast
1 of 12
What is an oval shaped organelle surrounded by a double membrane. The inner membrane is folded and projects into the inner space, which is filled with a grainy material.
Mitochondria
2 of 12
A collection of flattened membrane 'sacs' arranged roughly parallel to one another. Small, circular structures are seen at the edges of those 'sacs'.
Golgi apparatus
3 of 12
Function of mitochondria
Aerobic respiration
4 of 12
Golgi Apparatus
Processes and packages new lipids and proteins
5 of 12
In which organelle would you expect radioactivity to appar first and expain why?
Ribosomes because this is where protein synthesis occurs
6 of 12
After 5 minutes the Golgi apparatus has become radioactive, which other organelles would become radioactive by this time?
Rough endoplasmic reticulum, ribsosomes and vesicles
7 of 12
What is the function of the vesicles
Vesicles transport substances in and out of the cell and between organelles
8 of 12
Give four functions of the cytoskeleton
Supports the cells organelles, strengthens the cell maintaining shape, Transport materials around the cell, enables cell movement
9 of 12
An insect is 0.5mm long. In a book a picture of the insect is 8cm long. Calcuate the magnification
Magnification=length of image/length of object, =80mm/0.5mm, x160
10 of 12
Name the organelles that would be visible using a light microscope
Mitochondria and nucleus, the resolution of a light microscope is not good enough to show objects smaller than 0.2
11 of 12
Which organelles would be visible using an SEM and explain why
All of the organelles would be visible. SEM can resolve objects down to about 5nm or 0.005
