Cell structure

Question 1

what kind of cells are animal and plant cells

Answer 1

eukaryotic

Question 2

what do animal cells contain

Answer 2

cell membrane, nucleus, mitochondria, ribosomes, cytoplasm

Question 3

what do plant cells contain

Answer 3

cell membrane, nucleus, mitochondria, ribosomes, cytoplasm, cell wall, vacuole, chloroplasts

Question 4

what characteristics do prokaryotic cells have

Answer 4

-single celled
-no nucleus, single loop of DNA
-small rings of DNA called plasmids
-smaller than eukaryotic

Question 5

3 differences between light and electron microscopes

Answer 5

light:
-cheap
-low resolution
-low magnification
electron:
-expensive
-high resolution (can see sub-cellular structures, like ribosomes)
-high magnification

Question 6

how do you calculate magnification

Answer 6

magnification=image size/actual size

Question 7

what is the purpose of specialised cells

Answer 7

specialised cells differentiate, which allows them to form different types of cells, like RBC, muscle cells and root hair cells.
