Chloroplast - for photosynthesis, uses light energy to produce starch
What are 2 structures present in plant cells but not in animal cells?
Chloroplasts and cell walls
Name structures W to Z in the diagram
W - cell membrane
X- cell wall
Y- capsule
Z- flagellum
Name the biological molecule in
W- cell membrane = phospholipids
X- cell wall = murein
what is the process by prokaryotic cells divide
Binaryfission
give 2 ways in which the arrangement of prokaryotic dna is different from arrangement of human dna.
prokaryotic dna is circular as opposed to linear
Prokaryotic dna is also notassociated with proteins
Write evidence that
cell b is an animal cell
Cell c is a prokaryotic cell
B - no cell wall
C- has a capsule
Cell A is a plant cell. name a polysaccharide which may be found in cell a but not in an animal cell
Cellulose
Penicillin is an antibiotic. It prevents the formation of bacterial cell walls. as a result bacterial cells that have been treated with penicillin swell and burst.
Suggest why penicillin has no effect on plant cells.
Plant cell wall is made of a differentsubstance
two structures found in a prokaryotic cell that are not found in human cells.
Cell wall, capsule
