Answer 2

Why do you think it is? It would be easier to tutor you if you explained what about the question is giving you trouble.

Answer 3

Eukaryotes are those whose cell has a
\(\bullet\) Membrane bound nuclear nucleus.
\(\bullet\) Membrane bound organelles like Mitochondria & chloroplasts.
\(\bullet\) True genetic material i.e chromosomes with histone proteins.
\(\bullet\) Larger 80s ribosomes.

Answer 5

Bacteria

Bacteria are single celled prokaryotes.
No organelles - only a cell wall, cell membrane, DNA, and enzymes
Cell wall - not rigid like a plant cells, but flexible and gooey composed of peptidoglycan
Useful as a signal to other bacteria
Can protect pathogenic bacteria from host's defenses
Cell membrane - semipermeable, like all cell membranes
DNA - single loop of DNA, with numerous plasmids
enzymes - do all of the work of organelles, all spread out within the cytoplasm
Not completely true - some internal "compartmentalizaiton" - is this the road to organelles???
Most diversity is biochemical, not morphological (they are kind of restrained here)
