Answer:
In flowers vegetative propagation will not occur
Answer: The answer is generally no, but sometimes yes.
Explanation: We grow to our full adult size via an increase in the number — not the size — of our cells. But some of our cells can change size and this can be for healthy or not-so-healthy reasons.
Hope this helps! ^^
Answer:
1- They have circular DNA, RNA and 70s ribosomes
2- They reproduce by binary fission
3- They can synthezise ATP
Explanation:
Mitochondria and chloroplasts are semi-autonomous organelles that are similar in many aspects:
- Both of them have a similar size with bacterias,
- Both of them have enzymes that synthesize ATP,
- Both of them have DNA, RNA, and 70s ribosomes, these last ones characteristic of prokaryotes. They are capable of synthesizing proteins. Their DNA is circular and double-stranded,
- Both of them reproduce by binary fission, as prokaryotes do.
Because of all of these characteristics, mitochondria and chloroplasts are suggested to be once free-living bacterias.
