Answers
Answer:
Explanation:
1.) oldest type of cell is prokaryotic ( cell which do not have nucleus).
2.) prokaryotes don't has nucleus while eukaryotes has a nucleus ,
prokaryotes are single celled, while eukaryotes can be single celled or multi celled.
3.) ORGANELLES means organs of cells as their size are very tiny , so they are called organelles. like mitochondria,cell wall, nucleus, golgi apparatus etc.
4.) organelles do many functions for cell,
eg.1) like cell wall do protection for cell
eg.2) mitochondria(power house of cell) stores energy in form of ATP molecules
5.) Eukaryotic type of cell
6.) the membrane of nucleus can protects the DNA from injuries
7.) the Flagellum is a long Zig-zag like structure that helps the single celled organism to move .
8.) yes, cilia can also be found in humans ,
For eg. In FEMALES cilia is found in fallopian tubes that helps in the movement of ovum from ovary to uterus .
Finally completed. thanks for asking the question, i hope i was able to answer all your points. if you didn't find it helpful, then I am deeply sorry.
Good luck my friend. Best Of Luck.
