Answer 1

Answer:

Q1. The cell organelles that is non- membranous is ribosomes

Answer 2

1)ribosomes

2)

• Prokaryotes lack an organized nucleus and other membrane-bound organelles.
• Prokaryotic DNA is found in a central part of the cell called the nucleoid.
• The cell wall of a prokaryote acts as an extra layer of protection, helps maintain cell shape, and prevents dehydration.

3) Diffusion is the movement of particles from an area of higher concentration to lower concentration.

the tendency of a fluid, usually water, to pass through a semipermeable membrane into a solution where the solvent concentration is higher is called osmosis

4) genes are located in chromosomes

5)Adenosine Triphosphate

6)Amoeba obtain its food by endocytosis or phagocytosis

7)ser means smooth endoplasmic reticulam and rer means rough endoplasmic reticulam

hope it helps .....

jst know tht ....no one will answer these much questions for 5 points...so better post these questions for more points to get full answer!!

stay safe and hv a nice day
