1)The plasma membrane is the most outer covering of the cell. 2)It separates the content of the cell from its external environment. 3) The plasma membrane allows or permits the entry and exit of some material inside and outside of the cell. 4)It also permits the entry of some materials too. 5) Therefore, it is also known as selectively permeable membrane. 6) Due to its flexibility it helps some organisms (such as amoeba) to engulf food through the process of endocytosis.

(GIVEN) Distance = 100 km Speed while traveling= 60km /h (1) Speed while returning= 40km/h(2) To find time T= D/S Case 1 : 100/60 5/3 hrs Case 2:100/40 5/2hrz *Average speed* = total distance / total time = 100+100/5/3+5/2 200/(l.c.m) 10/6+15/6 200/25/6 200×6/25 8×6 ===✓48 km/h is your answer

'Osmosis is a special kind of diffusion'.Comment

Posted by Sanaj Dahiya 1 week ago

CBSE > Class 09 > Science

2 answers

Tanvi Arora 5 days, 20 hours ago

“Osmosis is the term used to refer specifically the diffusion of water across a differentially or selectively permeable membrane.” Yes, osmosis is a special type of diffusion because in both cases there is a movement of particles from a higher concentration region to a lower concentration region.

1Thank You

Sanaj Dahiya 1 week ago

Osmosis is diffusion through semipermeable membrane. Diffusion can take place in all 3 states (solid, liquid, gas) but osmosis take place only in liquid. And in diffusion, the movement of either solute or solvent occurs in both directions whereas in osmosis there is only undirectional flow of solvent. Hence, osmosis is a special kind of diffusion.
