Question

1. Write a note on the structure ofcell.
2. Give difference between colloidal solutions and suspensions

Answer 1

$\huge\sf\underline\pink{Answer\:⟹}$

1)

⟹A cell consists of three parts:-

The cell membrane, the nucleus, and, between the two, the cytoplasm. Within the cytoplasm lie intricate arrangements of fine fibers and hundreds or even thousands of miniscule but distinct structures called organelles.

2)

⟹ Colloidal Solution :-

A colloid is a mixture in which one substance of microscopically dispersed insoluble or soluble particles is suspended throughout another substance. Sometimes the dispersed substance alone is called the colloid; the term colloidal suspension refers unambiguously to the overall mixture.

⟹ Suspension :-

A suspension is a heterogeneous mixture in which solute-like particles settle out of a solvent-like phase sometime after their introduction. We apply the word 'suspension' when particles are big enough to eventually settle. If the particles are too small to ever settle, they are said to form a colloid.
