Sia ? 3 years, 1 month ago

Hypotonic solution	Hypertonic solution
The solution outside the cell has a higher soluble concentration than inside the cell. Thus, the water molecules move outside the cell from inside.	The solution outside the cell has a less concentrated solution than inside the cell. Thus, the water molecules move inside the cell from outside.
A solution whose concentration is less than the cell sap or inside of a cell.	A solution whose concentration is more than the cell sap or that inside a cell.
A plant cell becomes turgid when putting in a hypotonic solution.	A plant cell undergoes plasmolysis in a hypertonic solution.

ANSWER

Unit cell is the smallest portion of a crystal lattice which, when repeated in different directions, generates the entire lattice. Generally unit cell is considered as in cubic shape. A unit cell is characterised by six parameters. Unit cells can be broadly divided into two categories, primitive and centred unit cells. When constituent particles are present only on the corner positions of a unit cell, it is called as primitive unit cell (simple). When a unit cell contains one or more constituent particles present at positions other than corners in addition to those at corners, it is called a centred unit cell (bcc, fcc and ecc). In each cell, the contribution of constituent particles at the corner is 1/8 and at the face centre is 1/2 and at the edge centre is 1/4 and at the centre of body is whole constituent atom. Q.1. How many constituent particles are present in a simple cubic unit cell? (a) 1 (b) 2 (c) 3 (d) 4 (e) 5 Q.2. How many constituent particles are present in a body centred cubic unit cell? (a) 8 (b) 6 (c) 4 (d) 2 (e) 0 Q.3. How many constituent particles are present in a face centred cubic unit cell? (a) 0 (b) 8 (c) 6 (d) 3 (e) 4 Q.4. How many parameters are of a unit cell (a) 6 (b) 4 (c) 2 (d) 0 (e) 8 Q.5. A substance is made up of two elements X and Y and crystallize in fcc. If X is present at the corners and Y present at the face centres then what will be the formula of the substance? (a) XY (b) XY4 (c) X4Y (d) X3Y4 (e) XY3
