A transverse section of stem is stained ...

A transverse section of stem is stained first with safranin and then with fast green following the usual schedule of double staining for the preparation of a permanent slide. What would be the colour of the stained xylem and phloem ?
(A) Red and green
(B) Green and red
(C) Orange and purple
(D) Purple and orange

A

Red and green

B

Green and red

C

Orange and yellow

D

Purple and orange

Text Solution

Verified by Experts

The correct Answer is:
A
Red and green
Xylem tissue becomes red colour safranin and phloem tissue becomes green coloured due to last green. No other given by safranin and fast green.

An experimental setup of verification of photoelectric effect is shown in the diagram. The voltage across the electrode is measured with the help of an ideal voltmetar, and which can be varied by moving jockey 'J' on the potentiometer wire. The battery used in potentiometer circuit is of 20 V and its internal resistance is 2omega . The resistance of 100 cm long potentiometer wire is 8 omega . The photo current is measured with the help of an ideal ammeter. Two plates of potassium oxide of area 50 cm^(2) at separation 0.5 mm are used in the vacuum tube. Photo current in the circuit is very small so we can treat potentiometer circuit an indepdent circuit.
