Which of the following is not the molecule of information :

  1. Protien

  2. DNA

  3. RNA

  4. Deoxyribose
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

DNA contains the genetic information necessary for the synthesis of RNA and thereby all proteins necessary for the cell to function. RNA is a sequence of nucleotides that contain information for the synthesis of proteins. Deoxyribose is a sugar present in the nucleotides of DNA. Proteins are also provide  information. 

So, the correct option is  'Deoxyribose'

Leaves appear green because they reflect green color from light spectrum. The part in the leaf that is responsible for the reflection is

  1. Inner membrane of Chloroplast

  2. Thylakoid space

  3. Thylakoid membrane

  4. Stroma
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Chloroplasts are green because they contain the green pigment chlorophyll in their thylakoid membranes. Chlorophyll is a pigment that absorbs red and blue light. So plants are green because chlorophyll reflects green light. 

So, the correct option is 'thylakoid membrane'.

Which of the following statements is false regarding the experiment carried out for photosynthesis?

  1. The two leaves experiment proved that photosynthesis took place only in the green part of the leaf which is exposed to sunlight

  2. Half leaf experiment indicate that co2 is required for photosynthesis

  3. In half experiment some part of leaf is inserted in a test tube having soaked cotton

  4. Starch is formed in a leaf
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Variegated leaves have green parts (where the cells contain chlorophyll) and white parts (where there is no chlorophyll). Only the parts that were green become blue/black with iodine solution, showing the importance of chlorophyll in photosynthesis. The parts without chlorophyll do not photosynthesize, and so they do not make starch and the iodine does not change colour.
So the correct option is 'The two leaves experiment proved that photosynthesis took place only in the green part of the leaf which is exposed to sunlight'.
