  1. They absorb green light.

  2. They do not absorb red light.

  3. They reflect blue light.

  4. They reflect green light.

  5. They generate wavelengths of green light when they absorb sunlight.

Show answer
Correct Option: D
Explanation:
Plants appear green due to the presence of chlorophyll. Chlorophyll is a pigment present in the chloroplasts of the plants that absorbs in the blue and red region of light spectrum and reflects green light making the plants to look green. Thus, plants appear green because they reflect green light.
So, the correct answer is they reflect green light.

 Plants use polymers of glucose as storage molecules and as structural components in their cell walls. Which of the following polysaccharides would be found in a plant?
 I. Starch
 II. Glycogen
 III. Cellulose

  1. I only

  2. II only

  3. III only

  4. I and II only

  5. I and III only

Show answer
Correct Option: E
Explanation:

Cellulose forms an integral part of the cell wall which provides strength and rigidity to the cell. It helps to maintain the structural integrity of a particular cell. Cellulose is a complex polysaccharide which is made up of  β(1→4) linked D-glucose units.

Starch is the important food reserve for the plants. The excess amount of glucose synthesized during dark reaction of photosynthesis is stored in food vacuoles of the plant which it again converted into a usable form of glucose in case of unfavorable conditions. It is a complex polysaccharide formed by 1,4-alpha linkage between two glucose unit.
So, the correct answer is option E.

The organelles found in 4 different types of cells are shown in the table below. Use the information in the table to answer the next 3 questions.

Which cell type will undergo the process of photosynthesis?

  1. Cell 1 only

  2. Cell 2 only

  3. Cell 2 and 3 only

  4. Cell 3 only

  5. Cell 3 and 4 only

Show answer
Correct Option: B
Explanation:
Photosynthesis occurs in chloroplasts. Chloroplasts are the green coloured plastids which contains various pigments necessary for photosynthesis.
Since only cell 2 has the chloroplast, so it will undergo the process of photosynthesis.
So, the correct answer is 'Cell 2 only'.

Archegoniatae include

  1. Bryophytes, Pteridophytes and Gymnosperms

  2. Pteridophytes, Gymnosperms and Angiosperms

  3. Algae, Fungi and Bryophytes

  4. Algae, Fungi and Bacteria

Show answer
Correct Option: A
Explanation:

An archegonium is a multicellular structure or organ of the gametophyte phase of plants, producing and containing the ovum or female gamete. The archegonium has a long neck canal or venter and a swollen base. Archegonia are located on the surface of the plant thallus. Plants having archegonium is known as archegoniate. Bryophytes, pteridophytes and gymnosperms are archegoniate plants. so option A is correct.

  4. Cycas

Show answer
Correct Option: B

The plant which lives for several years called as

  1. Annual

  2. Biennials

  3. Perennials

  4. None of the above

Show answer
Correct Option: C
Explanation:

A perennial plant or simply perennial is a plant that lives more than two years. Some sources cite perennial plants being plants that live more than three years. The term is often used to differentiate a plant from shorter-lived annuals and biennials.

Thus the correct answer is C. 

Which of the following differentiates mosses from ferns?
