Question

Which of the following statements is are true?
P) Vascular bundles in plants have simillar function as blood in animals.
Q) Excretory products are produced in both plants and animals.
R) Meristematic tissue in plants are constandly dividing.
S) Sclerenchyma cells are responsible for photosynthesis.

• A. P, Q, and R only
• B. P, R, and S only
• C. Q, R, and S only
• D. P, Q, R and S

Answer 1

The correct option is A P, Q, and R only

• Vascular bundles in plants consist of xylem and phloem. Xylem transport water and nutrients whereas phloem transport food to different parts of plant body.
• Blood in animals has a similar function of transporting nutrients, water, oxygen, etc., to different parts of body .
• Excretory products are produced in both plants and animals. Plant excretory products are gums, latex, resins, etc., whereas urine, faeces, sweat, etc., are animal excretory products.
• Cells in meristematic tissue are constantly dividing. These cells are responsible for the increase in length, thickness, branching, flower stalk formation in plants.
• Sclerenchyma cells have a very thick cell wall. They provide mechanical support to the growing tissues.
• It is the chlorenchyma cells (parenchyma with chloroplasts) which are involved in the process of photosynthesis.
