Answer
b. Phloem.

12. Following may be a part of xylem tissue:

  • a. Tracheids.
  • b. Vessel.
  • c. Xylem parenchyma.
  • d. Xylem fibers.
  • e. All.
Answer
e. All.

13. The xylem which forms first and later respectively is:

  • a. Protoxylem, metaxylem.
  • b. Metaxylem, protoxylem.
  • c. Xylem parenchyma.
  • d. None.
Answer
a. Protoxylem, metaxylem.

14. Arrangemnet of xylems in stems is:

  • a. Exarch
  • b. Mesarch
  • c. Endarch.
  • d. None.
Answer
a. Exarch.

15. Arrangemnet of xylems in stems is:

  • a. Exarch
  • b. Mesarch
  • c. Endarch.
  • d. None.
Answer
c. Endarch.
Explanation
In stems protoxylem is at centre and the metaxylem are at perifery. This is exarch condition. In roots arrangement of xylems are oppostite to the what we see in stem. The condition is endarch.

16. Which part of the plant tissue system contain stoma and guard cells?

  • a. Epidermis
  • b. Cuticle.
  • c. Pith.
  • d. None.
Answer
a. Epidermis

17. Stoma closes when turgour pressure in guard cell:

  • a. Increase.
  • b. Decrease.
  • c. Closure of stoma does not depend on turgor pressure.
  • d. None.
Answer
b. Decrease.
Explanation
Flaccid condition.

18. Ground tissue include all except:

  • a. Epidermis.
  • b. Vascular tissue.
  • c. Both.
  • d. None.
Answer
c. Both.

19. Ground tissue of leaves that contain  chlorophyll containing cells in the plant is:

  • a. Cuticle.
  • b. Epidermis.
  • c. Mesophyll.
  • d. Endodermis.
Answer
c. Mesophyll.

20. Open vascular bundle is present in:

  • a. Dicot stem.
  • b. Dicot root.
  • c. Monocot stem.
  • d. None.
Answer
a. Dicot stem.
Explanation
In dicot stem some undifferentiated tissue is present. This we call cambium. It forms vascular bundle in later stage, so we call them open. In monocot cambium is absent.

Explanation
In monocot root pith is large and well developed with poyarch xylem (more than six)

 

28. Ring arrangement is a characteristic of :

  • a. Monocot root.
  • b. Monocot stem.
  • c. Dicot root.
  • d. Dicot stem.
Answer

  • b. Glucose.
  • c. Minerals
  • d. Sucrose.
Answer
a. Water.
Explanation
Some cells of epidermis in grass modify into bulliform cells. In the scarcity of water, these cells curl and reduce loss of water.

  • b. Sapwood.
  • c. Both.
  • d. None.
Answer
b. Sapwood.
Explanation
Older xylems in the plant lignify and form hearttwood. They donot conduct water and mineral. Sap wood contains secondary xylem and are alive. They conduct water and mineral.
