Exp:B Xylem and phloem are known as complex tissues as they both are made up of more than one type of cells. These cells work in a coordinated manner, as a unit, to perform the various functions. Xylem helps in conducting of water and minerals. Xylem are composed of tracheids, xylem parenchyma, vessels and xylem fibres.

Which of the following is removed in girdling experiment?
1 Bark only
2 Bark with phloem
3 Phloem only
4 Completely vascular tissue
Explanation:
Exp:B 'Bark with phloem' is removed in girdling experiment. This experiment is used to identify the tissue through which the food is transported. In this experiment bark (Phloem) is removed from the wood by a process known as girdling. When a ring of bark is removed from a woody plant, the woody xylem part remains intact, which causes the water and the nutrients to reach the leaves.

Phloem conducts food by
1 perforated sieve plates
2 bast fibres
3 xylem parenchyma
4 xylem fibres
Explanation:
Exp:A Phloem conduct food by perforated sieve plates. Sieve plates are connecting and transport tissue in plant. Sieve plate allows the food to pass through the phloem tubes. The tiny pores present on these tubes help in the transport and absorption of food particles. These have long and elongated structures that connect the roots and all other parts of plants.

The function of a vessel is
1 conduction of food
2 conduction of water and minerals
3 conduction of hormones
4 All of the above
Explanation:
Exp:B The function of vessel (present in xylem) is conduction of water and minerals. In plants, the same set of pipe-like vessels transport water, mineral salts and food. It is present only in angiosperms. Vessels are longitudinal channels composed of perforated cells.
