Question

Write one main function of the following:

i. Xylem
ii. Phloem
iii. Stomata
iv. Hydathodes
v. Leaf spines.​

Answer 1

Answer:

1. Xylem transport water and minerals From root to whole plant body
2. Phloem transport food to whole plant body

Answer 2

Answer:

Main function of the following are

i) Xylem - Xylem is the tissue of vascular plants that transports water and nutrients from the soil to the stems and leaves. Xylem plays an essential 'supporting' role providing strength to tissues and organs, to maintain plant architecture and resistance to bending.

ii) Phloem - Phloem is the vascular tissue in charge of transport and distribution of the organic nutrients. The phloem is also a pathway to signaling molecules and has a structural function in the plant body.

iii) Stomata - Stomata, the small pores on the surfaces of leaves and stalks, regulate the flow of gases in and out of leaves and thus plants as a whole. They adapt to local and global changes on all timescales from minutes to millennia.

iv) Hydathodes - Hydathodes are the structures that discharge water from the interior of the leaf to its surface in a process called guttation.

v) Leaf spines - The predominant function of thorns, spines, and prickles is deterring herbivory in a mechanical form. In some cases, spines have been shown to shade or insulate the plants that grow them, thereby protecting them from extreme temperatures.
