Question

Eustele is characteristic of
A. Monocots
B. Dicots
C. Pteridophytes
D. Bryophytes

Answer 1

Hint: Eustele – Is arrangement, in the primary vascular tissue include vascular bundles. It is normally in one or two rings around the pith. In addition to being found in stems of plants, the Eustele appears in the roots of monocot flowering plants too. However, it is really just a variant of the Eustele found in monocot plants. So, Eustele is the characteristic of dicots and not of monocots, pteridophytes or bryophytes.

Complete answer:
Option - A - Monocots
Monocotyledon, or monocot terms referred to one of two groups of flowering plants, or in biological terms angiosperms.

Option – B – Dicots
Dicotyledons, also called dicots or more rarely dicotyle, are words used to describe one of the two groups into which all the flowering plants or angiosperms were formerly divided. The term refers to one of the typical features of the group, namely that the seed has two embryonic leaves or cotyledons.

Option – C – Pteridophyte
Pteridophyte is a vascular plant with both xylem and phloem that disperses spores. Because pteridophytes produce neither flowers nor seeds; they are referred to as "cryptogams" at times. It means that their means of reproduction is hidden.

Option – D – Bryophytes
Bryophytes are an informal group that includes three main divisions of non-vascular land plants known as embryophytes: the liverworts, hornworts and mosses are some of its examples.

Thus, the correct answer is option B- Dicots.

Note: Eustele in some green flowering plants is considered as a characteristic of Monocotyledons too. In Eustele the flowers consisted of vascular packets of both xylem and phloem beaches with parenchyma compartments between the bundles. In monocots, the vascular bunches of Eustele also lead to being approaching the surface of the stem.
