Question

Which of the following is the characteristic of dicots?
A. Seeds have two cotyledons.
B. Have prominent primary roots.
C. Leaves show reticulate venation.
D. All of the above.

Answer 1

Hint: All flowering plants, or angiosperms, were previously split into two groups: dicotyledons and dicots. The name relates to one of the group's distinguishing characteristics, specifically the presence of two embryonic leaves, or cotyledons, on the seed.

Complete answer:
Plants that are dicotyledonous are also known as dicots. These plants have two cotyledons, or embryonic leaves. They have almost 200,000 different species. Dicots include garden plants, shrubs, and trees, as well as broad-leaved blooming plants including magnolias, daisies, roses, geraniums, cactus, peas, mint, hollyhocks, and many others.
The plants are usually trees or shrubs that are perennial. Plants can be both annual and biennial. There aren't many herbs in this group.
Dicotyledonous plants give rise to tap roots.
In a few dicotyledonous plants, the stem is branched, and underground stems arise.
Dicotyledonous plants have broad leaf blades that remain parallel to the earth's surface. Sheathing leaf bases are not provided for the leaves.
The seed coat and the fruit coat are not united, and the seeds are non-endospermic in most cases.
The embryo is relatively large, with two cotyledons and a thick cotyledon.
There are three types of vascular bundles: conjoint, collateral, and open. It is made up of three parts: xylem, phloem, and cambium. Bi-collateral vascular bundles are possible.
Reticulate venation is present on the leaves.
Pentamerous, tetramerous, or multiples of 5 blooms are the most common.
True roots, or main roots, are developed and are usually branching.

Hence Option D is the correct answer.

Note: Within the dicotyledons, the eudicots are the biggest clade. The structure of their pollen distinguishes them from all other flowering plants. Eudicots have tricolpate pollen, which has three or more pores placed in furrows called colpi, whereas dicotyledons and monocotyledons have monosulcate pollen, or forms evolved from it.
