Question

Taproots are commonly found in
A) Gymnosperm
B) Angiosperm
C) Dicots
D) Monocots

Answer 1

Taproot is a type of root. Taproots can be easily identified as a primary root with supplementary smaller roots in horizontally. The main root penetrates deep in the soil to absorb water from depth.

Complete answer:
Monocotyledons have seed with one cotyledon while dicots have seeds with two cotyledons that is why these are called monocots and dicots respectively.
Taproots are significant features of dicotyledon plants.
Taproots have a central, large primary root out of which many smaller roots originate that is called primary and then secondary roots and so on. The main primary root develops from the radicle region of the seed.

Additional information:
Based on the shape and structure the taproots can be further categorized into

Conical - carrot
Fusiform - radish
Napiform- turnip
Other plants that have taproots are beetroot, sugar beet, and dandelion.

So, the correct answer is option Dicot.

Note: Other types of the root along with taproot are fibrous root and adventitious roots. The fibrous roots are roots with a short life span. In fibrous roots the rootlets can not be differentiated into primary or secondary root, they all arise from the same point.
The adventitious roots are modified roots that are formed in response to the unfavourable condition such as a flood. These are formed from non-root tissues.
Monocot plants have an adventitious root generally.
