Question

Sunflower is a
A. Dicot
B. Monocot
C. Pteridophyte
D. Non-flowering plant

Answer 1

Hint:- Sunflowers are flowering plants which are mostly grown in temperate regions and tropical regions. They are typical annual plants of genus Helianthus. The scientific name is Helianthus annuus. The flowers are round-headed in combination with the ligules that look like the sun held by a long stalk. They typically grow in summer.

Complete Answer:-A dicot plant produces two cotyledons at its premature stage. At the time of germination dicot plants produce two leaves. The roots and shoots part of dicot plants is quite different from monocot plants. The leaves of dicot plants bear reticulate venation whereas in monocots the leaves exhibit parallel venation. The roots of dicotyledons are branched whereas the monocotyledons have fibrous roots.
The term dicot refers to dicotyledons that have two cotyledons and monocot refers to monocotyledons having one cotyledon at an early stage.

The cotyledons reserve food in them which is used during germination of seeds. Pteridophytes are the types of plants which produce no flowers or fruits. These plants are vascular and reproduce using spores. Non-flowering plants do not produce flowers at all. Pteridophytes are one kind of non-flowering plants.

Hence from all the above options, the correct answer is option (A) – Dicot.

Note:- Sunflowers are originated from America. The sunflowers are quite diversified under the genus Helianthus. Sunflowers grow strictly based on genetic makeup and background. Their growth and development are visible especially in the middle of summer. A series of reproductive stages are identified by only visualizing the heads or main branch of a single head or branched head.
