Question

Sunflower is a
A) Dicot
B) Monocot
C) Pteridophytes
D) Non-flowering plants

Answer 1

Hint:The plants are classified on the basis of their physiological structure, arrangement of tissue, dicotyledonous and non-dicotyledonous plants, and flowering and non-flowering plants.

Complete answer:
To answer this question, we have to know details about dicotyledonous plants. A cotyledon within a seed is the embryo part. Often the cotyledons may become the seedlings first leaves when the germination of seed takes place or during the beginning of its growth. Botanists use as classification means the number of cotyledons found in the seed. Monocots are the seeds that have cotyledons and the dicots have two cotyledons. Prior to the germination process the cotyledons formed during embryogenesis with the shoot and the roots of the plants. The cotyledons in the dicot plants have photosynthetic functions like leaves. It is the first part that emerged from the ground. Some of the cotyledons last for some days after they come out of the soil and some take a long period of time to grow.
Now, the plants like guava, sunflower, papaya, rose, tamarinds, mango, radish, castor, etc are a dicot plant that means they bear two cotyledons.

Hence, the correct answer is ‘A’. Dicot.

Note:The pteridophyte involves the plants that neither have seeds nor have the flowers. They involve plants like herbs, ferns, mosses, and horsetail. As they are non-flowering plants they reproduce through spore formation, in other words, they are sporophytic in nature.
