Introduction:
Plants parts can be classified into two; the aerial parts and the underground parts. Aerial parts are those parts that are found above the ground. In a plant, there are two types of organs. They are the vegetative organs and the reproductive organs. Both the organs are present above the ground.
Answer to Problem 1MCQ
Correct answer:
Among the given organs, flower is not a vegetative organ, it is a reproductive organ. Therefore option c. is correct.
Explanation of Solution
Reason for the correct statement:
Reproductive organs are those organs that take part in the process of reproduction. They are involved in the generation of seeds and fruits and in the development of a new flower and a new plant.
Vegetative organs are those organs that are not involved in the process of reproduction. They are involved in many other processes like the growth of plant, ascent of sap, growth, and origin of new branches and many other activities like making food for the plant, and transpiration.
Option c. is given as “flower”.
As, “flower is not a vegetative organ but a reproductive organ”, is the right answer.
Hence, the option c. is correct.
Reasons for the incorrect statements:
Option a. is given as “stem”.
Stem is a vegetative organ. It is not involved in the process of reproduction and seed formation. So, it is a wrong answer.
Option b. is given as “leaf”.
Leaf is a vegetative organ it makes food by the process of photosynthesis. It is not involved in the process of seed formation or reproduction. So, it is a wrong answer.
Option d. is given as “root”.
Roots are the underground organs of a plant. They absorb food and nutrients from the soil; hence, it is a vegetative organ not a reproductive organ. So, it is a wrong answer.
Hence options a., b., and d. are incorrect.
Flower is a reproductive organ and not a vegetative organ as it is involved in making seeds and new plants.
