Question

Which of the following is not a vegetative part of the plant?
A. Carpel
B. Thalamus
C. Stipules
D. Calyx

Answer 1

Hint: Vegetative parts are not directly involved in sexual reproduction. They are often used in asexual forms of reproduction. Roots, stem, shoot buds, and leaves are vegetative parts of the plant.

Complete answer: Outer plant structures, for example, leaves, stems, roots, fruits, seeds are known as plant organs. Every organ is a composed gathering of tissues that cooperates to play out a particular function. These structures can be divided into two groups: sexual reproductive and asexual reproduction (vegetative reproduction).
-Vegetative parts incorporate roots, stems, shoot buds, and leaves, they are not legitimately associated with sexual reproduction. Vegetative parts are often used in asexual forms of reproduction such as cuttings, budding, or grafting.
-Carpels or gynoecium is the female reproductive part of the flower. A carpel comprises three sections to be a specific stigma, style, and ovary. Depending upon the number of carpels, gynoecium can be monocarpellary, bicarpellary, or polycarpellary.
-Thalamus or receptacle is a vegetative part, on which reproductive organs are present.
-A stipule is a small outgrowth on either side of the base of the leafstalk.
-Calyx or sepals is the outermost whorl and is meant for the protection of the other floral parts. The sepals which have shading other than green are called petaloids.
So, the correct answer is option A-Carpel.

Note: Carpel/gynoecium is the female reproductive unit. When more than one carpel is available, they might be free (as in lotus and rose) and are called apocarpous, or if fused then it is called syncarpous (Petunia, Mustard, Tomato).
