Question

The statements given below describe certain features that are observed in the pistil of flowers.
I. Pistil may have many carpels.
II. Each carpel may have more than one ovule.
III. Each carpel has only one ovule.
IV. Pistil have only one carpel.
Choose the statements that are true from the option below.

• A. I and II
• B. I and III
• C. II and IV
• D. III and IV

Answer 1

The correct option is A I and II

Each pistil is constructed of from one to many enrolled leaflike structures, or carpels, each of which encloses one or more ovules. The carpel is a single megasporophyll, or modified seed-bearing leaf. A pistil then may be composed of one carpel (simple pistil), as in the sweet pea, or of two or more carpels (compound pistil) partially or completely joined, as in the mustard (two carpels) or lily (three carpels). A carpel has three parts: stigma, ovary, and style. The stigma is responsible for pollination and is the top-most part of the carpel. The ovary is responsible for determining the number of carpels in a plant and is the bottom-most part of a carpel. Lastly, the style is responsible for connecting the stigma and ovary together, helping with the transfer of pollen through the carpel for pollination.

So, the correct option is 'Option A'.
