Question

Which of the following plants is used to extract Colchicine?

• A. Tulip
• B. Colchicum
• C. Aloe
• D. Asparagus

Answer 1

The Correct Option is B

Earthworms have bristle-like structures called setae on their body segments. These setae help the earthworm move and anchor itself in the soil as it burrows. In most earthworm species, the setae are arranged in paired rows on each segment of the body.
However, the arrangement of setae is slightly different in certain segments. The first segment of the earthworm, called the peristomium, usually lacks setae. The last segment, known as the pygidium or anal segment, also typically lacks setae. Additionally, the clitellum, which is a glandular and reproductive structure found in certain segments, does not have setae either.
So, the correct answer is option (D) The first, last, and clitellum segments.
