Question

Anomocytic type of stomata are found in the leaves of

• A. Fox glove
• B. Atropabelladona
• C. Urgeniaindica
• D. Cassia acutifolia

Hint:

Cassia acutifolia (senna) is a good example of a plant with anomocytic stomata.

Answer 1

The Correct Option is D

Step 1: Understanding Anomocytic stomata.
Anomocytic stomata (also known as paracytic stomata) are characterized by having guard cells that are surrounded by a group of similar cells. These stomata are commonly found in plants like Cassia acutifolia (senna).
Step 2: Analyzing the options.
(A) Fox glove: This plant is known for having anomocytic stomata, but it is not the typical example used in textbooks.
(B) Atropabelladona: This plant does not exhibit anomocytic stomata.
(C) Urgeniaindica: Not typically associated with anomocytic stomata.
(D) Cassia acutifolia: Correct — Cassia acutifolia, or senna, has anomocytic stomata.
Step 3: Conclusion.
The correct answer is (D) Cassia acutifolia, as it is a known plant with anomocytic stomata.

Answer 2

Stomatal type is a classic pharmacognosy identification character. Let's approach it by recalling which stomatal pattern is linked to which listed plant/drug.

1. Fox glove: The leaf of foxglove (Digitalis) is classically described as showing anisocytic (unequal-celled) stomata, where the guard cells are surrounded by three subsidiary cells of unequal size, not the anomocytic pattern.
2. Atropa belladonna: Belladonna leaf is a textbook example of anisocytic stomata as well, the same three-unequal-subsidiary-cell arrangement, again not anomocytic.
3. Urginea indica: Being a monocot (squill), its leaf epidermis characteristically shows the diacytic or paracytic stomatal pattern typical of many monocotyledonous leaves, not the anomocytic type.
4. Cassia acutifolia: Senna leaf is the standard pharmacognosy example of the anomocytic (ranunculaceous) type, where the guard cells are surrounded by an irregular number of subsidiary cells that are not clearly distinguishable from the ordinary epidermal cells.

Matching the anomocytic stomatal pattern specifically to its textbook plant example points to senna.

Therefore, the correct answer is Cassia acutifolia.
