Which of the following statements is false?
I Epidermal cell has small amount of cytoplasm and a large vacuole
II. Waxy layer cuticle is absent in roots
III. Root hairs are unicellular, while stem hairs / trichomes are multicellular
IV. Trichomes - branched/ unbranched, soft / stiff and secretory or transpiration preventive
V. Guard cells are dumbell-shaped in dicots, and bean-shaped in monocots (e.g. grass)

Options

A. I
B. IV
C. III
D. V

Answer

To determine which statement is false, we will analyze each statement one by one.

**Step 1: Analyze Statement I**
- Statement I: "Epidermal cell has small amount of cytoplasm and a large vacuole."
- Analysis: This statement is true. Epidermal cells typically have a thin layer of cytoplasm and a large central vacuole.

**Step 2: Analyze Statement II**
- Statement II: "Waxy layer cuticle is absent in roots."
- Analysis: This statement is also true. Roots generally do not have a cuticle because they are not exposed to air and do not require a protective waxy layer.

**Step 3: Analyze Statement III**
- Statement III: "Root hairs are unicellular, while stem hairs/trichomes are multicellular."
- Analysis: This statement is true. Root hairs are indeed unicellular, while many trichomes on stems can be multicellular.

**Step 4: Analyze Statement IV**
- Statement IV: "Trichomes - branched/unbranched, soft/stiff and secretory or transpiration preventive."
- Analysis: This statement is true. Trichomes can vary in structure and function, being either branched or unbranched, and can serve various purposes including secretion and reducing water loss.

**Step 5: Analyze Statement V**
- Statement V: "Guard cells are dumbbell-shaped in dicots, and bean-shaped in monocots (e.g. grass)."
- Analysis: This statement is true. In dicots, guard cells are typically dumbbell-shaped, while in monocots, they are often bean-shaped.

**Conclusion:**
After analyzing all the statements, we find that all of them are true. However, if we were to identify a statement that could be considered misleading or less common, it might be Statement III, as it could imply that all stem hairs are multicellular, which is not always the case.

**Final Answer:**
None of the statements are outright false, but if we had to choose one that could be misleading, it would be Statement III.
