Questions with solutions
Q1 — The Tissue Systems · easy · theory
The epidermal tissue system includes the epidermis, stomata and:
A. Epidermal appendages (trichomes and root hairs) ✓ Correct
B. Vascular bundles
C. Pith
D. Cambium
Solution: The epidermal system covers the plant and includes stomata and appendages (root hairs, trichomes).
Q2 — The Tissue Systems · easy · theory
Stomata are guarded by two ______ that regulate transpiration and gas exchange:
A. Cortex cells
B. Guard cells ✓ Correct
C. Companion cells
D. Subsidiary cells only
Solution: Guard cells (bean-shaped in dicots, dumbbell in grasses) open/close the stomatal pore.
Q3 — The Tissue Systems · medium · theory
The ground tissue system comprises all tissues EXCEPT the:
A. Cortex
B. Pith
C. Mesophyll
D. Epidermal and vascular tissues ✓ Correct
Solution: Ground tissue = everything except epidermis and vascular bundles: cortex, pericycle, pith, mesophyll etc.
Q4 — The Tissue Systems · medium · theory
In a vascular bundle where xylem and phloem lie on the same radius with phloem outside xylem, the bundle is:
A. Bicollateral only
B. Conjoint and collateral ✓ Correct
C. Radial
D. Concentric
Solution: Conjoint collateral bundles (xylem inside, phloem outside) are typical of stems; radial bundles (alternate) occur in roots.
Q5 — The Tissue Systems · hard · theory
In roots, the xylem and phloem are arranged on ______ radii, making the bundle:
A. Different (alternate); radial ✓ Correct
B. Same; bicollateral
C. Concentric; amphivasal
D. The same; collateral
Solution: Root vascular bundles are radial — xylem and phloem lie on alternate radii, a key root-identifying feature.
Q6 — The Tissue Systems · hard · theory
A concentric vascular bundle in which phloem surrounds a central xylem is termed:
A. Amphicribral (leptocentric) ✓ Correct
B. Amphivasal (hadrocentric)
C. Radial
D. Collateral
Solution: Amphicribral = phloem around xylem (ferns); amphivasal = xylem around phloem (some monocots like Dracaena).
