Questions with solutions
Q1 — The Tissues (Meristematic & Permanent) · easy · theory
The meristem responsible for increase in the LENGTH of the plant, present at root and shoot tips, is the:
A. Cork cambium
B. Lateral meristem
C. Intercalary meristem
D. Apical meristem ✓ Correct
Solution: Apical meristems at tips cause primary growth (elongation); lateral meristems cause girth (secondary) growth.
Q2 — The Tissues (Meristematic & Permanent) · easy · theory
A simple permanent tissue with living, thin-walled cells that stores food and performs photosynthesis is:
A. Collenchyma
B. Sclerenchyma
C. Parenchyma ✓ Correct
D. Xylem
Solution: Parenchyma is the basic living tissue; collenchyma gives flexible support and sclerenchyma rigid support.
Q3 — The Tissues (Meristematic & Permanent) · medium · theory
Collenchyma provides mechanical support to growing parts and is recognised by:
A. Cells with cellulose thickening at the corners ✓ Correct
B. Sieve plates
C. Uniformly thick lignified walls
D. Dead empty cells
Solution: Collenchyma cells are living with cellulose/pectin thickening at corners; sclerenchyma is dead with lignified walls.
Q4 — The Tissues (Meristematic & Permanent) · medium · theory
Which complex tissue conducts water and minerals and consists of tracheids, vessels, xylem fibres and xylem parenchyma?
A. Xylem ✓ Correct
B. Phloem
C. Epidermis
D. Collenchyma
Solution: Xylem conducts water upward; phloem (sieve tubes, companion cells, phloem parenchyma, fibres) conducts food.
Q5 — The Tissues (Meristematic & Permanent) · hard · theory
The intercalary meristem, present at the base of internodes/leaves in grasses, is a leftover of the:
A. Vascular cambium
B. Cork cambium
C. Apical meristem ✓ Correct
D. Ground tissue
Solution: Intercalary meristem is derived from apical meristem and allows regrowth after grazing/mowing in grasses.
Q6 — The Tissues (Meristematic & Permanent) · hard · theory
In the phloem of angiosperms, the living enucleate conducting cells are supported by adjacent ______ that control their activity:
A. Fibres — parenchyma
B. Sieve tube — companion cells ✓ Correct
C. Cork cells — cambium
D. Tracheids — vessels
Solution: Mature sieve tube elements lack a nucleus; their metabolism is regulated by the neighbouring companion cells.
