Solved Questions

Q1. Collenchyma provides:

Flexibility and mechanical support
Food storage
Water transport
Gas exchange

Difficulty: Easy · Topic: Plant Tissues

Solution

Collenchyma: living cells with thickened corners (pectin/cellulose). Provides flexibility and mechanical support to growing organs.

Q2. Annual rings in trees are formed by:

cambium
primary xylem
phloem
secondary xylem

Difficulty: Easy · Topic: Anatomy of Plants

Solution

secondary xylem.

Q3. Sclerenchyma provides:

mechanical strength (dead at maturity)
food storage
flexibility
transport

Difficulty: Easy · Topic: Anatomy of Plants

Solution

mechanical strength (dead at maturity).

Q4. Parenchyma is involved in:

mechanical support only
transport only
storage, photosynthesis, aeration
protection only

Difficulty: Easy · Topic: Anatomy of Plants

Solution

storage, photosynthesis, aeration.

Q5. Vascular cambium produces:

cork
epidermis
primary xylem
secondary xylem and phloem

Difficulty: Easy · Topic: Anatomy of Plants

Solution

secondary xylem and phloem.

Q6. Cork cambium (phellogen) produces:

epidermis
xylem
phellem (cork) and phelloderm
phloem

Difficulty: Easy · Topic: Anatomy of Plants

Solution

phellem (cork) and phelloderm.

Q7. Heartwood is:

dead, dark, central wood
bark
pith
living, outer wood

Difficulty: Easy · Topic: Anatomy of Plants

Solution

dead, dark, central wood.

Q8. Sapwood is:

dead central wood
bark
pith
living, lighter, outer wood

Difficulty: Easy · Topic: Anatomy of Plants

Solution

living, lighter, outer wood.

Q9. Trichomes are:

epidermal outgrowths (hairs)
lenticels
stomata
root hairs

Difficulty: Easy · Topic: Anatomy of Plants

Solution

epidermal outgrowths (hairs).

Q10. Lenticels are:

pores in bark for gas exchange
stomata
root hairs
trichomes

Difficulty: Easy · Topic: Anatomy of Plants

Solution

pores in bark for gas exchange.

Q11. Pith is the:

vascular tissue
central ground tissue
outer cortex
epidermis

Difficulty: Easy · Topic: Anatomy of Plants

Solution

central ground tissue.

Q12. Cortex is the tissue between:

phloem and bark
epidermis and stele
pith and xylem
xylem and phloem

Difficulty: Easy · Topic: Anatomy of Plants

Solution

epidermis and stele.

Q13. Casparian strips are found in the:

Cortex
Endodermis
Pericycle
Epidermis

Difficulty: Easy-Medium · Topic: Root Anatomy

Solution

Casparian strips are thickenings of suberin/lignin in the endodermis cell walls, regulating water/mineral flow into the stele.

Q14. Vascular bundles in monocot stems are:

Open
Closed
Both open and closed
Absent

Difficulty: Easy-Medium · Topic: Stem Anatomy

Solution

Monocot stem vascular bundles are closed (no cambium between xylem and phloem), so no secondary growth.

Q15. Meristematic tissue is found at:

pith
growing tips
mature regions
bark

Difficulty: Easy-Medium · Topic: Anatomy of Plants

Solution

growing tips.

Q16. Xylem transports:

hormones
food downward
water and minerals upward
gases

Difficulty: Easy-Medium · Topic: Anatomy of Plants

Solution

water and minerals upward.

Q17. Phloem transports:

organic food (sucrose)
minerals only
gases
water

Difficulty: Easy-Medium · Topic: Anatomy of Plants

Solution

organic food (sucrose).

Q18. Stomata regulate:

gas exchange and transpiration
photosynthesis only
growth
respiration only

Difficulty: Easy-Medium · Topic: Anatomy of Plants

Solution

gas exchange and transpiration.

Q19. Cork cambium produces:

bark (periderm)
flowers
vascular tissue
leaves

Difficulty: Easy-Medium · Topic: Anatomy of Plants

Solution

bark (periderm).
