C. Formation of sieve tubes with dense cytoplasm, thin walls,
D. Presence of thin parenchymatous and no vacuoles. This helps in
walls growth.

The specialization of xylem vessels
and sieve tubes ensures efficiency in
transport. Squamous epithelium,
though responsible for gas
exchange, is not specialized for
nutrient transport.
Ques 17) Explanation:
Meristematic cells lack large
vacuoles because they are actively
dividing cells and do not store
nutrients. Their cytoplasm is dense,
and the absence of vacuoles
provides space for rapid division.
Thin walls and actively dividing cells
are characteristics of meristematic
tissue.
Ques 18) Explanation: Adipose
tissue is a type of connective tissue
specialized for fat storage, providing
insulation and cushioning to the
body. Cartilage offers structural
support, areolar tissue connects
various tissues, and bone provides a
rigid framework but does not store
fat or insulate.
Ques 20) Explanation: Lignin
deposition in xylem vessels makes
their walls rigid and capable of
withstanding the high pressure
generated during water conduction.
While pits allow lateral movement of
water, they do not contribute to
structural strength.
