B Plants which are growing near water or in water is known as hydrophytes plants. - Root system and conducting tissue is poorly developed. There plants are spongy. - The plant body of these plants usually thin and delicate. Leaves are very thin membranous and the stem is slender and may remain covered with mucilage.

The interxylary phloem is found in the stem of:
1 Cucurbita
2 Salvia
3 Calotropis
4 None of these
Explanation:
C Interxylary phloem is strands or bands of phloem embedded within the secondary xylem of a stem or root of a plant that has a single vascular cambium. Initially vascular bundle behave normally of forming secondary xylem towards inner side and secondary phloem towards outerside. But later it produce small patches of secondary phloem towards inner side which are embedded in secondary xylem. There patches are termed as interxylary phloem.

Cotton fibre is basically a type of
1 trichome
2 scale
3 dried seed coat
4 non glandular hair
Explanation:
C Cotton fibres are the purest form of cellulose, nature's most abundant polymer, nearly \(90 \%\) of the cotton fibres are cellulose. Cotton fibre is obtained from the seed part of the flower. - The raw fibres are separated from the seeds by a process known as ginning.

How does pruning help in making the hedge dense?
1 It induces the differentiation of new shoots from the rootstock
2 It frees axillary buds from apical dominance
3 The apical shoot grows faster after pruning
4 It releases wound hormones
Explanation:
B Pruning help in making the hedge dense as it frees the axillary buds from apical dominance. Apical buds produce high concentration of hormone auxin which inhibits the growth of lateral buds. When the apical buds are removed by pruning, the lateral bud grow. This produces dense bushy growth.
