Vascular bundles, in which phloem is found on both sides of xylem are called
1 collateral
2 bicollateral
3 radial
4 amphicribral
Explanation:
Exp:B Bicolateral vascular bundle have xylem and phloem present on the same radius and phloem is found in both the side of xylem. In vascular bundle plants are made up of conducting tissue of the xylem and the phloem. In collateral vascular bundle xylem and phloem are present on the same radius. The phloem is present on the outer side of xylem.

The cells without nuclei are present in :
1 vascular cambium
2 root hair
3 companion cell
4 members of sieve tube
Explanation:
Exp:D The cell without nuclei are present in member of sieve tube elements are important component of phloem. They are devoid of a nucleus at maturity. This is normally associated with one or more nucleated companion cells to which they are connected by plasmodesmata.

Which is a useful product of epidermal origin?
1 Saffron
2 Cotton fibres
3 Clove
4 Jute
Explanation:
Exp:B Cotton fibres is chiefly composed of epidermal hairs of seeds and present on the surface of seeds of Gossypium species. These are made up cellulose only and may be of two type i.e extractable and non extractable fluffy fuzz. Cotton fibres are mainly used for textiles celluloid, rayon and paper pulp.

When the vascular cambium is present between the xylem and phloem, then the vascular bundle is called,
1 Closed
2 Exarch
3 Open
4 Endarch
Explanation:
Exp:C In gymnosperms and dicot stems a strip of vascular cambium occurs between phloem and xylem of each vascular bundles. It is called intrafascicular cambium. This strip of vascular cambium later produces secondary tissues. Such vascular bundles are described as open vascular bundle.
