Removal of ring wood of tissue outside the vascular cambium from the tree trunk kills it because
1 water cannot move up
2 food does not travel down and roots become starved
3 shoot become starved
4 annual ring are not produced
Explanation:
Exp:B If a ring of tissue outside vascular cambium is cut then secondary phloem is removed sugars cannot travel from aerial photosynthesizing parts of plants to roots which are non photosynthetic. Consequently roots are killed and the plants dies.

Amphivasal vascular bundles are found in the stem of:
1 Beta
2 Cucurbita
3 Dracaena
4 Boerhaavia
Explanation:
Exp:C Amphivasal vascular bundles are found in the stem of Dracaena. A vascular bundle in which xylem encircles the central strand of phloem is known as amphivasal bundle, also called leptocentric bundle. Ex. Dracaena and Yucca.

Which of the following have living cytoplasm?
1 Vessels
2 Tracheids
3 Sclerenchyma
4 Companion cells
Explanation:
Exp:D The companion cells are thin walled elongated specialised parenchymatous cells which are closely associated with sieve tube elements through compound plasmodesmata.

Which of the following is a calcium carbonate?
1 Raffides
2 Druces
3 Cystolith
4 All of these
Explanation:
Exp:C Calcium corbonate is found in cystolith. The crystals of \(\mathrm{CaCO}_{3}\) called the cystolith and cells called lithocyte the crystals of calcium oxalate in the form of needles called Raphides and in the form star and druses.

Protoxylem lacunae occur in
1 cladodes
2 underground stems
3 vascular bundles of grass stem
4 climbers
Explanation:
Exp:C Protoxylem lacuanae occur in vascular bundles of grass stem. In the protoxylem of monocot vascular bundles some of the protoxylem cells disintegrate and form in to a lysogenous cavity called protoxylem lacunae. It stores water so it is also called water cavity.
