Raphides are crystals of
1 calcium carbonate
2 calcium oxalate
3 magnesium carbonate
4 magnesium oxalate
Explanation:
: Calcium oxalate crystal is present in raphides of almost all the plant organ and is particularly common in storage organs, pith and cortical tissue. The shape of the crystals called raphides are found in aroids e.g. Colocasia, Amorphophallus impatieus and many aquatic plant e.g. Pistia, Eichornia.

Leptocentric (amphivasal) vascular bundles, (in which the whole phloem is enclosed by xylem) are characteristic feature of
1 Dracaena and Yucca-Monocot
2 Dracaena and Cucurbita-Monocot
3 Ficus and Shorea-Dicot
4 Xanthium and Acacia-Dicot
Explanation:
: Leptocentric (amphivasal) vascular bundles is one type of concentric bundles. In that type of bundles xylem tissue surrounds the phloem tissue. It is found in Dracaena, yucca and other monocots and some dicots also. Another type concentric bundle is amphicribal where phloem surrounds xylems and it is found in ferns.

Middle lamella is present
1 inside the secondary wall
2 inside the primary wall
3 outside the primary wall
4 in between secondary and tertiary walls
Explanation:
: The middle lamella is presents outside the primary wall. Calcium and magnesium pectates form the middle lamella. In a mature plant cell it is the outermost layer of the cell wall. In such case the two adjacent primary wall and the middle lamella perhaps the first layer of the secondary wall of each cell may be called a compound middle lamella.

What happens in plants during vascularisation?
1 Differentiation of procambium, formation of primary phloem followed by formation of primary xylem
2 Differentiation of procambium followed by the formation of primary phloem and xylem simultaneously
3 Formation of procambium, primary phloem and xylem simultaneously
4 Differentiation of procambium followed by the formation of secondary xylem
Explanation:
Exp:B Vascularization in plants occurs through differentiation of procambium followed by the development of xylem and phloem. All procambial cells appears to differentiate into vascular tissues during primary growth.
