50. Option D is correct. Gnetophyta group of gymnosperm is different from all other groups of gymnosperms because of presence of efficient water conducting system in gnetophyta.
51. Option B is correct. Onions are monocots rest all are dicots
52. Option E is correct. The hypae of primary mycelium is monokaryotic and secondary mycelium contains dikaryotic hypae.
53. Option A is correct. There are two types of vascular elements found in plants, Xylem and phloem. Xylem transport water and nutrients from root to the leaves and phloem transport foods from leaves to other parts of the plants. Sap is water based solution containing high amount of dissolved sugar.
54. Option B is correct. Glameromycetes is coenocytic (hyphae without septa) and produce asexually with blastopores.
55. Option B is correct. Ovule develops into seed and ovule wall develops into seed coat.
