Explanation:
Wolffia is one of the smallest flowering plants on the earth and wolffia is an example for aquatic plants and resembles corn meal specks that float on water. - In the angiosperms, the seeds are surrounded by one of two integuments which develop into a seed coat that is usually hard. - Double fertilization is a characteristic feature of angiosperms. In this process of double fertilization both diploid zygote and triploid endosperm are formed. Double fertilization is complex process where out of two sperm cells, one fuses with the egg cell and the other fuses with two polar nuclei which result in a diploid (2n) zygote and a triploid (3n) primary endosperm nucleus respectively.

The angiosperm showing symbiotic association with blue green algae is
1 lens
2 cyamopsis
3 trifolium
4 none of these
Explanation:
Clover or trefoil are common names for plants of the genus trifolium, flowering plants in the lagume or pea family fabaceae originating in Europe. It shows symbiotic association with blue- green algae. Cyamopsis is also a genus of family fabaceae in its unmodified form, this food additive is used as a thickener in a large variety of food products.

Seeds possess spongy aril in
1 Eichhornia
2 Potamogeton
3 Sagittaria
4 Nymphaea
Explanation:
Seeds possess spongy aril in Nymphaea. It is genus of hardy and tender aquatic plants in the family Nymphaeaceae. The fruit dehisces by the swelling of mucilage surrounding the seeds.

From evolutionary point of view, tracheids and sieve cells are more primitive than tracheae and sieve tubes respectively. The angiosperms have
1 tracheae and sieve tubes
2 tracheids, tracheae and sieve tubes
3 tracheae, sieve cells and sieve tubes
4 tracheids, tracheae and sieve cells
Explanation:
In angiosperm, xylem consists of tracheids, vessels or tracheae, xylem fibre and xylem parenchyma. Sieve cells and tracheids are also primitive structure which are present in gymnosperms. Tracheae are absent in Pteridophytes and Gymnosperm. In angiospermic phloem sieve elements are sieve tubes while, in gymnosperms and pteridophytes sieve cells are found.
