Final Answer:

17: B 16: C 15: D 13: B 12: True 11: False 10: False 9: D 8: B 7: A 6: False 5: B 3: True 4: True 1: False 2: False

Explanation:

17: The zygote develops into a protonema in the life cycle of B. Chlamydomonas.

16: The following is not found in the liverworts: C. sporophyte consists of foot, seta and sporangium.

15: In Selaginella, the megasporangium undergoes meiosis to produce D. 1 megaspore.

13: A primitive vascular plant without roots and leaves is B. Psilotum.

12: All nonvascular plants have protonema, rhizoid and a whiplash biflagellated, anterior sperm. This is true.

11: Double fertilization and heterospory does not occur in all seed plants. This is false. Double fertilization only occurs in angiosperms.

10: The cell wall of zygote in Chlamydomonas is made up of false. It is made up of cellulose and pectin.

9: All are correct about liverworts except: D. rhizoids are unicellular. Rhizoids of liverworts are multicellular.

8: Heterospory is an advanced evolutionary feature that occurs in B. Selaginella.

7: Cyanobacteria can be divided based on their form. Gleocapsa represent an example of A. Filament.

6: Three fused sporangia. Fertile axes produce tri-lobed structure called synangium,found in false. Synangium is found in pteridophytes, not bryophytes.

5: In angiosperms, the embryonic sporophyte is nourished by B. diploid endosperm.

3: Young pine stem have an ectophloic siphonostele with discrete vascular bundles. This is true.

4: Lipid bodies in Cyanobacteria are high energy-yield metabolic product. This is true.

1: Megastrobili of pine are borne on short lateral branches of terminal buds. This is false. Megastrobili of pine are borne on the upper side of the main axis of the cone.

2: During phragmoplast, spindle fibres arranged in parallel with the equator. This is false. Spindle fibres are arranged perpendicular to the equator during phragmoplast.
