Question 4

The Gnetophytes are the most likely progenitors of flowering plants. Which feature is common to both the Gnetophytes and Magnoliophytes and found in no other taxon?

Accepted Answer

A)  Double fertilisation in which one sperm nucleus fuses with the egg nucleus while the other fuses with the nucleus of a sterile neck canal cell of the archegonium, producing two embryos. 
B)  The complete enclosure of the ovule in bracts or bracteoles to form flowers. 
C)  Water-conducting cells in a woody xylem. 
D)  Vessel members with perforation plates at the ends of the cells, as well as tracheids. 
E)  Phloem sieve elements with companion cells.

Question 5

Cycads

Accepted Answer

A)  are wind-pollinated. 
B)  have sperm with a single whiplash flagellum and require free water to effect fertilisation.

D)  have development of a root system. 
E)  have sperm that are multiflagellated.
