Question 1.

Which of the below is a similarity between an angiosperm flower and a gymnosperm cone?

Both are composed of both mega- and microsporophylls

Both contain sporophylls as well as modified vegetative (non-fertile) leaves

Both contain the megagametophyte if megasporophylls are present, and in both the megagametophytes have well-developed archegonia

In both, the entire female haploid stage as well as the early embryonic diploid stage takes place within - or in association with - the megasporophylls

Both contain the megagametophyte if megasporophylls are present, but in both the megagametophyte has been reduced to seven cells or less.

Question 2.

How do elaiosome-producing plants (e.g. English violet) achieve seed dispersal?

They are wind dispersed

They are dispersed by ants

They get ingested by mammals

They cling to the fur of animals

The elaiosome acts as a life jacket for the seed and allows it to float

Question 3.

1. Describe how plants transport water from roots to leaves according to the cohesion-tension theory. You may support your answer with a drawing if you wish.

2. How does this differ from transport through the phloem?
