Answer the following question given this paragraph: 

Figure 26.8 illustrates the life cycle of a conifer. The sporophyte (2n) phase is the longest phase in the life of a gymnosperm. The gametophytes (1n)—microspores and megaspores—are reduced in size. It may take more than year between pollination and fertilization while the pollen tube grows towards the megasporocyte (2n), which undergoes meiosis into megaspores. The megaspores will mature into eggs (1n).


Q: The sporophyte phase is the longest phase in the life of what?

 Choices:

- echinoderm

- arthropod

- angiosperm

- gymnosperm

A:
gymnosperm
