What is the advantage of a reduced gametophyte in seed plants? a) The gametophyte section of the plant’s life cycle is reduced and therefore the cycle occurs faster. b) The gametophytes of seed plants develop within the walls of spores which provide protection and nutrients. c) The gametophyte is free-living and does not depend on the sporophyte for nutrition. d) The gametophytes are macroscopic. 3.

A, 2.B, 3.D, 4.D, 5.B, 6.D, 7.A, 8.B, 9.C, 10.A Short Answer: Answer one of the following a) Gymnosperms include four phyla. List and give a short summary of each phylum. b) List, define and compare the two main groups of angiosperms. Answers: a) There are ten plant phyla in which four phyla are gymnosperms. These phyla are cycadophyta, ginkgophyta, gnephyta and coniferophyta. Firstly phylum Cycadophyta is the second largest after conifers and it is characterised with large cones and palm like leaves. Another phylum is Ginkgophyta which has only one species called Ginkgo biloba. Ginkgo biloba has fern like leaves that turn gold in autumn. Then phylum Gnetphyta which has plants that are called gnetophytes, and they consist of 3 genera: Gnetum, Ephedra and Welwitschia. Some of these species live in deserts and some are tropical. Finally, phylum Coniferophyta and it is the largest of gymnosperms phyla. This phylum has many large trees like cypresses and red woods. Most conifers are evergreen. b) The two main groups of angiosperms are monocots and eudicots. Monocots are angiosperms that have one cotyledons or seed leaves. The leaves of monocots have parallel veins. Their vascular tissues are scattered and their roots are fibrous. Monocots’ pollen grains have only one opening and their floral organ are in multiples of 3. Eudicots are angiosperms that have two cotyledons or seed leaves. The leaves of eudicots have netlike veins. Their vascular tissue is usually arranged in a ring and they have taproots. Eudicots’ pollen grains have 3 openings and their floral organs are in multiples of four or five.
