Seeds and pollen grains are key adaptations for life on land. These adaptations relate to reproductive success and survival advantages. The following questions require you to explain some of these adaptations.
A. Contrast sperm delivery in seedless plants with sperm delivery in seed plants. (5-6 sentence)
B. Discuss at least one feature of seed plants that contributed to their success on land in contrast with seedless plants. (2-3 sentences)
C. Flowering plants (Magnoliophyta) are the most successful of all plant groups in terms of their species diversity and ubiquity across habitat types. Climate warming is causing shifts in the timing of life history events for many species. Discuss how climate warming may influence reproductive strategies employed by flowering plants. (2-3 sentence)
Which of these is a condition that makes flowers invariably autogamous ?
(a) Dioecy
(b) Self incompatibility
(c) Cleistogamy
(d) Xenogamy
Which of the following statements about the haplodiplontic life cycle of land plants is/are TRUE?
A During the sporophyte stage, sporangia house diploid mother cells that will eventually undergo meiosis.
B Sperm develop from mitosis in the archegonium.
C Spores grow by mitosis into mature haploid gametophytes.
D The gametophytic stage begins with a diploid spore.
EA and C are both true.
