12) Why do you say that fertilization in seed plants is independent of water? A) Spermatid cells are not necessary for fertilization to occur in seed plants. B) Seed plants use pollen instead of spermatid cells for fertilization. C) Spermatid cells are carried by pollen grains. D) Which spermatid cells in seed plants are capable of resisting desiccation indefinitely.

Based on this evidence, is it likely that burdock would reproduce as much if it didn’t have specially structured seeds? (a) it is most likely that it would still reproduce, but the offspring would probably be located much closer together (b) there is not enough information to speculate about how well burdock plants reproduce (c) no, there wouldn’t be as much burdock without its special structures (d) Yes, burdock would spread just as well regardless of the design of its seed pods

Which of the following statements is accurate? a) All plants have identical sporangia, all producing the same type of spores b) Plants have an embryo that is protected inside (and nourished by) the gametophyte c) Gametangia produce gametes by meiosis whereas sporangia produce spores by mitosis d) Gametangia always produce haploid gametes whereas sporangia produce diploid spores e) Gametangia are multicellular structures whereas sporangia are unicellular structures

Insects are attracted to the flower of plants. When they rub against parts of the plant, they carry genetic material to other plants, allowing plants to produce seeds. This is an example of: O a) protection O b) digestion c) hygiene d) reproduction

In a typical angiosperm, what is the sequence of structures encountered by the tip of a growing pollen tube on its way to the egg?     ovary → style → stigma     stigma → style → ovary     ovary→ stigma→ style     stigma→ ovary → style

Name the female reproductive organ of a flower bearing ovules.

The drooping, bell-like flower Aquilegia canadensis is adapted for cross-pollination. However, if the plant has not been pollinated previously, self-pollination can occur. However, if cross pollination occurs after self-pollination takes place, the pollen from cross pollination reaches the style before the pollen from self-pollination. Using course concepts and vocabulary 1) Provide a reasoning for this phenomenon. 2) Would this adaptation for reproduction be beneficial for the plant?

4. A) Identify which type of light (Red or Far-Red) simulates seed germination. B) Identify which type of light (Red or Far-Red) inhibits seed germination. C) If a group of seeds was exposed to the following light sequence: red → far-red →red → far-red → red → darkness, would seed germination be inhibited or simulated? Please answer in order and label them.

A disease spreads that only effects the haploid cells of a plant, killing them. What would happen to an angiosperm? |- it would not be able to reproduce Il - the photosynthetic stage of the organism would die III - the sporophyte stage would be effected IV- organs containing sperm and egg would be effected O a) I and IV O b) II OC) I, II, III and IV O d) Il and II
