Which of the following incorrectly pairs a sporophyte embryo with its food source? *
A. Moss embryo-archegonium and gametophyte plant
B. Fern embryo-female sporophyte surrounding archegonium
C. Pine embryo-female gametophyte tissue in nucellus
D. Corn embryo-3N endosperm tissue in seed
Which of the following statements regarding plants is false?a. Meiosis within anthers produces spores that develop intopollen.b. Meiosis within ovules produces spores that develop into anembryo sac.c. The male gametophyte is a pollen grain, and the femalegametophyte is an embryo sac.d. Meiosis directly produces sperm and egg cells in plants
Plants that are dioecious are best described as having:
-archegonia and antheridia on separate gametophytes.
-archegonia and antheridia on separate sporophytes.
-archegonia and antheridia on the same gametophyte
-the ability to make pollen grains via archegonia
-ovules contained within antheridia

- Which of the following comparisons between the moss life cycle and fern life cycle are correct? A) Mosses have flagellated sperm that need water to reach the female gamete, while the sperm of ferns are unflagellated and are not dependent on water.B) The sporophyte generation is smaller than the gametophyte generation in mosses, but the sporophyte generation is much larger than the gametophyte generation in ferns.C) The spores are produced in capsules on stalks in mosses but in small structures called sori on the underside of leaves in ferns.D) The gametes are produced in gametangia in mosses but in specialized structures on the underside of leaves in ferns.E) Both kinds of plants depend on wind for dispersal of spores.arrow_forwardSeedless vascular plants must reproduce when conditions are wet because their sperm must_______________ .

Seed cone allows the entry of wind- borne pollen grains, once enclosed pollen grain will slowly develop pollen tube 2. Small seeds can be carried away by wind and large seeds are dispersed by animals 3. In spring or in a windy day, thousands of pollen grains will disperse. 4. Seeds contains three tissues; embryo, seed coat and gametophyte 5. Conifers produce two types of spores; pollen cone that contains male gametophyte and a seed cone containing enclosing archegonia 6. Flagellated sperm will release to fertilize the egg and eventually develop into a tiny embryo 7. Once germinated, conifer establish first a good rooting system for protection and seeking nourishment.arrow_forward
- 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.
