please choose the correct answer Question 27 1 points Saving Which statement is true? a. Both gymnosperms and angiosperms produce seeds on the scales of cones, but angiosperms have flowers. b. Gymnosperms rely on animals to carry pollen from the female gametophyte to the male gametophyte, while angiosperms rely on wind. in gymnosperms, male gametophytes and female gametophytes are produced in different structures, while in angiosperms they are usually produced in the same structure. d. Gymnosperms require water for sperm...
PLEASE HELP WITH ALL QUESTIONS Which of the following statements is FALSE? Seeds include a source of nourishment of the developing embryo. A selective disadvantage of seeds is that the seed coat is highly vulnerable to invasion by fungi and bacteria. Most plants that produce seeds also produce nonflagellated sperm. Many seeds can remain dormant during long periods of drought or low temperatures. 5. In seed plants, fertilization can occur without the presence of water. 2 The world's tallest plants...
1. Which of the outcomes would occur if a moss had a mutation that inhibited the production of sporopollenin? The spores would dry out more quickly. The likelihood of outcrossing would decrease. Spores would not be released from the sporangia. The moss would not be able to produce pollen. Sperm would not be able to reach eggs for fertilization. 2. Which of the qualities is a major difference between all spore-dispersing and seed-dispersing plants? Select all that apply. The gametophytes...
6. Which is not a characteristic of fungi? A. Most are single celled B. It is a saprophyte D. It lives moist areas E. All the above are characteristics of the fungi C. It is a decomposer 7. Why is the relationship between most mycorhizal fungi and their host plants considered mutualistic? A. They live in close physical association. B. Both species benefit from the association. C. The host plant cannot live without the mycorhizae. D. The mycorhizae cannot live...
1. A student uses iodine to visualize cells under the light microscope. Iodine stains starch deep blue and glycogen granules dark brown. Observation of the cells reveals the presence of cell walls, dark brown granules, mitochondria, and a prominent nucleus. If the chemical composition of the cell wall is determined, which of the following molecules would MOST likely be the major constituent? A. cellulose B. chitin C. lignin D. peptidoglycan 2. Which of the following statements is the MOST compelling...
1. When you look at a pine or maple tree, the plant you see is a _____. 2. The Brazil nut tree, Bertholletia excels (n = 17), is native to tropical rain forests of South America. It is a hardwood tree that can grow to over 50 meters tall, is a source of high-quality lumber, and is a favorite nesting site for harpy eagles. As the rainy season ends, tough-walled fruits, each containing 8-25 seeds (Brazil nuts), fall to the...

The first land plants share a most recent common ancestor with a group of aquatic organisms that lived in the littoral zone known as: A) charophyceans; B) chlorophytes; C) catphytes; D) coanocytes; E) cycadophytes 30. Which of the following is true for organisms with zygotic meiosis? A) The gametes are produced from haploid...

IV. Fill In The Blanks (2 pts each). The answers are among the terms listed at the bottom of the page. [Total = 30 points There are three different life cycle patterns known as Gametic Meiosis, Zygotic Melosis and Sporic Meiosis. All animals undergo 39. Meiosis, whereas all terrestrial plants undergo 40. Meiosis. In lily seeds, the tissue that provides nutrition for the developing embryo is called the , whereas in pine seeds, the tissue that provides nutrition for developing...
In ferns, both the gametophyte and sporophyte are physiologically capable of surviving on their own. Which of the following are reasonable hypotheses for why vascular tissues are present only in the sporophyte generation? Select all that apply. There is no advantage for the gametophyte to grow tall, because fern gametophytes typically produce only male or female gametes at any one time There is no advantage for the gametophyte to grow tall, because gametes must be produced near the ground where...
