1 Chapter 24 Reproduction of Seed Plants Section 24 1 Reproduction With Cones and Flowers (pages ) This section describes the reproductive structures of gymnosperms and angiosperms. It also explains how pollination and fertilization differ between angiosperms and gymnosperms. Alternation of Generations (page 609) 1. Circle the letter of each sentence that is true about alternation of generations in plants. a. In all plants, the sporophyte generation is diploid. b. The gametophyte in seed plants is hidden within the sporophyte plant. c. The recognizable part of a seed-bearing plant is the gametophyte. d. In all plants, the gametophyte generation is haploid. 2. An important trend in plant evolution is the reduction in the size of the gametophyte. 3. Where are the gametophytes found in gymnosperms and angiosperms? They are found inside the cones in gymnosperms and inside flowers in angiosperms. Life Cycle of Gymnosperms (pages ) 4. Reproduction in gymnosperms takes place in cones. 5. Circle the letter of what produces cones in gymnosperms. a. mature sporophyte c. pine trees b. mature gametophyte d. pollen seeds 6. What kind of cone produces male gametophytes? Pollen cones 7. The male gametophytes of gymnosperms are called pollen grains. 8. Circle the letter of each sentence that is true about seed cones. a. They produce pollen grains. b. They produce female gametophytes. c. They have two ovules at the base of each scale. d. They are generally much larger than pollen cones. 9. Is the following sentence true or false? Each mature female gametophyte contains hundreds of egg cells ready for fertilization. false 10. How long does the gymnosperm life cycle typically take to complete? It typically takes two years.

2 Name Class Date 11. In the gymnosperm life cycle, how do the pollen grains reach the female cones? The pollen grains are released by the male cones, and some are carried to the female cones by the wind. 12. What ensures that pollen grains stay on the scales of a female cone? called pollination drop, ensures that the pollen grains stay. A sticky material, 13. A structure grown by a pollen grain that contains two sperm nuclei is called a(an) pollen tube. 14. What happens to the two sperm cells once the pollen tube reaches the female gametophyte? One sperm nucleus disintegrates, and the other fertilizes the egg contained in the female gametophyte. 15. Circle the letter of what a gymnosperm embryo can be called. a. mature gametophyte b. new sporophyte c. mature sporophyte d. new gametophyte 16. What are the three generations of the gymnosperm life cycle that are contained in a gymnosperm seed? The outer seed coat is part of the old sporophyte generation, the haploid cells surrounding the embryo are part of the female gametophyte, and the embryo is the new sporophyte plant. Structure of Flowers (pages ) 17. What are the four kinds of specialized leaves that compose a flower? a. Sepals b. Petals c. Stamens d. Carpels

3 Match the floral part with its description. Floral Part Description d 18. Sepals a. Stalk with the stigma at the top i 19. Petals b. Structures where male gametophytes are produced h 20. Stamen c. Flower part that contains one or more ovules e 21. Filament d. Outermost, green floral parts b 22. Anthers e. Long, thin structure that supports an anther f 23. Carpels f. Innermost floral parts that produce female gametophytes c 24. Ovary g. Sticky, top portion of style a 25. Style h. Male structure made up of an anther and a filament g 26. Stigma i. Brightly colored parts just inside the sepals 27. Label the parts of the flower on the illustration. Petal Stigma Style Anther Filament Stamen Style Ovules Ovary 28. What is a pistil? It is a reproductive structure formed from the fusion of several carpels. 29. What are the separate male and female flowers on a corn plant? The tassel is a flower that produces male gametophytes, and the silk is the style of a flower that contains the female gametophyte.

4 Name Class Date Life Cycle of Angiosperms (pages ) 30. Where does reproduction in angiosperms take place? It takes place within the flower. 31. Inside the anthers, each cell undergoes meiosis and produces haploid cells called megaspores. 32. In angiosperms, the pollen grain is the entire male gametophyte. 33. The female gametophyte of an angiosperm, contained within the ovary, is called the embryo sac. 34. Circle the letter of each sentence that is true about the life cycle of angiosperms. a. The cycle begins when the mature sporophyte produces flowers. b. A pollen grain stops growing when it is released from the stigma. c. The female gametophyte develops in the ovule. d. The egg nucleus is one of the eight nuclei in the embryo sac. Pollination (page 615) 35. How are most gymnosperms pollinated? Most are pollinated by the wind. 36. How are most angiosperms pollinated? Most are pollinated by animals. 37. What are three kinds of animals that pollinate angiosperms? Insects, birds, and mammals pollinate angiosperms. Fertilization in Angiosperms (page 616) 38. What are the two distinct fertilizations that take place in angiosperms? a. One of the sperm nuclei fuses with the egg nucleus to produce a diploid zygote cell. b. The other sperm nucleus fuses with two other nuclei in the embryo sac to form a triploid cell. 39. The food-rich tissue that nourishes a seedling as it grows is known as endosperm. 40. Why is fertilization in angiosperms known as double fertilization? Two distinct fertilization events take place between the male and female gametophytes.

5 41. Complete the flowchart about the life cycle of angiosperms. Inside the anthers, each cell undergoes meiosis to produce megaspores. Each megaspore becomes a(an) pollen grain. The nucleus of each pollen grain produces two haploid nuclei. The pollen grain lands on a stigma and begins to grow a(an) pollen tube that eventually reaches the ovary and enters the ovule. One of the sperm nuclei fuses with the egg nucleus to produce a(an) zygote, and the other sperm nuclei fuses with two other nuclei to form a cell that grows into the endosperm. Reading Skill Practice Outlining is a way you can help yourself understand better and remember what you have read. Write an outline for Section 24 1, Reproduction With Cones and Flowers. In your outline, use the blue headings for the first level and the green subheadings for the second level. Then, list the details that support, or back up, the main ideas. Students should use the section s six blue headings for the first level of their outline and use the green headings where appropriate. Supporting details should include the boldface vocabulary terms and key concepts.

6 Name Class Date Section 24 2 Seed Development and Germination (pages ) This section explains how seeds develop and are dispersed. It also describes factors that influence the dormancy and germination of seeds. Seed and Fruit Development (page 618) 1. What is a fruit? It is a ripened ovary that contains angiosperm seeds. 2. What happens as angiosperm seeds mature after fertilization is complete? The ovary walls thicken to form a fruit that encloses the developing seeds. 3. The outer layer of the seed that protects the embryo and its food supply is called a(an) seed coat. 4. Is the following sentence true or false? Both cucumbers and tomatoes are fruits. true 5. Circle the letter of each sentence that is true about fruits. a. As seeds mature, the ovary walls thicken to form a fruit. b. Fruits can carry one seed or several seeds. c. A fruit is a ripened ovary that encloses a seed or seeds. d. The inner wall of the ovary never touches the seed. Seed Dispersal (page 619) 6. Why are seeds that are dispersed by animals typically contained in fleshy, nutritious fruits? These fruits provide nutrition for the animal and also help the plant disperse its seeds. 7. Circle the letter of why seeds dispersed by animals are covered with tough coatings. a. The seeds need to be able to float on water. b. The coatings enable the seeds to pass through an animal unharmed. c. The seeds need to be digested by the animal that eats them. d. The coatings prevent the seeds from being eaten by animals. 8. Why are seeds dispersed by wind or water typically lightweight? Being lightweight allows the seeds to be carried in the air or to float on the surface of the water. 9. How are the seeds of ash and maple trees dispersed long distances from the parent plants? Their seeds are encased in winglike structures that spin and twirl as they are released, helping them glide considerable distances.

7 10. What adaptation does a coconut seed have that helps its dispersal? The seed contains a liquid endosperm layer that makes a coconut buoyant enough to float in sea water within its protective coating for many weeks. Seed Dormancy (page 620) 11. What is dormancy? It is a period in which the plant embryo is alive but not growing. 12. What are two environmental factors that can cause a seed to end dormancy and germinate? a. Temperature b. Moisture 13. What are two purposes served by seed dormancy? a. It can allow for long-distance dispersal. b. It can allow seeds to germinate under ideal growth conditions. 14. Is the following sentence true or false? Some pine tree seeds remain dormant until the high temperatures generated by a forest fire cause cones to open and release the seeds. true Seed Germination (page 621) 15. What is seed germination? Seed germination is the early growth stage of the plant embryo. 16. Complete the flowchart about seed germination. When a seed germinates, it absorbs water. The water causes the endosperm to swell, which cracks open the seed coat. Through the cracked seed coat, the young root begins to grow. 17. Circle the letter of each sentence that is true about seed germination. a. In some dicots, the cotyledons protect the first foliage leaves. b. In most monocots, the cotyledon remains within the seed. c. In some dicots, the cotyledons remain below the soil and provide food for the seedling. d. In most monocots, the cotyledon emerges above ground to protect the leaves.
