Question 4 How is angiosperm fertilization different than in gymnosperms? a. Angiosperms are the only plants to produce seeds after fertilization takes place. b. In angiosperms, the female gametophyte is present on bracts. c. In angiosperms, a sperm fuses with an egg to produce a zygote. d. Unlike other plants, angiosperms require water for fertilization to take place. e. Two fertilization events take place in angiosperms, producing a zygote and endosperm.

Female cone In the female cones, _(haploid or diploid)_ female gametophytes are produced. This female will contain an egg. 3. Fertilization. When the sperm fertilizes the egg, a _(haploid or diploid)_ embryo is produced. This embryo is the new _(sporophyte or gametophyte)_generation. 4.

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...

Flowers confer all of the following benefits EXCEPT: Question 7 options: more targeted/specific pollen dispersal than reliance on wind increased photosynthetic rate in flower petals fruit production encourages animals to disperse seeds animals can help bring angiosperm egg and sperm together The advantage of _________ in gymnosperms is _________. Question 6 options: seeds; dispersing haploid cells through the water phloem; making it possible for roots to grow underground flowers; attracting pollinators to carry out fertilization xylem; not needing leaves to...

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...

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...
