- In an angiosperm life cycle, sexual reproduction includes: meiosis within the male gametophyte to produce sperm. meiosis within the female gametophyte to produce eggs. meiosis within the ovary to produce megaspores. fertilization leading to development of microspores. fertilization leading to development of megaspores.Which of the following traits characterizes gymnosperms? a. The plants carry exposed seeds on modified leaves. b. Reproductive structures are located in a flower. c. After fertilization, the ovary thickens and forms a fruit. d. The gametophyte is longest phase of the life cycle.In flowers, the structures that produce male gametophytes are called _______ ;the strcutures that produce female gametophytes are called _______ . a. pollen grains; flowers c. anthers; stigma b. stamen; carpels d. megaspores; microspores
- Which of the following is correct regarding female gametophyte development in Angiosperms? The female gametophyte develops in the anther The female gametophyte develops in an ovule within an ovary A female gametophyte develops from all four megaspores produced via meiosis All cells of the female gametophyte are haploidWhich of the following is a characteristic of both angiosperms and gymnosperms? production of seeds production of flowers lack vascular tissue production of conesWhich of the following is unique to angiosperms? Large vascular tissues (vessel elements) that support broad leaves Lignin that provide structural rigidity Stomata that enhance gas exchange Seeds that enable dormancy
- What is the genetic load in angiosperms and gymnosperms of the following structures: Microsporophyll Microsporangium Microsporocyte Microspora Microgametophyte Megasporophilic Megasporangium Megasporocyte Megaspore MegagametophyteWhich of the following adaptations possibly explain(s) why angiosperms are more diverse than gymnosperms on planet Earth: Group of answer choices Seeds Seeds AND Fruits and Flowers AND Pollen tube Fruits and Flowers Fruits and Flowers AND Pollen tube Pollen tubeWhich of the following is not a characteristic of ALL seed plants? Produce flowers Dominant sporophyte generation Highly reduced gametophyte Can inhabit harsher and drier environments than ferns
- The evolutionary relationships among the major groups of seed plants are uncertain. The cladogram below is one possible representation of these relationships. Which of the following can be inferred from this cladogram of the seed plants? eudicots monocots other angiosperms angiosperms water lities Amborella conifers gnetophytes gymnosperms cycads early seed plants girikgo /Which of the following is NOT a caharacteristic of all seed plants? 1. a sporic life cycle 2. cell walls containing cellulose 3. life cycle is dominant in the sporophyte phase 4. reproductive organs found in flowers 5.nearlly all are photo-autotrophicThe classification of the seed plants has varied. If a person groups all seed plants together in one large Division Spermatophyta, then they have two classes—the class with naked seeds and the class , plants with carpels. On the other hand, many people (and this book) use four divisions, not one. List the three divisions of “gymnosperms” and the one division of flowering plants.
