- 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.In the mature angiosperm seed, the nutritive tissue is triploid. This tissue is formed from; Two polar nucleii fusing with a sperm cell The synergids fusing with a sperm cell The sperm fusing with the egg cell The embryoWhich of the following is a characteristic of both angiosperms and gymnosperms? production of seeds production of flowers lack vascular tissue production of cones
- Which statement below is correct regarding the formation of the endosperm in angiosperms? O the endosperm is formed from the female gametophyte and is haploid O a single sperm nucleus fertilizes the egg nucleus to become the diploid zygote O a sperm nucleus forms both the zygote and the endosperm through double fertilization O a second sperm nucleus fuses with the two polar nuclei of the egg sac МacВook Pro G Search or type URL @ 2# $ & * 2 3 4 6 8 W E R YMost of the approximately 900 species of gymnosperms are conebearing plants. On the surfaces of their cone scales are ovules, which later become seeds. These ovules are said to be naked because they are not completely enclosed by diploid tissue (as the ovules of angiosperms are). This characteristic gives the gymnosperms their name; gymnos is a Greek word meaning naked, and sperma means seed. Botanists now divide the gymnosperms into four groups: conifers, cycads, ginkgos, and gnetophytes.using the illustrations above arrange the following statements to explain the process of pollen formation in angiosperms "using the illustrations above, arrange the following statements to explain the process of pollen formation in angiosperms"
- Which 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 dormancyWhich of the following traits are unique to Angiosperms? Heterosporous Pollen tube growth Dominant sporophyte Triploid tissue present in the seedsA fertilized egg becomes an ______ and the joining of polar nuclei and spem becomes the triploid(3n) endosperm. The ovule wall becomes the seed coat. A seed contains a sporophyte embryo, stored food, and a seed coat. In angiosperms, seeds are enclosed by ________.
- Which of the follow correctly describe the function of a cone? Question 32 options: Carries the microgametophyte and sperm cells during sexual reproduction in angiosperms. Contains the plant embryo and a tissue such as endosperm to provide nutrition for early plant growth. The reproductive structure of the gymnosperms. Grows from the ovary of a flowering plants and surrounds the seed. Provides protection and/or attracts animals to aid in seed dispersal. The reproductive structure of the angiosperms.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 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 tube
