When a pollen tube grows through the style and enters into the ovules, it finally discharges two male gametes in one of the synergids. Syngamy and triple fusion are two fusion events occur in angiosperms. Thus, angiosperms exhibit double fertilization. The products of these fusions are the diploid zygote and triploid primary endosperm nucleus. Zygote develops into embryo and primary endosperm cell forms the endosperm tissue. The developing embryo passes through different stages before maturation.<\/div><\/div><span class=\"dqc-qstem\">With reference to reproduction in flowering plants, which one of the following is incorrect?

Since the meiocyte of maize contains 20 chromosomes (2n = 20), the resulting gametes will contain 10 chromosomes (n = 10).<\/p><\/div>\n                    <\/div>\n                    \n                                        <div class=\"dqc-exp-section dqc-exp-wrong\">\n                        <div class=\"dqc-exp-title\">\u2753 Why Other Options Are Incorrect<\/div>\n                        <div class=\"dqc-exp-body\"><ul class=\"dqc-exp-list\"><li>Option B) 20 \u2192 Represents diploid chromosome number, not gametic number.<\/li><li>Option C) 24 \u2192 Not related to chromosome reduction from 20.<\/li><li>Option D) 40 \u2192 Chromosome number cannot double during gamete formation.<\/li><\/ul><\/div>\n                    <\/div>\n                    \n                                        <div class=\"dqc-exp-section dqc-exp-strategy\">\n                        <div class=\"dqc-exp-title\">\ud83c\udfaf Strategy<\/div>\n                        <div class=\"dqc-exp-body\"><p class=\"dqc-exp-para\">Used: Dimensional\/Unit Analysis<\/p><ul class=\"dqc-exp-steps\"><li>Option A \u2192 Half of diploid number.<\/li><li>Option B \u2192 Original diploid count.<\/li><li>Option C \u2192 Arbitrary value.<\/li><li>Option D \u2192 Opposite of meiosis outcome.<\/li><\/ul><ul class=\"dqc-exp-list\"><li>Final Answer \u2192 Meiosis halves chromosome number.<\/li><\/ul><\/div>\n                    <\/div>\n                    \n                                        <div class=\"dqc-exp-section dqc-exp-memory\">\n                        <div class=\"dqc-exp-title\">\ud83e\udde0 Memory Trick<\/div>\n                        <div class=\"dqc-exp-body\"><ul class=\"dqc-exp-steps\"><li><\/li><\/ul><\/div>\n                    <\/div>\n                    \n                    \n                                        <div class=\"dqc-ncert-tag\">\ud83d\udcda \u2192 Section\/Theme: Microsporogenesis and Meiosis<\/div>\n                                    <\/div>\n                            <\/div>\n                        <div class=\"dqc-rev-q\" id=\"dqc-rev-q-57\">\n                <p class=\"dqc-qtext\"><span class=\"dqc-qnum\">3<\/span> Which layer of microsporangium nourishes the developing pollen grains?

When a pollen tube grows through the style and enters into the ovules, it finally discharges two male gametes in one of the synergids. Syngamy and triple fusion are two fusion events occur in angiosperms. Thus, angiosperms exhibit double fertilization. The products of these fusions are the diploid zygote and triploid primary endosperm nucleus. Zygote develops into embryo and primary endosperm cell forms the endosperm tissue. The developing embryo passes through different stages before maturation.<\/div><\/div><span class=\"dqc-qstem\">With reference to reproduction in flowering plants, which one of the following is incorrect?
