Chapter 38, Problem 5TYU
Summary Introduction
Introduction: In fertilization fusion of gametes occurs after the two sperm reach the female gametophyte. One sperm fertilizes the egg and form zygote. The second sperm combines with the two polar nuclei and form a triploid (3n) nucleus in the center of central cell of the female gametophyte. This cell will form endosperm. The union of two sperm cells with different nuclei of the female gametophyte is called double fertilization.

- Male and female flowers are present on different plants (dioecious) to ensure xenogamy, in: (a) papaya (b) bottle gourd (c) maize (d) all of these.arrow_forwardMost 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.arrow_forwardWhich 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 Yarrow_forward
- Why is fertilization in flowering plants called double fertilization? two cells in the ovule are fertilized, the egg and the endosperm mother cell it takes the efforts of two flowers (male and female) to produce seeds two ovules must be fertilized to form a single seed one pollen grain fertilizes two ovules it takes two pollen grains to fertilize a single ovulearrow_forwardAnswer the following question: What is meant by “double fertilization”?
