Consider a cherry pit, which is a seed with a cherry embryo inside it. Trace the paternal ancestry of that embryo. Explain how the sperm that fathered the embryo came to unite with the egg, and the process by which that sperm originated.

Summary Introduction

To explain: The paternal ancestry of the cherry embryo that is, how the sperm that fathered the embryo originated and how it united with the egg.

Introduction: Double fertilization is the process of formation of a zygote and the endosperm in flowering plants. It occurs when a pollen tube releases two sperm cells in the ovule. One sperm cell fuses with egg cell to form embryo and other sperm cell fuses with two polar bodies to form endosperm.

Explanation of Solution

A cherry pit is a seed consisting of an embryo. This embryo is the result of fertilization of an egg cell (n) in the ovule of a cherry blossom with the sperm cell. The pollen sacs in anther consist of diploid cells that form microspores by meiosis. These microspores develop to form pollen grains. When the pollen grains germinate on flower’s stigma and the pollen tube grow to the ovary, two non-motile sperm cells form in the pollen tube...
