Double Fertilization in Plants

Critical Thinking: Can a seed carry out photosynthesis? _______ Why or why not? ________________________________________________ Where does a seed get its initial energy to grow? From __________________

In angiosperms (flower-bearing plants), the pollen grain has two sperm. Double fertilization is named such because both of these sperm are necessary for the fertilization of the plant. Each sperm have one half the total number of chromosomes required for the plant (n - haploid in number) A pollen tube forms from the pollen grain and extends down the style, into to the ovary and finally to the ovule, carrying the two sperm with it. Once the sperm enter the ovule, they each have different defined jobs. One of the sperm (n) will combine with the egg (n) and become the zygote (2n – diploid #) that will ultimately become the new plant. The other sperm (n) will combine with two cells called polar bodies (each n) now called the endosperm nucleus that becomes the endosperm which serves as food for the developing seedling.

Flower Dissection Lab

Purpose: Identify the parts of the flower & indicate which parts make up the male & female reproductive units

1. Common name of your flower: __________________________________________ 2. Scientific name of your flower: __________________________________________

Examine each of the following parts. Record how many you find in your own flower

Example Diagram Diagram & Label Your Flower Structures

Color male o and female o parts different colors.

Sketch and label the parts of the flower. (An example is provided for you.) Directions: Count and record how many of each structure your flower has. a. Sepals (Thick outer parts that protect the flower when it is closed) ___ b. Petals (Colored and often fragrant parts that attract pollinators) ___ c. Anthers (Football-shaped male organ at the end of the stamen, analogous to testicles in mammals) ___ d. Pollen Grains (Tiny yellow, precursor to sperm cells, made by the anther) ___ e. Stamen (male reproductive organ, comprised of the anther and filament) ___ f. Carpel (female reproductive organ: stigma, sticky nectar at the top, style leading to the ovaries with eggs at the base) ___ g. Eggs (tiny granules of female gametes or sex cells, housed in the ovaries) ___

Directions: Carefully separate and isolate each of the structures listed below. Mount each one below.

“Hay fever” is an allergic reaction to pollen floating in the air. Some plants that use the wind to spread their pollen are grass, trees and corn. Find or sketch a magnified image of pollen in the space provided

Analyze and Conclude:

1. Observing: Were the anthers in your flower located above or below the stigma? _________________

How could this affect what happens to the pollen produced by the anthers? Explain your answer. _________________________________________________________________________ _________________________________________________________________________

2. Applying Concepts: What structures did you identify on the anther? ___________________________

What is the function of these structures? __________________________________

3. Applying Concepts: What structures did you identify in the ovary? ________________

What is the function of these structures? _________________________________ 4. Drawing Conclusions:

When people eat fruit, what are they really eating? __________________________________________ When people are allergic to pollen, what are they really allergic to? ______________________________
