Learning Goal: I’m working on a biology multi-part question and need an explanation and answer to help me learn.In this assignment, you will examine the intricate structures that compose a flower. Many angiosperms have, in a single flower, both the male and the female sex organs surrounded by petals. The egg (female haploid cell) and the pollen (containing one or more haploid sperm nuclei) are contained in the same flower. Angiosperms may self-fertilize if pollen from a flower is transferred to egg cells in the same flower, or they may cross-fertilize. Carried on the wind or by other means, pollen grains from other flowers may land on the sexual organs of a flower and fertilize it. Once you have completed this lesson you should be able to:Identify the sexual organs of angiosperms, including: carpel, stigma, style, egg, petal, stamen, anther, pollen, filament, and sepal.
Describe the functions of the major sexual organs of a flower.
Explain how an egg combines with pollen inside the flower to produce a fertilized seed.
Dissect a flower and produce correctly labelled diagrams from this dissection.
InstructionsYour task is to complete the flower dissection and create FIVE labelled biological diagrams. MATERIALSYou will need the following items to complete this activity:Simple flowers (e.g., hibiscus, tulip, daffodil)
Scalpel or razor blades
NOTEFor this assignment, ensure you are using a simple flower, following the examples provided, and not a composite flower (e.g., dandelion, chrysanthemum, dahlia, goldenrod).PROCEDUREObtain a large flower and examine it as a whole. Sketch and name your flower. Call this Diagram 1.
Examine the texture and colour of the sepals and petals using a magnifying glass. If your flower is coloured, pinch a small piece of a petal between your fingers and examine the colourful pigment released.
Carefully remove or pull back the petals of the flower to expose the stamens. How many stamens do you see in your flower? Draw and label a diagram of your stamen. Call this Diagram 2.
Examine the anther on your stamen using a magnifying glass and touch the tip of your finger to the anther. Did any pollen rub off on your finger?
To see the carpel clearly, gently separate the flower from the green sepals and petals. The stamens will usually stay with the flower petals and the carpel usually remains attached to the base. Sketch and label the carpel. Call this Diagram 3.
Touch the stigma on the carpel. What do you notice? Examine the stigma with your magnifying lens. Sketch what you observe. Call this Diagram 4.
At the bottom of the carpel is the ovary. Cut open the carpel longitudinally in order to observe the ovary. Use a magnifying glass to examine the exposed ovary. Sketch and label what you observe. Call this Diagram 5.
SAFETYThe following precautions should be noted prior to starting this activity:Do not touch the pollen if you have an allergy to it.
Exercise caution with the scalpel. It is very sharp.
Do not eat any part of the flower. Some flowers are toxic and may have negative side effects.
ASSESSMENT DETAILSYour submission should include the following:DIAGRAM 1: THE FLOWER
DIAGRAM 2: THE STAMEN
DIAGRAM 3: THE CARPEL
DIAGRAM 4: THE STIGMA
DIAGRAM 5: THE OVARY
