What Does a Scavenger Hunt Post Look Like?

SUGGESTIONS FOR YOUR SUMMER “BIOLOGY SCAVENGER HUNT” ASSIGNMENT

You will need to publish about 50 photos. Please do NOT make a new blog entry every time you want to publish photos. Please publish all your photos in ONE or TWO blog entries. That means make a blog entry for your Summer Scavenger Hunt assignment (titling it something like “Eb’s Biology Scavenger Hunt”) and keep adding your photos to that same entry. So each time you come back to the blog, go and EDIT your original blog post.

I would suggest you number your photos or captions, so it helps you keep track of your progress.

What are we looking for?
Photos of biology concepts and brief explanations of what the concept means and how your photo illustrates the idea. These do not have to be long explanations. They can just be a few lines that clearly state what Biology Scavenger Hunt concept your photo is depicting and how it clearly satisfies that category.  Scroll down to the next blog for a few examples!

AP Biology Scavenger Hunt Examples

(1) Basidiomycetes, or club fungi, have fruiting bodies we commonly call mushrooms.  Basidiomycetes fungi are important decomposers of wood and other plant materials.  Of all the fungi, basidiomycetes is best at decomposing the complex polymer lignin, and abundant component of wood. After a mushroom, a basidiocarp, forms, its cap supports an protects a large number of basidia or gills.  Each basidia goes through meiosis and produces basidiospores which will give rise to the next generation.

(2) Decomposition is a primary function carried out by many fungi.  Thus fungi are considered decomposers.  This means fungi are organisms that absorbs nutrients from nonliving organic material such as the bodies of dead animals, the remains of dead plants, and the waste products of living organisms and converts these organic compounds back into to inorganic forms.  These inorganic molecules are now available to producers so the cycling of matter may continue.  Without decomposition the biogeochemical cycles would cease to function and key elements would become “locked” up.


Flowering plants (angiosperms) reproduce sexually.  The female portion of the flower is known as the pistil which consists of a stigma, style, and ovary.  The plant ovary contains the female gametes known as eggs that are fertilized by the male gamete known as pollen.  Each fertilized egg becomes a seed.  Each seed contains the embryo and its food source known as the endosperm.  The (3) plant ovary surrounding the seeds often develops into a fruit.  In the picture below, each pea pod is a fruit that developed from the flower’s ovary.  In each pod is typically 4-8 peas, or seeds, that are each individual embryos that can each grow into a new plant.


 

The bee in the photo below is serving as a (4) pollinator.  The bee will move from flower to flower feeding on the nectar the plant has to offer.  As the bee feeds on the nectar it will rub up against the pollen produced by the flower’s stamen.  Some of the pollen will adhere to the bees body.  When the bee moves to a new flower, some of the pollen attached to its body will stick to the sticky stigma of the female’s pistil on the new flower.  This is known as cross pollination, where the pollen of one flower is used to fertilize the egg of a different flower.  Bees are a very important pollinator and there is great concern about their decreasing numbers (mainly due to pesticides)  and what impact this might have on plants, particularly food crops.
