Kelly - Scavenger Hunt post #6

I will be in Houston all next week at NYLF. I can't wait to tell you how it went.

1. The Giant Flying Fox Bat (Pteropus vampyrus) and the Taveta Golden Weaver (Ploceus castaneiceps) are eukaryotes.  Eukaryotes are organisms with one or more cells that have organelles and a membrane bound nucleus containing DNA. All animals are eukaryotic. Bacteria, viruses and some blue-green algae are not eukaryotes; they are prokaryotes.

2. The sweet potato is an example of a modified root, one that has a function other than absorbing water and anchoring the plant. In the roots of plants like sweet potatoes, carrots and beets, the roots become enlarged. Starch and other carbohydrates are stored where there are extra parenchyma cells in the roots.

3. Long-day plants bloom when they have more than 12 hours of light. It is actually the amount of darkness that a plant has that determines whether a plant would form flowers. So long-day plants need a short night to bloom. The way a plant reacts to the length of light and dark time is called photoperiodism. The Lettuce in this picture is an example of a long-day plant.

4. This is a picture of an African Lion. The lion is a predator, meaning it feeds on its prey. Giraffe, buffalo, antelopes and zebra’s are some of the animal a lion will hunt. Because they are high on the food chain, lions have few predators, one is the hyena. Lions and hyena live in the same niche so they compete for resources. Lions will follow a hyena when they are hunting and feed on killed animals stolen from the hyena. They will attack each other but they don’t eat the meat from the dead prey. Occasionally a Nile crocodile will be a predator that can get a lion.

5. This picture is of a plant in EPCOT that is being grown without soil. Nutrients are sprayed on to the roots. The apical meristem is found at the tips of the roots and stems. This is the area where the cells can divide, producing new cells.
