Big Idea 3-20

20) Tropism- the response or orientation of a plant or sometimes animal to an external stimulus. Tropism can be positive, when the organism moves towards the stimulus, or negative, when the organism moves away from the stimulus. The image above is of daisies. They are plants that turn towards where the sun usually is. This is called phototropism. 

Big Idea 2-11

11) Denaturation- the change in a protein's shape or the shape of another molecule. Some Molecules like proteins are very  sensitive and require a specific environment to function properly. If a protein's environment becomes too hot, acidic, or basic the protein will change shape and basically die. It loses its function. This is why homeostasis in people is so important. The image of fire represents how extreme heat can denature proteins or DNA.

3-8) Flock, Herd, Schooling- a flock is a group of birds that migrate and live together. A herd is group of animals usually mammals that live and migrate together. Schooling is when a group of fish swim in an organized manner in the same direction. The image above is of sulcata tortoises. A group of tortoises is called a "creep." 

Big Idea 2-29

29) Long Day Plant- a plant that blooms when the days are longer, usually in the summer. They require at least 12 hours of sunlight exposure and don't need to be left in the darkness for too long to bloom. Clovers are a type of long day plant that are important to many ecosystems because of the nutrients they provide. 

Big Idea 4-7

7) Detritivore- an organism that eats organic waste. The image is of a woodlouse. They are a type of Detritivore, which means they eat decomposing plants, animals, and poop. Other detritivores include earthworms, dung beetles, and millipedes. 

Big Idea 1-27

1-27) Lichens- are a combination of a fungus and an alga. The fungus is the body and the alga is the food producer. They often form on trees, rocks, and walls. The image above is of my tree at home. It has a bunch of lichen growing on its branches.

Big Idea 1-20

20) Fungi- eukaryotic organisms that live on dead or decaying things. Mushrooms, like the one in the picture, are a type of fungus that grow from the soil and release spores to reproduce. Fungi can also grow on trees and basically anywhere with decomposing material that is damp enough.
