*An amniotic egg is a shelled egg in which an embryo develops within a fluid filled amniotic sack and is nourished by a yolk

A chicken's egg (as shown in the photo below) is an example of an amniotic egg because it is a hard-shelled egg (unlike a fish or turtle egg) containing an embryo, which is held by a yolk.






*An angiosperm is a flowering plant, which forms seeds inside a protective chamber called an ovary.

A cannon flower is a flowering plant that forms seeds within an ovary, thus making it an example of an angiosperm. The ovary of the cannon flower is located deep within the flower, just above the stem, beneith the pedals and the piston.







*An arthropod is a segmented exdysozoan with a hard exosleleton and jointed appendages

Pictured and labled here is the shell of a cicada, which would be an example of an arthropod because it has a segmented ecdysozoan and appendages joined to its hard exoskeleton.





*An autotroph is an organism that obtains organic food molecules without eating other organisms or substances derived from other organisms.

Autotrophs use energy from the sun or from oxidation to make organic molecules from inorganic ones.

A rose (as pictured to the left) uses photosynthesis, converting energy from the sun into organic molecules, thus making a rose an autotroph. The rose above, although we can not see the process, is using photosynthesis to create nourishment for itself.


*A bryophyte is a nonvascular plant that lives on the land but lacks some of the terrestrial adaptions of vascular plants, such as moss.

In this photo (left), moss is using the nutrients in this tree's wood tissue in order to survive because, as a bryophyte, it lacks some terrestrial adaptions.




*A hermaphrodite is an individual that functions as both male and female in sexual reproduction bt producing both sperm and egg.

Many flowers, such as the rosa sharron (pictured to the right), have both female parts, ovaries, and male parts, stamen, thus making them examples of hermaphrodites.


*A parasite is an organism that feeds on the cell contents, tissues, or body fluids of another species (the host) while in or on the organism. Parasites harm but usually don not kill their hosts.

This photo to the left, is of termite (an example of a parasite) damage in the trunk of a tree. Although the termites, before being removed, caused great damage, the tree is still alive. This shows the type of damage that parasites can do to their hosts.





*Mutualism is a symbiotic relationship in which both participants benefit.



In this photo to the left, we see a bee pollinating a flower. With this, the bee collects pollen for itself but also pollinates the flower, helping it to reproduce.




*A female pinecone is typically larger and more durable than that of the male. After pollen is transferred from the male pinecone, the female, being pollenated, begins forming seeds within itself.

Once pollinated, the female pinecone forms seeds within itself. In time, the cone will fall from the tree, allowing its seeds to fall, in order to reproduce the tree. The pinecone in this photo to the left has already fallen and let go of it's seeds.


*Basidiomycete is a member of the fungal phylum basidiomycota, commonly called club fungus due to the club like shape.
Wild mushrooms (as shown in the picture to the right) are very common types of this fungi and can be found in any yard or woods.
