This is a picture of a pine cone. Pine cones are an example of gymnosperm cones. Gymnosperm cones are a group of cones whose seeds aren't blocked by the ovule. They have no flowers or fruits. Pine cones close their scales to shield their seeds from colder weather, winds, and possible predators. They open up their scales to release their seeds when it is warmer and so it is easier for the seeds to germinate.

This is a picture of a banana. Bananas produce ethylene gas. Ethylene is a clear flammable gas acquired from natural gasses and petroleum. It also serves as a natural plant hormone used to combine or cut metal and ripen fruits. Since bananas produce ethylene gasses, they are capable of assisting certain fruits in riping or melting. Ethylene can cause fruits to change colors, smell, and taste.

This is a picture of two acorns. Acorns are an example of seed dispersal. Seed dispersal is the transfer of a seed from the original plant. Squirrels often bury acorns but forget where they place them, leaving the acorn to develop into a new plant.

This is a picture taken of several flamingos. These flamingos represent a population. A population is a group of the same species in a certain area. This group of flamingos was spotted in their exhibit at the Maryland Zoo. There is more than one animal in this exhibit, making it a population.

This is a picture taken of a turtle. Turtles are ectothermic. An ectotherm is an organism that relies on outer sources of body heat. Fish, reptiles, amphibians, and invertebrates are ectotherms. Turtles are cold-blooded, therefore, they aren't capable of warming themselves up in colder climates, causing them to migrate to warmer climates.

This is a picture of my cat. Cats are endothermic. An endotherm is an organism that can keep its body a favored temperature. They are warmed-blooded. Mammals and birds are endothermic. Cats don't have to rely on their environment in order to keep themselves warm. Their inner body temperature is something they can manage on their own.
