This flower contains pollen. Pollen is a powdery, yellow substance that are used by plants to help fertilize other plants and create seeds. Pollen is transported to other plants by water, wind, and pollinators like bees (pictured above).

Modified roots are roots that adapt to the environment to ensure survival. A potato is an example of a modified root. A potato is a storage root and helps the plant survive by storing water and other nutrients to prepare for unfavorable conditions.

This is a picture of an earthworm. An earthworm is an example of a detritivore. A detritivore is an organism that eats dead organisms and breaks them down. Worms break down dead organisms and return the nutrients back into the ecosystem.

Homeostasis is the act of maintaining equilibrium in the body. After a long walk, my dog is panting. His panting is regulating his body temperature and bring it down. The regulation of body temperature is an example of homeostasis.

A population is a group of the same species that inhabit one specific region. These three cats make up the cat population of the Millner household.

Territorial behavior is how an animal protects it's land and resources. In this picture, the hummingbird is fighting off other hummingbirds from the feeder. The hummingbird is protecting its food, therefore exhibiting territorial behavior.

Heterotroohy is the act of eating another something in order to gain its energy. In this picture, my dad is eating a sandwich. By eating the sandwich, he is gaining energy from the tomato and lettuce.

Even though my cat may not look like it, she is a predator. Predation is the act of hunting or preying on something. In this picture, my cat is pouncing and attacking the string ball.

Chachi's canines are an example of an animal adaptation. Dogs are carnivores which means that they need something to rip and tear meat. Overtime, they developed canines in order to eat their food easier. Chachi's sharp teeth make it easier for him to hunt in his environment.

My dog, Chachi, is an Endotherm. Endotherms, like birds and mammals, are capable of producing their own body heat. Chachi doesn't need an outside source to regulate his body temperature.

This is a picture of my beta fish. My fish requires a specific water temperature or else it will die which makes it an ectotherm. Ectotherm's are organisms that can't produce their own body heat and require heat from external sources.

This is a picture of thorns on a blackberry bush which is a plant adaptation. A plant adaptation is something the plant changes whether it's the structure or lifestyle in order to survive in its environment. This blackberry bush adapted throns to keep other animals from eating its berries.

This is a picture of a flowering plant. Every flowering plant has a male reproductive organ in the form of the stamen. The stamen is composed of the anther and the filament. The filament is the long stalk in the very middle of the flower, and the anther is at the top of the filament. The anther collects pollen and helps with flower fertilization.

This flower has radial symmetry. Radial symmetry is when an organism is symmetrical with respect to it's center. If you started in the center of the flower, no matter how you split it, the flower would be symmetrical. 

A pinecone is an example of a gymnosperm cone. Gymnosperms are non-flowering plants that produce "naked" seeds. Gymnosperms like pine trees protect their seeds using cones such as this pinecone.

This picture of a dragonfly exhibits bilateral symmetry. Bilateral symmetry is the organism is equally balanced on both sides. If you cut the dragonfly in half, then the dragonfly is the same on both sides.

This is a picture of a vine on a tree branch. This represents parasitism, because the vine is benefitting off of the tree while the tree is either getting harmed or dying. The vine is taking some of the tree's nutrients, which causes the tree to not be as healthy as it should be. 

This is a picture of pine needles. A pine tree is an example of a gymnosperm and it's needles are the leaves. Gymnosperms are non-flowering plants that produce seeds that aren't within fruit. A pine tree is a gymnosperm that produces it's seeds enclosed in pinecones.

This is a picture of a bee pollinating a flower. A pollinator is an organism that moves pollen from one plant to the other, which helps fertilize plants and create seeds. This bee is collecting pollen and moving it to the other plants that it visits.

This is a picture of a spider. The spider has a segmented  body with a head, thorax, and abdomen. A segmented body is an organism's body that you can divide into different regions. All arthropods, like spiders, have segmented bodies.

This is a picture of the cuticle layer of the leaf. The cuticle layer is the shiny, waxy part of the leaf which protects the leaf from the heat and locks in moisture. These leaves have a waxy outer layer which helps keep the water from evaporating.

This is a picture of a modified leaf of an aloe vera plant. Plants modify their leaves in order to adapt to their environment by protecting themselves from predators or attracting more insects. This aloe vera plant has thorny leaves in order to protect itself from predators eating their leaves.

This is a picture of a blackberry bush with thorns on the stem.  Plants modify their stems in order to protect themselves from predators. This blackberry bush likely developed thorns in order to protect its berries from deer and other wildlife.

This is a picture of grass, which is an autotroph. An autotroph is an organism that takes light energy from the sun and converts it into chemical energy through reactions like photosynthesis. Plants, algae, and bacteria are all autotrophs. Grass takes in the sun's energy and converts it into sugar using photosynthesis for other organisms to eat.

This is a picture of my brown eyes and my dad's blue eyes. Our eyes represent dominant and recessive phenotypes. Brown eyes are a dominant gene which means they will always be expressed. Blue eyes are recessive which means that they will only show up when both parents have the gene. My dad's parents both carried the blue eye gene and passed it down to him. My mom's brown eyed gene masked my dad's blue eyed gene when passing their genes down to me and my sisters.
