Flower ovary: The ovule-bearing lower part of a pistil that ripens into a fruit, or flower.
I cut open into this flower to show the actual ovary and ovule of the flower.
Hydrophilic: Had a tendency to be mixed with, or dissolved in water. It is water loving, such as phosphate heads that make up the phospholipid bilayer of a cell membrane.
I did an experiment mixing sugar into a glass of water, dissolving it, proving it was hydrophilic.
Mullerian Mimicry: Mimicry is the similarity of one species to another which protects one or both.
As in this picture, I tried to show how these two knives are both similar and different. One is a butter know and one can be used for vegetables. Both for different, but share a common goal like many insects and animals.
Genetic variation within a population: The alleles within a population change. Gene variation is also an important factor in natural selection. In a snowy area, there could be a white rabbit and a brown rabbit. Factors show that the brown rabbit will be easily spotted and killed by the predator before the white rabbit. The white rabbit living in the snowing terrain is more camouflaged then the brown rabbit.
These flowers are bother the same species, but one in orange then the other is yellow.
Prokaryote: a unicellular organism having cells lacking membrane-bound nuclei.
Cleaners lack membrane-bound nuclei, classifying as prokaryotes.

(The prop I used before, the penguin, could not be found for this photo shoot)
K-strategist- Species that usually concentrate their reproductive investment in a small number of offspring.
Like my dog Marley, if he were able to have pups, they would be in smaller litters than other animals. (Example: dogs may have 2 to 5 pups, while frogs can lay several eggs)
Fermentation: The process of this kind involved in the making of beer, wine, and liquor, in which sugars are converted to ethyl alcohol.
This is a picture of different wines and beers that all went through fermentation.
Batesian Mimicry: An edible animal is protected by its resemblance to a noxious one that is avoided by predators.
Knives is just an example of how some people protect themselves from a predator, as animals can use they're claws and other objects.
Cellular Respiration: also known as 'oxidative metabolism', is one of the key ways a cell gains useful energy.
This tree uses various resources to gain energy.
Cuticle layer of a plant: The waxy covering of a leaf.
They are also on fruits was well, but described as the thickness of the fruit.

Homoeostasis: The ability of an organism to maintain an internal equilibrium. It means that there has to be a state of balance among all the body systems to survive.
Horses use homoeostasis by getting exercise, eating, digesting food, getting rid of waste, and sleeping, all to create a well balanced life to help them survive.
Niche: Place or position.
I noticed that clovers grow in patches or groups in shady areas. This area is the clover's niche.
Anther & filament of stamen: An anther is the part of the stamen that contains the pollen. The filament is the male reproductive part of a plant. The stamen is the male fertilizing organ of a flower.
As you see in the picture above, it shows the anther and filament of the stamen and pollen as well.
Gymnosperm cone (male or female)-  a gymnosperm is a vascular plant having seeds that are not enclosed in an ovary.
This is and example of a female cone. Female cones are bigger than male cones.
Ectotherm:  An animal that is dependent on external sources of body heat.
My cat Katelyn is an example of an ectotherm..

Hydrophobic: Repelling water. (like fatty acid tails) meaning they hate water, and they are not polar.
This is a picture of my cat Katelyn. Like the fatty acid tails which are hydrophobic, she repels water as well.
Eukaryote: An organism consisting of a cell or cells in which the genetic material is DNA in the form of chromosomes contained within a distinct nucleus.
I'm an example of a eukaryote.
Analogous structures: a body part in two or more species that performs a similar function but has a different structure.
Such as my arm, and my dog's arm. They both perform similar tasks.

Amniotic Egg: An egg that contains a thin membrane that forms a closed sac with an embryo or fetus of a reptile, bird, or mammal. The sac also contain amniotic fluid.
This picture is of a bird egg that I found laying on my porch. Unfortunately, the egg was abandon by the mother and was unable to hatch. This is also another example of survival of the fittest.
Lichen: A simple plant consisting of a fungus.
This shows a tree with lichen growing on it.

                                            This is my hand. It shows epithelial tissue,
                                            a tissue that lines the outside of your body and
                                            the lining of your organs.

                                                   This clematis vine shows plant adaptations.
                                                   The plant has adapted to climb above the
                                                    ground to recieve more sun. This in turn
                                                     causes it to grow.

                                            This bannana is showing signs of ripening.
                                            Ripening is caused by the fruit producing
                                             ethylene. It can cause a stop in cell division
                                              and growth.

 This vinca, like all plants and plant-like      
protists, is an autotrophs. Autotrophs are    
any organisms that produce their own food.


                                        This common commercial succulent, Hens & Chickens,
                                         is a CAM plant. This means the plant only opens its stomata
                                         at night for photorespiration.



                                                       Beer is a good example of fermentation.    
                                                       Fermentation is a metabolic process that    
                                                       cells can use to obtain energy from            
                                                       organic molecules. It does not use oxygen.


                                    This shows mutualism of clearwing moths and wild bergamot.
                                    The moth transfers pollen from the plant to other plants for
                                    reproduction while the moth gains nectar from the plant.
                                    Both organisms are helped by each other.

This is the leg bone of a muskrat. It is a homologous structure. It shows a shared ancestry with many
organisms.

Mallard ducks, like many organisms, show bilateral symmetry. Bilateral symmetry means the animals appendages are on equal and opposite sides of the body axis.

This day lily shows the anther and filaments of a complete flower. The anther and filament are the male sperm-producing parts of the plant.                       

This tree stump shows the cambium layer of a vascular plant. The cambium contains the xylem and phloem of the plant. It makes up the bulk of the plant.


This is a common tree decay fungus. Fungi are set in adifferent kingdom than plants because of their unique abilities. Most mushrooms are decomposers, reducing dead organic material into
microscopic matter.
