This fern is an example of a plant that has frond leaves. A frond is a large, finely divided leaves. Palm trees are another example of a plant with frond leaves.
 

These cows are an example of K-strategist. That means that they have few and often large offspring. Cows normally only have one offspring at a time but it has been known for them to have twins. A baby cow is called a calf.  
 

My kitty is an example of R-strategist, which means she'll have a large number of small offspring at a time. A cat usually has anywhere between 2 to 9 kittens. A group of offspring for a cat is called a litter.

An example of the cuticle layer of a plant is leaves. The covering of leaves are produced by epidermal cells in the leaves.
The bee on the flower is an example of a pollinator. When the bee lands on the flower, it pollinates it. A pollinator is a living pollination vector. Butterflies and hummingbirds are other examples.

1. Marigold's serve as an example of a Flower Ovary. Marigold's contain both, female and male parts. The female part is the ovary.

1) These flowers are an example of an autotroph. All plants are considered autotroprhs because they produce their own food.


2) Oil and water is an example of a hydrophobic mixture. The oil fails to mix with the water, and therefore it is hydrophobic.
3) Salt is an example of a hydrophilic substance. It absorbs and dissolves into water.

4) These chickens are an example of heterotrophs because the rely on other sources to provide them with food.  


5) Josh is an example of bilateral symmetry. Bilateral means having two sides. And the two sides would be, in this case, considered symmetrical. 


6) One endosperm that we eat is popcorn. Endosperm is a tissue that you find inside seeds of flowering plants.


7) Chicken eggs are an example of amniotic eggs. Amniotic eggs are produced by reptiles and birds.    


8) My cat, Snickers, is an example of an endotherm. Although the environment around her may change, her body temperature stays the same. Endotherms include most mammals and birds.


9) Worms are examples of detritivores, also known as decomposers. They obtain energy from dead & organic matter.  


10) C4 plants, such as corn, are only able to fix carbon in certain conditions.


11) Yogurt is made from fermented milk,  which produces the lactic acid to thicken to milk/yogurt. 


12) Lipids are fats from oils used for storing energy. Foods that contain lipids are mainly meats and dairy products.


13) Gibberellins are several plants hormones used to promote stem elongation. Gibberellins are used on most grapes in the US.



14) Coniferous plants are gymnosperms, meaning their seeds are out in the open. These pine needles come from a conifer. 


15) Predation helps one species at anothers expense. Predators are organisms that kill their prey. An example would be Snicker's and this (toy) mouse.


16) Homeostasis is the state of an internal environment of an organism. It has to be maintained by all organisms at all times.


17) This is the stamen of a flower, which is the male reproductive organ of a flower.  It produces pollen in the anther, and the slennder stalks below are the filament.


18) This is a picture of my grandpa's dog. He is an example of a K Strategist. K Strategists are species that reproduce in small amounts in hopes that all will survive. They also live longer and reproduce slowly. Another example would be humans.


19) R Strategists are the opposite of K Strategists. They have many offspring, making it impossible for all to survive.


20) Lettuce is an example of a long-day plant because it has to be exposed to longer periods of light, such as in the summer.


21) The body of an ant is segmented, meaning it is divided into three parts: the head, thorax and abdomen.


22) Mutualism is beneficial to both organisms, such as the relationship between the bee and flower.


23) Glycogen is a polysaccharide used for energy storage. In humans, glycogen in its highest concentration is found in the liver.


24) Rhizomes are underground, horizontal plants stems that produce the roots and shoots of a new plant. Examples of rhizomes could be potato tubers.


25) Rice is an example of a C3 plant. In a C3 plant, the carbon fixation products consist of three carbon atoms per molecule.


26) Ethylene gas Iis given off by ripe fruit. It is responsible for many plant processes. It can be given off by ripe tomatoes, such as these from my dad's garden.


27) Genetically modified organisms are organisms that have been somewhat altered or changed. An example is corn. Corn was modified tovmake its own pesticide.


28) Crustaceans, such as shrimp, have exoskeletons. The exoskeleton has a blue-green color. They contain carotenoids (the pigment) and when tthey're covered with protein chains. 


29) Most animals are eukaryotic, which means their cells contain one distinct nucleus. These are some of the dogs that I watched earlier this summer. 


30) Pollinators, such as bees and hummingbirds, move pollen from the anther to the stigmas in flowers. These are the honey bees my dad raises.


31) Phloem is a tissue in vascular plants that helps carry nutrients. Phloem is located in tree bark.


32) Between the bark and the wood Iis the cambium layer, which is responsible for creatingannual rings, which increases diameter. 


33) Mutualism is beneficial to both organisms, such as the relationship between this butterfly and flower.


34) Laundry detergent has enzymes Iin it, like many other things. It has special enzymes to break down the build-up of dirt and remove stains.


35) A prokaryotic cell is just the opposite of eukaryotic cell. It has no nucleus. Prokaryotes are usually smaller like bacteria. Household cleaners usually help destroy bacteria.


36) An example of a gymnosperm cone would be a pine cone. A pine tree Iis a gymnosperm because their seeds are stored in cones, not fruits.


37) Birds have adapted Iin many ways to help them survive. The wing is a perfect example. Thanks to evolution, they were able to create the perfect wings. Plus, most birds have beak adapted to what they eat.


38) In asexual reproduction, one Iindividual producesoffspring that are genetically identical to itself through mitosis. Sea stars, sponges, and some fish can reproduce this way.


39) Analogous structures refers to the same structures in different animals that serve the same purpose. Several animals depends on their wings, such as this moth. 


40) Epithelial tissue covers the whole surface of the body. Its made of closely packed cells and has one or more layers. Our skin is one example. 


41) One example of a unicellular organism is yeast. This means that yeast only has one cell.


42) Lichen Iis a type of fungus that can grow anywhere on land. It's often found on trees, and in many different colors.

43) Cellular respiration is a metabolic process that occers in plants and animals. In this process, the cells convert energy from nutrients to ATP. It is vital to all plants, like these plants and trees in the Bahamas. 

44) Cartilage is a type of dense connective tissue. It is found in many joints plus your nose and ears. This is a photo of ny sister Anna's ear.


45) This is a photo that I took up at Tygart lake. Many fish inhabit this lake and call it home.The area is considered a niche for these fish.


46) This is a photo of a snapping turtle in my basement. Turtles are ectotherms, which means they are cold blooded. All reptiles are ectotherms.


47) Xylem is mainly involved with transporting water and nutrients from the roots to the shoots and leaves and supporting the structure. 


48) The ovart of a flower is the enlarged portion of the pistil, where ovules are produced. They eventually develop into seeds.


49) Pollen is the fertilizing element of flowering plants. It can be found on flowers, like these on my front porch.


50) Bysidiomycetes, such as mushrooms, include any members of a large group of fungi. They bear sexually produced spores.
