Analogous Structures

Duck

Mosquito

     In the top picture, a duck is shown. Whereas, the bottom  picture shows a mosquito. The wings of the duck and mosquito are examples of analogous structures. Analogous structures are those structures that strike similarity in appearance, function, or arrangement. However, those pertaining animals have evolved independent of the other and have contrasting ancestors. The duck and mosquito both have wings which are structurally alike and the same goes for their purpose: flight. That being said, the duck and mosquito are different species and do not retain a common ancestor.

Stigma and Style of Carpel

     This is a picture of a white flower. It contains an example of the stigma and style of a carpel. A carpel is a long figure that serves as the reproductive system  in the center of a flower. In the carpel, there is a stigma which is a sticky tip. The stigma is where pollen is released from a pollinator for fertilization. A style of a carpel is the narrow stalk in the center connecting the flower ovary to the stigma, encompassing the major length of the carpel. It serves as the pathway for fertilization as the pollen tubes dwindle down sperm cells to the egg in the ovary. In this case, the white stalk in the middle fo the flower is the style  and the dark tip of the carpel is the stigma.

Cambium

      This is a portion of a tree that has been partially sawed off. This portion of the tree contains an example of cambium. Cambium is a collage of meristem cells that surround the stem of a plant and through this tissue phloem, xylem, or cork generate by dividing. This division can account for additional thickening in woody plants/ trees. The cambium on this portion of the tree is distinctly shown as the brown outline or border between the secondary thickening and the major wood.

Cuticle Layer of Plant

    This is an ordinary plant and its corresponding leaves. The plant's leaf is an example of a cuticle layer of a plant. A cuticle layer of the plant is the outermost covering that preserves the plant and guards it. This layer is usually made up of lipid and wax. On this leaf, there is a waxy thin layer that serves as protection for the plant.

Seed Dispersal

     This delicate plant is called a dandelion. This dandelion is an example of seed dispersal. Seed dispersal is any type of forced departure of a seed from its parent flower, whether it be an animal, water, or wind etc. The dandelion has seeds that were blown away by the wind and some by the aid of my hand movement, thus, showing seed dispersal.

Endotherm

     This feline creature is better known as a cat. This cat is an example of an endotherm. An endotherm is an animal that possesses the aptitude and necessity to generate internal heat with no dependence on external environmental factors. Endotherms are also regarded as " warm-blooded animals." This cat creates internal body heat to survive and does not rely on the environment outside to carry out this action. 

Ethylene

     These are a bunch of delectable and fairly sweet bananas. This bunch is an example of a plant that contains ethylene. Ethylene is a plant hormone that advocates several actions such as development, senescence and deterioration of dormancy, fruit ripening, and epinasty.The bananas showcased show the sign of ethylene as the color of the fruit transitions from green to yellow and ripens the fruit, making it sweeter. 

Auxin Producing Area of A Plant

     Behold, four different stages of flower blossoming taking place in this purple rose. This flowering plant exhibits many auxin producing areas of a plant. Auxin producing areas of a plant are those portions in a plant that simply form the plant hormone, auxin. Auxin is credited with the stimulation of cell elongation in certain areas of a plant. These areas include the stem, bud, and even root tips. For this exhibit, the auxin producing areas seen are in the bud area (green wrap encasing premature roses), where flowers are growing out from, and from the stem tips, causing elongation. In this picture, an underground view is not provided, so the auxin area in the roots is not displayed.

Animal That Has A Segmented Body

     In my hand, there is a tiny ant crawling. This diminutive ant is an example of an animal that has a segmented body. An animal that has a segmented body is one whose body is divided into a series of similar planes or portions. The ant showcased here has three main body segments including its head(beginning), thorax (middle), and abdomen (larger end.)

Modified Stem of A Plant

     This is a grapevine that has latched on to a wooden fence. A grapevine is an example of a modified stem of a plant. A modified stem of a plant is a stem that has been altered  over time to grow in another manner for a particular purpose. These purposes can be for defensive reasons or for objective reasons. In this case, the grapevine has stems that grow from the ground and extend in a curling manner to drape itself vertically/ horizontally on a solid surface. This helps the grapes receive adequate sunlight, room for growth, and  ground - danger prevention.

Autotroph

     On this magnificent tree, there are green algae present on the bark. This alga is an example of an autotroph. An autotroph is an independent organism that is capable of creating essential organic substances derived from inorganic substances. For example, the algae create their nutritional needs from the inorganic substance, carbon dioxide.

Hermaphrodite

     Here we have a beautiful rose. This rose is an example of a hermaphrodite. A hermaphrodite is any living being that acquires both male and female sexual organs and/ or characteristics. In this case, a rose is a plant that has both a male stamen and a female stigma in the center. These characteristics make it very plausible for an egg fertilization to take place within the flower's pollen.

C4 Plant

     This is a picture of wire grass. Wire grass is an example of a C4 plant. A C4 plant is one that converts carbon dioxide into a compound including four carbon atoms; this process takes place before the Calvin cycle of photosynthesis. Generally, these plants are a perfect fit for a warm and dry climates. 

C3 Plant

     In this picture, an evergreen plant is presented. It is an example of a C3 plant. A C3 plant is one that converts carbon dioxide into a compound that includes three carbon atoms; this process takes place before the Calvin cycle of photosynthesis. Typically, these plants are best suited for cool and humid climates.
