Modified Leaf of a Plant (example 2)

This is a picture of bougainvillea.  The colored parts of bougainvillea are modified leaves called bracts, which resemble petals.  Although they are colored like petals to attract pollinators, they still retain the functions of a leaf.  As seen in the picture, the bracts still have veins for water and nutrient transport.  

 

 

Tropism

Tropism is the response, in terms of plant growth, to a biological stimulate.  The plant pictured above exhibits heliotropism, or growth relative to sunlight.  As the plant grew out of its pot, the shoots started to bend upward towards the sun.  This is also sometimes called phototropism, or growth in response to light.

Autotroph

An autotroph is an organism that produces its own food.  A plant, such as the one in the picture, use photosynthesis to produce their food.  In the process of photosynthesis, plants use carbon dioxide, water, and light to produce glucose and oxygen.  The main purpose of photosynthesis is produce sugars; oxygen is produced as a byproduct.

Cuticle Layer of a Plant

The cuticle layer of a leaf is the waxy, waterproof covering over the leaf.  In the picture, it is the shiny surface of the leaf.  The main purpose of the cuticle is to retain water.  The cuticle also functions as a protective covering

Hermaphrodite: Jellyfish

In the photograph above, numerous jellyfish explore the inside of an aquarium tank (The green tint is from a light that changes color periodically in the tank). Jellyfish are commonly known as a hermaphroditic species. Hermaphrodites are organisms that typically possess the reproductive organs of both the male and female sexes. These hermaphroditic species do not have a defined male and female character. During sexual reproduction, the hermaphroditic organisms can act as either the male or female during the process. Commonly known hermaphrodites are certain species of fish, some snails, most plants, and many more. In zoology, some scientists and researchers also define a hermaphrodite as a species that is born to one sex but later on in life, transforms to another sex. Again, this is common in many species of fish. This definition varies from organisms that carry both male and female gonads.

Genetic Variation within a Population

Genetic variation describes naturally occurring genetic differences among individuals of the same species. Genetic variation is brought about by mutation, which is a change in the chemical structure of a gene.
Fingerprints are actually a neutral genetic variation. Every individual in the human species has their own distinct fingerprints pattern making it a variation among the population.

4#3 Types Of Carbohydrates: Oligosaccharides

Oligosaccharides are carbohydrates composed of a few monosaccharides, about two to ten. they can have many functions including cell-recognition on plasma membranes of animal cells. They are usually found linked to compatible amino acid side chains in proteins or to lipid moieties. It is also most frequently found within plants in large amounts in chicory roots, onions, wheat, legumes, asparagus and more.

Epithelial tissue

 

Epithelial tissue covers the whole surface of the body as well as internal body surfaces. Epithelium can be divided into two groups: simple or stratified. Simple is one cell thick, stratified is two or more. Epithelial tissue has multiple functions, these include: protection, sensation, secretion, absorption in the intestines, excretion of sweat, diffusion in the lungs, cleaning the airways, and reducing friction in blood vessels.

Anther and filament of stamen

 

The stamen is the pollen-producing organ of a flower. The stalk is known as the filament, and the tip is known as the anther. The anther contains the microsporangia. The anther can be attached to the filament in two ways: basifixed or versatile. Basifixed means the anther is attached at its base to the filament, while versatile means it is attached at its center to the filament.

Auxin producing area of a plant

Auxin is a plant hormone found in the stem tip. This hormone can cause leaf production as well as cause exhibition of phototropism. On a cellular level, auxin is necessary for cell growth. It affects both cell division and cellular expansion and contributes to cell differentiation and specifies the fate of the cell ie) whether the cell should die or continue to grow. Auxin also induces the formation of xylem and phloem.
