Prokaryotes explanation

Explanation:

Prokaryotes are single-celled organisms that are the earliest and most primitive forms of life on earth. As organized in the Three Domain System, prokaryotes include bacteria and archaeans. Some prokaryotes, such as cyanobacteria, are photosynthetic organisms and are capable of photosynthesis.  

Many prokaryotes are extremophiles and can live and thrive in various types of extreme environments including hydrothermal vents, hot springs, swamps, wetlands, and the guts of humans and animals (Helicobacter pylori).

Prokaryotic bacteria can be found almost anywhere and are part of the human microbiota. They live on your skin, in your body, and on everyday objects in your environment.

Prokaryotic Cell Structure

Prokaryotic cells are not as complex as eukaryotic cells. They have no true nucleus as the DNA is not contained within a membrane or separated from the rest of the cell, but is coiled up in a region of the cytoplasm called the nucleoid.

Prokaryotic organisms have varying cell shapes. The most common bacteria shapes are spherical, rod-shaped, and spiral.

Using bacteria as our sample prokaryote, the following structures and organelles can be found in bacterial cells:

Capsule: Found in some bacterial cells, this additional outer covering protects the cell when it is engulfed by other organisms, assists in retaining moisture, and helps the cell adhere to surfaces and nutrients.

Cell Wall: The cell wall is an outer covering that protects the bacterial cell and gives it shape.

Cytoplasm: Cytoplasm is a gel-like substance composed mainly of water that also contains enzymes, salts, cell components, and various organic molecules.

Cell Membrane or Plasma Membrane: The cell membrane surrounds the cell's cytoplasm and regulates the flow of substances in and out of the cell.

Pili (Pilus singular): Hair-like structures on the surface of the cell that attach to other bacterial cells. Shorter pili called fimbriae help bacteria attach to surfaces.

Flagella: Flagella are long, whip-like protrusions that aid in cellular locomotion.

Ribosomes: Ribosomes are cell structures responsible for protein production.

Plasmids: Plasmids are gene-carrying, circular DNA structures that are not involved in reproduction.

Nucleoid Region: Area of the cytoplasm that contains the single bacterial DNA molecule.

Prokaryotic cells lack organelles found in eukaryoitic cells such as mitochondria, endoplasmic reticuli, and Golgi complexes. According to the Endosymbiotic Theory, eukaryotic organelles are thought to have evolved from prokaryotic cells living in endosymbiotic relationships with one another.  

Like plant cells, bacteria have a cell wall. Some bacteria also have a polysaccharide capsule layer surrounding the cell wall. This is the layer where bacteria produce biofilm, a slimy substance that helps bacterial colonies adhere to surfaces and to each other for protection against antibiotics, chemicals, and other hazardous substances.

Similar to plants and algae, some prokaryotes also have photosynthetic pigments. These light-absorbing pigments enable photosynthetic bacteria to obtain nutrition from light.

Binary Fission

Most prokaryotes reproduce asexually through a process called binary fission. During binary fission, the single DNA molecule replicates and the original cell is divided into two identical cells.

Steps of Binary Fission

Binary fission begins with DNA replication of the single DNA molecule. Both copies of DNA attach to the cell membrane.

Next, the cell membrane begins to grow between the two DNA molecules. Once the bacterium just about doubles its original size, the cell membrane begins to pinch inward.

A cell wall then forms between the two DNA molecules dividing the original cell into two identical daughter cells.

Although E.coli and other bacteria most commonly reproduce by binary fission, this mode of reproduction does not produce genetic variation within the organism.  

Prokaryotic Recombination

Genetic variation within prokaryotic organisms is accomplished through recombination. In recombination, genes from one prokaryote are incorporated into the genome of another prokaryote.

Recombination is accomplished in bacterial reproduction by the processes of conjugation, transformation, or transduction.

Capsule, cell wall, cell membrane, pilus, flagella, ribosomes, nucleoid, and plasmids are the parts of prokaryotic cells.

Single-celled creatures known as prokaryotes are the earliest and most basic living forms on Earth. Bacteria and archaeans are prokaryotes, which are classified according to the Three Domain System. Some prokaryotes are photosynthetic creatures and can do photosynthesis, such as cyanobacteria.

Prokaryotic bacteria are ubiquitous and comprise a significant portion of the human microbiome. They exist on your skin, inside your body, and on commonplace items in your surroundings.

Bacteria, as a sample prokaryote, its cells have the following organelles and structures:

Therefore, the capsule, cell wall, cell membrane, pilus, flagella, ribosomes, nucleoid, and plasmids are the parts of the prokaryotic cells.

This makes it important to use instruments that can detect different wavelengths of light to help us to study the Earth and the Universe. However, since visible light is the part of the electromagnetic spectrum that our eyes can see, our whole world is oriented around it.

Answer:

As average temperatures at the Earth's surface rise, more evaporation occurs, which, in turn, increases overall precipitation. Therefore, a warming climate is expected to increase precipitation in many areas.

Answer:

Due to newly formed land.

Explanation:

Surtsey provided ideal conditions for studying primary succession because due to volcanic eruption all the vegetation and living organisms are destroyed from the surface and the land has no vegetation. Primary succession only occurs when the land is colonized for the first time after the formation of land due to natural disaster such as volcanic eruption etc. So we can say that Surtsey provided the conditions for observing primary succession.

According to the Dalton's theory, carbon and oxygen are different elements because they are made up of different atoms which have different numbers of proton and neutrons.

John Dalton proposed his modern theory of atoms in 1803. He discovered atom, which is the smallest unit of particle. This theory is also known as the atomic theory of matter.

In this theory, he stated that every single atom of an element, such as sodium, is same as the other atoms of the same element. He also stated that the atoms of one element differ from the atoms of other elements. This theory is mostly found to be true. For example: A sodium atom is different from a carbon atom.

However, his theory was found to be found as the atoms present in the elements are found to be divisible into even smaller particles like protons, neutrons, and electrons.
