Nucleus: The nucleus is the largest organelle in most cells. It controls eating, movement and the reproduction of the cell. The nucleus holds all the DNA information of the cell. Surrounding the nucleus is a double membrane called the nuclear envelope. The nuclear envelope holds the nucleus together and makes sure it keeps everything inside the nucleus.
Mitochondrion: The job of the mitochondria is to break down nutrients and turn them into energy to power the cell. They constantly work to keep the cell full of energy. It works by keeping the mitochondria full of water and proteins. It then takes organic molecules and chemically digests it. After the chemical reaction, it releases water and carbon dioxide.
Cell Membrane: The cell membrane
The main function of the mitochondria is to convert fuel into a form of energy the cell can use. Specifically, the mitochondria is where pyruvate --derived from glucose-- is converted into ATP (Adenosine triphosphate) through cellular respiration. Cellular respiration involves four stages: glycolysis, the grooming phase, the citric acid cycle, and oxidative phosphorylation. The final two stages listed occur in the mitochondria.
Essentially, the nucleus is vital for the cell’s survival. The nucleus controls and gives instructions to all organelles and inhabitants of the cell(Doc. 2). It is a dense, ball shaped configuration that contains the DNA of the cell.
Cells are a highly complex entity and is both structurally and functionally the basic unit of all living things. Cells are an important and vital part in order to sustain life. Cells are highly diverse and their specific roles are dependent on shape and internal composition. Cells are what carry out functions to promote life, including: reproduction, nutrient digestion, and metabolism. The cell has many components including the nucleus, cytoplasm, many organelles, and a plasma membrane. The nucleus contains all of the genetic material and genes, which are found in the DNA. The nucleus is the control center of the cell as it is key for cell reproduction. The nucleus is surrounded in a membrane called the nuclear envelope for protection and regulation of materials in and out of the nucleus. Cytoplasm is what all of the cell contents is referred to outside of the nucleus. This includes all the high specific metabolic machinery called organelles. A list of organelles include: Ribosomes, endoplasmic reticulum, Golgi apparatus, lysosomes, peroxisomes, mitochondria, and centrioles. Ribosomes are free floating spherical bodies of RNA and proteins which are the site for protein synthesis. Endoplasmic reticulum is broken into two structures, the rough and smooth endoplasmic reticulum. Rough ER provides area for storage and transport of proteins
The nucleus is the control centre of a cell. It contains genetic material such as DNA and controls the cell's growth and
The mitochondria is an organelle of a cell. It works as it was the digestive system, it’s in charge of obtaining the nutrients, then break them down, and finally, all that work is for maintaining the cell full of energy, so they would be as the power plants of the cell. The mitochondria are in charge of creating 90% of the energy that our bodies need so it can sustain life and support our growth. The mitochondria are small organelles that floats all through the cell. Some cells have many, lots of mitochondria, but others just have none; for example, the muscle cells need a lot of energy, so they contain lots of mitochondria, otherwise, neurons don’t need as much. Depending of the quantity of energy that the cell needs, mitochondria could be created.
The Nucleus has a sphere-shaped body that encloses a variety of organelles, including the nucleolus, and is home to the deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) of a cell inside the chromosomes. It is typically seen as the largest part of the animal cell. The nucleus controls many of the functions and activities inside an animal cell, and is known as the “control centre” of a cell. On the diagram, the nucleolus can be located as the black dot in the middle of the Nucleus, and is the main site for ribosome formation.
Mitochondria are rod-shaped organelles that can be considered the power generators of a cell. They convert oxygen and nutrients into ATP. In turn, ATP powers most of the cell’s chemical reactions that allow the cell to function. Without mitochondria, certain cells would not be able to work and do their job. The cells would not be able to obtain enough energy to survive. A cell’s mitochondria relates to workers because they supply the cell with energy, just like how workers supply their energy to do their job. The mitochondria in a cell are responsible for providing energy so the cell can function, like how workers do certain tasks to keep the business thriving. Mitochondria are found in both plant and animal cells. However, they are found in
The mitochondria is known as the “power house” of a cell that functions at the site of respiration. Within the inner membrane, ATP synthesis occurs which provides energy to the cell and it other parts. Without function of a mitochondria, a cell would die; it has no energy to repair itself, has no energy to transport molecules across the membrane, transport nutrients, send signals to other cells, or any other processes. Metabolism, release of energy, movement, or forming new nucleotides would not occur simply because energy is not available.
There are several different organelles which allow the cell to carry out its function which is reproduction and growth. There are important organelles that the eukaryotic cell needs, one of which is that the nucleus is present. The nucleus acts as the brain of the eukaryotic cell. DNA is found in the nucleus which holds all the genes and also controls the cell. The cells function is to reproduce, which needs the nucleus to do this. To carry out another function which is to reproduce, the chromosomes which are found in the DNA are needed and copied. The cell also needs a lot of energy for this. The energy is created by the eukaryotic cell’s other organelle which is mitochondria. The mitochondria make energy out of food and then give the cell the energy it needs to carry out its function. The lysosome then digests enzymes which breaks down the
Every living cell is surrounded by a thin layer known as the cell membrane or plasma membrane, which controls the movement of substances in to and out of the cell. This membrane is also responsible for maintaining the ultra-structure of the cell, and keeping its internal components together. Organelles such as the nucleus, lysosomes, the Golgi body and mitochondria are also bound by their own individual membranes.
Mitochondria: a word many people have used in their vocabulary, but one that most people fail to understand. Why is the mitochondria famously known as the powerhouse of the cell? It is because of its energy production. The mitochondria is responsible for the large majority of the production of ATP(adenosine triphosphate for those who actually care). ATP is the molecule that provides energy for most of the body’s functions. This organelle also aids in the processes of cellular differentiation(the changing of one cell type to another) and cell death(literal programmed, predetermined death of a cell). The mitochondria is made up of several different regions that help the organelle to function properly. These regions include the outer membrane,
The cytoplasm is the area between the nucleus and the cell membrane. The cytoplasm contains many important structures. This area is basically the main place where you will find structures that help the cells stay alive.
Mitochondria is one of the main organelles inside a cell. It is considered the energy factory and has many functions all over the cell. Its main purpose is to make ATP, or adenosine triphosphate. ATP is the energy that every cell in the body can use to stay alive and continue each individual function. “Mitochondrion is a combination of the Greek words mitos (thread) and chondros (granule)” (van der Giezen). “Mitochondria are eukaryotic, membrane-enclosed, 1-10um sized organelles, described as ‘cellular power plants’ as they are responsible for the production of adenosine triphosphate (ATP) and oxidative phosphorylation” (Mulchandani). The Mitochondria interacts with other places in the cell by giving them energy to perform their functions.
In order for cells and organisms to “live” they need to perform certain tasks such as produce energy through respiration, send messages, maintenance and reproduction. To enable the cell to do so, it contains within small structures called organelles, each organelle is different and carries out a specific function.
Nucleus- “the brain” or control center of the cell. The Nucleus, a membrane-bound structure of a cell, plays two crucial roles in controlling the cell. The nucleus carries the cell's genetic information that determines if the organism will develop, for instance, into a tree or a human; and it directs most cell activities including growth, metabolism, and reproduction by controlling protein synthesis. The presence of a nucleus distinguishes the more complex eukaryotic cells of plants and animals from the simpler prokaryotic cells of bacteria and cyanobacteria that lack a nucleus. The nucleus is the most predominate structure in the cell. It is typically round and occupies 10% of the cells total volume. The nucleus is wrapped in a
