The Function Of A Cell A Car

The function of a nucleus is that it controls nearly all the activities that is taken place in the body. The function of the nucleus is to help control all the activities inside the cell. Also the nucleus controls the cells growth and reproduction. Chromosomes Chromosomes are long threads of DNA and protein seen in a dividing cell. They contain the genetic material or genes.

There are many parts of a cell, they all have specific duties, and are all

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.

A cell is the basic unit of life, essential to maintaining the physiology of the larger organism. In animals, certain organelles metabolize food into energy, and then uses the energy for repair, growth and reproduction. Similarly, chloroplasts in plant cells transform sunlight into energy, a process known as photosynthesis.

* Cells allow things to go in and out of the organism (allows diffusion to happen so good things go in and bad things go out)

Nucleus – The nucleus is the largest organelle in the cell. It acts as the control system for almost all the activities of the cell. It stores the cell 's hereditary material, or DNA

The nucleus is the control centre of a cell. It contains genetic material such as DNA and controls the cell's growth and

Breaking down an organism leads scientists to identify cells. A group of cells create tissues, tissues combined are organs, and organs and their functions make up systems. Basically, cells make up living organisms. There are 2 kinds of cells: Prokaryotic and Eukaryotic. Within a prokaryotic, it doesn’t contain a DNA bounded nucleus; however, a eukaryotic cell does. Though the prokaryotic cell differs from a eukaryotic cell, they share a cell membrane. The cell membrane is composed of a phospholipid bilayer and proteins, which makes it selectively permeable. It is located outside of the cytoplasm and controls the movement of substances in and out of the cell. Its basic function is to protect the cell from its surroundings by selecting what can enter and exit the cell.

A cell membrane regulates what enters and leaves the cell. It is like a gate in a city because it regulates who comes in and goes out of the city. A nucleus is the control center of the cell. It is like a police department because the police control how everyone and everything acts. A ribosome synthesizes proteins for the cell. A ribosome is like a factory that produces stuff for construction workers. The ER synthesizes lipid membranes and proteins and transports stuff. It is like a manufacturing plant because it makes stuff just like the ER.

A cell can be compared to many things in life. We all have things around us that can work of the way cells do. I will be comparing a cell to a football team because a football team has many parts that can be compared and have similarities that they can be compared to one another.

Cells are some of the smallest organisms around. All living things consist of cells, and yet they are invisible to the naked eye. Cells are the basic structural and functional units of life. Cells are made up of many different parts which allow them to function properly.

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

The cell. The most basic form of life, and yet the most complex structure Mother Nature has to offer. For hundreds of years, man has tried to crack its codes, to try and find what makes it tick; but it seems that the deeper we go into the study of cells, the more questions appear too. The purpose of this entire essay is to educate my readers on cells, our discovery of cells and the cell theory, where we believe they first appeared, and how we have learned to manipulate cells to cure diseases like cancer. I will also talk about how our knowledge of cells has changed our medicine and agriculture, and how ethnic some of these changes are.

Organelles are the internal structures of the cell that are important for the cell to survive. Each organelle has a specific function for the cell. The types of organelles in the cell can be different from each other depending on the type of cell. Plant cells and animal cells both have a cytoskeleton, endoplasmic reticulum (smooth and rough), golgi apparatus, mitochondrion, nucleus, plasma membrane, and ribosomes. Animal and plant cells also have vacuoles, but they are rarely found in animal cells. Vacuoles in animal cells are very small compared to the vacuoles in plant cells. Lysosomes are also rarely found in plant cells but mostly found in animal cells.
