The life Process of a cell In my report you will learn about the life process of a cell based on the two main functions, metabolism and mitosis. You will learn about the essay on cells stages of essay on cells ingestion, digestion, respiration, and excretion, and how the cell completes them, essay on cells.

You also will acquire information about the four stages of mitosis: prophase, metaphase, anaphase, and telephase, and how the cell completes them. Mitosis is the process in which cells reproduce. These two processes are interdependent on each other. The steps of metabolism are the same for any species. First the cell must ingest glucose through active transport. The glucose is ingested through the cell membrane.

There are only 2 ATPs yielded in each glucose. An ATP is an energy enriched molecule. That is not enough energy to completely digest it. It is just enough energy to get it to the mitochondria. The enzymes in the mitochondria respire. Also now it has 34 ATPs. Then the lysosomes fully digest it.

Then the all the waste is excreted by the golgi bodies and vacuoles. The cell has fully metabolized. Now the process starts over. Mitosis is the process in which a cell divides into two new cells.

The four steps of mitosis are prophase, metaphase, anaphase, and telephase. The step where the cell prepares for mitosis is called interphase.

During interphase all of the chromosomes duplicate, and then are joined at the centrimere. Now mitosis begins, first in prophase all of the chromosomes then gather in the center of the cell, and the two centrioles go to opposite ends of the cell. Also the nucleic membrane breaks down. Next in metaphase the two centrioles create polymers called spindle fibers, that go across the whole cell.

For every chromosome there is a spindle fiber. The chromosomes attach them selves onto the spindle fibers, in the middle, or the equator of the cell. In anaphase the duplicated chromosomes separate from each other, and each chromatid goes to an end of the cell.

In the last step of mitosis, telephase the cell membrane breaks, and then closes off, leaving two new daughter cells. The two new daughter cells will go through same process. Cell metabolism, and cell mitosis are alike in a essay on cells ways. Both of the functions are completed in four main steps. A cell must do both of those things, essay on cells, essay on cells stay essay on cells. If a cell didnt metabolize, it could not reproduce. When a cell metabolizes it creates energy.

Part of that energy is used for the cell to reproduce. There are some cell parts that are used on both of the cell processes, such as the cell membrane. In metabolism food such as glucose, or lipids are ingested through the cell membrane, essay on cells. During mitosis the cell membrane will stretch, and break apart into two new daughter cells.

Cell metabolism and cell mitosis are two complicated processes that work naturally together, essay on cells.

It should be clear to you now the different stages of cell metabolism and cell mitosis. The stages of cell metabolism are ingestion, digestion, essay on cells, and excretion. The stages of cell mitosis are prophase, metaphase, essay on cells, anaphase, and essay on cells. More importantly, essay on cells, each stage has a definite and necessary job to create and sustain life.

Asexual reproduction What name is given to this process? To view the animation, click here. Then click on the image to start the animation. TermDefinition Interphase The cell has grown, new organelles essay on cells formed, and DNA has been replicated in the nucleus.

It is the longest phase of mitosis. Prophase The DNA condenses forming chromosomes. The nuclear membrane starts to dissolve, essay on cells, releasing the chromosomes into the cytoplasm. Metaphase The chromosomes line up in the middle of the cell. The nuclear membrance dissolves completely.

Anaphase Each chromosome separates into two identical single stranded parts. Essay on cells spindle fibers pull these daugher chromosomes toward each end of the cell.

Telophase Each chromosome separates into two identical single stranded parts. The spindle fibers pull these daugher chromosomes toward More than one celled organisms grow by way of mitosis and the cytoplasmic division of body cells.

On the other hand, meiosis occurs only in germ cells, which are put aside for the formation of gametes sperm and egg. Reproduction by meiosis allows for species survival and it increases genetic variability. The process, during which the germ cells are generated is called meiosis. It represents nature's solution to the problem of chromosome doubling that would occur, if two diploid cells, i.

two cells with a double set of chromosomes would fuse. Accordingly does meiosis produce haploid germ cells, essay on cells, with genetic material is exchanged between nonsister chromatids, resulting in new combinations of alleles.

During crossing-over, genetic material is exchanged between sister chromatids, resulting in new combinations of alleles. sister chromatids from each homologous chromosome of a essay on cells are exchanged, resulting in new combinations of alleles. nonsister chromatids from each homologous chromosome of a tetrad are exchanged, resulting in new combinations of alleles.

one homologous chromosome of a tetrad is exchanged with another tetrad, resulting in new combinations of alleles. the number of chromosomes is cut in half CellsCells are the basic unit of all life. Even though they are the smallestunit of life they are highly complex. Each cell has enough parts to it topractically survive on its own. There are two types of cells; the plant cell andthe animal cell. These two cells do not vary intensely, but there essay on cells somemajor factors that separate them completely.

Animal cells are highly organized. The many parts that make up the cellwork in synch with each other. These parts are called organelles. The mostimportant organelle in the cell is the nucleus. The nucleus holds all of theblueprint information for the TermDefinition chromatin one of a pair of duplicated chromosome Daughter cell Either of the two or 4 cells formed when a cell undergoes cell division by mitosis or meiosis. Mitosis A series of stages in the cell cycle of a somatic body cell in which the parent cell divides into 2 new daughter cells that are identical to the parent cell.

Cell division The process by which a cell, essay on cells, called a parent cell, divides to form either 2 or 4 daughter cells, essay on cells. Somatic cells Any cell of a sexually reproducing organism that is not a germ cell. Also called a 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. All cells are separated from their surrounding by a cell membrane. The cell membrane regulates what enters and leaves the cell and also aids in the protection and support Of the cell. A cell membrane is similar to the walls surrounding your house. In plants the cell membrane is surrounded by a cell My brother was studying for his biology test.

The next morning he was telling me about the dream he had. He said he traveled through a cell. I started to call him insane. My brother have an educational dream? I thought to myself, impossible.
