Compare and Contrast A plant Cell and an Animal Cell
There are many differences as well as similarities between plant cells and animal cells. First we will compare them. The cells of animal and plants have three basic structures. The first is they both contain cell membranes, which is also called the outer boundary of the cell. They also each have a nucleus, or control center. Cytoplasm is found in between the cell membrane and the nucleus of each cell also. They both also contain ribosomes, where the protein in the cell is made. Although they share many similarities, they are very unalike in dramatic ways.
To begin to contrast them, let me begin by saying they each are found in different things, obviously. The plant cell is located inside plans, as the animal cell is located inside animals (and people). The plant cell has an extremely larger vacuole than the animal cell. Vacuoles serve the purpose of storing water, salts, proteins and carbohydrates. In plant cells, the vacuole is usually filled with liquid. The pressure of the liquid filled vacuole in these cells makes it possible for the plant to grow quickly and support heavy structures such as leaves and flowers. The next difference is that the plant cell contains a cell wall and the animal cell just contains a cell membrane. The cell wall lies outside of the cell membrane. The cell wall helps to protect and support the cell. The cell wall has a lot of pores, so water, oxygen, carbon dioxide and things like that can pass through easily. The last major difference is that plant cells have chloroplasts, which make it possible for the plant to perform photosynthesis. This is because chloroplasts are organelles that convert sunlight into chemical energy. These contain the principle pigment in the cell that captures the light energy, as well as help it with its green color (the plant). As you can see, the plant and animal cells have many differences, yet if you think about it, they are all cells and parts of our daily life.
" We have studied both genetics and evolution in the past several weeks. Explain why evolution and genetics are so closely related."
The process by which modern organisms have descended from ancient organisms is the process of evolution. Genetics is the branch of biology that studies heredity, and heredity is the passing of traits from parents to their young. Evolution wouldnít make sense if we didnít know anything about genetics. Therefore, you can see how closely related they are because they go ďhand in handĒ.
When I refer to ďhand in handĒ, I mean that in order to understand evolution, you need to understand the whole process. During the process of evolution, you read about how numerous scientists think animals acquired the traits that they have, for example, why the giraffe has such a long neck, or why ducks have webbed feet. One way you could look at this, is that the traits donít just grow on these animals. They are passed on from parent to offspring. That is the genetics, the whole idea of it. That in itself is the process of heredity. That is how evolution and genetics are closely related.

CellsCells Cells are the basic unit of all life. Even though they are the smallest unit of life they are highly complex. Each cell has enough parts to it to practically survive on its own. There are two types of cells; the plant cell and the animal cell. These two cells do not vary intensely, but there are some major factors that separate them completely. Animal cells are highly organized. The many parts that make up the cell work in synch with each other. These parts are called organelles. The most

Some cells exist as single-celled organisms that perform all of the organism\'s metabolism within a single cell. Such single-celled organisms are called unicellular. Other organisms are made up of many cells, with their cells specialized to perform distinct metabolic functions. One cell within an organism may be
Changes in the Atmosphere Causing MulticellularityChanges in the Atmosphere Causing Multicellularity About 2.5 billion years ago, oxygen began slowly to accumulate in the atmosphere, as a result of the photosynthetic activity of the cyanobacteria. Those prokaryotes that were able to use oxygen in ATP production gained a strong advantage, and so they began to prosper and increase. Some of these cells may have evolved into modern forms of aerobic bacteria. Other cells may have become symbionts with larger cells and evolved into mitochondria. As t

Melatonin And The Pineal GlandMelatonin And The Pineal Gland Set deep in our brains is a tiny gland called the pineal gland. This tiny gland is in charge of the endocrine system, the glandular system that controls most of our bodily functions. The pineal runs our Ćbody clocks\', and it produces melatonin; the hormone that may prove to be the biggest medical discovery since penicilin, and the key to controlling the aging process. The pineal gland controls such functions as our sleeping cycle and the change of body temperature
What Are The Major Components of Biological MembraWhat Are The Major Components of Biological Membranes And How Do They Contribute To Membrane Function?. Summary. The role of the biological membrane has proved to be vital in countless mechanisms necessary to a cells survival. The phospholipid bilayer performs the simpler functions such as compartmentation, protection and osmoregulation. The proteins perform a wider range of functions such as extracellular interactions and metabolic processes. The carbohydrates are found in conjunction with both
MitochondriaMitochondria Mitochondria are responsible for energy production. They are also the responsible location for which respiration takes place. Mitochondria contain enzymes that help convert food material into adenosine triphosphate (ATP), which can be used directly by the cell as an energy source. Mitochondria tend to be concentrated near cellular structures that require large inputs of energy, such as the flagellum. The role of the mitochondria is very important in respiration. In the presence of o
MitochondrionMitochondrion Mitochondrion are the power plant of a cell. The mitochondria are cells based within a cell that turn nutrients from chemical form into a more simple and usable substance for a cell to use as energy. These sausage-shaped organelles are not a true organelle, but more of a parasite that invaded primordial cells and evolved along with them. A mitochondrianís main purpose is to burn energy through a slow method of combustion, which will consume as much air to burn as fire will, just to
The Process of MitosisThe Process of Mitosis Mitosis is the term used to describe cell division for replication. The product at the end of mitosis is two daughter cells both genetically identical to the original (parent) cell. This process (mitosis) is used for growth and repair within an organism (and also for asexual reproduction). There are five main stages to mitosis, called Interphase, Prophase, Metaphase, Anaphase and Telophase. Although the process has been divided up into these stages the process of mitosis i
Deoxyribonucleic acid and ribonucleic acid are twoDNA Deoxyribonucleic acid and ribonucleic acid are two chemical substances involved in transmitting genetic information from parent to offspring. It was known early into the 20th century that chromosomes, the genetic material of cells, contained DNA. In 1944, Oswald T. Avery, Colin M. MacLeod, and Maclyn McCarty concluded that DNA was the basic genetic component of chromosomes. Later, RNA would be proven to regulate protein synthesis. (Miller, 139) DNA is the genetic material found in most virus

Plant And Animal CellsPlant And Animal Cells I. Introduction All organisms in life are composed of at least one or more cells. Cells are the basic units of life. There are three main features of a cell. First, all organisms consist of one or more cells. Second, cells are the smallest units of life and third, cells arise only from preexisting cells. These three facts are referred to as the cell theory. All cells can be categorized into two basic cell types. They are prokaryotic and eukaryotic. To distinguish where cel

Next is the head that contains the genetic material for the virus. The genetic material for a virus is DNA. The two other parts are the tail sheath and the tail fibers that are used for odd jobs. I believe that a virus is not considered to be a living creature due to the fact it is a parasitic reproducer. To me it is just

One usually speaks of sex for reproduction, when actually sex and reproduction are the precise opposites of each other. Reproduction is the process by which one cell turns into two, sex is the process by which two cells turn into one. You may be thinking at this instant, which is better overall? Well, in terms of evolution, sex has had more of an advantage. Here\'s why: If two favorable mutations occur in different members of the population and they have sex,
