Sex Cells: Also known as Gametes, are the sperm cells in males and the eggs cells in females. These cells fuse in a process called fertilization , and the resulting cell (zygote) contains a mix of inherited genes from the father and mother. Germ Cells: Germ cells are cells involved in reproduction. The most well known examples of this type of cell are gametes. Gametes are the sperm and eggs which come together to create a zygote which can develop into a fetus. Somatic Cells: A Somatic cell is generally taken to mean any cell making up an organism. All cells of an organism are Somatic except Gametes. Cytology: The scientific study of cells. This includes their structures and their various functions. This role is generally attributed to Biologists. Extracellular Fluid: Fluid not contained in cells but found in blood, lymph, body cavities lined with serous membrane, channels of the brain and spinal cord, and in muscular and other body tissues.
Interstitial Fluid: A solution that bathes and surrounds the cells of multicellular animals. It is the main component of Extracellular fluid, which also includes plasma and transcellular fluid. The interstitial fluid is found in the interstitial spaces, also known as the tissue spaces.
Plasma Membrane: A thin, semi-permeable membrane that surrounds the cytoplasm of a cell . Its function is to protect the integrity of the interior of the cell by allowing certain substances into the cell, while keeping other substances out. It
1. Define science – Science is the development of concepts about the natural world , often by using the scientific method
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.e. two cells with a double set of chromosomes would fuse. Accordingly does meiosis produce haploid germ cells, with maternal and paternal germ cell fusing at fertilization and thus generating a
With sperm, each cell goes through meiosis to produce four sperm cells. During oogenesis a oogonium cell undergoes mitosis to produce primary oocytes. It differs from sperm formation because it is a stop-start process. It also divides the cell unequally and one primary oogonium cell produces one active cell in contrast to sperm.
Germ cells: the sexual reproductive cell at any stage from the primordial cell to the mature gamete
The concentration of dissolved substances is greater in the extracellular fluid than in the cytoplasm. Hypertonic Solution Concentration of dissolved substances (solute) Concentration of water (solvent) What happens to an animal cells? Inside the cell Less Greater Outside the cell Greater Less Membrane
There are two main types of cells in the world. The simplest cells such as bacteria are known as Prokaryotic cells, and human cells are known as Eukaryotic cells. The main difference between each of these cells is that a eukaryotic cell has a nucleus and a membrane bound section in which the cell holds the main DNA which are building blocks of life.
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.
The Female Reproductive System parts are gametes, which is a mature haploid male or female germ cell that is able to unite with another of the opposite sex in several reproductions to form a zygote. Egg is a person possessing a specified quantity. Ovum is a mature female reproductive cell especially of a human or other animal that van divide to give rise to an embryo usually only after fertilization by a male cell. Vaginal is a muscular tube leading from the external genitals to the cervix of the uterus in women and most female mammals. Labia is the inner and outer folds of the vulva, at either side of the vagina. Clitoris is a small sensitive and erectile part of the female genitals at the anterior end of the vulva. Urethra is a duct by
The fluid compartments include the extracellular fluid (ECF) and the Intracellular fluid (ICF) (Workman, 2013). The Extracellular fluid is comprised of the interstitial fluid or the fluid between the cells and the intravascular fluid or plasma (Workman, 2013). In total the extracellular fluid totals up to be approximately 15L of fluid
The plasma membrane is important to cells because it is a selectively permeable barrier which does
Lymph is a fluid that flows around the body tissue. The lymph contains a high concentration of lymphocytes (white blood cells).
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.
When the offspring mature and produces its own gametes, these gametes include equal proportions of the
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.
