CELL AND DEVELOPMENT part 1

MODEL ORGANISM

Canorhabditis elegans (nematode worm) is the model organism chosen. It is an organism that is used for genetic research because of their size and short generation.Their increased number in progency also helps in being well suitable for doing research on them. It is important for cell biology,aging and neuroscience. Canorhabditis elegans is mostly a model organism for aging for the investigation of animal development. It is mainly used because it is simple and easy to grow in bulky populations.

ImageI AM A GERM CELL

I AM FOUND IN THE REPRODUCTIVE ORGANS AND GERMLINE TISSUES

Canorhabditis elegans is about 1mm long and consists of about 1000-2000 germ cells, exactly 959 somatic cell nuclei plus about 2000 germ cells, are counted in one sex. Being one of those germ cells i actually originate near the gut of the embryo in the nematode. Then I migrate to the developing gonads where I undergo cell division, mitosis and meiosis into gametes.

ImageThe purpose I was given is to produce gametes when they are needed in the body of the nematodes. Also I am the only cell that can undergo both mitosis and meiosis. When i get older I hope to become a healthy cell that will carry out my responsibilities and be the best cell I can be. My fate is to determine the sex of the nematode I am located in and produce gametes so it would be able to reproduce someday.

I am a circular cell structure that can fit into places that I am needed. I consist of a nucleus, mitochondria,nucleolus,endoplasmic reticulum, cell membrane , lysosome and more. The purpose of the mitochondria in my body is to help generate ATP which is needed for energy. This allows me to carry out my functions without getting tired. The nucleus helps to control cell growth and reproduction. The rest of the oraganelles inside me all play an important role to help me stay alive and continue with my job.

INTRODUCTION TO CELLS

Cells are the smallest unit of structure and function of all plants and animals. It is capable of  integrating the essential life processes.

cells are separated into two groups prokaryotic and eukaryotic cells.

Image

The common features of prokaryotic and eukaryotic cells are:

1. DNA, the genetic material contained in one or more chromosomes and located in a nonmembrane bound nucleoid region in prokaryotes and a membrane-bound nucleus in eukaryotes

2. Plasma membrane, a phospholipid bilayer with proteins that separates the cell from the surrounding environment and functions as a selective barrier for the import and export of materials

3. Cytoplasm, the rest of the material of the cell within the plasma membrane, excluding the nucleoid region or nucleus, that consists of a fluid portion called the cytosol and the organelles and other particulates suspended in it

4. Ribosomes the organelle where protein synthesis takes place.
