Nucleus- The nucleus is the control center of the cell. This is where DNA is contained. This is like the town hall or the mayor’s office because it is the control center of a town. The nucleus uses DNA like a city uses blueprints to direct the production of protein. Nucleolus- The nucleolus is where ribosome is made and is rich in RNA content. It is located inside the nucleus. A mayor is like this because the mayor makes everything in the town happen. He also works from the town hall‚ or works

Schuenzel February 13‚ 2014 Bacterial and Eukaryotic Cell Structures All organisms are composed of cells which are characteristically microscope in size. Cell size is limited by the efficiency of diffusion across the plasma membrane. A typical eukaryotic cell is 10 to 100 micrometers in diameter opposed to prokaryotic cells are 1 to 10 micrometers in diameter. Bacterial and Eukaryotic cells display different cell organization in their size and structure‚ but despite this all they display basic structural

artery carries blood from the aorta to the kidney. The nephron has a cup-shaped nephric capsule that surrounds a cluster of capillaries called the glomerulus. A good deal of fluid from the blood filters into the capsule. Large proteins and whole blood cells are left behind due to the fact that their too big to pass through the filters along with the plasma or blood fluid. There are four main parts of the nephron tubule: the proximal convoluted tubule‚ the U-shaped loop of Henle‚ the distal convoluted

Biology – Assignment One Cells. Question One Explain the roles of the main components and features of a cell to the cell function. A typical animal cell is rounded in shape‚ surrounded by a cell membrane. This holds in the cytoplasm‚ which contains other structures such as the nucleus‚ ribosomes‚ and mitochondria. Each cell has tiny structures inside called organelles; each type of organelle performs a particular function. For example there are mitochondria (power stations)‚ ribosomes (protein

John Leone Lab Partner(s) Ethan Davis & Ryan Hanna Date: 12/10/14 Instructor: Dr. Chuckran Period: H Plants and Animal Cells Abstract: In this lab‚ you will find out how plant and animal cells are alike and how they are different. The onion elodea cells were both plants‚ so they had a cell wall. The cheek cells were animal cells‚ so they did not have a cell wall. Eukaryotic cells contain structures called organelles that carry out life processes. Eukaryotic cells can be classified by the types of organelles they contain

Hammurabi. Hammurabi ruled in Babylon‚ from 1792- 1750 B.C.E. The Code of Hammurabi which is the first written set of laws known to mankind‚ set the stage for all laws written‚ even today. You may ask why do we need laws in our society? The meaning‚ and function of laws in a democratic society is to establish rule of conduct‚ protect the rights and freedoms of citizens‚ and to provide protection for society. In society we live with‚ and interact with others‚ and we need laws to stop‚ and to control unavoidable

They all work together to keep all your organs and tissues inside your body it also keeps infection‚ viruses and bacteria out of your inside of your body. In your skin cells there are little thing to tell the cell what to do. There is a nucleus is the control center of the cell. There is a cell membrane it the holder‚ so
