Then submit your completed lab report through the “Assignment” feature. This lab report is worth 50 points towards your final lab grade. Also‚ per the Honor Code‚ this work must be your own. CELLS Using your Biology Textbook answer the following questions. 1. What types of organisms are Prokaryotes? The Prokaryotes are organisms that are

simple cells surrounded by a membrane and a cell wall‚ with a circular strand of DNA containing their genes. They do not contain a nucleus or other internal structures that higher cells may have. These are called prokaryotes. Basically all the life you see today‚ including plants and animals‚ belongs to the third domain‚ Eukaryota. Eukaryotic cells are more complex than prokaryotes; the major difference between the eukaryotic and prokaryotic cells is the nucleus. The nucleus in a eukaryotic cell is

Eukaryotic & Prokaryotic Cells Introduction: The Cell: The cell is a functional unit of all living organisms. Cells have evolved into two fundamentally different types‚ eukaryotic and prokaryotic‚ which can be distinguished on the basis of their structure and the complexity of their organization. The simplest organisms which consist of one cell are called prokaryotes. More complex organisms are called eukaryotes and they consist of many cells. Objectives: * Define the terms: Eukaryotes

Prokaryotic and Eukaryotic Cells Cells are the basic building block of life. Cells can be either Eukaryotic or Prokaryotic cells. Organism can only contain either one but not both of them. Prokaryotic cells are usually much smaller than Eukaryotic and are less complex. Bacteria are made up of one or more prokaryotic cells. Bacteria are made up of one or more prokaryotic cells. While Eukaryotic cell are found inside plant and animal life. Eukaryotic are more advanced and larger. Prokaryotic cell were the

The eukaryotic cell cycle is the process that starts just as a cell is first formed from a dividing parent cell and then carried on until its own cell division (Simon‚ Dickey‚ Reece‚ page 125). The first stage involved in the eukaryotic cell cycle is called interphase. Interphase is the period between divisions that has 3 separate phases. The first phase in interphase is G1‚ where G stands for gap‚ and in this phase the growth of cell parts occurs and materials needed for transcription‚ translation

life’s hierarchy‚ cells make up the lowest level of organization. Cells can perform activities required to sustain life. A cell’s ability to divide to form new cells is the basis for growth and repair in organisms. Cells also play a key role in the recycling of carbon‚ a chemical element essential to life‚ and also participate in cellular processes such as photosynthesis. With these points in mind‚ it should be noted that cells come in one of two forms: prokaryotic and eukaryotic. By investigating

are made up of? If you answered cells‚ then you’d be correct. A cell is the smallest thing that can be alive‚ and all living things are made of cells! Cells are made of tiny organelles that work together to help the cells live‚ just like organs in our body keep us alive. You must also remember that there are two types of cells. Eukaryotic and Prokaryotic. The differences are simple; Eukaryotic cells are more complex and have more organelles while Prokaryotic cells are simple and have little organelles

Biology 1401 Dr. Erin 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

Bacterial cells are Prokaryotic cells. These cells have several internal structures and surface structures. The cell walls are of two types‚ gram positive and gram negative. Out of all the structures‚ the two selected structures are the cell- wall and endospores. The cell- wall of bacterial cells is found in three distinct shapes such as spherical‚ spiral and rod shaped. The cell wall of the bacterial cells is composed of the proteins and polysaccharides. This is collectively called peptidoglycan

compartments. Function: The plasma membrane in eukaryotic cells is responsible for controlling what goes in and out of the cell. Series of proteins stuck in the membrane help the cell to communicate with the surrounding environment it’s in. This communication can include sending and receiving chemical signals from other eukaryotic cells. Organelle: Cytoplasm Structure: Cytoplasm is a gel like substance which is located between the cell membrane holding all the cells organelles in place (except the nucleus)
