# Cell Part Kingdom Analogy Why this analogy makes sense 1 Nucleus King The nucleus is the largest organelle and directs all cell activity‚ just like a king who controls and directs activity going on throughout the kingdom and is known as the biggest person in relation with power. 2 Nucleolus Peasants The nucleolus is the organelle which produces the ribosomes (farm) throughout the cell‚ just like the peasants who work hard to keep the farm fertile and running. 3 Ribosomes Farm The ribosomes

Chapter 2 IB Biology 2.1 Cell Theory 2.1.1 Outline the cell theory (2). • All organisms are composed of one or more cells • Cells are the smallest units of life • All cells come from preexisting cells • TOK: cell theory replaces the former ideas of spontaneous generation or abiogenesis in which inanimate matter assembles itself into living forms • Exception: muscle cells- more than 1 nucleus‚ very long; (fungal cells) hyphae roots- not a single unit; protoctista- not specialized to single

We believe that every child‚ no matter who they are or where they live‚ has the right to grow up safe‚ happy and healthy. In 1989‚ the world’s leaders officially recognised the human rights of all children and young people under 18 by signing the UN Convention on the Rights of the Child. The Convention is the basis of all our work. UNICEF is the only organisation working for children recognised by the Convention

real true and an honest relationship with oneself and others. To have an authentic relationship two people must have a genuine and strong bond with each other. The theory of authenticity is expressed by Sherry Turkle in her argument titled “Alone Together”. In Turkle’s argument she strongly believes that the best kind of relationships are authentic ones. Authentic ones can only be formed with intimate relationships and with people who share the same human experiences. She opposes the use of technology

Plant cells are eukaryotic cells that differ in several key aspects from the cells of other eukaryotic organisms. Their distinctive features include: A large central vacuole‚ a water-filled volume enclosed by a membrane known as the tonoplast maintains the cell’s turgor‚ controls movement of molecules between the cytosol and sap‚ stores useful material and digests waste proteins and organelles. A cell wall composed of cellulose and hemicellulose‚ pectin and in many cases lignin‚ is secreted by

How did the 9/11 bring people together? Or Did the 9/11 bring people together? The 9/11 was a very significant event and brought many people together in many different ways. In circumstances of extreme stress we hear moving accounts of people going out of their way to help each other. Studies show that acute stress can lead to greater cooperative‚ social and friendly behaviour‚ even in men. This more positive reaction can help the human connections that occurred during the time of crisis associated

Experiment title: Preparation of Biological Materials for Microscopic Examination Objectives: 1. To learn how to use a microscope. 2. To study the cell structure of starch grains‚ onion cells and cheek cells. 3. To differentiate the difference between starch grains‚ onion cells and cheek cells. Introduction: Microscope is an optical instrument use to magnify micro objects that hardly or impossible to be observed by naked eyes‚ so that the objects can be studied. Compound light microscope

regions of membrane lipids involved in cell signaling are called lipid rafts. • Hopanoids are sterol-like molecules found exclusively in bacteria. • Membranes from cells grown in media enriched with stearate are less fluid than normal membranes. This is because the membranes have more saturated fatty acids. • The functions of the biological membrane are : • They contain receptors for the detection of external signals • They provide a means of cell to cell communication • They regulate movement

How Does the Computer Work? Specific purpose: To inform and educate the audience about how the computer works. Central idea: The types of hardware that all computer systems use and the types of software that make them run. Attention Statement: Most of American families nowadays have at least one or more computer in their house. Computer has become a very important piece in our life. May be some people don’t realize it but we use computer almost every day. Like millions of computer users‚ microcomputers
