Diana Rubene LS2B Abstract The chloroplast is most commonly recognized for its vital role in plant cells & protist cells as their main provider of energy. Within this review we are going to discuss what exactly is chloroplast what structures make up this complex & super efficient organelle which is so important not only to plants & protists‚ but also to us. How exactly does it absorb and use solar energy and use it to produce carbohydrates rich with energy that can be passed down the food chain‚

are important to understanding cell injury and cell death regardless of the injuring agent” (Heuther & McCance‚ 2012). Cellular injury arises when a cell is unable to sustain homeostasis. The injury can be reversed if the cell can recover from whatever damage was done but if it does not recover the cell will die. The three common forms of cell injury are hypoxic injury‚ free radicals and reactive oxygen species injury‚ and chemical injury. The most common form of cell injury is hypoxic injury‚ or

Darwinian Snails Introduction All animals require a food source to survive‚ where and when they get their food is determined on availability and natural selection. Flat periwinkle snails are small marine snail that is part of the “Littorinidae” family. They are typically found on seaweed that grows off the shores of New England (Britannica). Predators bring out the best traits in a species which helps future generations. Periwinkle snails have several predators‚ but one of the main ones it the green

October 2014 Cell Division Mitosis Abstract Mitosis and Meiosis: Cells can be divided in unicellular organisms or in multi-cellular organisms. DNA controls the cell division. Bacteria reproduce by a process called binary fission. Bacteria have one chromosome that’s attached to the cell membrane. The chromosome replicates and the two copies separate as the cell grows. Over a period of time this one cell makes two cells. Eukaryotes do the process of mitosis. In mitosis‚ each daughter cell gets about

fundamentals of science. Title An investigation of an onion cell using a light microscope. Aim: The aim of this investigation is to identify the cells within an onion skin using a light microscope. An onion cell is a plant cell which through the light microscope‚ it should outline the cell wall‚ cell membrane and the nucleus. Introduction: Plant cells have a cell wall and cell membrane which animal cells do not have. The cell wall provides support and is relatively rigid‚ which consists of

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

ARISTOTLE Aristotle was Plato’s greatest student. One of his big contributions to philosophy was the theory of the four kinds of causes. Aristotle’s ideal state would be ruled by the virtuous citizens. Aristotle thinks that a state is an association for allowing each citizen to live well. What was Aristotle’s notion of friendship?
