CHAPTER ONE ANATOMY - Studies the STRUCTURE of body and their relationships to one another. SUBDIVISIONS OF ANATOMY GROSS ANATOMY - the study of large body structures visible to the naked eye. Regional Anatomy - all structures in one part of the body are studied at the same time Systemic Anatomy - various systems of the body are studied. MICROSCOPIC ANATOMY - examination of body tissue using a microscope. CYTOLOGY - study of the CELLS of the body. HISTOLOGY - study of the TISSUES

PLASTIDS Plastids are large cytoplasmic organelles. Plastids are major organelles found in the cells of plants and algae. Plastids are the site of manufacture and storage of important chemical compounds used by the cell. Plastids often contain pigments used in photosynthesis‚ and the types of pigments present can change or determine the cell’s colour. The term plastid was derived from the Greek word plastikas meaning formed or moulded. This term was coined by Schimper in 1885. In plants

Chapter 5 Assignment 1. What is energy? What are the three forms of energy? Energy is the capacity to do work. There are four types of energy according to the powerpoint. They are Kinetic energy (energy of motion)‚ potential energy (stored energy)‚ thermal energy (heat)‚ and chemical energy (potential energy of molecules). 2. State the First and Second Laws of Thermodynamics. Include entropy in your explanation. The first law states that energy can neither be created nor destroyed it can

ChApter 5 Lipids ChApter oBJeCtiVeS Chapter 5 is designed to allow you to: 1. List four classes of lipids (fats) and the role of each in nutritional health. 4. Explain how lipids are digested and absorbed. 2. Distinguish between fatty acids and triglycerides. 5. Name the classes of lipoproteins and classify them according to their functions. 3. Differentiate among saturated‚ monounsaturated‚ and polyunsaturated fatty acids in terms of structure and food sources. 6. List the function of lipids‚ including

The tonoplast is identical to the cell surface membrane except it surrounds only the vacuole‚ compared to the cell surface membrane which surrounds the entire cell. A plasma membrane is made up of a phospholipid bilayer. Each layer which consists of a hydrophobic fatty acid tail and a hydrophilic phosphate head.

their boundaries. They are composed of a bilayer of phospholipid molecules interspersed with protein molecules. Most membranes also contain very small amounts of carbohydrates that are usually associated with the phospholipids or proteins. (Danyk‚ 2013/14) Phospholipids in the membrane are composed of a phosphate group‚ glycerol backbone and 2 fatty acid chains. They are amphipathic; each has a hydrophobic region and a hydrophobic region. The nonpolar lipid tails are hydrophobic and the polar phosphate

Should Bacteria and Archaea belong to the same Kingdom? The main purpose of this essay is to find out if Archaea and Bacteria should be classified as two different Kingdoms or as a single one. As organisms‚ bacteria and archaea both are microscopic and prokaryotic (not possessing a true nucleus). These prokaryotes are very abundant on Earth and inhabit a wide spread of areas‚ including extreme ones. Both are an example of the most ancient living cells‚ which have appeared over 3.5 billion years
