BIO 202 L Dr.Simon Cytochemistry: Animal and Plant Tissues Lab Performed: October 4th‚ 2011 Lab Submitted: November 16th‚ 2011 Day in and day out; Scientist worldwide work closely with various cells to study their functions‚ their components‚ and their complex structures. In Bio 202 one way we’ve learned to examine a cell is by taking advantage of the differences within the chemical reactivity of the molecules located within (Lab Manual‚ Chp. 5). Major biological molecules such as Polysaccharides

Enzymes and their importance in plants and animals (25 marks) Enzymes are biological catalysts‚ which accelerate the speed of chemical reactions in the body without being used up or changed in the process. Animals and plants contain enzymes which help break down fats‚ carbohydrates and proteins into smaller molecules the cells can use to get energy and carry out the processes that allow the plant or animal to survive. Without enzymes‚ most physiological processes would not take place. Hundreds of

Report Title: Animal and Plant Cell Structures Instructions: Your lab report will consist of the completed tables. Label each structure of the plant and animal cell with its description and function in the tables provided. When your lab report is complete‚ post it in Submitted Assignment files. 1. Animal Cell: Observe the diagram showing the components of an animal cell. Using the textbook and virtual library resources‚ fill in the following table: Animal Cell

difference between plant and animal comes down to cell structure. Animal cells do not have cell walls and have different structures than plant cells. Plant cells only are in rectangular shapes but animal cells are either circular‚ irregular or defined shapes depending on the type of cell. Plants have 3 basic organs; roots‚ stems‚ and leaves. Plants lack a brain and all the organs that animals have to carry out metabolic functions as animals take their carbon from organic substances and plants take their

* NCERT 1. Reproduction in Organisms INTRODUCTION Biology in essence is the story of life on earth. While individual organisms die without fail‚ species continue to live through millions of years unless threatened by natural or anthropogenic extinction. Reproduction becomes a vital process without which species cannot survive for long. Each individual leaves its progeny by asexual or sexual means. Sexual mode of reproduction enables creation of new variants‚ so that survival advantage is enhanced
Premium Reproduction Gamete Reproductive system
ASEXUAL REPRODUCTION Asexual reproduction is a mode of reproduction by which offspring arise from a single parent‚ and inherit the genes of that parent only; it is reproduction which does not involve meiosis‚ ploidy reduction‚ or fertilization. The offspring will be exact genetic copies of the parent. A more stringent definition is agamogenesis which is reproduction without the fusion of gametes. Asexual reproduction is the primary form of reproduction for single-celled organisms such as the archaea

Scientific Name of Plants Ornamental Perennials The following is a list of the common plant names cross referenced to the scientific name of plants. The list represents some of the most popular varieties of perennial plants. The scientific names of plants is based on taxonomy‚ the science of plant classification. Each name has two parts‚ the genus and the specie. This is referred to as the binomial (two names)system founded by Linnaeus‚ a Swedish botanist. Some species will have a third name‚

Lab Report Comparing Animal and Plant Cells The cell is the fundamental structural unit of all living organisms. Cells help carry out the functions of life and together support the organism to function as a whole. Cells are divided into two main categories of eukaryotes and prokaryotes. Animal cells and plant cells fall into the division of eukaryote cells that have both a nucleus and organelles. In this lab‚ animal and plant cells will be compared through a microscope to identify differences

Title: To examine an animal and cheek cell using a compound microscope Date: 25th September 2012 Lab Partner: xxxxxxxxxxxxx Objective: The main aim of this experiment was to prepare a wet mount of human cheek cells and a wet mount of plant cells and examine them both under a compound microscope. Introduction: Cells are the basic units of life which make up every structure in the human body. They are the smallest units which are living. All cells contain different organelles which

Animal and Plant cells consist of most of the same cell types‚ but the whole shape of the cell is quite different. An animal cell is a round‚ uneven shape‚ whereas the Plant cell has an affixed shape. They have a more of a rectangular shape. Chloroplast‚ Vacuole and the Cell wall are only found in Plant cells. The Chloroplast is the organelle for the whole system of Photosynthesis. Chloroplasts are found in mesophyll cells (which are found in the leaves) of green plants. They convert light into
