ROOTS * is an organ of a plant that typically lies below the surface of the soil. * a part of a plant body that bears no leaves‚ and therefore also lacks of nodes. * is the beginning of the vascular system pipeline that moves water and minerals from the soil up to the leaves and fruits. FUNCTIONS OF ROOTS: * Underground (usually) * Anchor the plant in the soil * Absorb water and nutrients * Conduct water and nutrients * Food Storage ROOT SYSTEM: 1. Tap root system

SOME BASIC TIPS ON HOW TO WRITE A LAB REPORT Just searching on line will give you hundreds of examples so I just want to keep this really simple and basic and if you want to or need more explanation‚ just search the specific heading like “ How to write a conclusion on a lab report” and you will get more info than you ever wanted! Title Page • The title of the experiment. • Your name. • The name of the class. • The date the lab was performed or the date the report was submitted

Meiosis and Mitosis Meiosis vs. Mitosis: Meiosis requires two nuclear divisions‚ but mitosis requires only one nuclear division. Meiosis producers four daughter nuclei‚ and there are four daughter cells following cytokinesis; mitosis followed by cytokinesis results in two daughter cells. Following meiosis‚ the four daughter cells are haploid and have half the chromosome number as the parent cell. Following mitosis‚ the daughter cells have the same chromosome number as the parent cell. Following

100 CheckPoint: Mitosis and Meiosis Mitosis and meiosis are both important to a living organism because they represent cell divisions that are very important to every living organism because without cell division all living organisms would fail to reproduce‚ eventually dying out. Cell division plays a very important role in the life cycle of a cell. Mitosis and meiosis are important to living organism because they help living organisms to grow‚ develop‚ and reproduce. Mitosis is a type of asexual

Growth‚ repair and reproduction. • Growth: This is a result of mitosis. The more cells in an organism‚ the larger that organism is. Humans start off as one single cell‚ and by the time they are adults‚ they have over 10 trillion cells!!! This increase in the number of cells also allows for some of those cells to be specialized for various functions. This is important to the survival of many organisms. • Repair: This is a result of mitosis. If tissue is damaged‚ repair is extremely important. With

This article from The Onion addresses the way that today’s scientific research is conducted and makes fun of how the source of funding for an experiment can influence its results. Interpreted plainly‚ the article claims that a new step has been added the scientific method: after a hypothesis is made‚ funding must be found. Then‚ based on who is funding the research and the sponsor’s desire‚ researchers must then align their study so it gets the results the funders want. The organization in charge

How does mitosis produce new cells‚ and how is mitosis the same and different? Materials: - Compound microscope - Alliums root slide - Whitefish embryo slide - Power supply Procedure: Refer to page 48 and 49 in the textbook. Results: See attached sheet for drawings of my results. Discussion: Analyze and interpret question 1 and 2 on page 49. 1. The cells in the root tip region of the alliums differ quite a bit from the cells that are found deeper in the root. First of

Mitosis and Meiosis Purpose To understand the cell cycle and mitosis and how these two processes function within an organism. To understand meiosis and how this process produces gametes. Mitosis All cells in your body complete a cell cycle in which they grow‚ divide and‚ eventually‚ die. The cell cycle consists of four phases: G1‚ S‚ G2‚ and M (Figure 1). Each phase is associated with a specific cellular function: typically growth‚ synthesis‚ and division. The G1‚ S‚ and G2 phases comprise

Lab 8: Mitosis‚ Meiosis and the Cell Cycle . header Purpose: This activity is designed to familiarize you with the phases of mitosis and meiosis and compare these processes in a comparison chart. This activity will be three parts. For parts I and II‚ please scan your labeled work. Preparation: There is no preparation or materials needed for this activity. You will simply need access to a scanner to submit your work. Procedure Part 1: For this portion of the laboratory‚ please sketch a cell

Mitosis and Meiosis I. These two processes function to pass chromosomes from one cellular generation to the next in a very carefully controlled manner. II. Mitosis and Meiosis are both correctly described as nuclear division; they are never correctly called cell division‚ or any kind of reproduction. It is possible (and often quite normal) for nuclei to divide when cells don’t. And organisms reproduce; nuclei and cells divide. III. Mitosis A. Mitosis is the division of a nucleus
