Zach Sexton December 4‚ 2014 Bot 121 Lab Coleus Lab Report 1. A cutting can form an entire new plant if cutting being used has a meristem. If the cutting has no meristem‚ mitosis will not occur and you will end up with a dead piece of plant material. In order to successfully grow a new plant through a cutting‚ your plant must have adventitious root growth which in order to deliver water and nutrients to the plant. Adventitious roots are created through cell potency where cells differentiate. The

Lalin Candium Lab Report Chemistry Block H Mr. Neil Chipman Calculating the Atomic Mass for Different Candium Isotopes Objective: In this experiment I will be discovering the atomic weight of Candium isotopes. By doing this experiment‚ it helps us to know how to calculate the relative abundance and atomic mass of each Candium isotopes without having to use the spectrometer. This lab will achieve my understanding of isotopes and why it has different masses but same number of protons due

First‚ we obtained a test tube rack and 9 test tubes. We had three unknown solutions‚ A‚ B‚ and C. We filled 3 test tubes with the solution A‚ the next 3 with solution B‚ and the last 3 with solution C. The first set of three test tubes A B C we drops few biuret reagent into it‚ then we gently shake the test tubes‚ and observed the test tubes for color change. In the next set of 3 test tubes A B C we put a few drops of Benedict solution into it and we gently shake the test tubes back and forth

Interphase: DNA has formed already‚ but it remains in the simple form of chromatin. Chromatins are structures that are loosely coiled in the cell.3 I also observed during my lab that this was the only stage where I could still see a nucleus and nucleolus intact within the cell; this is because it’s the only stage where the nuclear membrane has

Natasha Tenen Lab: Thursday (3-6 pm) OSMOSIS LAB REPORT INTRODUCTION Osmosis is a special type of diffusion where water molecules move down a concentration gradient across a cell membrane. The solute (dissolved substance) concentration affects the rate of osmosis causing it either to speed the process up or slow it down. Based on this‚ how does different concentrations of sucrose affect the rate of osmosis? If sucrose concentration increases in the selectivity-permeable baggies‚ then the

Measure and record the depth of the H2O2.Place 1 vial in the 0°C bath and leave 3 at room temperature. This is necessary because heat will destroy the hydrogen peroxide. 4. Allow the catalase and substrate to incubate at each temperature for about 5 minutes‚ then test the reaction time at each temperature by dipping a filter into enzyme at the
