Purpose: How will salt and plain water affect plant cells? Hypothesis Clear water: If you place carrots and celery in plain water they will become flaccid and then eventually start to loose its colour and pieces of the celery or carrots will fall off. I know this because the vegetables will continue absorbing water putting the vegetable in a hypotonic solution. Pieces of the vegetable could break off because the cells are not getting what they need. The cells need to create glucose and oxygen

1. For this experiment‚ what were the independent variable and the dependent variable? What were the constants? The environmental factors that you are testing on the rate of transpiration are the independent variable of this experiment. These independent variables are specifically light‚ fan‚ dark‚ and humidity. The dependent variable is the rate of transportation because this depends on whatever environmental factor the plant is placed. The constants are things like the type of plant used‚ room

Christine Otieno Estimating Osmolarity of plant Cells(potato and celery)by percentage change in weight Using different sucrose concentrations Introduction The purpose of this experiment was to estimate Osmolality of plants cells i.e. Potato and celery by converting the observed change of weight in different sucrose concentrations. The hypothesis assumes that the solute concentration of the plant samples would be indirectly proportional to the weight; there would be decrease

The Effect of Light Intensity on Photosynthesis and Transpiration Inna V. Raymundo BOTANY I Section V-6L August 29‚ 2012 ¹A scientific paper submitted in partial fulfillment of the requirements in Botany I laboratory under Dr. Nonnie Bautista‚ 1st sem‚ 2012-2013. ABSTRACT Photosynthesis and transpiration both play important roles in plants. But there are factors which affect the rate of photosynthesis and transpiration. The external factor that was identified is the light

The Death of Abdulla the Camel Driver Introduction: Before we explore the conditions surrounding Abdulla’s death‚ let’s review some basic facts. We define diffusion as movement of materials from a region of higher concentration to a region of lower concentration. This movement is due to kinetic energy of particles. An example of this can be observed by opening a bottle of perfume. Soon you will smell the perfume in distant parts of the room. It diffuses from the high concentration

PAPER 3 Answer all question. Question 1 Transpiration is the evaporation of water vapour from the leaves surface. Air movement is one of the factor that affects the evaporation of water vapour. A group of student carried out an experiment to study the effect of air movement on rate of transpiration of plants. Diagram 1 shows the apparatus used by the students. The experiment was conducted under still air and strong fan speed. Diagram 1 The time taken for the air bubble in the capillary tube to

consumptive use of water is related to evapo-transpiration by a coefficient called crop coefficient‚ which depends on type of crop and its growing stage. In addition‚ evaporation measurements are of great importance for irrigation systems design‚ irrigation rotations‚ and development of hydrologic models. In the present research‚ a seasonal regression-autoregressive “S(REG_AR)” model has been developed and used to simulate and estimate monthly evapo-transpiration‚ and hence water requirements for agricultural

the effect of one specific environmental condition on the rate of transpiration in plants. This particular investigation looked at the number of leaves in a plant and how it would affect the rate of transpiration in plants. The aim of this investigation was to find out if the larger the number of leaves a plant had‚ the higher the rate of transpiration would be. The results from this investigation showed increased transpiration in the plants with the greater number of leaves compared to the ones
