Radish Seed Lab Report Problem: What caffeinated drink (monster‚ coffee‚ or green tea) will the radish seeds grow in the best form over a nine day period? Hypothesis: If the radish seeds put in the dish with the drink Monster‚ then the seeds will grow faster because of the amount of energy given to them. The amount of caffeine in Coffee is much greater than the amount in green tea and Monster‚ but neither coffee nor green tea contains any extra type of an energy booster like the Monster does.

In this lab we used radish seeds planted in twelve different pots and three different percentages of isopropyl alcohol (5%‚ 10%‚ & 20%). The first three pots were the controls and they were only given tap water. The second set of three pots were labeled as the low group and they were each given 5% of isopropyl alcohol. The third set of three pots were labeled as the medium group and they were each given 10% of isopropyl alcohol. The fourth set of three pots were labeled as the high group and they

INTRODUCTION A seed is a fertilized ovule that contains an embryo and transforms it into a new plant through the process of germination. Seeds remain inactive until conditions are right for germination. All seeds need water‚ oxygen‚ and proper temperature in order to germinate. However‚ some seeds require full light or darkness to germinate. According to Holm (1996) seeds have chemical inhibitors that prevent germination. A seed will not grow unless those inhibitors are destroyed by things like

Bioassay of Radish Seeds Bioassay is a type of scientific experiment used in the development of new drugs and monitoring pollutants. It estimates the potency of a substance‚ by testing its effect on living matter. In other words‚ it determines how much of the substance is needed to poison an individual‚ without testing it on any humans or animals. From here the TC50 of the substance can be adjusted for dealing with humans and animals over plants. In this lab we attempted to find the potency of

The purpose of this lab was to investigate how size of seeds impact respiration rate. It was hypothesized that bigger seed will require more oxygen because more energy is needed to sustain the seed’s homeostasis. For this experiment 4 groups was set up with 0.5 mL worth of the following seeds: peas (1) ‚ black beans (1)‚ radish seeds‚ and glass beads (control). The black bean served as the biggest size‚ peas were medium‚ and radish seeds were the smallest. After setting up the microrespirometer and

this experiment was the bag that contained the radish seeds with tap water. This was an important part to have in the experimental design because I was able to compare this to the other bags that contained coffee‚ ammonia‚ and vinegar. With the results that I collected‚ I was able to gather more observation and data. 2) The independent variable in this experiment was the pH level of the solutions‚ whereas the dependent variable was number of seeds that each solution was able to germinate. Some

high densities of radish and wheat seeds affect the plants growth rate and competition. The competition occurs when resources are limited to the plants. The two types of competitions that occur are interspecific and intraspecific. Interspecific is a competition between two different species and intraspecific is a competition between the plants own species. This experiment was conducted by taking 6 pots containing soil and placing certain amount of seeds‚ radish or/and wheat seeds‚ in each pot. A

Seed Lab I. Purpose/Question: A. What is the variable you are testing? Radish seed vs. Pea seed B. Question 1: How does seed type affect when the seeds germinate? C. Question 2: How does seed type affect the length of the stem? II. Research: List two pieces of information you learned about the variable you are testing below. The radish stem was longer. Both seeds germinated equally fast. III. Hypothesis: Make these an “If-then” statement and do not use pronouns (I‚ we‚ he‚

Radish and Collard lab Intro Purpose: To see if the population density affect the growth (mass) and germination of individuals of two species growing alone and in mixed species groups. Hypothesis: If planted like treatment 1 (8 collards) and 4 (8 radish) then it will have a higher mass and a greater germination percentage. If the plant is planted with a smaller population density and has intraspecific competition then the radish and collard will have higher germination percentages and mass averages

Introduction This experiment is designed to test the allelopathy of two different treatments‚ Eucalyptus (Eucalyptus cinerea) and Lemon (Citrus limon). The two treatments will be tested on radish seeds (Raphanus sativus) to investigate the effect of the treatments on the germination of the radish seeds. Allelopathy is the beneficial or harmful effects that one plant has on another plant by the release of chemicals. Allelopathy studies the interactions among plants‚ fungi‚ algae and bacteria
