dispersal mechanism for plant seeds. Also known as myrmecochory, ants that assist plants in seed dispersal are essential for spreading out the location of future plants of the same species and preventing competition between parent and offspring plants, which would result if an offspring grew too close to a parent plant (Warren et al. 2014). But what causes coevolution between two species? In some cases, where plants are dependent on ants to provide protection, seed dispersal, or to improve conditions

In generalization, there are a multitude of factors that could potentially influence the germination of a radish seed. This lab thoroughly exhibits the effect of water amounts on the germination of a radish seed. There is indeed an in-depth science behind the projected results, and overall of the effects water has on the germination of radish seeds, and the growth of plants in particular. Radishes themselves are moisture-loving plants; therefore, it is significant that they receive an adequate amount

At its heart, Pandora’s Seed, by Spencer Wells, is about the unforeseen consequences resulting from the inexorable march forward in the name of progress originally set in motion thousands of years ago when our Neolithic ancestors decided to grow their own food rather than seeking it out. According to Wells, agriculture is the most important advancement of the last 50,000 years, and the consequences of the shift from hunter-gatherer bands to settlements based around agricultural exploits are more

Radiation Effect the Time it Takes a Radish Seed to Germinate? The independent variable was the microwaved seeds. The dependent variable was the time it takes for the seeds to germinate. Purpose: To observe the effect of electromagnetic radiation on the germination of radish seeds. Background: If you plant a seed, water it, give it sunlight, and good air a plant will grow. Did you know that there is a baby plant inside every seed called an embryo? Seeds are made up of three things, an embryo, the

are many ways to obtain seeds to grow flowers in the springtime, but not all seeds were created equal. Sunflower seeds, for example, can be bought at a garden store in a packet for $1.5 dollars per 6 gram packet, but they can also be found in bird seed for $3.53 dollars per 10 pounds. This experiment intends to find if the germination of a store bought packet of sunflower seeds matches the germination rate of sunflower seeds obtained from a bag of bird seed. While both seeds will germinate, it is believed

Observing the growth hormone acid on germinating seeds. Background: Seed - the germ of a mature plant.Germination - the transition from the seed dormancy in the vegetative growth of the embryo and the formation of a seedling. Basically,germination is a process of growing the plant from the seed. Certain conditions are needed for germinations of the seeds, such as an appropriate amount of water and the right temperature. But for different types os seeds the conditions for growing chances due to their

Evolution in Seed-Eating Finches The purpose of this laboratory simulation is to determine the effects of different factors on the evolution in isolated populations of seed-eating finches. The simulation takes place on hypothetical islands each with a population of finches. The primary finch physical characteristic affected by factors is the bill size which can change from smaller to larger. Larger bills are an advantage with hard seeds while smaller bills are an advantage for eating soft seeds. The islands

PROCEDURE Pre-Lab Procedure: Germinating the Seeds: This procedure must be performed 2-3 days before the laboratory session. 1. Layer moist paper towels in the bottom of a container and sprinkle about 30ml of beans onto the towels. 2. Cover the seeds with more, wet paper towels and then cover the container. Make sure that the towels remain moist for the 2-3 days before the experiment by adding more water every 12 hours. Part One Procedure: 1. Label two paper towels; NG for non-germinating and GM

Germination of Mustard Seeds using Fertilisers 1. Abstract This study was done to look at the effects of fertilisers and identify which fertiliser produced the fastest results. Four types of fertilisers were used over a four-week period and the findings were that inorganic fertilisers enhanced seed germination rates. 2. Introduction Fertilisers are widely used in agricultural production because they contain essential compounds such as phosphorus, nitrogen and potassium that have been depleted

In order for a seed to germinate, many conditions must be met. Firstly a seed must be viable. If a seed is viable it require a suitable environment with proper levels of moisture, suitable temperatures, oxygen, fertile soil, and proper pH levels to name a few. However, as many of us have experienced, some viable (living) seeds will NOT germinate, even when given the perfect conditions. In the field of botany, this phenomenon is known as “physiological seed dormancy” (will be referred to as PSD from
