Influence of Acidic Solutions on Lettuce Seed Germination Introduction In the environment‚ plants are critically affected by the composition of soil‚ as they acquire all nutrients from it. A nutrient must be soluble and must remain soluble long enough in order to travel into the roots of the plant (Kissel and Miller‚ 2008). Soil PH directly affects the life and growth of a plant‚ since it affects the availability of the nutrients needed for plant life. Most nutrients are in their most available

BIOLOGY GERMINATION EXPERIMENT INTRODUCTION: Germination is the resumption of growth of the embryo plant inside the seed. Requirements for germination: * proper temperature * the presence of adequate water * oxygen There are two types of cotyledons: the monocotyledons (“monocots”) and the dicotyledons (“dicots”). Monocots have one cotyledon. Rice and corn are monocots. Dicots have two cotyledons. Lentils‚ lima beans‚ and green beans are dicots.* Germination in Dicots 1

Justification Paper Jim Lammers There is no disputing the fact that performance enhancing drugs have the potential to raise the level of competition in athletics. The goals in sport can be boiled down to higher‚ farther‚ and faster; therefore in order to improve competition it is necessary to make athletes bigger‚ faster and stronger. Professional athletes (not collegiate or interscholastic) should be allowed to make choices in their training regimen which will make them better prepared to do the

IRP 3: Germination Introduction: Germination is the process of which a plant of fungus emerges from its seed or spore. Germination involves activating the seed’s metabolism‚ which is done through numerous stages. The fist stage involves the rehydrating the cell by absorbing water. This allows the cell to become metabolically active. After water absorption‚ gibberellin is produced in the cotyledon of the seed. The enzyme gibberellin stimulates the production of amylase‚ which catalyzes the

It was evident since the start of the lap that the big question was‚ how does temperature affect radish germination. The original hypothesis was if temperature affects the tail length of the germinated seed‚ then a higher temperature will lead to a significant decrease in the tail length of the germinated seed. This hypothesis is true‚ according to the collected data. After 6 days of letting the seeds germinate‚ the ones that germinated in room temperature were quicker to germinate and with a lot

tests the process of germination with various pH levels. The pH level of something is its measure of acidity or how basic it is‚ solutions with a pH of less than 7 are said to be acidic‚ and solutions with a pH greater than 7 are said to be basic. The tap water that was used to water our beans had a pH of 6. In this lab‚ we studied the process of germination (the process by which a plant grows from a seed). Certain environmental factors can cause or stop a seed’s germination‚ and these factors include

Seed Germination‚ Dormancy‚ and Storage 1 _________________ I. INTRODUCTION Seeds role in the germination process is a critical part in the plant ’s survival. This is practically true in almost all of the plants species (Copeland & McDonald‚ 1995). As germination is defined as "the emergence and development from the seed embryo of those essential structure"‚ which‚ for the kind of seed in question indicates "its ability to produce a normal plant under favorable

In this lab the rate of germination in relation to temperature was observed testing the hypothesis‚ if the seeds are exposed to cold temperatures then they will not germinate. In the standard germination test a total of one hundred corn seeds were divided into four groups of twenty-five and each group was used to make a ragdoll. The rag dolls were germinated in room temperature. In the cold test one hundred corn seeds were placed on four layers of moist paper towels in the bottom of a metal tray

Received: 15th February 2012 Abstract: Pollen obtained from the Hibiscus rosa-sinensis‚ commonly known as the Hibiscus flower were exposed to different concentrations of Lead to understand the effect of heavy metal on pollen tube germination. Heavy metals such as Lead‚ have shown to decrease the pollen germination and inhibit pollen tube growth. There was a correlation observed between the concentration
