Planaria Regeneration and Development Lab 5 Name: Dominic Siaw TA: Marian Wahl Date Performed: 3/31/15 Date Submitted: 4/14/15 Abstract The purposes of this experiment are to become familiar with the anatomy and behavior of Planaria and make a design to test which aspect of diffusion gradient model which will cause development. The body parts of planaria was observed under a microscope. The flatworms were cut into 3 parts equally based on the gradient…
For this assignment I interviewed Todd Metevia the Head grower at Timbuk Farms in Granville, Ohio. Timbuk Farms is a retail and wholesale grower and distributor. The crop I decided to question about was Coleus. They produce plugs of Coleus that are then sold wholesale to other nurseries. Coleus (Plectranthus scutellarioides) is a commonly grown ornamental plant due to its attractive foliage. Coleus is native to subtropical and tropical areas of Asia and Australia. Although not grown for flowers…
The purpose of this lab activity was to observe the effects that salt has on seed germination, plant growth, and flower production. Similar to humans, plants have vital needs that must be fulfilled in order to grow. Light, water, air, nutrients, and proper temperature all affect plant growth. The importance of these necessities differs widely among plants but are vital nonetheless. Plant health also relies heavily on what scientists refer to as the limiting factor. This concept correlates the…
not lose too much of your respect and promise that this will not happen again. What does it take for something to grow? The main answers are things like water, air, and nutrients; but, the main thing that sparks the chemical reactions within every seed is light. A little light can go a long way, not only in plants but in people. The Greek Enlightenment is something that has never been seen before where... “In that black and fierce world a little centre of white-hot spiritual energy was at…
The original hypothesis, “If ascorbic acid has positive effects on radish seed germination, then radish seeds germinated with ascorbic acid concentrations of 0, 100, 300, and 500 parts per million (ppm) solutions will exhibit longer seed radicles (measured in millimeters) than control seeds germinated in distilled water alone” was incompletely supported. For example, Graph 1 shows the Control trial achieved the greatest average length (31.5 mm) by the end of the experiment in comparison to all…
(More than ten mung beans seeds can be placed in each pot to act as backup in case some of the beans do not germinate. Remove any unwanted plants once germination has occurred). Step two, Use the marker to label the ten pots as “once” or “twice”, followed by one of the following…
the growth of plants? If seeds are exposed to microwave radiation then the growth process will increase. Get three seeds of the same type of vegetable (cucumbers were used in this experiment). Before planting, microwave plant cell #2 for 15 seconds and plant cell #3 for 30 seconds (plant cell #1 is not microwaved at all). After planting them, see the difference in the growth of these seeds over 35 days. The independent variable was the amount of microwave radiation seeds receive. The dependent…
height of a corn seed. To begin, obtain two small planters, each with six individual compartments. Label one planter A and the other B. On the outside of the two small planters label five of the six compartments IAA, NAA, GA, ABA, and Control. The sixth compartment will not be used. These labels respectively correspond to the hormone treatment that each seed will receive. In both planters, fill the five compartments halfway with regular soil. Obtain ten corn seeds and place one seed in the…
Germination is the process in which a plant stems from a seed, and it is fundamental in the development of plants. There are factors that go into how a seed will germinate, one of the most important being temperature. It is said that temperature is an environmental factor that affects germination. Temperature can affect the percent and rate of germination in at least three different ways. The first being that since seeds deteriorate, unless germinated, and the rate of deterioration depends…
Germination is the process by which a plant grows out from a seed. The most common example is the sprouting from a seed of an angiosperm, a flowering plant, or a gymnosperm that are seed-bearing plants. For a seed to germinate, few external conditions are in need to be met as well as internal conditions of the seed such as its dormancy, viability and its vitality to sprout. When these internal conditions are met, the external conditions at the time of seed germination plays a big role. First of…
