PLANT RESPONSES TROPISM is a biological phenomenon‚ indicating growth or turning movement of a biological organism‚ usually a plant‚ in response to an environmental stimulus. In tropisms‚ this response is dependent on the direction of the species. The word tropism comes from the Greek trope ("to turn" or "to change"). Tropisms are usually named for the stimulus involved and may be either positive (towards the stimulus) or negative (away from the stimulus). Phototropism is the growth response

Distance of a Seeds Distribution by Wind Introduction Seeds can be distributed three main ways: wind‚ water and animals. In this experiment‚ wind will be tested due to the fact that wind can be controlled in an indoor environment and can carry seeds farther and longer in the air and bring the seeds to a new area to grow. There are many types of seeds that travel through the air in a unique way. One way seeds can travel is through gliding‚ which is having two lateral wings that look like one of

Respiration of Germinating Peas Abstract Aerobic respiration is an enzyme mediated process during which glucose is used to make ATP to fuel the cells energy needs. Germination is one of such processes that make use of aerobic respiration and because certain factors can affect aerobic respiration‚ it would also affect germination. In this experiment‚ we examined the effects of boiling on the rate of aerobic respiration of germinating peas. Unboiled germinating peas were found to have a more rapid

Effect of seed germination Purpose: To see the effect of an acid introduced during seed germination‚ on the length of the plant roots. Also shows how salt can affect the seed germination. Acid can be introduced to seeds during germination if there is acid rain. Knowing the results of acid rain on seed germination will help us understand how to grow pants better‚ and how to have more successful germination. Salt can be introduced into a seed during germination because salt is put on roads and the

This experiment will test whether or not radiation will help or hurt grass seed growth. This experiment will also test whether or not radiation will help or hurt grass seed germination. If the experiment goes according to plan‚ the most reasonable hypothesis based on the research is that the radiation will negatively affect both the plant growth and

card board box with a hole on one side‚ and water. Procedure of the experiment: Two pots are prepared by filling them with soil‚ and are labelled as A and B. A few (2-3) mustard seeds are sown in each of them. The conditions necessary for germination of seeds such as oxygen‚ moisture (water)‚ and optimum temperature are provided in order to allow them to germinate and grow in both the pots A and B for a period of three days. Thus‚ the amount of moisture (water)‚ availability of oxygen‚ temperature
Premium Seed Experiment Scientific method
Plants have two different ways to reproduce. The first one is vegetative reproduction. With this type all the plants that have the same parent have the same genetic make-up. This also lets plants pass adaptations on that they have abtained over the years. Plants with good genetic make-up usually spread quickly and take over an area. An example of this would be the dandelion. These plants can sprout from any part of the plant. An example of this is the potato‚ farmers will pick the potatoes and cut

Paraserianthes falcataria - Southeast Asia’s Growth Champion By whatever common or scientific names it is known‚ Paraserianthes falcataria (L.) Nielsen is a valuable multipurpose tree for the humid tropics. One of the fastest growing of all tree species‚ it is used for pulp and other wood products‚ fuelwood‚ ornamental plantings and shade for coffee‚ tea and cattle. Potential uses for which it is being tested include alley farming and intercropping in forest plantations. BOTANY: "Falcataria"
