Plant hormones are specialized chemical substances produced by plants. They are the main internal factors controlling growth and development. Hormones are produced in one part of a plant and transported to others‚ where they are effective in very small amounts. Depending on the target tissue‚ a given hormone may have different effects. Plant hormones play an integral role in controlling the growth and development of plants. A plant hormone is generally described as an organic compound synthesized

Plants Organs As was noted in the previous chapter‚ most plant cells are specialized to a greater or lesser degree‚ and arranged together in tissues. A tissue can be simple or complex depending upon whether it is composed of one or more than one type of cell. Tissues are further arranged or combined into organs that carry out life functions of the organism. Plant organs include the leaf‚ stem‚ root‚ and reproductive structures. The first three are sometimes called the vegetative

Does Aspirin Effect Plant Growth Plant Science The question of this science fair project question is “Does Aspirin Effect Plant Growth.” This is a good question because aspirin help human get better but‚ will it help plant grow bigger. Or maybe it makes the plant grow faster? Or maybe it can make the plant not grow at all. In this science experiment I am using dieffenbachia plants. Dieffenbachia plants are usually house plants. This is great because this science experiment is being done in the

organic materials which are used for cellular function (Wikipedia). Plants are an example of this kind of organism. A current scientific topic in regard to photoautotrophs is the topic of non-native invasive plants. When a plant is non-native‚ or exotic‚ it means that it is not originally from the United States. They are often brought to an area by accident‚ possibly for agricultural or horticultural purposes. An invasive plant is one that is established‚ then expand and reproduce on their own

crowding have on bean plants? My prediction was that crowding would have no effect on them. I predicted it this way because plants are made to grow in tough conditions and I dident think crowding would have any effect.

Take your seeds but before you plant them weigh them for

microbe‚ a human‚ or an animal‚ then you are most likely plant. Plants and trees cover about thirty percent of the planet’s surface‚ as stated in NASA’s Earth Observatory division. They use a process called photosynthesis‚ which allows plants to take energy from the Sun and later using it as food‚ as well as producing oxygen through the process of respiration. So how does it happen? The process of photosynthesis occurs as follows. First‚ the plant uses the sunlight and the green color in their leaves

Introduction There are both virulent and non-virulent bacteria and fungi that grow on plants. It is difficult to distinguish between the two without proper inspection and diagnosis of the diseased plant to know whether the bacteria or the fungus in question is the virulent or non-virulent one. Therefore pure cultures need to be isolated to know with absolute certainty which is the causative bacteria or fungus. Potato dextrose agar is a good nutrient agar for mycelia to thrive on which is present

DISCUSSION Bryophytes are seedless plants without specialized water conducting tissues. Bryophytes include mosses (phylumBryophyta)‚ liverworts (phylum Marchantiophyta Hepatophyta)‚ and hornworts (phylum Anthocerophyta). They are plants that virtually everyone has seen‚ but many have ignored. The most commonly encountered group is the green mosses that cover rotting logs‚ anchor to the bark of trees‚ and grow in the spray of waterfalls‚ along streams and in bogs. Even though mosses often thrive in

Experiment 5. Uptake of water by an uprooted plant - preparation Outline A small uprooted plant is sealed into a 5 or 10 cm3 plastic syringe barrel with ’Blu-tack’ or similar material and fitted to a potometer. Prior knowledge The questions assume that the student has an understanding of photosynthesis. Advance preparation and materials Plants. Dig up small plants (e.g. garden weeds) 10-20 cm tall and wash as much soil as possible off their roots. Select those whose root system can

Introduction Man has propagated plant material almost as long as he has cultivated the land to produce food. For a long time‚ plant material was propagated mainly by using the seeds of existing plants. Better methods were discovered over time‚ methods that allowed the farmer to retain the desirable qualities of the plant material‚ while eliminating some of the less desirable qualities. Through these methods‚ the farmer was also able to eliminate the variations between plants of the same cultivar and produce
