title: (Plant Protection) NAME: Karl Fitzpatrick. Date: 16/12/15. Describe five specific situations where pest and disease control measures are required: Vineweevil: This is an insect that attacks a wide range of plants‚ both indoors and outdoors‚ but can be especially damaging to container plants. He needs to be controlled otherwise he will kill the plant. Adult weevils eat plant leaves during spring and summer‚ its the grubs in autumn winter attack the roots of the plants‚ plants growing

The Affect of Different Colored Light on Plant Growth Puprose: Just as we are happier and healthier when we receive adequate sunlight‚ so are the plants and vegetation that we grow. Sunlight‚ or other means of artificial lighting is essential to help a plant grow into maturity. It is also necessary in aiding the plant to get the nutrients it requires to mature into a strong healthy plant. The process of the sun or other light helping to feed the plant is called photosynthesis. The light acts

Rhetorical Analysis on “The science‚ policy and ethics of stem cell research” Doctors‚ researchers‚ patients and virtually anyone interested in the future of medicine are intrigued by the key role human embryonic stem cell research could have in curing well-known diseases such as cancer. As much as people are curious about how it could advance medicine in incredible ways‚ there remains the issue of whether finding a cure using human embryos is ethically sound. The answer to this question is heavily

-How plants get liquid and minerals- Flowers absorb liquid through their roots‚ which are attached to xylem vessels. Xylem vessels are tubes that can expand through several feet of tissue and be .7mm in diameter. Their walls are thickened with cellulose deposits. Xylem bring water up to the leaves and petals of the plant. Even without contact with the roots‚ the xylem can still absorb water. Because of this‚ a cut flower usually doesn’t die for a couple days (as long as it is placed in water of

Amount of Water Effects Plant Growth By Dennis Marchuk Turner Ashby High School Grade 10 March 23‚ 2013 The purpose of this project was to determine how much the amount of water effected plant growth. This had been accomplished by taking three groups of plants and placing them next to one another. Each group contains two plants. Each one would be watered with a different amount of water. They would then be measured how much they grew. The growth of the three plants was compared. Hypothesis:

Animal and Plant cells consist of most of the same cell types‚ but the whole shape of the cell is quite different. An animal cell is a round‚ uneven shape‚ whereas the Plant cell has an affixed shape. They have a more of a rectangular shape. Chloroplast‚ Vacuole and the Cell wall are only found in Plant cells. The Chloroplast is the organelle for the whole system of Photosynthesis. Chloroplasts are found in mesophyll cells (which are found in the leaves) of green plants. They convert light into

Background and Aims Precocious flowering in apple trees is often associated with a smaller tree size. The hypothesis was tested that floral evocation in axillary buds‚ induced by dwarfing rootstocks‚ reduces the vigour of annual shoots developing from these buds compared with shoots developing from vegetative buds. Methods The experimental system provided a wide range of possible tree vigour using ‘Royal Gala’ scions and M.9 (dwarfing) and MM.106 (non-dwarfing) as rootstocks and interstocks. Second-year
