The Effect Of Nitrogen On The Growth Of A Sapling Essay

Photosynthesis is essential for a plant to survive. In order to perform photosynthesis, carbon dioxide is needed and is the most important component in the creation of matter. There are two other factors that go into photosynthesis, which are solar energy and water. Both are equally important in order to perform photosynthesis, but they don’t create the majority of the matter in a plant. The carbon dioxide is taken from the atmosphere which has a high concentration of carbon. “During the spring when plants start growing again, concentration drops” (Riebeeck p.5). Plants absorb the carbon dioxide and keep it, in order to grow. Once the carbon dioxide is fixated, glucose is produced and used in the process of cellular respiration.

The diagram above shows the two stages of photosynthesis. As you can see, light is a key component as it start the light-dependent reactions which produces ATP and NADPH, which is needed in the light-independent reactions to make glucose. So without light, there is no ATP and NADPH produced and thus no glucose produced, therefore the food chain cannot be started. Glucose is also needed to make DNA and hormones for plant growth, it is also require during plant respiration. So it can be established the light is vital for plant growth and it affects the height of plants indefinitely.

The green pigment involved in photosynthesis is chlorophyll. Chlorophyll is green in appearance because it absorbs red and blue light, making these colours unable to be seen. It is the reflection of the green light that reaches out eyes, giving chlorophyll a green colour. This green light that can be seen cannot be used by the plant for photosynthesis. Therefore, theoretically growth should be inhibited in the plants only exposed to green light.

Photosynthesis is the conversion of light energy to chemical energy into sugars. It is the process in plants that uses carbon dioxide, water, and sunlight from its surroundings and releases oxygen as a byproduct (6H2O+6CO2+light energy -> C6H12O6+6O2). Photosynthesis is required for plants because they are autotrophs, organisms that make their own food. Plants require a specific environment that is ideal to them to be able to carry out the process. Environmental conditions can either increase or decrease the rate of photosynthesis. Things like colors of light, pH, and temperature can all affect the rate of photosynthesis in plants.

Effect of inorganic carbon availability, using varying concentrations of bicarbonate treatments, on the photosynthetic activity of Egeria densa

An important part of photosynthesis is the intake of carbon; thus, it can be presumed that increasing the amount of available carbon will increase photosynthetic activity. In most plants there is an increased rate of photosynthetic rate, but it is limited by other factors and reaches a plateau (Lei H, Zhishan Z.

Nutrients that are obtained from the soil from plant roots are nitrogen, Phosphorus, Potassium, Sulfur, Magnesium, Calcium, Iron, Boron, Manganese, Zinc, Molybdenum, Copper. These twelve elements that are obtained from the soil are called mineral nutrients which are then split into more groups; primary, intermediate and micronutrients (Essential Nutrients, n.d.). Primary nutrients are called by its name because they needed and are found in the most amounts. Primary nutrients include nitrogen, phosphorous and potassium. The intermediate nutrients are sulfur, magnesium and calcium which are found less in soil than primary nutrients. Primary and secondary nutrients are called macronutrients. Iron, boron, manganese, zinc, molybdenum and copper are called micronutrients because they are needed in very small amounts. So small in fact that they are needed in parts per million, where 10000 parts per million is 1% of the plants intake (Essential Nutrients, n.d.). This doesn’t mean that the plant won’t grow as well without it though, these nutrients can still be essential to maximum growth spurt (Essential Nutrients,

Eutrophication, a term that derives from two greek words, eu, meaning “good,” and trophic, meaning nutrition or nourishment, is the enrichment of water bodies with nutrients like nitrogen and phosphorous that stimulate plant growth. Nitrogen is often found in rocks, soils, organisms, and the atmosphere; phosphorous resides mostly in rocks/soils and organisms. Having nitrogen and phosphorus in the ecosystem isn 't necessarily a bad thing, in fact, it 's required. Nitrogen is needed for the production of proteins and amnio acids, while phosphorous is required for the synthesis of DNA and RNA, and is involved in energy transfers. (Danver & Burch, 2011) However, too much of a good thing, can be a bad thing.

In this lab, four different types of leaves were tested to see the rate at which each leaf photosynthesized. This lab demonstrates how plants store light, capture light, and use light as energy for reproduction and growth, by photosynthesis. The control in this experiment was spinach, which was tested before any of the other plants were. The other plants that were tested were English Ivy, C4 Plant, and a multicolored plant. Each type of leaf was tested in a sodium bicarbonate solution and a solution of distilled water. It will be shown in the discussion whether the hypothesis made was correct or incorrect. It will be shown in the discussion what could have

What is the relationship between the increase in light intensity and the photosynthetic rate in leaves from a corn plant? How does this relationship compare with what you observed for tomato plants?

Photosynthesis is an essential importance to organisms. It is the process by which green plants and a few organisms convert sunlight energy into chemical energy which is stored in molecules. Photosynthesis in green plants generally involves the

Plant growth is dependent on environment factors and the activities of the meristematic tissues after germination (Dunlop et al, 2010). Some environmental factors that will affect plant growth are soil pH and external stimulus. Most plants can only grow well within a narrow range of pH values; 6-8 (Dunlop et al, 2010). Any soil that is more acidic or basic will result in poor or no plant growth. Phototropism is the growth response of a plant to light due to an unequal distribution of auxin (Dunlop et al, 2010; Tucker, 2006). This causes the plant to grow towards the light source and the cells on the side opposite to the light elongate. Dunlop & Tucker state that this results in the stem curving towards the direction of the light.The meristematic

Pea plants, along with many other plants and vegetables, are taken for granted. Without them, much of the world would be

Plant foods contain three essential nutrients that are not readily available from soils. These are soluble compounds of nitrogen, phosphorus, and potassium. A typical label on a plant food will have a set of numbers such as 15-30-15. These numbers mean that the plant food is guaranteed to contain at least 15% nitrogen, 30% phosphorus (expressed as P2O5) and

All this lights have equally conurbation towards plants growth but without any light then there is no process of photosynthesis which means there no plant growth at all. Photosynthesis is the procedure whereby radian vitality from the sun is changed over to the concoction bond vitality of glucose. In plants it happens in chloroplasts which concentrated cells. Chlorophyll atoms are instrumental in the first step, which is the change of light vitality to the substance bond vitality of ATP. Vitality to change carbon dioxide and hydrogen to glucose is then given by the ATP. Oxygen is discharged as a waste result of procedure. The reaction is shown below:
