The Effect Of Salt Concentration On Plant Growth

If saltwater is applied to a plant, the plant would shrivel up and die. This is a result of the water moving out of the cells in order to try to balance the concentration of solute compared to inside the cell. The water movement out of the cell would cause the cell to shrink and the lack of water would eventually cause the plant to die.

7) What would happen if you applied saltwater to a plant? The saltwater has a lower water potential due to the solute, and therefore water would move out of the plant, dehydrating it.

The purpose of this experiment is to observe the effects of Sodium Chloride (NaCl) on the germination rate of Wisconsin Fast Plants.

Saline environments tend to hinder agricultural production by lowering crop yields, often quite substantially. The traditional response to the threat of salinity-induced crop yield reductions is to apply water in excess of plant requirements so as to leach the salts out of the root zone. (Letey and Dinar, 1986).

Plants are found everywhere on earth, up high on the ridge and down low in caves and caverns. The types of plants that live in these places depends on many factors. These factors are separated into two different categories, the biotic factors and the abiotic factors. Some of the biotic factors include, predation, competition, and habitat destruction. Plants with limited competition and large amounts of resources will be in a higher abundance than plants with limited resources and higher competition rates will be confined to areas and either out competed or will be the dominant species. Certain plants adapt to these factors and thrive and others don’t do as well. Some of the abiotic factors include, sunlight, water, temperature, and wind. These

2. What do you think would happen if you watered your houseplants with salt water?

Plants and animals are very important to human life. Plants and animals developed natural forms

In the novel, The Botany of Desire, Michael Pollan tells the intriguing story of how plants are domesticated from the perspective of the plant with regards to four specific plants.. The four plants he chose for discussion are the apple, the tulip, marijuana, and the potato. As he discusses the domestication of these plants, his overall focus is the desire that each of these plants have to us as humans. Pollan has written books and magazine articles among other pieces of literature that discuss the relationship between plants and humans. Throughout this informational text, Pollan tries to keep the perspective from the “plant’s-eye view of the world,” but he often slips into Pollan’s eye view of the world. As he talks about experiences that he has had with each of these plants and gives a little bit of their history, it was often hard to stay focused on the topic that he was trying to convey. However, I found that the perspectives that Pollan brings up are interesting to think about. The Botany of Desire was an interesting journal type informational novel that didn’t quite live up to my expectations of what it could have been.

There could have been several variables that could have affected the results of this lab. One would have been if the salt measurements were incorrect. If more or less salt was added than realized, this would have caused the results to be incorrect. Another variable could have been the size of the potatoes being measured incorrectly. If

My hypothesis is incorrect because I thought that the salt water would make the plant grow taller than the plant that had tap water, but that actually wasn’t true, the plant that had tap water grew taller than the plant that had salt water. In this project I measured the difference from which plant grows taller using salt water and tap water. The tap water grew the plant the tallest, in trial one it’s growth five, in trial two it’s growth was four, and trial three its growth was six. The salt water grew the plant the shortest, in all of the trials the plants growth was zero.

The plants that grow in saline soils have diverse ionic compositions and a range in concentrations of dissolved salts (Volkmar et al., 1998). These concentrations fluctuate because of changes in water source, drainage, evapo-transpiration, and solute availability (Volkmar et al., 1998). Due to these varying conditions, plant growth depends on a supply of inorganic nutrients, and this level of nutrients varies in time and space (Maathius and Amtmann, 1999). Either extreme condition concerning nutrients results in deficiency or toxicity in plants, and this is demonstrated by salt tolerance (Maathius and Amtmann, 1999). These conditions vary according to the plant species and growth conditions. Little is known about the genetic basis for diversity of salt tolerance in plants, and this could be partly explained through the definitions given for salinity.

     Plants are autotrophs that mean they are able to synthesize food directly from inorganic compounds, instead of relying on other organisms. They use carbon dioxide gas and water to produce sugars and oxygen

Humans depend on plants in numerous ways. One reason we depend on plants is for consumption. Plants have the unique ability of producing their own food through a process called photosynthesis. In this process, plants are able to produce macromolecules such as carbohydrates that cannot be produced in animals or humans. In humans, the only to gain these macromolecules is to consume plant matter, or consume plant-eating animals (herbivores).
