growth of a plant? Background Information: When recalling knowledge about what plants need to grow, some things were obvious; sunlight, water, and carbon dioxide. Lima beans are a annual, and need to be in a warm climate to grow best. Lima beans grow best in temperatures between 60 degrees and 70 degrees and prefer a soil pH of 6.0 to 6.8. Also, lima beans need specific water levels to be successful. If you water the plant too much, then the seed can become too saturated and drown. If a plant…

are not limiting, then shoot biomass allocation will increase to compete for light with neighbouring plants. High nutrient and water retention potential associated with increased clay percentages within topsoil can increase shoot productivity, as the presence of readily available nutrients and water allows B. napus to focus energy into growth above-ground rather than below. In the end, overall plant volume and total biomass were marginally affected by soil texture and significantly affected by…

Usually plants grow in natural sunlight, but do they grow the same in colored light? People always just put their plants outside, then leave them. Is there an effect on plants in the colored light, or is it just the same. Part of the plant is the chlorophyll, which is the part of that is responsible for the pigment or color found in the organism. It is responsible for the green color of plants, except in the fall where the pigment changes to red, yellow, or orange. This happens because the…

the water is 38 degrees c, then the growth of the plant will increase. This science fair project is to test whether or not the temperature of the water you water the plant with will affect the growth of the plant. This project is interesting because the way plants grow is an interesting study. In this project i hope to achieve an answer on whether or not a plant’s temperature of water should be a certain temperature to help the growth of the plant. The radish (Raphanus raphanistrum subsp.…

significant positive relationship between the height of the milkweed plant and its number of seedpods. This contradicts the trade-off hypothesis between plant height and the number of seeds produced. The milkweeds may be devoting more resources towards growth earlier in the growing season, and later devoting more resources towards reproduction, which would imply that there is indeed a certain resource allocation strategy that the plants are using, although it is not evident as a negative…

about how plants cannot survive in total darkness and how darkness &light affect the growth of a plant in different ways. Plants cannot survive in total darkness as they use the suns energy and through a process convert it into food, this process is called photosynthesis. The plants that need sunlight to survive, which are majority of plants are called autotrophs. The presence/absence of light and dark play an important role in a plants as they trigger metabolism, growth and behaviour in a…

salinity on pant life more closely, with series of plants watered with different percentages of salt water. To determine how different salinity levels effect the plants growth, and also observe the other effects, if any, that may occur to the plant. The experiment was set up and each plant was watered with different levels of salinity, and measurements of the height and number of leaves was taken twice a week. The results concluded that the plant watered with the tap water had the best…

Plant Growth Lab The world is full of variety of species that help make the Earth a unique place to live in. Many of the species that live on Earth are plants. Plants can be Bryophytes or Tracheophytes. Bryophytes are non vascular and lack roots, stems and leaves. Tracheophytes can be spore producing or seed producing. Seed producing Tracheophytes can be Gymnosperms or Angiosperms. Gymnosperms have seeds that are enclosed in a cone and would include Pines and Coniferous trees. Angiosperms…

Animals and plants react in similar manners when they are faced with their own demise. When we think of communication we often neglect to include plants. Plants have a complex communication system however, it may differ from what you thought. Plants secrete chemicals that serve as their cry for help when being pursued by animals. These alarms attract both large predatory insects such as dragon flies, and tiny parasitic insects, which can destroy the caterpillar from within. Plants have many…

family, and she had wanted to know the reason why these results had occurred. However, in order to properly investigate the problem, one must understand lentil seeds thoroughly. Lentil seeds are a type of legume, which is an agriculturally-grown plant, fruit, or seed in…
