Who’s the better reproducer? With time comes change and with change comes evolution. Organisms are classified into three distinctive groupings: Bacteria, Archea, and Eukarya and the kingdom of plants (Plantae) falls under Eukarya. It could be argued that plants are one of the most valued organisms on Earth. Not only do they provide oxygen for the oxygen dependant organisms, such as mammals through the process of photosynthesis, but, they also provide stable conditions and habitats for other…

Introduction As it is true with humans and most living organisms, plants grow throughout their life cycles. Plants undergo both primary and secondary growth, those being vertically and in girth, respectively. However, plant growth differs from human growth in that plant growth is the result of external factors such as optimal soil conditions, sunlight, water, as well as internal factors such as hormones. Hormones can be defined as molecular signals, which are produced in small amounts by one…

received various plants from distributor and my group was assigned Celosia, Dust silver, and Petunia plugs. We planted the plugs plants into various pots, six inch pots, four inch and six cell packs were used during this report. In preparation of planting Miracle Gro potting mix was used as the media, we dumped the media into out of the bag unto the table, mixed the media with water in making it moist for better growth. The next step was to fill in the four-inch, six-inch and six Cell Park with…

Believe it or not, some plants can feel just like us, but even better, thanks to thigmotropism. Thigmotropism is a plant’s way of touching, or feeling. Thigmotropism is one of the tropisms, in which plants use to react with their environments. “Scientifically defined, it is the directional response of a plant organ to touch or physical contact with a solid object (1).” When a plant comes into contact with an object of a solid state, the response is to curl around it. “A Morning Glorie’s sense of…

Role of Ethylene in Plants The development of the plants involves the progressive and recessive birth and death of their parts such as shoots, roots, leaves, flowers and buds. The tree shape could be examined by taking into account the numbers of parts that determine the longevity and final outcomes. The outcomes of buds are determined by their location on the tree. While many factors are involve in the regulation of this developmental pattern. Ethylene plays an important role in the…

are made up by the building blocks of life named “cells”. They are the foundation of life and contain microscopic components called organelles which carry out complex tasks to provide the “basic structural, functional, and biological unit of all known living organisms” (Wikipedia, Cell(Biology), viewed 19th March 2016, Cells can be classified into two major groups- Prokaryotic and Eukaryotic cells. Prokaryotes are organisms that do not contain a cell nucleus and have no membrane bound…

about a total of 13 weeks for the Brassica Rapa Plants to complete their full life cycle (Figure 4). To begin, F1 Wisconsin Brassica Rapa fast plant hybrid generation seeds made from a cross between a homozygous purple pigmented plant and a homozygous green pigmented plant are planted in soil. This process required obtaining a six-celled tray filled with 75% soil. Within that soil contained one MiraceGro All Purpose Plant Food fertilizer. The Fast Plant seeds…

growing into a fully mature plant. When enough water is near the seed it enters the cell by osmosis, specifically a type of osmosis called imbibition when the seeds are in a dormant state. The flow of the water into the seed reinstates a hypotonic environment.This recreates turgor pressure inside the cells causing the cell walls to be rigid, the cells to expand, and the seed to start to grow (J. Bewley, 1997). The presence of water inside the seed rehydrates enzymes, cells, and other structures…

determine the ecological state of the Reddam House wetland, which I presume is at a good standard. I decided to test the ecological status of the wetland by gathering samples from the wetland and testing it for various aspects in the water and the plants that are found within the area. Method: • Collected water in a sterilized bottle at Reddam House wetland as well as observed surrounding fauna and flora. • Took the water to Rand Water to have it tested as well as took photos of the vegetation…

in development and in the plant life cycle. In these plants, the haploid and diploid stages exist independently, making it easier to study them without influencing the cell life cycle. The haploid stage is the gametophyte stage and the diploid is the sporophyte stage. The second exclusive property that these plants possess is the fact that the spores develop into gametophytes and then into young sporophytes in 2-3 weeks, which making it very less time consuming. Plants require many nutrients…
