Seedling

A plant life cycle shows how a plant grows and develops over time. In order for plants to grow they need water, the right temperate, and to be in the right location. At the beginning, a plant starts as a seed. The seed will sprout into seedlings, tiny immature plants. The seedling then grows into a mature adult plant that reproduces forming more seeds. All seeds contain embryos, new plants. Some seeds have an outer layer called a seed coat. The seed coat protects and nourishes the embryo. Germination is the next stage of the plant cycle. When seed sprouts forming seedlings and roots come out that is called germination. The sprout uses water and nutrients from the soil as well as sunlight and air to continue to grow. As the roots grow longer the stem will start to push itself towards the light. As the stem grows taller leaves start to appear. The leaves are used to soak in sunlight and carbon dioxide to produce food for the plant. During this process, light is extremely important because plants get their energy from light. As the plant grows the seedlings form into adult…

that can only germinate in really hot weather, such as after a fire has occurred or in the grasslands. Once the seed has made its way to its new location and covered with dirt/water it can begin the germination process. Germination begins when seeds are provided with water and are kept at the right temperature. As the seeds begin taking in the water the seeds start to expand and the food supplies start to become hydrated. The process of seeds taking in the water is called imbibition. In order…

containing 1mM of phosphate (NaH2PO4), while in the experimental (low phosphate) group, 42 A. thaliana seeds were inoculated on a 1 μM phosphate agar plate (Biology 108 Lab Manual 2015). There were 6 agar plates (Class groups) within each treatment group. Using sterile technique with a pasteur pipette, 1 seed per agar plate grid-line was inoculated for a total of 7 seeds per treatment. The agar plates were sealed, labeled, and incubated at room temperature for 2 weeks. Then, germination…

germinated if the seed’s outer layer was split and there was a visible seedling. In addition, qualitative observations regarding the germinating seeds and the physical environment were recorded. * A Diagrammatic representation of the setup is available within the appendix. Safety Precautions: Any direct contact with gibberellic acid may cause irritation, especially when exposed to the skin or eyes. As a result, safety goggles and rubber gloves must be worn when handling solutions containing…

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 of the seed. Once these important parts of the cell are revived they need energy in order to function so the metabolism of the seed becomes active, allowing all of the parts of the seed to complete their necessary functions,…

Impact of Salt on Seed Germination Introduction Germination is a key event in a plant’s lifetime and controlled by two main factors which are water and salt stress (Yuan et al., 2016 and Vallejo et al., 2010). Salt stress affects plant growth and crop production by causing osmotic and ionic stress in plants. Alonso-Blanco et al in 2009 reported that less study was made on the traits in Arabidopsis thaliana despite the immense genetic variation present in the species and the importance of seed…

In both data sets the control group had the highest germination percentage with an average of 24 out of 25 seeds germinated. The relationship of the number of seeds germinated and amount of motor oil is indirect, as the amount of motor oil increases the number of seeds germinated decreases. These findings are similar to other researchers’ works like B.U. Olayinka and O.O. Arinde’s work on Effects of Spent Engine Oil on Germination and Seedling Growth of Groundnut (Arachis hypogaea L.). Their…

Germination is the transition from mature embryos to an actual plant containing both a root and a shoot. This involves having a visible root and shoot as well as cotyledon elongation. (Attree 1990) Once the seed germinates, both a root and a shoot forms, and the seed capsule is pushed up, out of the dirt by the stem before it falls off. The different treatments used in this study affected the overall germination of the Picea mariana seeds. The seeds which were only treated with distilled water…

Introduction/Purpose There are many parts to a seed. First, there is the testa (seed coat). It is the outside layer protecting the inside of the seed. On the side of the seed, there is a tiny hole called the micropyle. Water can be taken through the hole when it is ready to germinate. Inside the seed near the micropyle, there is a root called a radicle. When the seed begins to grow the radicle will come out the micropyle. The seed coat can protect the seed from many factors such as…
