Cotyledon

seeds were treated with 3 different salt concentrations which are 0.1M, 0.2M and 0.3M. Each of the genotypes was placed in 0M salt concentration as well which acts as the control. We used 10 ml of distilled water for the control and mixed 1ml of NaCl with 9 ml of distilled water for 0.1M salt concentration. Next, for 0.2M and 0.3M salt concentration, we mixed 2ml of NaCl with 8 ml of distilled water, and 3ml of NaCl with 7 ml distilled water respectively. Next, we placed a piece of tissue in the Petri dishes and sprinkled the solution in each Petri dish. Then, we divided each Petri dish into 4 compartments and placed 10 seeds of the same genotype in each compartment to set the replicates for each genotype. We observed the number of green cotyledons that came out once the seed germinated and counted them (De-Rose Wilson and Gaut, 2011). The seed germination for each genotype and concentration were recorded every two days for 14 days. For the experiment, we tested the different mean of germination for each seed genotype in different salt concentration using Kruskal-Wallis test implemented in R to calculate the p-value. The raw data was log-transformed as it didn’t satisfy the normality assumption (DeRose-Wilson and Gaut, 2011). Results Based on the observation that we made, it was found that all of the genotypes only have their seed germinated for 0M and 0.1M salt concentration. None of the seed germinated for salt concentration 0.2M and 0.3M. Table 1 shows that the…

The radicle is the first part of a seed that emerges during germination. The radicle becomes the first root of the plant, and uses geotropic forces (with gravity) to grow downwards into the soil. The hypocotyl grows above the stem to support the cotyledons as the radicle begins to grow. The radicle bursts through micropyle on the side of the testa (seed coat) during the first 3-4 days of germination. It pushes its way through soil below using energy from the cotyledons, which is converted to ATP…

to grow. The seed first has its roots break out and grab hold of the soil. After the roots have a hold of the soil a small plant will sprout from the ground. All plants go through the germination process. (How do Seeds Sprout?) The hypothesis is: If the weight of a seed affects the rate the plant grows, then a heavier seed will grow faster. Seeds are made up of only a few components. The outer layer of the seed is called the seed coat. Seed coats protect the seed from anything that can harm it.…

In this experiment, the problem that was being investigated was the effect of Miracle Gro on the germination of lentil seeds over a period of three days. This problem was investigated in the interest of Ms. Semaan and her past experiences with lentils. She and her family had previously grown lentil seeds seasonally and compared them to her relatives’ seeds in terms of growth and height. More often than not, the relatives’ lentils grew better than those of Ms. Semaan and her family, and she had…

angiosperms. Their success results, in part, from two innovative structures: the flower and the fruit. Flowers are derived evolutionarily from modified leaves. The main parts of a flower are the sepals and petals, which protect the reproductive parts: the stamens and the carpels. The stamens produce the male gametes, which are pollen grains. The carpels contain the female gametes, which are the eggs inside ovaries. The walls of the ovary thicken after fertilization, ripening into fruit that can…

which they are acting (Prakash, Upadhyay, Singh, & Singh, 2007;Kim et al., 2006; Shi, Nam, & Ma, 2010). Black mung beans were found to be excellent dietary sources of natural antioxidants for health promotion; meanwhile, these mung bean sources exhibited great potential to be developed into functional foods or nutraceutical ingredients for maintaining glycemic control and alleviating diabetic complications(Yao, Y., Yang, X., Tian, J., Liu, C., Cheng, X., & Ren, G.2013). Peas, more specifically…

The cultivar cocoa, Theobroma cacao L is the family of Sterculiaceae. Cocoa is a dicots, it have two cotyledons, taproot and five floral parts. During seed germination, the initial grow is tap root and followed by hypocotyls up above ground level. It take three month to develop mature tree root. In duration, the stem will develop based on growth the cotyledon. The plumule will appear, its depend on emerge of cotyledon and the first four leaves will follow growth. The lateral branch of cocoa tree…

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…

examples of these micro-organisms are bacteria, fungi and viruses, although visible to the naked eye, the symptoms include wilting, yellowing, stunting and abnormal growth patterns (Encyclopedia, n.d.). There is an 80% chance that plant diseases such as fungi can affect a seed. It grows on dead plant tissue but can penetrate plant tissue or grow on plant surface. The fungal spores, however act like seeds and can be spread by wind, water, soil and animals to other plants, and is able to populate…

soil seed normally begins to germinates then they get an appropriate range of soil,temperature and when water and oxygen are available.During germination the seeds absorb water either through the micropyle(pore like opening) it is present or through the testa(outer seed coat) when it is permeable.The entry of water actives the embryo cells.Ones soaked for the required time,the part of the plant that first emerges from the seed is the embryonic root known as the radicle allows the seedling to…
