Seed dormancy

and other cell wall materials. Amino acids are used as enzymes and structural components. The net loss of mass of the seed occurs due to change of sugars to CO2 and water where CO2 is lost as gas then O2 taken up by aerobic respiration. Growth occurs by cell division within the embryo and amounts of proteins, cellulose, nucleic acids steadily increase in the growing region of the seed. The first visible sign of growth is the radicle that emerges from the micropyle and is positively geotropic in…

tampered with. The bean seeds that attempted to germinate in the conditions which were different from what they normal would (i.e. colder climate, more acidic water), had to adapt to the new environment and simply couldn’t do so quick enough…

are sepals, petals, stamens, and carpel. Sepals protect the floral bud. Petals help attract pollinators. Stamens bear anthers in which haploid microspores develop into pollen grains containing male gametophytes. Carpel contains ovules (immature seeds) in their swollen bases. Within the ovules, embryos sacs (female’s gametophytes) develop from megaspore. Pollination which precedes fertilization is the placing of pollen on the stigma of a carpel. After pollination, the pollen tube discharges…

acacia decurrens seeds. If the seeds are heated under two different temperatures and soaked in water then the seeds heated under the higher temperature will show greater and faster germination compared to the seeds treated under the lower temperature. Both sets of heated seeds will show greater and faster germination compared to the seeds that were soaked but not heated (control). Method…

PURPOSE To determine how germination and temperature of environment effect respiration rate of seeds. BACKGROUND INFORMATION Cellular Respiration: Is the controlled release of energy from organic compounds in cells to form ATP. Sugar + Oxygen → Carbon dioxide + Water + Energy (ATP). In eukaryotic organisms, respiration occurs to maximize ATP production; this is contrary to anaerobic respiration, which occurs during the absence of a ready supply of oxygen (mostly in prokaryotic organisms).…

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…

include those that cause disease of crops and also those that control noxious weeds. Amy discusses in one of her articles how invasive non-native plants were brought to the Unites States. When different varieties of plants and flowers were sent here the seeds of noxious weeds were accidentally mixed with the plants that were purposely being…

Plants can be the only thing that can stop humans from being endangered or extinct. The reason many people have made that decision is because without Plants there would not probably be any humans alive because of the lack of oxygen. Plants produce oxygen and other materials that humans use by using energy from the sun. Most people need to care about our environment and our treatings with plants and other producers because it can harm our species and it would mostly harm more endangered wildlife…

Plant Science - Seed germination and growth The research question: What is the effect of changing the pH of the soil on the germination and growth of mustard peas? Hypothesis: The greatest number of peas will germinate and will grow the most when the pH is 5 or 7. Theory: Enzymes play a vital role in the cells of plants (especially when growing) and enzymes work best when at their optimum pH value. Moreover, all chemical reactions have an optimum pH at which they work best (Howard and…

The orthologs of candidate genes in QTL regions and their annotation in Arabidopsis were obtained from the result of BLASTn based on gene sequence. Some genes related to seed weight from papers and some searched from Arabidopsis database (https://www.arabidopsis.org/index.jsp) using key words “seed weight”, “seed size”, “cell number” and “endosperm growth”. Homologues were clustered and analyzed using the Database for Annotation Visualization and Integrated Discovery (DAVID) tool, an online…
