Botany Essay Questions 1. Pollination is a crucial process of how plants reproduce‚ in which the male sex cell of the flower‚ pollen‚ is transferred from the stamen to the carpel‚ or more specifically‚ from the anther to the stigma. Pollen grains are completely different and unique for each flower‚ they carry the male and female genetic information and it is split exactly 50/50. The transfer is carried out by pollinators‚ which include bees‚ wasps‚ flies‚ butterflies‚ moths‚ several species

Water Treatment Plant Process- Chlorination or Ultraviolet Radiation By Shreya Shah Surface waters necessitate water treatment before consumption to guarantee no health risk is present to the user. Poor quality water which consists of dissolved and suspended particles‚ can impact and cause health risks to consumers. The most important contamination is the microbiological contamination as it leads to infectious diseases (Water Treatment‚ 1994). Chemicals such as nitrates and cyanide when contaminate

“Do Different Music Genres Affect Plant Growth?” The purpose is to test how different music genres affect plant growth. The test may or may not validate the hypothesis made‚ that the plants exposed to classical music will be effected in a more positive way than the plants which are exposed to hardcore music. The procedure is as follows: Nine dyanthus flowers are separated into three groups: classical music‚ control group‚ and hardcore music. Every morning plants are watered and left outside for

we should learn about something new and difficult. A problem this plant faces is‚ it’s one of the world’s most endangered plant. It was found because it was a juvenile plant and it has been non-existent and last seen since 2003. The Cyanea Kuhihewa died because of a hurricane in Hawaii that impacted Kauai. Scientist are trying to create a genetic version of the plant but it will be a very hard process. The botanic garden grows plants that are all offspring of the same parent. In my opinion‚ you can’t

Seeds require moisture to germinate. By presoaking a seed‚ it strips of the protective layer of the seed and speeds up the rate of germination. But the longer someone presoaks a seed‚ the greater the chance it has to rot. When presoaking seeds‚ one should avoid planting them in dry ground due to the risk of the moisture being taken out of the seeds instead of sticking with it to germinate‚ leaving the seed back to its original state. purpose - There are many factors that affect germination‚ however
