Essay On Plant Growth

787 Words4 Pages

Did you know that there are 391,000 plant species in the world, but have you ever thought how many of those plants grow in different color light? Well I have! The purpose of this paper is to explain why and how plants react to different colors of light. In this paper I will be talking about how plant growth works, why morphology is important to plant growth, and how different wavelengths of light affect plant growth. Now, let's grow ourselves into the next paragraph.
Have you ever wondered how plant growth works? Well I'm here to explain it to you. Have you ever noticed how a fresh seed that is still green cannot bear life? A fully developed seed has a protective cover over it called a testa. Once this seed falls to the ground and gets enough water and the temperature is right it starts to germinate. This is the dormant stage.
The next stage is the Germination stage. In this stage the water that was absorbed nourishes the seeds embryo which then helps the process of cell duplication. This then causes the seed to expand causing the embryonic plant to sprout. Embryonic plant means a plant in its earliest stage of development. The next stage is the growth stage. In this stage plants have …show more content…

Ultraviolet light can harm plants if they are overexposed. Especially to the shortest of ultraviolet wavelengths. Although the Earth’s atmosphere filters out most of the most harmful ultraviolet wavelengths, deterioration of the ozone layer has plant scientists worried about Earth’s vegetation in the future. The ozone layer of the earth is a layer in the earth's stratosphere containing a high concentration of ozone, which absorbs most of the ultraviolet radiation reaching the earth from the sun. Ozone Is a unstable toxic gas with a pungent odor and powerful oxidizing properties, formed from oxygen by ultraviolet light. So now that we have learned about what light does to plants lets sprout

  • Summary Of Growing By Viramontes

    1139 Words  | 5 Pages

    In her collection of short stories, Moths and Other Short Stories, Helena Maria Viramontes elaborates on the importance machismo has on struggles of Chicano women in their daily lives. In the short story, “Growing”, Naomi is faced with the struggle of growing up in a “machista” household where transitioning to womanhood means to forgo any trace of childhood. In another short story, “Birthday”, Alice is faced with the struggle of an unwanted pregnancy and a decision to terminate the pregnancy. Through the use of plot and diction, both of Viramontes’s short stories “Growing” and “Birthday” illustrate the influence machismo has on the norms and gender roles of women to grow up and bear children, in order to emphasize the characters breaking through

Eiseley described it as “exploding upon the world with truly revolutionary violence”.

  • Germinated Seeds In The Dark Essay

    387 Words  | 2 Pages

    We accept our hypothesis of the germinated seeds in the dark and the dormant seeds in the dark having a higher rate of cellular respiration then germinated seeds in the light and the dormant seeds in the light. The germinated seeds in the dark had 0mL of change in oxygen levels while the germinated seeds in the light had -.05mL of change in their oxygen levels. The germinated seeds in the dark had a .05mL more for their change in oxygen then the germinated seeds in the light, therefore the germinated seeds in the dark had a higher rate of cellular respiration then the germinated seeds in the light. The dormant seeds in the dark had 0mL of change in their oxygen levels and the dormant seeds in the light had -.16mL of change in their oxygen levels. The dormant seeds in the dark had a .16mL greater change in their

  • Germinated Peas Inspire Synthesis

    412 Words  | 2 Pages

    The purpose of this lab was to measure the amount of CO2 gas given off by germinated peas under certain conditions of light. We conjectured that the more amount of light the peas are exposed to, the higher the respiration rate they will have. Our data supported this because it showed that the germinated peas that were exposed to light 24 hours before the experiment had a steeper slope (as seen in table 1), therefore having a greater respiration rate. The peas that were not exposed to any light 24 hours before the experiment had a reduced rate because of its lack of exposure to light. Both pea’s respiration rates showed that the more light the peas were exposed to, the greater respiration rate they would have (Figure 1).
