1st base coach and 3rd base coach get out on the field. We were are having a late practice tonight we have to turn the lights on I was talking about my late practice with my mom said that the lights at the field are like the Chloroplast of the cell because the chloroplast uses sunlight to convert energy to make sugar for the cell like the lights uses the light so the player can see what they are doing if it is raining or is dark on the…
This could also lead to evolution, survival of the fittest, overpopulation and the extinction of others. Limiting factors can be many things like space, food, light and many other things. For Sunflowers and example that would lead to carrying capacity would be if all the organisms that consumed or killed the plant would be removed from its environment by an invasive species or environmental changes, then the Sunflowers would grow faster and closer to each other. This would cause space, water,…
Photosynthesis takes in sunlight, carbon dioxide, and water to produce oxygen and glucose through light reactions and the Calvin cycle. This process starts in the chloroplasts of the plant cells. The chlorophyll in the chloroplasts absorb solar energy and converts this to ATP and NADPH. This is achieved when the light energy drives electrons from water to NADP+ to create the NADPH. When the water molecule is split, oxygen is produced as a by-product…
evolution and ecological changes throughout Earth’s history. During the Proterozoic and Archaean eras, the oxygen that all life forms depend on today was produced by numerous cyanobacteria. Cyanobacteria contributed to the origin of plants, the chloroplast present in plants is a symbiotic cyanobacterium living within the plant’s cell. Cyanobacteria are heterocysts that are capable of nitrogen fixation; they convert atmospheric nitrogen into a usable form for plants such as nitrate or ammonia.…
In a cell there are many organelles to help keep the cell functioning. In the cell you could have a cell wall, cell membrane, ribosomes, cytoplasm, flagella, cilia, nucleus, nuclear membrane, nucleolus, chloroplast, Golgi apparatus, lysosomes, mitochondria, plastid, rough endoplasmic reticulum, smooth endoplasmic reticulum, vacuole, and a vesicle. Everyday items can represent many of the organelles. One example of this is by looking at a house. In a house you have a fence. The fence in your…
We have been learning about cells for a long time in science class, and now is the time to put all the hard work and studying to the test. Have you noticed how much a house and a cell are so much alike? If your answer was no then you're about to ‘cause this is: House Theory to Cell Theory Written by E.B. Powers I sat in my room thinking to myself about the cells that we have been learning about in school. While I was thinking, I got really hungry, so I went to my kitchen. As I was making my…
light cycle in which the plant converts light energy into chemical energy and secondly, the Calvin cycle which uses that chemical energy to make sugars for food. To perform these processes, plants use organelles called chloroplasts that absorbs light to fuel the plant. These chloroplasts are consisted of different pigments that absorb specific wavelengths of light, with the two most abundant being chlorophyll a and chlorophyll b. This lab consists of two different experiments that relate to the…
How is light energy harvested in photosynthesis? - The process where plants use light energy and convert it into chemical energy is called photosynthesis. Plants have parts of them like the chlorophyll that is present inside the chloroplast that soak in light starting a process that will end up making ATP. Carbohydrates within the plants are synthesized from carbon dioxide and water. When photosynthesis occurs then sunlight is turned into sugar and this sugar is kept in the molecular bonds of…
photosynthesis and respiration. Introduction Photosynthesis is the most important process on earth. It provides the energy for photoautotrophs to make their food for heterotrophs and is an anabolic process (Reece et al, 2015). Photosynthesis occurs in the chloroplasts. Photons hit the chlorophyll molecules surrounding the Photosystem II complex and excite them. Two electrons and transported into plastoquinone Qb from Phostosystem II and these are replaced…
