Each chloroplast has two outer membranes, which encloses a semi-fluid interior called the stroma. I inside the stroma is a third membrane called the thylakoid membrane. It located in the thylakoid membrane of the chloroplast. It is the light-independent reactions take place. The thylakoid membrane absorbs photon energy of different wavelengths of light. Embedded in the thylakoid membranes are photosystems: Clusters of 200 to 300 pigments and other molecules that surround a pair of chlorophyll

Science Lesson 2: Naming and describing the parts of a plant I. Objective: At the end of each lesson, the pupils should be able to name and describe each part of a plant. II. CONTENT AND MATERIALS A. Content: 1. Concept/Ideas The external parts of the different plants are roots, stem, leaves, flower, and fruits. The root is the plant part that grows downward into the ground. The stem is the plant part where leaves and flower grows from. It is usually found above the ground, but

Impact of hypoxia to the catfish industry Oxygen is important for aerobic organisms, especially for fish who live in the aquatic environment with routinely low dissolved oxygen (Wang et al., 2017b). Under aquaculture conditions, hypoxia can be caused by natural phenomena (e.g., weather, temperature, or water flow rate), water pollution and eutrophication, high stocking density, and improper use of aeration (Green et al., 2016; Wu, 2002; Zhang et al., 2010). In spite of the strong tolerance of catfish

serve a pivotal role in maintaining life on earth. With that being said, it begs the question concerning what is going on behind the scenes. It may look like plants just exist, when really they are the reason humans exist. Through the process of photosynthesis, which is the biological process that can capture radiant energy (sunlight) and convert it into chemical compounds (carbohydrates) that every organism uses to power its metabolism (OpenStax 219-220), plants successfully create energy that is used

different angled plants, the angle of growth added with the initial pot’s angle equals out to 180 degree. I really enjoyed this lab because this lab tested my abilities to record data, care for a living organism, and lastly, prepare for labs in the upcoming class. To sum it all up, the hypothesis that plants will grow directly towards its light source proved to be correct. POST LAB QUESTIONS 1) How do living organisms reproduce, grow, and develop? Organisms reproduce when the egg of an organism is fertilized

they go through photosynthesis by using C3 carbon fixation, where CO2 is first incorporated into a 3-carbon compound called PGA, by using the enzyme RUBISCO for carbon fixation and Calvin cycle. Other plants, like pigweeds are called C4 plants because Carbon is first incorporated into a 4-carbon compound activating the PEP enzyme carboxylase for carbon fixation and RUBISCO for the Calvin cycle. The difference between the C3 and C4 species anatomy is in a C3 plant, photosynthesis occurs in a single

Jessica Dador Suzanne Hizer BIO215 ANALYZING THE EFFECTS OF CAFFEINE ON THE GROWTH OF MARIGOLD FLOWERS ABSTRACT: Marigold Snow Drift flowers begin to sprout within one to two weeks and grow anywhere from six inches to three feet in length. Caffeine acts as a stimulant that temporarily increases alertness and energy. The purpose of this experiment is to determine if caffeine has an effect on stimulating and accelerating the growth of Snow Drift Marigold flowers. Fifty Marigold flowers were grown;

Importance of Photosynthesis and Respiration Explain how photosynthesis and respiration are linked in order to provide you with energy from the food you eat: Photosynthesis is the process in which certain life forms are able to use sunlight to create energy. This energy is created by making carbohydrates from carbon dioxide and water in the presence of chlorophyll. Plants release large amounts of oxygen into the atmosphere as they produce much more than needed during the photosynthesis process.
