Bio 100 EXAM 2 STUDY GUIDE CH 5 THE WORKING CELL 1. Properties of plasma membranes – fluid mosaic a. Lipids do what –Make up the phospholipid bilayer b. Proteins do what –embedded in lipid bilayer. Transports molecules across the membrane 2. Diffusion – movement down concentration gradient – Molecules move from HIGH concentration to LOW concentration until equilibrium is achieved 3. Passive transport/simple diffusion – diffusion across membrane. Needs no energy, energy

1. 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

involves osmosis; which is the diffusion of water from a high concentration to a lower concentration through a partially permeable membrane, until both the concentrations are equally saturated. All these factors i.e. transpiration and photosynthesis, come together to confirm my hypothesis. To support my hypothesis further, I did a pilot study in a meadow in which I studied the population of certain plant species in areas of different light intensities. I learned that different plants

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
