Concept explainers
To draw: A simple straight line to represent the chloroplast membrane that contains the photosynthetic pigments.
Introduction: Photosynthesis is a process by which carbon dioxide and water are broken down to produce glucose molecules by using energy from sunlight. During this process, oxygen gas is evolved. The reactions of the photosynthesis take place in the chloroplast of the plant cell which contains the green pigment chlorophyll.
To determine: The color of the chloroplast membrane that contains the photosynthetic pigments.

- For the following questions, choose one to discuss: chloroplast/photosynthesis State at the outset which one you will discuss. A) What role do proton gradients play in the process of photosynthesis proton gradients allow B) Where are proton gradients formed? Within what structures are they seen in chloroplasts How do the structures help them to maintain a gradient? C) Explain where and how the chloroplast or mitochondria uses passive transport and active transport to complete photosynthesis or cellular respiration.arrow_forwardCan someone help me understand this. A student set up an experiment to show the effect of light color on photosynthesis in Elodea plants. She filled two test tubes with distilled water and placed a piece of Elodea in each of the tubes. She added a drop of phenol red, which turns red in a basic solution and yellow in an acidic solution. She blew in each tube before placing the volumeters on the top of the tube. Why did she blow into the tube? to add oxygen to the tube to add carbon dioxide to the tube to add carbohydrates to the tube to add sodium bicarbonate to the tubearrow_forwardCreate a meaningful essay using the words provided on the concept map of photosynthesis, specifically the light dependent reaction below.

- A. The C4 plant performs photosynthesis more efficiently than the C3 when the CO2 concentration is 600ppm or less. Provide one reason why the rate of photosynthesis doesn’t change for the C4 plant when the CO2 concentration increases above 400 ppm. B. Discuss what is happening in the C3 plant when the CO2 levels are below 50 ppm. Provide one reason why this does NOT happen to the C4 plant.arrow_forwardecplain Two types of photosystems cooperate in the light reactions and the imagearrow_forwardIdentify the chemical basis for ApH and AY across the chloroplast thylakoid membrane by dragging the descriptions to their targets.

- What properties of photosynthetic pigments allow pigments to absorb light of only certain wavelengths? Select all that apply. Some pigment molecules lack a light-trapping region. Light of any energy level can boost an electron of the pigment molecule to a higher energy level in order to be absorbed. Only light with the correct wavelength to boost an electron of the pigment to a higher energy level is absorbed. All pigment molecules possess a light-trapping region with a special structure that allows electrons to move freely between its atoms.arrow_forwardPhotosystems are essential to the light reactions. Which of the following is true about photosystems? * Photosystems are embedded within membranes, across which they create a proton gradient. Photosystems work together to absorb light over a larger surface area than could be possible from just one pigment molecule working alone. O Photosystems are composed of proteins and pigment molecules. All of the abovearrow_forwardThis molecule: • is contained in the thylakoid membrane of chloroplasts • convert sunlight energy into ATP • Reflects green wavelengths of light. _______?arrow_forward
