Photosynthesis

Master photosynthesis with our engaging worksheet! Learn about chloroplasts, light reactions, and more.

Fill in the blanks below In photosynthesis, light energy from the sun is converted into chemical energy What types of organisms perform photosynthesis? Select ALL that apply. Plants Algae Animals Protists Fungi Cyanobacteria Fill in the blank below Photosynthesis occurs in the chloroplast organelle in plants. Which pigment below is found in the thylakoid of plants and is responsible for their green color? Carotenoid Anthocyanin Chlorophyll Fill in the blank below Pigments are structures that absorb wavelengths of color. Whichever wavelengths are not absorbed are reflected back. Receptors in our eyes absorb these reflected wavelengths and our brain interprets them as the objects color! Which wavelenght(s) of sun light can be used in photosynthesis? Visible light UV Infrared X-rays Radio waves Gamma rays Organize the following items as photosynthesis reactants or products Reactants Water Carbon Dioxide Light Products Glucose Oxygen The reactions of photosynthesis are divided into two categories.What are they? light-dependent reactions and Citric acid cycle. Carbon fixation reactions and oxygen fixation reactions. chemiosmosis and photochemical reactions. light-dependent reactions and Calvin Cycle Match the part of the chloroplast with their functions. granum stack of thylakoids thylakoid photosynthetic membranes and the site of the light reactions stroma fluid portion of the chloroplast and the site of the calvin reactions. outer and inner membrane surround the outside of the chloroplast lumen the inside of the thylakoid Fill in the blanks from text word bank. The light dependent reactions require sunlight and occur in the thylakoids. Water is a reactant and oxygenis the product.The calvin cycle does not require sunlight and occurs in the stroma. Carbon dioxide is a reactant and glucose is the product.Two reactions of photosynthesis are linked by molecules. First one is called (known as energy) ATPand the other one is NADPH. Photosynthesis is a redox (oxidation-reduction) process. •Reduction: CO2 becomes reduced to sugar as electrons along with hydrogen ions from water are added to it.•Oxidation: Water molecules are oxidized when they lose electrons along with hydrogen ions. Scientists have known since the 1800s that plants produce O2. Where does this oxygen come from ? carbon dioxide water The graph below represents the absorption spectrum of chlorophyll.The graph indicates that the energy used in photosynthesis is most likely obtained from which regions of the spectrum? yellow and orange red orange red and violet blue violet blue and green green and yellow Use the following diagram to answer question. The diagram represents a cross section of a leaf.The largest amount of carbohydrates would be manufactured by structures; A-C B-C A-D B-D Which structures are not found in stroma? Pigments DNA Ribosome Photosystems RNA Starch
