Which is the main light-absorbing pigment for photosynthesis?
Photosynthesis occurs in the plant’s chloroplasts, where energy from sunlight is captured and used to start a reaction that produces several products. What is one way that photosynthesis benefits all living things?
Ivan is looking at a cross section of a stem taken from a vascular plant. He sees two different types of vascular tissue: the xylem, which is closer to the center of the stem, and the phloem, located around the xylem, closer to the outside of the stem. How do these two structures work together in a living plant?
Fiona wants to use the scientific method to answer the question “Do oxygen levels in the air affect rates of photosynthesis?” She reads about photosynthesis in her biology book and is ready to carry out the next step. What should she do next?
Which is the first step in the scientific method?
All plants we see today had ancestors that lived in the water. One of the reasons plants began to live on land was
Which is required for the light-independent reactions in photosynthesis to occur?
What is one role of ATP in the light-independent reaction of photosynthesis?
One differentiating characteristic between vascular and nonvascular plants is the lack of active transport structures in the nonvascular plants. How does the lack of xylem or phloem contribute to the smaller size of the nonvascular plants?
Vascular plants have two different types of specialized tissues that transport food, water, and nutrients to the various plant structures. What would be the effect on a vascular plant if the phloem became damaged?
Which statement best describes what a thylakoid does during photosynthesis?
In the chemical equation for photosynthesis, carbon dioxide and water are converted to glucose and oxygen.
6CO2 + 6H2O ® C6H12O6 + 6O2
Which component could be added to complete this chemical equation?
ATP and NADPH
Which is the best description of photophosphorylation?
Which process is catalyzed by rubisco during the light-independent reactions of photosynthesis?
