C and D combine to produce A and B.
The diagram to the right represents a cell of a green plant. Solar energy is used to produce energy-rich compounds in structur
D
Which statement best describes cellular respiration?
It converts energy in food into a more usable form.
Which activity occurs in the process of photosynthesis?
Light energy is converted into the chemical energy of organic molecules
The diagram below represents events associated with a biochemical process that occurs in some organisms. Which statement concerning this process is correct?
The process represented is photosynthesis and the primary source of energy for the process is the Sun.
Organisms that have the ability to use an atmospheric gas to produce an organic nutrient are known as
autotrophs
What types of organisms perform photosynthesis?
autotrophs/producers
equation for photosynthesis
c02 + h20 + sunlight→02 + glucose
. A biological process that occurs in plants is represented below. Which row in the chart below identifies the lettered substances in this process?
carbon dioxide glucose oxygen enzymes
The diagram below represents a cycling of materials. Which row in the chart below shows the substances represented by X and Y?
carbon dioxide oxygen
equation for photosynthesis.
carbon dioxide + water + light energy → glucose + oxygen
The arrows in the diagram could represent the release of
carbon dioxide from a mitochondrion carrying out respiration
The diagram below represents an autotrophic cell. For the process of autotrophic nutrition, the arrow labeled A would most likely represent the direction of movement of
carbon dioxide, water, and solar energy
The diagram to the right represents specialized cells in the surface of the leaf of a green plant. The main function of these cells is to
change the size of the stomate to regulate water loss
During the process of cellular respiration, energy is released from
chemical bonds
During the process of photosynthesis, energy from the Sun is converted into
chemical energy in the bonds of organic molecules
During the process of photosynthesis, energy from the Sun is converted into
chemical energy in the bonds of organic molecules EX: Glucose
The diagram to the right illustrates the movement of materials involved in a process that is vital for the energy needs of organisms. The process illustrated occurs within
chloroplasts
Other Equation photosynthesis
co2+h20+sunlight=c6h1206+02

glucose O2 enzymes CO2
The buildup of waste products in muscle cells that are active might cause
increased fatigue
Which process is most closely associated with the regulation of water loss from the leaves of trees?
movement of water through leaf openings controlled by the guard cells
The energy found in ATP molecules synthesized in animal cells comes directly from
organic molecules
An inorganic molecule required by green plants for the process of photosynthesis is
oxygen
Which substance is needed for aerobic cellular respiration to occur?
oxygen
Which process uses energy to combine inorganic molecules to synthesize organic molecules?
photosynthesis
The arrows in the diagram to the right represent the movement of materials. This movement of materials indicated by the arrows is most directly involved in the processes of
photosynthesis and excretion
Which organisms and set of characteristics are correctly paired?
plants— carry out respiration and autotrophic nutrition
The main result of cellular respiration is the
production of ATP from the breakdown of glucose
Photosynthesis and respiration are alike in that they both
require specific catalysts
Which two processes are responsible for keeping the percentage of atmospheric oxygen at relatively constant levels?
respiration and photosynthesis
The mass of some corn plants at the end of their growth period was 6 tons per acre. Most of this mass was produced from
water from the soil and carbon dioxide from the air
