Margie illustrated the process of photosynthesis, as shown, Which mistake did she make?

• The arrow for sugar should point away from the plant.

• The arrow for carbon dioxide should point away from the plant.

• The arrows for carbon dioxide and sugar should point away from the plant.

• 
  The arrow for carbon dioxide should point away from the plant and the arrow for oxygen should point toward the plant.

The rate of photosynthesis can be determined by measuring the rate that raw materials are used up by a plant or by measuring the rate that products of photosynthesis are produced by a plant. 

How does placing a plant in a dark room for 24 hours affect the rate of photosynthesis?

• The rate of photosynthesis increases and the plant takes in more water.

• The rate of photosynthesis decreases and the plant produces more sugar.

• The rate of photosynthesis increases and the plant produces more oxygen.

• The rate of photosynthesis decreases and the plant takes in less carbon dioxide.

Photosynthesis allows a plant to harvest energy from light and convert it into a form of energy that can be used by living things. What form of energy does photosynthesis convert light energy into?

When sunlight strikes a plant, the leaves capture most of that energy to use photosynthesis. The below shows the process of photosynthesis.

How do plants obtain the water and carbon dioxide they use for this process?

• Carbon dioxide is absorbed from oxygen and water is taken in by the stems

• 
  Water enters through the roots and carbon dioxide enters through the leaves

• 
  Water enters as rain falls on the stems and carbon dioxide is absorbed from fertilizer

• Carbon dioxide is absorbed through the roots and the leaves absorb water from the air

• Cellular respiration

• Chloroplasts

• Mitochondria

How do organisms get the energy they need?

• Plants produce their own energy through photosynthesis, and animals get energy from eating other organisms

• Plants do not require energy because they do not move, and animals get energy by performing exercise

• Plants get energy from glucose produced in the soil, and animals get energy directly from sunlight

• Plants get energy from fertilizers, and animals get energy by drinking water

Plant cells contain a green pigment called chlorophyll. Chlorophyll has a role in the process of photosynthesis. What does chlorophyll do?

• Produces glucose from oxygen

• Produces oxygen from glucose

• Absorbs light energy from the sun

• Absorbs glucose from the storage in the plant

A scientist is investigating the rate of cellular respiration when a person is exercising and when at rest.  How would the amount of gas released be different in these two situations?

• 
  Less oxygen would be released when exercising than when at rest.

• More oxygen would be released when exercising than when at rest.

• More carbon dioxide would be released when exercising than when at rest.

• Less carbon dioxide would be released when exercising than when at rest.

Many athletes use altitude training to improve their performance. They travel to areas of high altitude where there is less oxygen in the air. The body adapts to the stress of less oxygen by becoming more efficient at transporting and using oxygen.

What are athletes who train in high altitudes  most likely trying to enhance?

• building of muscle tissue

• pH balance of red blood cells

• enhancement of the nervous system

• energy production in the mitochondria
