Plant System Quiz

What energy is need to initiate the process of photosynthesis?

• Sun
• Heat
• Electrical
• Glucose

What is produced when the process of photosynthesis is complete?

• carbon dioxide and water
• radiant and thermal energy
• glucose and oxygen
• glucose only

What gas is needed to initiate the process of photosynthesis?

• carbon dioxide
• oxygen
• hydrogen
• air

The arrow in the chemical equation of photosynthesis represents-

• no energy is transferred
• thermal energy
• chemical reaction
• radiant energy

The roots of the plant to the right are exhibiting which behavior?

• Phototropism
• Hydrotropism
• Geotropsim
• Thigmotropism

The picture below shows a change in turgor pressure called wilting in a plant. Which statement best describes what has happened between picture A and B?

• Water increased the turgor pressure in the cells of the flower.
• Water entering and leaving the cells of the flower at equal rates kept turgor pressure equal.
• Lack of water in the soil decreased the turgor pressure in the cells of the flower.
• Lack of sunlight on a cloudy day caused the flower to lose turgor pressure.

When a plant is emerging from a seed, it is because

• it has enough sunlight
• it is lacking water
• it turgor pressure has build up and forced the seed's coat open
• it has plenty of carbon dioxide

How does a seed emerge from the soil as a seedling?

• Soil erodes so the seed gets more sunlight
• Animal digs is up disrupting the soil
• Seed must exert a force tp push the shoot up through the soil
• A plant must die in order to make room for the new plant

What is thigmotropism?

• growth of a plant in response to light direction
• growth of a plant in response to water
• growth of a plant in response to gravity
• growth of a plant in response to touch/contact

Plants are living organisms, like humans, have cells at different levels to form a complex system. Which of the following lists these levels in the correct order of organization from the simplest to the most complex?

• Organs, organ systems, organisms, cells, tissues
• Tissues, cells, organs, organisms, organ systems
• Organisms, organ systems, organs, tissues, cells
• Cells, tissues, organs, organ systems, organisms
