B9 Review Photosynthesis & Plants

The diagram below represents a cell of a green plant.
Solar energy is used to produce energy-rich compounds in structure

• A
• B
• C
• D

The arrows in the diagram below represent the movement of materials.
This movement of materials indicated by the arrows is most directly involved in the processes of

• respiration and replication
• photosynthesis and excretion
• digestion and recycling
• circulation and coordination

As it grows from a seed to a mature plant, a plant will grow taller and thicker. Which are abiotic factors most responsible for the increase in the mass of the plant?

• water, minerals, bacteria
• sunlight, oxygen, plant receptors
• minerals, water, plant enzymes
• water, sunlight, carbon dioxide

The chart below lists substances involved in the process of photosynthesis.
Which statement best describes how these substances interact in photosynthesis?

• A and B combine to produce C and D.
• B and C combine to produce A and D.
• C and D combine to produce A and B.
• A and C combine to produce B and D.

Which statement is a valid inference concerning structure X represented in the diagram below?

• Structure X contains guard cells that regulate glucose intake.
• Structure X carries out heterotrophic nutrition.
• Structure X produces gametes for asexual reproduction.
• Structure X transports materials for metabolic activities.

Which process is most closely associated with the regulation of water loss from the leaves of trees?

• digestion of water within the cytoplasm in the leaf cells of the trees
• synthesis of protein by the chloroplasts in the leaf cells of the trees
• movement of water through leaf openings controlled by the guard cells
• absorption of nitrogen through leaf openings controlled by the guard cells

Which process uses energy to combine inorganic molecules to synthesize organic molecules?

• respiration
• digestion
• photosynthesis
• decomposition

Photosynthesis and respiration are alike in that they both

• require the Sun as a direct source of energy
• result in the production of glucose molecules
• require specific catalysts
• occur within mitochondria

The diagram 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
• close the stomate to keep dust and dirt out of the leaf
• directly provide leaf cells with the water involved in photosynthesis
• allow newly formed glucose to be released from the leaf

Which phrase is an example of autotrophic nutrition?

• a cow eating grass in a field
• a mushroom digesting a dead log
• an apple tree making its own food
• a tapeworm feeding in the body of a dog
