The diagram below represents a cell in the human body. Which statement concerning the structures within this cell is accurate?

• Structure 1 is a chloroplast that carries out photosynthesis

• Structure 2 is a vacuole that contains DNA.

• Structure 3 is a mitochondrion, where respiration takes place

• Structure 4 is the cell membrane, which provides rigid support for the cell.

The diagram represents a germinating bean seed that has been split open. Plants are able to continue to grow and develop once the starch supply in the seed is gone, because they

• develop roots to absorb starch from the

  environment

• grow leaves, which use light energy for cell

  respiration

• have chloroplasts and use light energy to

  make more food

• produce more seeds, which contain additional

  food reserves
