Question

which table correctly identifies the structure and function for each of the letters in the diagram? letter structure function w membrane controls what can enter and exit the cell x chloroplast converts energy from the sun into food y nucleus controls functions of the cell and contains genetic information z mitochondrion creates energy for the cell letter structure function w mitochondrion converts energy from the sun into food x nucleus controls what can enter and exit the cell y membrane controls functions of the cell and contains genetic information z chloroplast creates energy for the cell

Explanation:

1. Recall cell - structure functions:

• The cell membrane controls what enters and exits the cell.
• Chloroplasts convert solar energy into food through photosynthesis.
• The nucleus controls cell functions and contains genetic information.
• Mitochondria create energy for the cell in the form of ATP.

1. Analyze Option A:

• For letter W, membrane - controls what can enter and exit the cell (correct).
• For letter X, chloroplast - converts energy from the Sun into food (correct).
• For letter Y, nucleus - controls functions of the cell and contains genetic information (correct).
• For letter Z, mitochondrion - creates energy for the cell (correct).

1. Analyze Option B:

• For letter W, mitochondrion does not convert energy from the Sun into food (incorrect). Chloroplasts do this.
• For letter X, the nucleus does not control what enters and exits the cell (incorrect). The membrane does this.
• For letter Y, the membrane does not control cell functions and contain genetic information (incorrect). The nucleus does this.
• For letter Z, chloroplasts do not create energy for the cell in the form of ATP (incorrect). Mitochondria do this.

Answer:

A. Letter W: membrane, controls what can enter and exit the cell; Letter X: chloroplast, converts energy from the Sun into food; Letter Y: nucleus, controls functions of the cell and contains genetic information; Letter Z: mitochondrion, creates energy for the cell
