Answer 1

To determine the correct identification of the structure and function for each part of a plant cell, we first need to understand the roles of the different organelles:

1. Cell Membrane: Controls what can enter and exit the cell.
2. Chloroplast: Converts energy from the sun into food (photosynthesis).
3. Nucleus: Controls functions of the cell and contains genetic information (DNA).
4. Mitochondrion: Creates energy for the cell (ATP through cellular respiration).

Now, evaluating each option:

A

• W: Membrane - Correct function (controls what can enter and exit the cell)
• X: Chloroplast - Correct function (converts energy from the Sun into food)
• Y: Nucleus - Correct function (controls functions of the cell and contains genetic information)
• Z: Mitochondrion - Correct function (creates energy for the cell)

This table is correct.

B

• W: Mitochondrion - Incorrect function (mitochondrion does not convert energy from the Sun)
• X: Nucleus - Incorrect function (nucleus does not control what enters/exits the cell)
• Y: Membrane - Incorrect function (membrane does not control functions of the cell or contain genetic info)
• Z: Chloroplast - Incorrect function (chloroplast does not create energy for the cell)

This table is incorrect.

C

• W: Membrane - Incorrect function (membrane does not control functions of the cell or contain genetic info)
• X: Mitochondrion - Correct function (creates energy for the cell)
• Y: Chloroplast - Incorrect function (chloroplast does not control what enters/exits the cell)
• Z: Nucleus - Incorrect function (nucleus does not convert energy from the Sun)

This table is incorrect.

D

• W: Mitochondrion - Incorrect function (mitochondrion does not control functions of the cell or contain genetic info)
• X: Chloroplast - Correct function (converts energy from the Sun into food)
• Y: Nucleus - Incorrect function (nucleus does not control what enters/exits the cell)
• Z: Membrane - Incorrect function (membrane does not create energy for the cell)

This table is incorrect.

Given this analysis, the correct answer is A, as it accurately identifies the structure and function of each part of the plant cell.
