Question

The diagram shows a plant cell.

A plant cell has four structures that are labeled W, X, Y, and Z. Structure W is pointing to the barrier around the cell. Structure X is pointing to an oblong structure containing stacks of green disc-shaped objects. Structure Y is pointing to a large, circular structure near the center of the cell. Structure Z is pointing to a bean-shaped structure containing folded channels.

Which table correctly identifies the structure and function for each of the letters in the diagram?
A.
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

Answer 1

A

Reason: W is the cell membrane (controls what enters/exits), X is a chloroplast (stacks of green thylakoids; photosynthesis), Y is the nucleus (stores DNA and controls the cell), and Z is a mitochondrion (bean-shaped with folded inner membranes; makes ATP).
