Introduction

Chloroplasts and cell walls are found in plant cells and not in animal cells. They are specialized structures that allow plants to function as autotrophs. Plants can make their own food by combining inorganic substances by using energy from the sun. The cell wall gives the plant structure.

Chloroplasts are organelles found only in plants and protists which are specialized at capturing energy from sunlight and converting it to chemical energy stored in glucose molecules (glucose).

Let’s take a closer look at these energy-capturing organelles and the plant cell wall now…

The following is a video on the plant cell wall and some differences between plant and animal cells.

Summary

Chloroplasts are plant (and protista)-specific organelles enclosed by a double membrane.

Chloroplasts are specialized at capturing energy from sunlight and converting it to chemical energy which is then stored in sugar molecules (glucose) through a process called photosynthesis.

Plant cell walls are located outside the plasma membrane in plant cells. They are composed of cellulose which is a long chain of glucose molecules bonded together.
