Chloroplasts and Photosynthesis Organelles

Chloroplasts are the organelles responsible for photosynthesis in plant cells. They contain a specific green pigment that absorbs light energy.

What is this pigment called?

Chloroplasts contain more than one type of pigment. Besides chlorophyll, they also contain accessory pigments that assist in capturing light.

In addition to chlorophyll, chloroplasts also contain 1($), which are yellow and orange accessory pigments.

Chloroplasts have a complex internal membrane system. Match each structure to its correct description.

Chloroplasts have a complex internal membrane system. Match each structure to its correct description.

Inside the chloroplast, surrounding all the internal membrane structures, is a protein-rich fluid.

This fluid matrix is called the 1($).

Inside the chloroplast, the internal membrane system is organized into distinct stacked structures where the light-capturing reactions take place.

What are these stacks called?

Plastids are a family of plant cell organelles. Drag each plastid type into the correct category based on its contents.

Plastids are a family of plant cell organelles. Drag each plastid type into the correct category based on its contents.

Both chloroplasts and mitochondria are major organelles found in plant cells. How do they compare in size?

Photosynthesis occurs in two main stages inside the chloroplast. Arrange the following steps in the correct sequence.

Select ALL statements that are correct about chloroplasts.

Complete the following description of chloroplast internal structure:

Inside the chloroplast, stacks of disc-like sacs called 1($) are embedded in a protein-rich fluid called the 2($). The membranes within the stacks are called 3($), while the membranes connecting different stacks are called 4($).
