CHLOROPLASTS

Question 1

INTRO

Answer 1

Chloroplasts are found in plants and algae.

They’re responsible for capturing light energy to make sugars in photosynthesis.

Question 2

PHOTOSYNTHESIS

Answer 2

In photosynthesis, light energy is collected and used to build sugars from carbon dioxide.
The sugars produced in photosynthesis may be used by the plant cell, or may be consumed by animals that eat the plant, such as humans.
The energy contained in these sugars is harvested through a process called cellular respiration, which happens in the mitochondria of both plant and animal cells.

Question 3

STRUCTURE

Answer 3

Chloroplasts are disc-shaped organelles found in the cytosol of a cell.
They have outer and inner membranes with an intermembrane space between them.
it contained membrane discs known as thylakoids, arranged in interconnected stacks called grana (singular, granum).

Question 4

THYLAKOIDS

Answer 4

The membrane of a thylakoid disc contains light-harvesting complexes that include chlorophyll, a pigment that gives plants their green color.
Thylakoid discs are hollow, and the space inside a disc is called the thylakoid space or lumen, while the fluid-filled space surrounding the thylakoids is called the stroma.
