Endocytosis and exocytosis are really interesting ways that cells talk to each other and interact with what’s around them. Let’s break down how they work:

Endocytosis:

• What it is: This is when cells take in things from outside by wrapping them in their membrane.
• Why it matters: This process lets cells grab important signals and nutrients. For example, they can bring in molecules like hormones, which help send messages in the body.

Exocytosis:

• What it is: This is the opposite of endocytosis. Here, cells push substances out by packing them in tiny bubbles called vesicles that join with the cell membrane.
• Why it matters: This helps cells send out signals, like hormones or proteins, to talk to other cells.

Together, these processes help cells respond to changes around them. They also keep the communication going, which is really important for growth and helping our immune system work!
