Plastid

Okay kiddo, a plastid is a small structure found inside the cells of plants and algae. Think of it like a tiny specialized room inside a bigger room.

There are different types of plastids. One of them is called a chloroplast, which is like a little factory that makes food for the plant using energy from the sun. It's kind of like a kitchen in a house where food is made.

Another type of plastid is called a chromoplast, which gives color to fruits and flowers. It's like a paint room in a house where things are painted different colors.

Finally, there is also a type of plastid called a leucoplast, which stores starches and oils. It's like a pantry in a house where food is stored for later.

So basically, a plastid is like a tiny, specialized room inside a plant cell that helps with different functions like making food, adding color, and storing important nutrients.
