Cell Definition

Cells are the structural, functional, and biological units of all living beings. A cell can replicate itself independently. Hence, they are known as the building blocks of life. 

Each cell contains a fluid called the cytoplasm, which is enclosed by a membrane. Also present in the cytoplasm are several biomolecules like proteins, nucleic acids and lipids. Moreover, cellular structures called cell organelles are suspended in the cytoplasm.

A plant cell is a tiny building block that makes up plants. It has special parts that help it work.

Important Parts of a Plant Cell

1. Cell Wall —A strong outer layer that protects the cell and gives it shape.

2. Cell Membrane —A thin layer inside the wall that controls what goes in and out.

3. Cytoplasm —A jelly-like substance that holds everything inside the cell.

4. Nucleus —The brain of the cell that tells it what to do.

5. Chloroplasts —Tiny green parts that help the plant make food from sunlight (photosynthesis).

6. Vacuole — A big storage area that holds water, food, and waste.

7. Mitochondria — The part that gives the cell energy, like a tiny power station.

8. Ribosomes —Small dots that make proteins, which help the cell grow and repair.

9. Endoplasmic Reticulum (ER) —A system of tubes that helps move things inside the cell.

10. Golgi Apparatus — Packs and sends out proteins and other materials to different parts of the cell.

11. Plasmodesmata —Small holes in the wall that let cells talk to each other.
