In a Plant Cell
A cell has many different parts to it, which are called organelles.

What Are Organelles?
The organelles of a cell are important. They each have a different purpose to help the cell grow and develop well. They are like the organs in our body, which helps us grow and get big.
Let me take you on a trip inside a plant cell together!
Nucleus
Nucleus is the most important part of a cell. It is a cell structure that contains nucleic acids, the chemical instructions that direct all the cell's activities.
Nucleolus is a small structure that produces ribosomes.
Nucleolus
What Are Cells?
Cells are the basic units of structure and function in living things. They are the building blocks of life, just like how bricks are the building blocks of buildings, houses and ect.
All the things that are alive, are made up of cells. Such as humans, animals,plants and ect. Cells are really small, which we need a microscope to see it.
Cell Membrane
Cell membrane is a cell structure that protects the cell and controls what substances come into and out of the cell.
Cytoplasm
Cytoplasm is the area between the nucleus and the cell membrane. It contains a gel-like fluid that fills in the cell. Many different organelles are found in it.
Plant cell
Ribosomes
Ribosomes are small structures that maybe attached to the endoplasmic reticulum or floating in the cytoplasm. It functions as factories to produce proteins.
Mitochondria
Mitochondria are rod-shaped cell structures. They provide the energy that a cell needs to carry out its functions.
Vacuole is a large sac filled with water, inside a cell that act as a storage area.
It stores food, water, waste product, and other materials needed by the cell. When a vacuole is full of water, it make cell plump and firm. And plant wilts without much water in the vacuoles.
Vacuole
Golgi Bodies
Golgi bodies are like flatten collections of sacs and tubes. They package proteins and other materials that comes from the endoplasmic reticulum and distributes them to other parts of the cell. They also release materials outside the cell.
Endoplasmic Reticulum
Endoplasmic reticulum is a structure that forms a network of passageways, that carries proteins and other materials from one part of the cell to another.
Lysosomes
Lysosmes are small round cell structures that contains chemicals that break down food particles and worn-out cell parts. They are more common in animal cells than in plant cells.
Cell Wall
Cell wall is a rigid layer of nonliving material that encloses the cells of plants and some other organisms. It protects and supports the cell. It also provides and maintains the shape of the cell.
Only the cells of a plant and some other organisms have cell walls.
Videos
Chloroplasts
Chloroplasts are green structures that captures energy from sunlight to produce food for the cell. Only plant cells and some other organisms have these structures.
Chromatin
Chromatin is a material in cells that contains DNA ans carries genetic information.
You first enter through the cell wall.
As you pass through the cell wall, you then come across the cell membrane.
After passing through the cell membrane, you now find yourself in the cytoplasm.
As you pass into the cytoplasm, you will see mitochondria appearing.
While you go farther into the cytoplasm, the large vacuole floating in the cytoplasm comes into view.
While you keep on going, you will find ribosomes.
When you move pass the lysosomes, you will see Golgi Bodies.
As you still travel farther into the cytoplasm, you will notice chloroplasts floating in the cytoplasm.
Before you move on, see if you missed something. Oops, you missed lysosomes.
As you pass ribosomes, endoplasmic reticulum comes into view.
After going through the endoplasmic reticulum, you will next encounter the brain of the cell, the nucleus.
The trip is not done yet!
Now you go inside the nucleus.
When you go inside the nucleus, you see chromatin floating directly ahead in the nucleus.
As you plan to leave the nucleus, you will then spot nucleolus floating by.
You are almost done with your trip, but now you will have to get out of the nucleus and travel back the same way you came inside. Then you will finally be done with your journey.
