Organelle that manages or controls all the cell functions in a eukaryotic cell. Contains chlorophyll, a green pigment that traps energy from sunlight and gives plants their green color. Digests excess or worn-out cell parts, food particles and invading viruses or bacteria.

A thick, tough, layer outside the cell membrane called the cell wall. It is made of the material cellulose. The cell wall helps the cell keep its shape, and stops it bursting when the cell is placed in water. Mature plant cells have a large central vacuole, surrounded by a membrane, and filled with a watery
The cell wall is a rigid structure that surrounds cells in plants, algae and fungi. It’s made mainly of the carbohydrate cellulose in plant and algae cells. In fungi, the cell wall is made of chitin. Its primary function is to support cells and prevent them from changing shape.
Cells contain organelles which have functions. Bacterial cells are different from animal and plant cells as they have no organelles which have membranes and their cell wall is chemically different. Fungi have a cell wall which is not made of cellulose. Bacteria have plasmids and circular DNA.

These worksheets will help you learn more about all the organelles found within cells. We start by exploring the main structures that function to keep the basic units of life thriving. We investigate how they interact and the movement of substances within the plasma membrane.
