Core Cell Structures
Your cell membrane acts like a bouncer at a club - it decides what gets in and what stays out of every single cell. This selective barrier is found in animal, plant, and fungal cells, making it one of the most universal cellular structures.
The nucleus is essentially the cell's control centre, much like the brain in your body. It stores all the genetic information and controls what the cell does throughout its life. You'll find this command centre in animal, plant, and fungal cells.
Inside the cell, the cytoplasm provides the perfect environment for chemical reactions to occur. Think of it as the cell's workshop where most of the important cellular processes happen. The mitochondrion is where aerobic respiration takes place - this is how cells release energy from glucose to power themselves.
Quick Tip: Remember that mitochondria are often called "powerhouses of the cell" because they produce the energy (ATP) that cells need to function!
