Cell Structure
Muhtasari
Every living organism, from a bacterium in the soil to a blue whale crossing the ocean, is built from cells. These tiny units carry out all the chemical reactions that keep life going, and each one contains a precise arrangement of structures that make those reactions possible.
In this lesson you will learn the key structures found inside animal and plant cells, what each one does, and how to spot the differences between the two cell types. These foundations come up in almost every biology topic that follows, so getting them right now pays off across the whole course.
Malengo
- Describe cell structures, including the nucleus, cytoplasm, cell membrane, cell wall, mitochondria, chloroplasts, ribosomes and vacuole
- Describe the functions of the nucleus, cytoplasm, cell membrane, cell wall, mitochondria, chloroplasts, ribosomes and vacuole
- Know the similarities and differences in the structure of plant and animal cells
