Learn: Animal & Plant Cells

Welcome!You've already learned about eukaryotes and prokaryotes. Today, we'll dive deeper into the structure of animal and plant cells and how their components help them function.

Introduction to Animal and Plant CellsBoth animal and plant cells are types of eukaryotic cells, meaning they have a nucleus and membrane-bound organelles. Although they share many features, plant cells have some structures that animal cells don’t, which help them carry out photosynthesis and support their structure.

Animal Cell ComponentsAn animal cell has a cell membrane, cytoplasm, nucleus, mitochondria, and ribosomes. Each of these plays a specific role in keeping the cell functioning properly.

Plant Cell ComponentsPlant cells contain the same structures as animal cells, but they also have additional ones: a cell wall, chloroplasts, and a large vacuole. These structures are essential for processes like photosynthesis and providing support to the plant.

The NucleusThe nucleus is the control centre of the cell. It contains the cell’s DNA, which holds instructions for making proteins and controlling cell activities.

MitochondriaMitochondria are the powerhouse of the cell. They are where aerobic respiration occurs, releasing energy for the cell to use. The energy is stored as a molecule called ATP.

ChloroplastsChloroplasts are found in plant cells and are the site of photosynthesis. They contain the green pigment chlorophyll, which traps light energy for the plant to make glucose.

Cell WallThe cell wall is a rigid structure found in plant cells. It provides support and protection, helping the cell maintain its shape.
