Learn: Animal and Plant Cells

Welcome!Welcome back! You've already learned about eukaryotes and prokaryotes. Now, let's build on that and explore the structures and functions of animal and plant cells.

What are Animal and Plant Cells?Animal and plant cells are both eukaryotic cells (contain a nucleus and membrane-bound organelles). While they share many features, they also have some key differences. Understanding these differences helps us study their roles in living organisms.

Cell Structures in Animal CellsAnimal cells contain structures called organelles, each performing specific functions. Key organelles include: nucleus (controls activities and stores genetic material), mitochondria (site of respiration), and cell membrane (controls what enters and exits).

Unique Features of Plant CellsPlant cells have additional structures not found in animal cells, such as chloroplasts (site of photosynthesis), cell wall (provides support and structure), and a large central vacuole (stores water and maintains shape).

Chloroplasts: The Powerhouse of PhotosynthesisChloroplasts contain a green pigment called chlorophyll, which absorbs sunlight for photosynthesis. This process allows plants to produce glucose and oxygen.

Microscopy: Studying CellsMicroscopes allow us to observe cell structures in detail. Light microscopes are commonly used in schools, while electron microscopes provide much higher magnification and resolution.

Review Time!Well done! You've learned about the structures of both animal and plant cells, their functions, and how microscopes help us study them. Let's test your understanding with a few questions.
