Plant Cell Theory

Plant Cell Theory is a fundamental concept in biology that states all plants are made up of cells, which are the basic building blocks of life. Each plant cell has a distinct structure, including a cell wall that provides support, chloroplasts for photosynthesis, and a central vacuole for storage and maintaining shape. This theory emphasizes that plants grow, develop, and function through the activity of these cells. Understanding plant cell theory helps explain how plants interact with their environment and play vital roles in ecosystems, such as producing oxygen and serving as food sources.
