Plant cells refer to the basic structural and functional units of plants. These cells are eukaryotic, which means they have a nucleus and other membrane-bound organelles such as mitochondria, endoplasmic reticulum, Golgi apparatus, and ribosomes.
Plant cells differ from animal cells in several ways. For example, plant cells have a cell wall made of cellulose that provides structural support and protection, while animal cells do not. Additionally, plant cells contain chloroplasts for photosynthesis, which is the process by which plants convert sunlight into energy through the production of glucose from carbon dioxide and water.
In summary, "plant cells" refers to the fundamental building blocks that make up a plant's body, each containing unique features that allow them to carry out their specific functions effectively.
