Plant cell as the functional unit of plants: The basic structural and functional unit of plants, responsible for all physiological processes. Like all living organisms, plants rely on their cells to sustain life functions, growth, and development.
Protoplast: The cell without its cell wall, consisting of the plasma membrane and the enclosed cytoplasm and organelles. It represents the living part of the cell capable of metabolic activity (source content).
Protoplasm: The living substance within the protoplast, composed of cytoplasm and organelles. It is essential for cellular functions such as metabolism, growth, and reproduction (source content).
Presence of various organelles including plasma membrane: Plant cells contain multiple organelles (e.g., nucleus, chloroplasts, mitochondria) enclosed within the plasma membrane, which regulates the exchange of substances and signals between the cell and its environment (source content).
