What is the difference between a plant and amoeba?

Plants are multicellular organisms that perform photosynthesis to produce their own food using sunlight, water, and carbon dioxide, while amoebas are single-celled, heterotrophic organisms that consume food by engulfing it through a process called phagocytosis. Plants have a rigid cell wall made of cellulose, whereas amoebas have a flexible cell membrane and can change shape. Additionally, plants are typically stationary and rooted in one place, whereas amoebas are mobile and can move through their environment using pseudopodia.
