This science lesson explores the distinctions between plants and animals by examining seven life processes, remembered through the mnemonic “Mrs. Gren”: Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion, and Nutrition. While both plants and animals exhibit these processes, differences include body structure and movement methods, as plants have a branching body and can tilt to the sun, whereas animals have a defined form and move to find shelter or food. Additionally, plants produce food through photosynthesis, unlike animals which rely on consuming organic matter from other organisms.
