Nutrition and Cellular Energy in Plants and Animals

Apuntes

Okay, here is the transcription and explanation of the content from the images, presented in English, focusing on clarity and understanding. The material covers Nutrition in Living Beings. Nutrition in Living Beings Nutrition is a basic living need. During the nutrition process, living beings require substances called nutrients, which are essential to build the body, regulate or repair tissues, and provide energy. Ways How Living Beings Get Their Nutrients There are different ways organisms acquire their nutrients: 1. Fungi: • They release digestive enzymes externally. • These proteins (enzymes) break down big molecules into smaller forms. • Cells then absorb these smaller nutrients. • They can also absorb nutrients directly through diffusion. 2. Plants: • Photosynthesis – Production of sugar: They use sunlight, water, and carbon dioxide to produce their own food (sugar) and oxygen. • Absorption: They absorb water and minerals from the soil through their roots. 3. Animals: • Ingestion-absorption: They consume food and then digest and absorb the nutrients. This involves feeding on other organisms to obtain the necessary energy and substances.
