ARTH 1102 Lecture Notes - Lecture 12: Lysosome, Multicellular Organism, Chloroplast
Document Summary
Their function is to break down lipids, carbohydrates, and proteins from food into particles that can be used by the rest of the cell. Vacuoles: saclike structures where materials such as water, salts, proteins, and carbohydrates are stored by cells. Chloroplasts: (animals and fungal cells do not contain chloroplast) use the energy from food to make high-energy compounds that the cell can use to power growth, development, and movement. Cells in multicellular organisms are specialized to perform particular functions within the organism. The levels of organization in a multicellular organism are individual cells, tissues, organs and organ systems. Tissue: group of similar cells that perform a particular function. Organ system: a group of organs that work together to perform a specific function. Most multicellular organisms have 4 types of tissue: muscle, nervous, connective and. Endoplasmic reticulum provides surface for chemical activity. Centrioles are structures involved in mitosis in animal cells only.
