BiologyCells, tissues and organsIGCSEAQA Created by: Josh WilliamsCreated on: 18-04-13 20:58 Organisation Tissue- A group of cells with similar structure and function. Organ- Made of tissues, may contain several tissues. Organ system- Groups of organs that perform a certain function 1 of 3 Animal Tissues,Organs and Systems Animal Tissues include: Muscular Tissue-Contracts to bring about movement Glandular Tissue-Produces substances like enzymes and hormones Epithelial Tissue-Covers some parts of the body An Animal Organ example is the stomach, which contains: Muscular Tissue-To allow contents to move through the digestive system Glandular Tissue-To produce digestive juices Epithelial Tissue-To cover the outside and the inside of the stomach. An example of an Animal Organ System is the Digestive system, which includes: Glands like the pancreas and salivary glands to produce digestive juices The stomach and small intestine where digestion occurs The liver, which produces bile The small intestine, where soluble food is absorbed The large intestine, where water is absorbed from undigested food, producing faeces. 2 of 3 Plant Tissues, Organs and Systems Examples of plant tissues include: Epidermal Tissues, which cover the plant Palisade Mesophylll, which carries out photosynthesis Spongy Mesophyll, which has air spaces to facilitate diffusion of gases The Xylem and Phloem, which transport substances around the plant Fairly obviously, the plant organs include roots, the stem and the leaves 3 of 3
