A tissue that comes into contact with the outer world. Found in animals and plants 1 of 21 What is mesophyll? A tissue found in plants that is capable of photosynthesis 2 of 21 What is the epidermal tissue? Human skin, and the waxy covering of some plants are examples of epidermal tissues. Found in animals and plants 3 of 21 What is the muscular tissue? Tissue found in animals that can contract to bring about force and motion. 4 of 21 What are cells? Cells are the building blocks of life for organisms. 5 of 21 What are tissues? Tissues are groups of similar cells that act together to perform a similar function. 6 of 21 What is an organ? Tissues are groups of similar cells that act together to perform a similar function. 7 of 21 What are the three tissues found in the stomach? The epithelial tissue, the glandular tissue and the muscular tissue 8 of 21 How does the glandular tissue help the stomach? It produces digestive juices that break down the stomachs content. 9 of 21 How does the epithelial tissue aid the stomach? It lines it. 10 of 21 How does the muscular tissue aid the stomach? It moves the contents of the stomach during digestion 11 of 21 Which organs are in the digestive system? Small intestine, large intestine, stomach, glands and liver 12 of 21 What does the small intestine do? Digests food and absorb soluble food molecules 13 of 21 What does the stomach do? Digest food 14 of 21 What does the large intestine do? It absorbs water molecules from the remaining undigested food. This allows it to produce faeces. 15 of 21 What do glands do? Produce digestive juices 16 of 21 What does the liver do? Produce bile 17 of 21 What is an organ system? Organ systems are groups of organs that work together to perform a particular role. 18 of 21 Give an example of an organ system. The digestive system 19 of 21 What is an organism? An organism is the highest level of organisation in a multicellular organism, consisting of several organ systems. 20 of 21 What are the levels organisation in ascending levels of complexity? 1. Cells 2. Tissues 3. Organs 4. Organ systems 5. Organisms 21 of 21
