LEARNING SITUATION 0 Levels of organisation in Biology WHAT DO YOU  REMEMBER ? LETʼS PLAY A KAHOOT!! LEVELS OF ORGANISATION WHAT DO YOU THINK IS THE SMALLEST UNIT OF LIFE? LEVELS OF ORGANISATION IN BIOLOGY  IN YOUR NOTEBOOK… You must create a  scheme It must include the different levels of organisation (from smaller to bigger) It must include 2 examples of each level of organisation Here you have a link to the information TYPES OF TISSUES TYPES OF TISSUES  Bone tissue CONNECTIVE TISSUE MUSCLE TISSUE NERVOUS TISSUE EPITHELIAL TISSUE Connective tissue Cardiac muscle Covering and proper Adipose tissue tissue Skeletal lining epithelium Cartilaginous tissue muscle tissue Glandular epithelium Smooth muscle Blood tissue tissue CONNECTIVE TISSUE It consists of different types of cells immersed in a gel-like substance called the extracellular matrix. CONNECTIVE TISSUE PROPER FUNCTION: the connective tissue connects, supports and protects other types of tissue. It makes up the dermis, tendons and ligaments. CONNECTIVE TISSUE It consists of different types of cells immersed in a gel-like substance called the extracellular matrix. ADIPOSE TISSUE FUNCTION: it stores energy in the form of lipids in cells called adipocytes. It helps to cushion and insulate the body. Under the microscope it looks like white round spaces divided by lines. CONNECTIVE TISSUE It consists of different types of cells immersed in CARTILAGINOUS TISSUE a gel-like substance called the extracellular matrix. FUNCTION: it supports the skeleton by forming cartilage. Under the microscope they look like a gruyere cheese. chondrocytes CONNECTIVE TISSUE It consists of different types of cells immersed in a gel-like substance called the extracellular matrix. BLOOD TISSUE FUNCTION: it transports nutrients, oxygen and waste products. It is also involved in blood clotting and the immune response. CONNECTIVE TISSUE It consists of different types of cells immersed in a gel-like substance called the extracellular matrix. BONE TISSUE FUNCTION: it forms bones and supports the body. Under the microscope, it looks like the rings of a tree. EPITHELIAL TISSUE Epithelial cells are tightly packed together to form barriers between the body and the external environment, and between distinct internal environments within the body. GLANDULAR EPITHELIUM It contains secretory cells that combine to form glands. Glands are organs that secrete substances like hormones, sweat… Under the microscope, the gland is shown as a clear space in the epithelium. EPITHELIAL TISSUE Epithelial cells are tightly packed together to form barriers between the body and the external environment, and between distinct internal environments within the body. COVERING EPITHELIUM This epithelial tissue covers the outside of the body (epidermis) and lines internal cavities (mucous membranes of the digestive tract and endothelium of the blood vessels) Under the microscope, the cell usually have cubic shape with a clear nucleus. NERVOUS TISSUE Nervous tissue transmits nerve impulses. It consists of specialised branch-like cells called neurons. Neurons are protected by neuroglia cells that also provide necessary nutrients.  MUSCLE TISSUE Muscle tissue is formed by cells called myocytes that are able to contract. CARDIAC MUSCLE TISSUE It makes up the heart muscle. This tissue contracts involuntarily and quickly, and is responsible for the heartbeat. Under the microscope, the cells look striated and with one single nucleus. MUSCLE TISSUE Muscle tissue is formed by cells called myocytes that are able to contract. SKELETAL MUSCLE TISSUE It makes up the muscles that cover the skeleton. Under the microscope, the cells look striated and with MORE THAN ONE nucleus. MUSCLE TISSUE Muscle tissue is formed by cells called myocytes that are able to contract. SMOOTH MUSCLE TISSUE It is responsible for the movements of the intestines and other organs..  Under the microscope, the cells ARE NOT striated and with ONE nucleus. ORGAN SYSTEMS What do we need for living? Remember the three vital functions? - Nutrition - Interaction - Reproduction What do we need to perform the three of them? ENERGY  every cell in our body. It consists on the How do we obtain following formula: energy? Remember this process, it will be the Thanks to a process called cellular main topic during the next units. respiration. This process takes place in O2 + nutrients → CO2 + energy  To obtain energy, the main ingredients are oxygen and nutrients. Then, our cells transform them into energy. CO2 (carbon dioxide) is a waste product that must be expelled out of our body. respiration. This process takes place in How do we obtain every cell in our body. energy? Remember this process, it will be the Thanks to a process called cellular main topic during the next units. following formula: Digestive system It consists on the O2 + nutrients → CO2 + energy Respiratory system
