Organisation of cells - Study guides, Revision notes & Summaries

AnatomyC correct answers Study of body structures Gross anatomy correct answers Study of large body structures visible to the eye—e.g. heart, lungs. Microscopic anatomy correct answers Study of structures too small to be seen by the eye and instead are viewed using a microscope. Physiology correct answers Study of body functions and relates to the operation of specific organ systems. Structural level of organisation correct answers Chemical Cells Tissues Organs Organ sy...

2.1 describe the levels of organisation in organisms: organelles, cells, tissues, organs and systems ~~> Tissues are a collection of similar cells all serving a common function. Organs are made up of several kinds of tissues together forming a functioning unit. Systems are several organs forming an organ system. Like the cardiovascular system is made up of the heart, blood and blood vessels. 2.2 describe cell structures, including the nucleus, cytoplasm, cell membrane, cell ...

Levels of structural complexity Learning outcome After studying this section you should be able to: describe the levels of structural complexity within the body. Within the body are different levels of structural organisation and complexity. The most fundamental level is chemical. Atoms combine to form molecules, of which there are a vast range in the body. The structures, properties and functions of important biological molecules are considered in Chapter 2. Cells are the smallest indep...

1 Know the levels of organisation within the human body Ultrastructure of an animal cell: plasma membrane; cytoplasm; nucleus; nucleolus; endoplasmic reticulum; golgi apparatus; vesicles; lysosomes; ribosomes; mitochondria; centrioles Tissue types: epithelial (glandular, lining, covering), eg salivary gland of digestive tract, endothelial lining of arteries and veins in the cardiovascular system, epithelial lining of lung tissue in the respiratory system; muscular, eg smooth muscle surro...

Cell theory - Answer States that new cells are formed from existing cells and that the cell is a fundamental unit of structure, function and organisation in all living organisms. it is considered a unifying concept in biology Cells, tissues and organs - Answer In complex organisms, cell are organised into tissues, tissues into organs, organs into systems e.g. animal↓ muscle cell → muscle → heart → circulatory system specialised cell → tissue → organ → system xylem vesse...

TESTBANK FOR THE HUMANBODY: PRINCIPLES OF ANATOMY AND PHYSIOLOGY COMPLETE SET SUMMARY | LATEST UPDATE Chapter 1 – An introduction to the human body 1.1 Anatomy and physiology defined Define anatomy and physiology, and name severalsubspecialties of these sciences - Anatomy is the science of body structures and the relationships among them - Physiology is the science of body functions – how the body parts work 1.2 Levels of structural organisation and body systems Describe the bo...

fimbriae/pili, afimbrial adhesins correct answers mechanisms of adhesion to host surfaces adhesins at tip that bind to specific glycoproteins/glycolipids on host cell membranes, long major filament that can extend beyond the capsule correct answers main features of pili/fimbriae molecules embedded in bacterial membranes, bind to glycoproteins or glycolipids on host membranes or can bind ECM such as fibronectin correct answers main features of afimbrial adhesins tracheal colonization fac...

BIOL 266 DETAILED FINAL NOTES| CONCORDIA UNIVERSITY|UPDATED 2024/2025 UNIT 9.0 – THE CYTOSKELETON Two functions of the cytoskeleton: 1. Provides structural framework for the cell,serving as a scaffold that determines cell shape and the general organisation of the cytoplasm. 2. Responsible for the movements of the entire cells and for the internal transport of organelles and other structures (such as mitotic chromosomes) through the cytoplasm. The cytoskeleton is composed of 3 principa...

GCSE Biology AQA (Organisation) Graded A Specialised cells As an organism develops, cells differentiate to form different types of cells. As a cell differentiates: - it may change shape - different sub-cellular structures develop to let it to carry out a specific function. Include cells such as sperm, nerve and muscle cells. Sperm cell Tail: to propel the sperm to fertilise the egg. Mitochondria: sperm have many of these cell components, which are the major site of respiration, to ...
