IGCSE Biology (O610) Workbook Chapter 1 Characteristics and classification of living organisms The stuff you need to know in this chapter: 1.1 CHARACTERISTICS LIVING THINGS Core: Describe the characteristics of living organisms by defining the terms movement, respiration, sensitivity, growth, reproduction, excretion, nutrition Extended: Define the terms movement, respiration, sensitivity, growth, excretion and nutrition – supplement 1.2 CONCEPT AND USE OF A CLASSIFICATION SYSTEM Core: State that organisms can be classified into groups by the features that they share Define species as a group of organisms that can reproduce to produce fertile offspring Define and describe the binomial system of naming species as an internationally agreed system in which the scientific name of an organism in made up of two parts showing the genus and species Extended: Explain that classification systems aim to reflect evolutionary relationships Explain that classification is traditionally based on studies of morphology and anatomy Explain that the sequence of bases in DNA and of amino acids in proteins are used as a more accurate means of classification Explain that organisms which share a more recent ancestor (are more closely related) have base sequences of DNA that are more similar than those that share only a distant ancestor © A.

Arthropods – myriapods, insects, arachnids, crustaceans Extended: List the features in the cells of all living organisms limited to ribosomes for protein synthesis and enzymes involved in respiration List the main features used to place all organisms into one of the five kingdoms: animal, plant, fungus, prokaryote, protoctist List the main features used to place organisms into groups within the plant kingdom, limited to ferns and flowering plants (dicotyledons and monocotyledons) List the features of viruses, limited to protein coat and genetic material 1.4 DICHOTOMOUS KEYS Core: Construct and use simple dichotomous keys based on easily identifiable features © A.

Complete the table to list the seven processes that all living organisms carry out. For each process, give an example of each for the two different organisms: Life Process Definition Movement Respiration Sensitivity Growth Reproduction Excretion Nutrition © A. Nixon 2016 For videos, worksheets and other resources go to ScienceSauceOnline.com 3 IGCSE Biology (O610) Workbook 2. Give an example of how the organisms carry out these processes. Some of them have been done for you. Life Process Tiger Apple tree Movement ∑ Respiration Uses hormones to sense Sensitivity direction of gravity so roots grow downwards. Growth Uses sexual reproduction Reproduction to produce offspring known as “cubs”. Excretion Nutrition © A.

List the five kingdoms of life i) ____________________ ii) ____________________ iii) ____________________ iv) ____________________ v) ____________________ 3. Look at the table below and complete the blanks. You should be able to figure out most of the answers based on information that is already in the table Coconut Palm Black-backed Common Rank Human Gray Wolf Tree jackal chimpanzee Domain Eukarya Eukarya Kingdom Animals Phylum Chordata Cycadophyta Class Mammalia Mammalia Cycadopsida Mammalia Order Primates Carnivora Arecales Carnivora Family Homonidae Canidae Arecaceae Canidae Genus Homo Canis Cocos Pan Species sapien lupus nucifera mesomelas troglodytes 4. Which two parts of the ranking system are used to give an organism’s binomial name? © A. Nixon 2016 For videos, worksheets and other resources go to ScienceSauceOnline.com 5 IGCSE Biology (O610) Workbook 5. Give the binomial names for each of the species mentioned in the ranking table above: Human: _______________________ Coconut palm: _______________________ Common chimpanzee: _______________________ Grey wolf: _______________________ Black-backed jackal: _______________________ 6(A). We classify organisms based which other organisms they are related to. For example, chimpanzees are quite closely related to humans, and lizards are related to geckos. This is because they share the same ancestors. Look at the picture the rock hyrax (sometimes called a “dassie”). Put a circle around the organisms that you think might be closely related to it, and put a box around the organisms that you think are least closely related to it: elephant rabbit lizard rat mouse © A.

Of all the animals on that list, the dassie is most closely related to the: ______________ (Ask your teacher) We can’t just group animals together based on how they look. Using the dassie as an example, explain why using anatomy and morphology alone for classification can be a problem: 7. Explain why using DNA is a better way to classify organisms: © A.
