Biology: 1. Living Things Please remember to photocopy 4 pages onto one sheet by going A3>A4 and using back to back on the photocopier Syllabus OB38 Understand how to use a simple key to identify plants and animals, including vertebrates and invertebrates OB39 Investigate the variety of living things by direct observation of animals and plants in their environment; classify living organisms as plants or animals, and animals as vertebrates or invertebrates OB40 Identify the basic life processes and characteristics common to all living organisms: nutrition, respiration, excretion, growth, reproduction, movement and response

OB41 Recall that living things are composed of cells, tissues, organs and systems, and understand that growth results from cell division Biology is the study of living things (called organisms) Biology is the study of living things (called organisms) Student Notes The living things which we are most familiar with are plants and animals. Plants| Animals| Make their own food| Do not make their own food| Do not move from place to place| Move from place to place| Have cell walls| Do not have cell walls| Animals can then be sorted into two groups: 1. Vertebrates = Animals that have a backbone.

Mammal, fish, bird, reptile, amphibian). 2. Invertebrates = Animals that do not have a backbone. (Spiders, worms, jellyfish, anemones, etc). Biology Keys A key in Biology is a set of instructions which help us to identify or classify an organism. The key on the right helps us to identify classify different types of vertebrates. Can you identify where humans fit into this map? Basic life processes and characteristics common to all living organisms All living things have 7 life processes or characteristics in common. These are: 1. Growth All living things can grow/increase in size.

This happens through cell division where cells have the ability to make copies of themselves. 2. Movement All living things can move. Animals can walk, fly etc, plants move their parts. 3. Nutrition All living things must be able to take in material from their environment such as food, which is needed to produce energy. 4. Respiration All organisms must extract energy from the food that they consume. Aerobic respiration uses oxygen to obtain energy from food. 5. Excretion Getting rid of waste products from chemical reactions in the body. 6. Response Reacting to a stimuli or changes in the environment. 7. Reproduction

The formation of new individuals. Organisms must be able to reproduce themselves or their species will become extinct. Cells, Tissues, Organs and Systems All organisms are composed of cells which form tissues which form organs which in turn form systems. All organisms are composed of cells which form tissues which form organs which in turn form systems. Cells>Tissues>Organs>Systems Cells Cells are the main building blocks of life, e. g. blood cells and skin cells. (We will look at them in detail in the next chapter). Tissues A tissue is made up of a group of similar cells which carry out the same function, e. . skin tissue and muscle tissue. Organs An organ is made up of different types of tissue working together, e. g. the heart and the lung. Systems A system is formed by a group of organs working together, e. g. the reproductive system and the digestive system.

“It’s extraordinary that so much time is spent educating people about birth and sex, but so little about this equally profound thing [death] that happens to everyone.

[2008 OL] Letter| Key feature of organism| A| Four pairs of legs| B| Segmented body, no legs| C| Three pairs of legs| D| Eight to ten pairs of legs| The table shows a simple key used to identify some common organisms found in a habitat. In the case of any two of the organisms shown on the right, write the letter corresponding to a key feature given in the table above beside the organism which that best describes.

(ii) Write the letter O beside the name of a body organ in the table on the right. Exam Solutions 1.

What is an organ made up of? 3. Define (i) sensitivity, (ii) reproduction, (iii) respiration and (iv) excretion. 4. Explain the term tissue. 5. What process do cells undergo to allow growth in organisms? 6. When discussing ‘Living Things’, why are so few people prepared to discuss ‘Death’? Is death natural or unnatural? How do most animals in ‘nature’ die? If another animal attacked a koala bear who would like to see win the fight? Why?
