Classification Classification Classification is a system of organizing things based on similarities and differences

Classification of things into two categories THINGS NON LIVING

There are seven essential life processes. To remember these processes meet our little blue woman MS. R. NERG What do all the letters in her name stand for? 7A Signs of life The meaning of life How do we identify living from non living?

7A Signs of life - The meaning of life S = SENSITIVITY Living things notice and react to changes in their surroundings. They can respond to light, heat, sound, taste, sight or touch. R = RESPIRATION Living things need energy to carry out the functions that keep them alive. M = MOVEMENT Living things are able to move about. Animals move from place to place. Plants move by responding to light.

7A Signs of life - The meaning of life R = REPRODUCTION Living things produce offspring. G = GROWTH Living things grow, increasing in size and complexity. N = NUTRITION Living things need to take in food. E = EXCRETION Living things have to get rid of unwanted waste products.

All living things are classified into five main groups called kingdoms. Most living things belong to the animal kingdom or the plant kingdom. The Classification Living Things plants Protoctists animals Bacteria (prokaryotes) fungi living things

CLASSIFYING ANIMALS Animals Vertebrates (possess a backbone) BirdsFish Amphibians Reptilesmammals Invertebrates (no backbone) Worm-like Not worm- like Has jointed legs

Animals Vertebrates Mammals Fish Reptiles Amphibians Birds Invertebrates Flatworms True worms Molluscs Echinoderms Cnidarians Arthropods

Vertebrates These are animals with a backbone.

Vertebrates Mammals Have body hair or fur Have mammary glands that produce milk Warm blooded

Vertebrates Fish Live in water Breathe with gills Streamlined bodies Have cartilage or bony skeleton Cold blooded Mostly lay eggs

Vertebrates Reptiles Have dry, scaly skins Egg laying Breathe with lungs Cold blooded

Vertebrates Amphibians Moist skin Lay their eggs in water Larvae have gills and live in water Adults have lungs and live on land Cold blooded

Vertebrates Birds Have feathers and wings Lay eggs with hard shells Breathe with lungs Warm blooded

Invertebrates These are animals without a backbone

Invertebrates Cnidarians Hollow bodied Mouth is the only body opening and is surrounded by tentacles Uses sting cells to paralyse prey

Invertebrates Flatworms Flat thin bodies Digestive system has only one opening Animals are both male and females Mostly parasites

Invertebrates True Worms Rounded bodied Bodies made of segments

Invertebrates Molluscs Not segmented Body in three continuous parts with head, body and foot Have one or two shells

Invertebrates Echinoderms Spiny skinned Body in five parts Central mouth with respiratory gills

Invertebrates Arthropods Hard exo-sekeleton on outside of body Has eyes and mouth Body divided into more than one segment CrustaceansArachnidsInsects Centipedes & Millipedes

Quiz 1] Animals with a backbone are called ____ 2] Animals that can live on land and in water ____ 3] ____ have wings and can fly. 4]Butterfly is an example of an ______ 5] ______ have shells 6]____ is sorting organisms into groups. 7]Living things are called ____ 8] A animal which cant control its internal body temperature is ________ _________ 9] ________ have body divided into five parts. 10] The basic unit of classification is ______.

CLASSIFYING PLANTS Plants Flowering plants Non- flowering plants ConifersFernsMosses

Plant Classification Plants are living organisms that cannot move around. Most plants make their own food through photosynthesis. Vascular Tissues are similar to animals blood vessels. In plants they are called xylem and phloem, they transport nutrients and water to cells in the plant. Seeds contain a baby plant (embryonic plant) the outer covering provides safety and nutrients to the seedling. Spores are a small single celled reproductive structure normally spread by non-flowering plants like fungi.

Mosses: They have simple leaves and shallow roots, with no proper vascular systems. The leaves are very small and are not covered with a waterproof, waxy cuticle layer. Mosses, Angiosperm and Lichen are often found in damp areas as they dry out easily. They reproduce using spores. Ferns: They have proper roots and stems, and leaf-like fronds. The leaves are not covered in a waterproof, waxy cuticle layer and so they dry out easily and are generally found in damp places. They do have a vascular system. They reproduce using spores. Conifers: They have vascular tissues. They are large plants with proper roots and stems and needle-shaped leaves with a waxy cuticle. They are good at surviving in dry or cold climates. They reproduce using seeds found in cones. Flowering Plants: They have vascular tissues. They have proper roots and stems and have flowers. Their leaves are large and flat and have a waxy cuticle. They reproduce using seeds found in fruits. Plant classification

What is Non-Living things? Non-Livings cannot reproduce Non-Livings cannot move by itself Non-Livings cannot grow Non-Livings cannot die Non-Livings do not need food,water and air Unable to respond to stimuli Do not get rid of waste

Classification of Elements in the periodic table The elements in the periodic table are classified into groups and periods because of the way they look and act.

Dichotomous key

. we will try a simple sorting activity to organize some dogs into groups according to their similarities... Constructing a key

Divide the dogs into two groups Group AGroup B We divide the dogs into groups by asking a question to which there is a yes or no answer... Is the dog large (above 65cm)?

Large DogsSmall Dogs We can now divide each group down into further sub divisions...

white and grey coatsbrown and black coats What question could be used to divide the large dogs down into further groups? Does the dog have a brown and black coat? No Yes

Finally the groups can be divided down into individual dogs to which we can then give the names. What question has been used to separate these two dogs? Does the dog have curly hair? Airedale TerrierRotweiller yes no

1. Is the dog over 65cm tall? If yes go to question 2 If no go to question 5 2. Does the dog have a brown and black coat? If yes go to question 3 If no go to question 4 3. Does the dog have a wooly coat? Yes Airedale Terrier NoRotweiller By asking questions that divide the dogs we can produce a key

Does the tail curl upwards? Question 4 Yes No Akita Old English sheepdog

Now complete the key, starting with question 5, for the small dogs. You can make your own questions up.

Does the dog have a snub nose? YesNo Question 5 Go to question 6Go to question 7

Does the dog have long hair? Question 6 YesNo Pekinese Bulldog

Question 7 Does the dog have very long ears? Yes No Basset hound Dachsund
