KS3 Science Revision Worksheets Special Edition P Hill Beaver Educational Resources 2000 Registered to Hampton Community College TW12 3HB. W S 1 Life processes Name, All plants and animals carry out seven processes in order to stay alive The table. below shows these seven LIFE PROCESSES, Movement This is easier to see in animals than in plants Plants move very slowly as. Respiration Getting energy by reacting food with oxygen. Sensitivity Sensing changes around them and then responding. Growth Food is used to build up the parts of the body. Reproduction Producing offspring young, Excretion Getting rid of poisonous waste chemicals from the body. Nutrition Plants make their own food by PHOTOSYNTHESIS Animals must feed. on plants or other animals, Use the name MRS GREN as an easy way to remember all 7 life processes.
Exercise 1 Complete the sentences below,1 It is usually easier to see movement in A. 2 We respire in order to produce E for the body,3 Our ears eyes and nose give us S. 4 If living organisms did not R they would soon become. extinct die out,5 The kidneys E a waste chemical called urea. Exercise 2 A motor car moves but it is not living Complete the two lists below to show. which processes it does and does not show, Processes a car does show Processes a car does not show. movement growth,nutrition takes in petrol, KS3 Science Revision Worksheets Special Edition P Hill Beaver Educational Resources 2000 Registered to Hampton Community College TW12 3HB.
W S 2 Plant and animal organs Name, Exercise 1 Fill in the missing words in the passage below. In the human body many cells of the same join together to. form TISSUES These tissues then join together to form An. organ is a part of the that has one or more important. to carry out All of the organs work together to keep the. body The bodies of most animals and are made up, of many organs Several organs working together on one large task is. called a For example in the human body the mouth gullet. stomach and make up the digestive system, intestines type organs plants jobs body healthy system. Exercise 2 Join up the organs below to their correct description. Descriptions,Brain This pumps blood around the body. Heart This organ makes food in a plant,Leaf This controls the rest of the body.
Stomach This organ makes seeds in a plant,Flower This helps to digest food. KS3 Science Revision Worksheets Special Edition P Hill Beaver Educational Resources 2000 Registered to Hampton Community College TW12 3HB. W S 3 Animal and plant cells Name, Exercise 1 Fill in the missing words in the passage below. The bodies of all plants and are made up of tiny living units. called Some microscopic organisms consist of only a. cell but the bodies of most plants and animals are made up of. of cells There are many different of plant and animal cells. The diagrams below show the that they usually contain. parts animals cells types millions single,Plant cell. Animal cell,cell membrane,chloroplast, Exercise 2 Join up the cell parts below to their correct jobs. Cell part Job, Nucleus covers the membrane and gives strength to a plant cell.
Cytoplasm controls what the cell does, Cell wall jelly that fills the cell chemical reactions happen here. Chloroplast stores water in a plant cell, Vacuole absorbs light energy to make food for the plant. KS3 Science Revision Worksheets Special Edition P Hill Beaver Educational Resources 2000 Registered to Hampton Community College TW12 3HB. W S 4 Different cells for different jobs Name, Exercise 1 Fill in the missing words in the passage below. Nearly all cells contain a membrane and cytoplasm There are. many types of cells They vary in their shape and, depending on their functions jobs Each type of cell is well. suited to its function In the human there are about twenty. different types of cell each has a certain to do This makes the. body work much than if each cell was trying to do everything. better different nucleus size body adapted job, Exercise 2 Join up the cells below to their correct descriptions.
Ciliated cell,This cell is found lining the windpipe. Its surface is covered with tiny hairs,called cilia These waft dirt and germs. up to the throat,Palisade cell,This cell is found on the top side of a. leaf It contains tiny green discs called,chloroplasts These absorb sunlight in. order to make food,Sperm cell,It uses its tail to swim to the ovum.
The head contains the nucleus which,enters the ovum during fertilisation. Root Hair cell,This is found on the surface of a root. Its job is to absorb water from the,soil It is long and thin with a big. surface area to absorb water, KS3 Science Revision Worksheets Special Edition P Hill Beaver Educational Resources 2000 Registered to Hampton Community College TW12 3HB. W S 5 A balanced diet Name, Exercise 1 Fill in the missing words in the passage below.
In order to stay the body needs seven main chemicals which. are called food These are carbohydrates proteins, minerals vitamins fibre and water A balanced diet contains the. amounts of all seven food types Carbohydrates are sugars. and Carbohydrates give us energy quickly Fats also give us. but they release it much more slowly Stored fat under the. skin also helps us to keep We need to help us grow. and to repair damaged parts Minerals and are needed in. smaller amounts to keep the body healthy Fibre helps to keep the food. moving along the, intestines types fats warm correct protein starch healthy energy vitamins. Food type Foods rich in this, Carbohydrate Starchy and sugary foods e g potato bread cereals and cakes. Protein Meat fish eggs cheese milk and nuts, Fat Vegetable oils butter lard cream cheese and some meats. Vitamins Fresh fruit and vegetables, Minerals A wide range of foods e g iron from meat and calcium from milk.
Fibre Cereals fruit and vegetables, Exercise 2 Write down the main FOOD TYPES that each of the foods below contain. KS3 Science Revision Worksheets Special Edition P Hill Beaver Educational Resources 2000 Registered to Hampton Community College TW12 3HB. W S 6 Food and digestion Name, Exercise 1 Fill in the missing words in the passage below. The body needs food for a number of reasons We need food for growth. and to worn out or damaged parts We also get, from food Energy is used for movement producing and to keep. all of the parts working properly Before the body can use the. food we eat it must pass into the blood The food is broken down into. very small soluble molecules by the system These molecules. then pass through the walls of the and into the blood. intestines heat repair cells digestive energy, Exercise 2 Study the diagram below of the human digestive system and then carefully. add the labels by choosing from the list at the bottom of this page. tongue salivary gland liver gall bladder small intestine gullet. pancreas stomach large intestine appendix rectum anus. KS3 Science Revision Worksheets Special Edition P Hill Beaver Educational Resources 2000 Registered to Hampton Community College TW12 3HB. W S 7 Stages of digestion Name, Food is slowly broken down by our digestive system It is broken up by chewing in the.
mouth and by churning of the stomach muscles Special chemicals called ENZYMES. break up large food molecules into smaller ones These molecules then slowly seep out. into the blood through tiny pores in the walls of the small intestines Any undigested. food enters the large intestine where water is absorbed back into the blood The. solid waste is then passed out of the body,What to do. This table gives descriptions of organs in the human digestive system Read each description and then. write down the name of each organ in the left hand column Use the words at the bottom of this page. Organ Description, Here the food is chewed and moistened with saliva The food is shaped. into a round ball before it is swallowed, This is a tube that squeezes the food down to the stomach. This is a bag that churns up the food It contains gastric juice and. hydrochloric acid Gastric juice contains an enzyme that digests protein. The acid kills germs, This is a very long tube that the food passes into after it leaves the. stomach Here the food is completely digested and then it is absorbed. through the walls and into the blood stream, This is a small leaf shaped organ It makes pancreatic juice which passes.
into the small intestine This juice contains an alkali that helps to. neutralise the acid from the stomach It also contains several enzymes. This organ makes a chemical called BILE which is stored in a small bag. called the GALL BLADDER The bile is squeezed into the small intestine. where it helps to break up large pieces of fat, This is a wide tube that the undigested food passes through Water is. absorbed from this back into the body, This organ has no function in humans but it helps with digestion of plant. material in herbivores such as sheep It sometimes becomes infected in. humans and then it must be removed, The dried out waste food material is stored here until it is ready to be.
