Page 2 of 3,Where Does It Come From,Think about the things you use every day Just. like any other organism you depend on the,environment to meet your needs The food you. eat comes from plants and animals,Also much of what you use is. made of materials processed,from living matter,Observe and Think Identify. three nonfood items you come,into contact with every day.
Where does the material for,these products come from. How Can a Multicellular,Organism Reproduce on,Take an old potato and cut it in half making. sure that there are eyes on both halves,Plant each half in a pot of soil. Water the pots once a day,After two weeks remove the. potato halves from the pots,and examine,Observe and Think.

These three kingdoms are made up almost entirely of multicellular. organisms The cells in multicellular organisms are organized in ways. that enable them to survive and reproduce, Chapter 10 Introduction to Multicellular Organisms 333. Page 2 of 7,Specialization,Specialization, What are some advantages of specialization SKILL FOCUS. Making Models, 1 Form into two teams each representing an organism The single celled team MATERIALS. will be made up of just one person the multicellular team will be made up of two boxes each. containing, three Each team obtains a box of materials from the teacher. 20 paper clips, 2 Each team must do the following tasks as quickly as possible make a paper 2 pieces of.
clip chain write the alphabet on both sides of one piece of paper and make paper and. a paper airplane from the second piece of paper The members of the. three person team must specialize each person doing one task only TIME. 10 minutes,WHAT DO YOU THINK, What are some advantages to having each person on the. three person team specialize in doing a different job. Why might efficiency be a factor in the activities done by cells. in a multicellular organism, CHALLENGE Suppose the life of the multicellular team. depended on the ability of one person to make a paper. airplane How would specialization be a disadvantage. if that person were not at school,Levels of Organization. For any multicellular organism to survive different cells must work. together The right type of cell must be in the right place to do the. work that needs to be done, Organization starts with the cell Cells in multicellular organisms are. specialized for a specific function In animals skin cells provide protec. tion nerve cells carry signals and muscle cells produce movement Cells. of the same type are organized into tissue a group of cells that work. together For example what you think of as muscle is muscle tissue. made up of many muscle cells, VOCABULARY A structure that is made up of different tissues is called an.
Remember to add a four organ Organs have particular functions The heart is an organ that. square for tissue and organ, to your notebook functions as a pump It has muscle tissue which pumps the blood. and nerve tissue which signals when to pump Different organs that. work together and have a common function are called an organ sys. tem A heart and blood vessels are different organs that are both part. of a circulatory system These organs work together to deliver blood. to all parts of a body Together cells tissues organs and organ sys. tems form an organism,334 Unit 3 Diversity of Living Things. Page 3 of 7,Organ Systems and the Organism, In almost all multicellular organisms different organ systems take reminder. care of specific needs Here are a few examples of organ systems A system is a group of. found in many animals objects that interact,sharing energy and matter. nervous system enables a response to changing conditions. muscular system produces movement and supplies heat. respiratory system takes in oxygen and releases carbon dioxide. circulatory system delivers oxygen and removes carbon dioxide. digestive system breaks down food into a usable form. Organ systems allow multicellular organisms to obtain large. amounts of energy process large amounts of materials respond to. changes in the environment and reproduce, Check Your Reading How are the functions of organ systems related to the needs of Content Preview.
an organism Give an example,These same levels of organi. zation in living things also, Different organ systems work together For example the respiratory occur in humans as you will. learn in grade 7, system works with the circulatory system to deliver oxygen and remove. carbon dioxide When an animal such as a turtle breathes in oxygen is. brought into the lungs Blood from the circulatory system picks up the. oxygen and the heart pumps the oxygen rich blood out to the cells of. the body As oxygen is delivered waste carbon dioxide is picked up. The blood is pumped back to the lungs The carbon dioxide is released. when the turtle breathes out More oxygen is picked up when the turtle. breathes in,Organ Systems,Organ systems work together to. Blood vessels called Each lung fills with, meet the needs of an organism veins return oxygen air containing oxygen.
poor blood to the lungs,Blood vessels called The heart pumps. arteries carry oxygen blood to the lungs,rich blood to the body. Chapter 10 Introduction to Multicellular Organisms 335. Page 4 of 7,Multicellular organisms are adapted to live. in different environments, reading tip All organisms have characteristics that allow them to survive in their. Offspring is a word used to environment An adaptation is any inherited characteristic that. describe the new organisms increases the chance of an organism s surviving and producing off. produced by reproduction in, any organism Think of it as spring that also reproduce An adaptation may have to do with the.
meaning to spring off way an organism gets its energy or processes materials An adaptation. may relate to the shape or structure of an organism s body An adapta. tion can even be a form of behavior, Single celled organisms reproduce through asexual reproduction. Asexual reproduction requires only one parent and produces offspring. that are identical to the parent However when most multicellular. organisms reproduce the offspring are not exact copies of the parents. There are differences If a particular difference gives an organism an. advantage over other members in its group then that difference is. referred to as an adaptation Over time the organism and its offspring. do better and reproduce more, You are probably familiar with the furry animal called a fox. Different species of fox have different adaptations that enable them to. survive in different environments Here are three examples. Fennec The fennec is a desert fox Its large ears are an adapta. tion that helps the fox keep cool in the hot desert As blood flows. through the vessels in each ear heat is released Another adapta. tion is the color of its fur which blends in with the desert sand. Arctic fox The Arctic fox lives in the cold north Its small ears. legs and nose are adaptations that reduce the loss of heat from. its body Its bluish gray summer fur is replaced by a thick coat of. white fur as winter approaches Its winter coat keeps the fox. warm and enables it to blend in with the snow, Red fox The red fox is found in grasslands and woodlands Its. ears aren t as large as those of the fennec or as small as those of. the Arctic fox Its body fur is reddish brown tipped in white and. black coloring that helps it blend into its environment. The diversity of life on Earth is due to the wide range of adapta. tions that have occurred in different species An elephant has a trunk. for grasping and sensing A female kangaroo carries its young in a. pouch The largest flower in the world the rafflesia flower is almost a. INFER The strong odor meter wide blooms for just a few days and smells like rotting meat. of the rafflesia flower, attracts flies into the Adaptations are the result of differences that can occur in genetic. plant How might this,adaptation benefit, material The way multicellular organisms reproduce allows for a mix.
the plant ing of genetic material You will read about that next. 336 Unit 3 Diversity of Living Things,Page 5 of 7,Adaptations in Different Environments. large ears,Habitat warm Sahara light brown fur,Desert and Saudi. Size about 40 cm 15 in,1 25 kg 2 7 lb,Arctic Fox,Habitat cold Northern small ears thick white fur. Eurasia and North,Size about 50 cm 20 in,summer thin bluish gray fur. Red Fox moderate size,reddish brown fur,Habitat moderate North.
and Central America,Size about 65 cm 25 in,6 kg 13 lb. Foxes are hunters that feed on small animals How might the coat color of each. fox contribute to its survival, Chapter 10 Introduction to Multicellular Organisms 337. Page 6 of 7,Sexual reproduction leads to diversity. Most multicellular organisms reproduce sexually In. sexual reproduction the genetic material of two parents comes. together and the resulting offspring have genetic material from both. Sexual reproduction leads to diversity because the DNA in the off. spring is different from the DNA in the parents, Two different cellular processes are involved in sexual reproduc.
