Read the text and answer the questions using whole sentences: Cells are the building blocks of the living world. Living things as diverse as bacteria, algae, fungi, protozoans, animals, and plants all consist of one or more cells. Cells are made up of components that help living things to eat, respire, excrete wastes, and carry all of the necessary functions of life. The components of a cell are organized to do the three functions (main functions) of living things are: 1. Nutrition: all living things have ways of taking in the substances they need to grow and survive. 2. Relation: Living things have a relationship with the environment that surrounds them. Humans use their senses (seeing, hearing, smelling, tasting, touching) to relate with the world. 3. Reproduction: all living things are born, live for a period of time and then die. a) b) c) d) e) 2. What are cells? Write the name of four different living things. What is the nutrition function? What do human use to relate with the world What is the reproduction function? Write down each cell the name of it and write the names of the differents parts 3. Tick the information about animal and plant cells Animal cell Different shapes Rigid cell wall Nucleus Chloroplasts Mitochindria Cell membrane 4.

Biodiversity is especially varied Saxifraga fiorilenta (a) in tropical forest (b) in urban areas 2. Animals, fungi and all protozoa are (a) Autotrophs (b) heterotrophs (c) prokaryotic 3. Plant cells are (a) round (b) polyhedral (c) star – shaped 4. Shells, bones and teeth contain (a) mineral salts (b) proteins (c) glucose 5. Match each word to its definition Nutrition heterotrophs reproduction zygote autotrophs interaction gamete 1. The processes which enable living things to react to changes in their enviroment. ________________ 2. These include plants, algae and some bacteria. ________________ 3. The first cell of a new living thing. ________________ 4. The processes which enable living things to obtain the energy and matter they need to live. ________________ 5. This is a sex cell. ________________ 6. These feed on organic matter which is already alaborated. ________________ 7. The processes which enable living things to create new living things. _______________ 6. Complete the table using the following words (you need to use the same word in differents boxes) Plants - 1 cell - autotroph – bacteria - Protoctist – Fungi - prokaryotic – pine tree - algae - a lot of cells – Animal – eukaryotic – mushrooms kingdom Monera Type of cells 1 or a lot cells Nutrition Example eukaryotic Heterotroph A lot horse I E S L A D e p a r t a m e n t V A L L D d e I G N B i o l o g í a i A G e o l o g i a A l u m n @ _ _ _ _ _ _ _ _ _ _ _ _ C u r s _ _ _ _ _ _ _ D a t a _ _ _ _ _ Saxifraga fiorilenta 7. Read the text and answer Biodiversty is the variety of life on Earth in all its forms. It is the result of evolution, a slow process which began with the first life forms and still coontinues today. Species change and adpat to the enviroment. Biodiversity varies tremendously throughout the worl. It is influenced by climate and habitats. Some regions have lost some of their biodiversity because plant and animal species have been severely reduced or even destroyed by deforestation, uncontrolled hunting and fishing, pollution and other factors. a) b) c) d) What does biodiversity mean? What is the name of the process which began with the first forms of life? Why does biodiversity vary throughout the world? What factors can affect and reduce biodiversity? 8. Classify the following living things according the kingdom they belong to and according the kind of nutrition they have. Paramecium - Human - meningitis bacterium – pig – chicken - orange tree - elephant – mushrrom – tetanus bacterium –– algae – butterfly – rose – pine tree – starsea Monera Protoctist Fungi Autotrophs Plant Animal Heterotrophs 9. Classify in the table the human actions which affect biodiversity Intensive agriculture introduction of foreign species uncontrolled fishing deforestation road construction urban development forest fires industrial deveolpement uncontrolled hunting Destruction of habitats Destruction of species pollution
