Year 10 Science Study Guide Producers The plant way of life Introduction to this unit This unit is important because: Understanding the plant way of life is very important to us. Consumers, like us, ultimately rely on producers (plants) for our food. How do plants grow? What adaptations do they have that keeps them alive? By answering these questions we can have better control of our supply of food. New Zealand Curriculum Objective(s) This unit is based on Level 5 of the New Zealand Curriculum in Science. Life processes Identify the key structural features and functions involved in the life processes in animals and plants. Ecology Investigate the interdependence of living things (including humans) in an ecosystem. Key competencies Thinking Are you able to understand the Te Whare Tapa Wha Model? Using language, symbols & text Can you label the parts of a flower? Managing self Have you completed assignments on time? Do you bring the correct equipment to class? Relating to others Did you work well with others and listen to their ideas when doing group work? Participating and contributing Did you get involved when carrying out practicals and suggest ideas during class discussions? Page 1 of 4 Specific Learning Outcomes At the end of this unit… Support …all students should be able to… Describe some common uses of plants. Label the parts of a typical flower and relate to ‘male’ and ‘female’. Describe the process of pollination. Describe a seed as the result of sexual reproduction in plants and that a plant grows from a seed. Describe that a plant makes food using materials from the air, soil and energy from the sun. Label the basic parts of a plant (roots, stem, stalk, leaf). Demonstrate knowledge that water and minerals required by plants enter through the roots. Core …most students should be able to… Explain the importance of plants to all life. List the common uses of New Zealand native plants for Maori medicinal purposes and relate this to the Maori model of health (Te Whare Tapa Wha) Plant Reproduction Describe the parts of a flower and their related functions. Define and distinguish pollination and fertilisation. Describe the main ways a flower gets pollinated (by wind or insects). Describe the advantages and disadvantages of insect- and wind-pollinated flowers. Describe the development from zygote to seed to a full plant i.e. fertilisation to germination to growth. Describe the requirements for a seed to germinate. Describe the parts and functions of a seed and relate to the embryo plant. Explain the importance of seed dispersal. Explain the structural difference in insect- and wind- pollinated flowers Discuss the adaptive features for seed dispersal in plants Page 2 of 4 Plant processes Describe the movement of water through plants, in terms of osmosis and transpiration. Describe the process of photosynthesis in simple terms of its requirements (water, carbon dioxide and chlorophyll) and products (glucose, oxygen). Describe the respiration of plants. Explain the structure and function of parts of a typical leaf. Explain the essential role plants play in the carbon cycle and relate this to the greenhouse effect and theories of global warming. Investigations Plan and carry out investigations into the production of starch in plants under different conditions. Extension … some students will progress further and should be able to… Explain the movement of water through plants, in terms of osmosis and transpiration.
