  1. SCIENCE 5 Topic 2: Theplantkingdom

  2. Pupil’sbook Summary

  3. p. 20 What are thecharacteristics of plants? • Plantsmaketheirownfood. • Plantscan’tmovefrom place to place. • Mostplants reproduce byseeds, whichdevelopsfromflowers. • Plantscontainchlorophyll.

  4. Photosynthesis

  5. Pupil’sbook Exercisecorrection

  6. p. 19 ex 1 Theclassification of plants

  7. p. 20 ex 3 Plantcells • Plantcellscontain a nucleus, a strongcellwall, whichgivesthecellitsshape, a cellmembrane and cytoplasm. Theycontainchloroplasts, whichgiveplantstheirgreencolour and are used in photosynthesis. Finally, plantcellshave a largevacuole. Thiscontrainswater and minerals.

  8. p. 20 ex 4 Parts of a cell

  9. p. 21 ex 2 Label a plant

  10. p. 21 ex 3 Parts of a plant • Mostplantshaveroots, stems and leaves. • Rootsabsorbwater and mineralsneededfornutrition.

  11. p. 22 ex 1What do plantsneedtoperformphotosynthesis? In ordertoperformphotosynthesis, plantsneed: • Water (takenfromthesoil) • Minerals (takenfromthesoil) • Carbondioxide (takenfromthe air) • Sunlight (fromtheSun) • Chlorophyll (fromthechloroplasts, in theplantcells)

  18. p. 28 ex 3 Photosynthesis Water + minerals + carbondioxide + sunlight + chlorophyll= glucose and oxygen

  19. P. 28 ex 4 Plantreproduction

  20. p. 28 ex 5 Plantclassification • Ferns reproduce usingspores. • Angiospermshaveflowers and seeds. • Algaedonthaveroots, stems, leaves and flowers. • Gymnospermsmakeseeds in cones. • Mosseshavevery simple roots, stems and leaves. • Themysterywordis: SOIL

  21. p. 29 ex 6 Identifythekeywords Allplants share someimportantcharacteristics. Firtly, plants are producers, whichmeansthey can maketheirownfood. Secondly, allplantsinteractwiththeirenvironment. They can reacttolight, temperature and water. Thirdly, almostallplants are greenbecausetheircellscontainchlrophyll. Finally, allplantsreproduce. Someplants reproduce bygrowingflowerswhichthen produce seeds. Thisiscalledsexual reproduction. Otherplants use asexual reproduction.

  24. p. 7 ex 1 Writedescriptions of theplants in thephotos. • A) Thisisanangiosperm. It has roots, a stem, leaves and flowers. It produces seeds and fruittoo. • B) Thisis a fern. It has roots, a stemand leaves. Itdoesn’thaveflowers. Itdoesn’t produce seedsorfruit. • C) Thisis a moss. It has very simple roots, a stem and thinleaves. Itdoesn’thaveflowers. Itdoesn’t produce seedsorfruit. • D) Thisis a gymnosperm. It has roots, a stem, leaves and flowers. Itdoesn’t produce anyfruit. Theseedsdevelop in cones. • E) Thisisanalgae. Itdoesn’thave true roots, stems, leavesorflowers. Itdoesn’t produce seedsorfruits.

  25. P. 7 ex 2 – Readthedefinitions and writethewords. • Cone : thisiswherethegymnosperm’sseedsdevelop. • Fronds: These are large, longleaveon a fern.

  33. p. 10 ex 11 Sexual reproduction in plants • Mostfloweringplants use sexual reproduction. Theflowershavebothmale and femaleorgans. Themaleorgans are calledstamens. Eachone has a longfilament and ananther at theend. Thisiswheretheplant produces pollen. Thefemaleorganis in the centre of theflower and iscalledthepistil.
