<strong>Grade</strong> <strong>11</strong> <strong>Life</strong> <strong>Science</strong>s Lesson PlansGRADE <strong>11</strong> SUBJECT <strong>Life</strong> <strong>Science</strong>s WEEK 4 TOPIC Biodiversity of plants Lesson 1 & 2LESSON SUMMARY FOR: DATE STARTED:LESSON OBJECTIVESDATE COMPLETED:Content: (CAPS p40)Biodiversity of plants:Grouping of bryophytes according to the presence/absence of:• Vascular tissue (xylem and phloem).• True leaves and roots.• Seeds or spores.• Fruit.The learners will be able to:• List the 4 groups of plants: Bryophytes, Pteridophytes, Gymnosperms and Angiosperms.• Define the terms: ‘true leaves’, ‘true roots’, ‘vascular tissue’, ‘seeds’ and ‘fruit’.TEACHER ACTIVITIES LEARNER ACTIVITIES TIMING RESOURCES NEEDED1.1 IntroductionDiscuss how the Bryophytes, Pteridophytes, Gymnosperms and Angiosperms are relatedto each other. Understanding <strong>Life</strong> <strong>Science</strong>s has a good flowchart. Solutions for all Fig 2.2p56 have a phylogentic tree.2.2 Main Body (Lesson presentation)Whole class discussionLearners to copy down theflow chart or phylogenetictree.15 minSolutions for all Fig 2.2 p56Understanding <strong>Life</strong> <strong>Science</strong>s Fig 1.2.1p54Learners to complete the colouring in page on the various plants.10 minHave a whole class discussion on the following:Explain what is meant by the following terms:• True leaves: The leaf tissue is differentiated into xylem and phloem.• True roots: The root tissue is differentiated into xylem and phloem.• Vascular tissue: Possess true conducting tissues i.e. xylem and phloem• Seeds: Contain and protect a plant embryo. Usually structurally modified to allow fora specific type of dispersal away from the parent plant.• Spores: a single haploid cell that eventually develops into an adult plant in fungi andBryophytes; it develops into a pro-thallus in ferns and into pollen in seed plants.• Fruit:following fertilization in flowering plants, the ovary becomes fleshy housing thedeveloping embryos in a seed /seeds. Fruits are usually produced to encourageanimals to eat them allowing for seed dispersal.Whole class teaching, followedby writing definitions innotebooks,15min• Discuss the concept of alternation of generations and have learners draw a flowchart representing this.Term 1 Page 26© Gauteng Department of Education (CAPS version)
