Transcript: Trees, Plants & Shrubs Importance of Plants Why are plants Important? Ecosystem Ecosystem Biomes A biome is an extensive ecological unit, largely defined by climate, representing major life zones of large natural areas. In south Africa there are 9 biomes. Each biome has a characteristic set of plant species, typified by overall physiognomy and animal species. Biomes Guiding and Plants Guiding - Predicting animal movements - Symbiosis - Education - Aesthetic Strangler fig Definition What is a PLANT? An autotrophic organism that contains chlorophill and is able to produce it's own food from organic material through photosynthesis and is non-mobile Definition Definition Plant Kingdom [taxonomy] Plant Kingdom THALLOPHYTES BRYOPHYTES PTERIDOPHYTES SPERMATOPHYTES GYMNOSPERMS ANGEOSPERMS DICOTS MONOCOTS Taxonomy breakdown Magic Guarri Taxonomy KINGDOM Plantae PHYLUM Spermatophyta CLASS Angiosperms ORDER Ericales FAMILY Ebenaceae GENUS Euclea SPECIES divinorum Plant Identification How to Identify a Plant ID features ID features of a tree 1) LEAVES (structure and arrangement) - photosynthesis - transportation [gets rid of excess water, cools plant & causes suction through plant] - modification to thorns e.g. Acacia 2) STEMS - carry the leaves - transportation xylem - transports water & minerals from roots to leaves phloem - transports nutrients around plant after photosynthesis - modification to branch to a spine e.g. sicklebush ID features of a tree 3) ROOTS - anchor the plant - absorption of water & minerals - modifications e.g. storage 4) SEEDS - reproduction - dispersal [wind, water, animal, self-propelled] 5) HABITAT and DISTRIBUTION 6) LATEX 7) OVERALL FORM e.g. umbrella thorn Leaf Formations simple bipinnately compound pinnately compound trifoliolate Bifoliolate Mopane Greenthorn Bushmans grape Spikethorn karee White-irnwood African weeping-wattle Sicklebush Acacias Buffalo-thorn Bushwillows Proteas Yellowwoods Marula Sneezewood Wild-plum Cape-ash Leaf Arrangements alternate clustered opposite spiral Stemfruit Common wild fig Common guarri Camphorbush Spikethorn Sourplum Wild-medlar Lowveld numnum Waterberry Sheperd's tree Silver clusterleaf Puzzlebush Identify the tree Silver cluster leaf Formation: spreading crown and horizontal branches, sivery appearance Leaves: grey green with a clustered leaf structure. pubecent leaves. the hairs are greyish silver in colour and cover both sides making the tree look slightly silver from a distance Bark: redish bark on young stems; grey on older Flowers: small whitish cream with very unpleasent smell Seed pods: flat, pinkish colour that form in a cluster Habitat & Distribution: open woodland and bushveld. prefur sandy soils and usually seen at seep lines Plant uses Marula The End.
