PLANT ADAPTATIONS ON CAMPUSINTRODUCTIONThe purpose of this lab is not to be able to identify every plant you see. The purpose of this lab is to learn how to identify the different adaptations a plant may have evolved for survival in a particular environment. In this lab, you will be responsible for learning the names and adaptations of the plants discussed during the tour of the campus and Wildlife Sanctuary.Leave TypesSimple:Compound:Singly:Doubly:4010025571500Venation:Pinnate:Palmate:Parallel:314325011493500Leaf Arrangement:Alternate:Opposite:Whorled:Plant Species:SpeciesCharacteristicsFamily/LocationOtherAcaciaFabaceaeAsh TreeOleaceaeBladderpodCapparaceaeBrazilian PepperAnacardiaceaeBlack SageLamiaceaeBulrushCyperaceaeCactusCactaceaeCalifornia BuckeyeSapindaceaeCalifornia BuckwheatPolygonaceaeCaliforniaRedbudFabaceaeCalifornia SagebrushAsteraceaeCalifornia Sweet bayLauraceaePlant Species (cont)SpeciesCharacteristicsFamily/LocationOtherCaster BeanEuphorbiaceaeCatalina CherryRosaceaeCatalina IronwoodRosaceaeCattailsTyphaceaeCeanothus (Mt.

The sepals of a flower are collectively called the calyx and act as a protective covering of the inner flower parts in the bud. Sepals are usually green, but in some flowers (e.g., the lily and the orchid) they are the same color as the petals and may be confused with them,Petals: The whorl of petals is known collectively as the corolla [Lat.,=little crown]. The number of petals is usually constant within groups (e.g., five in the rose family), as are the numbers of the other organs.Stamens: The stamen (microsporophyll), is often called the flower's male reproductive organ. It is typically located between the central pistil and the surrounding petals. A stamen consists of a slender stalk (the filament) tipped by a usually bilobed sac (the anther) in which microspores develop as?grains.Pistils: the female reproductive organ of flowering plants, consisting of an ovary, style (sometimes absent), and stigma. The carpels are separate or fused to form a single pistilPlant FamilySepalsPetalsStamensPistilsOthersMustard (Brassicaceae)44 arranged in an X or H6 - 4 Tall & 2 Short1Seed pods - Radial pattern around the stalk called a racemeMint (Lamiaceae)5 United5 United Petals – 2 lobes up, 3 down4 – 2 Long & 2 Short2 UnitedStems are Square with opposite leaves, aromaticPea (Fabaceae)5 United5 forming Banner, Wings, and KeelUsu. 10 (sometimes 5)1Pea-like pods and often pinnate leavesSunflower (Asteraceae)In a ring5 petals fused together5 fused around pistilStigmasComposites with many small flowers in a diskCactus (Cactaceae)NumerousNumerousNumerous2 or more united carpelsSucculent plant with spinesRose (Rosaceae)55NumerousNumerousOval, serated LeavesSumac (Anacardiaceae)555 or 1013-lobed or pinnate leaves, single seeded red or white fruitGrass (Poaceae)MinimalMinimal33 united carpelsKnee-like nodes on the flower stemsMustard (Brassicaceae)22860047625762000171450Mint (Lamiaceae)Pea (Fabaceae)22860020320Sunflower (Asteraceae)171450118745Rose (Rosaceae) 3238501181101581150102870Sumac (Anacardiaceae) ................
