Dandelion have seeds better adapted to be caught by thewind and transported to another location.
Lianas are climbing … vines that be adapted to livewoody can alldrape in different environments rainforesttrees. they have and help plants survive.adapted to life inrainforest by havingtheir roots in theground andclimbing high intothe tree canopy toreach availablesunlight
Epiphytes are plantsthat live on the surfaceof other plants,especially the trunk andbranches.They grow on trees totake advantage of thesunlight and canopy
Epiphytes: This tree hasBromeliads and mossesliving on the surface of itsbark
The leaves ofBromeliads form avase to hold water.This Pineapple is anexample of abromeliad
Rhizophora:In deltasand along ocean edgesand river estuaries,trees have adapted toliving in wet, marshyconditions. These trees,called mangroves, havewide-spreading stiltroots that support thetrees in the tidal mudand trap nutritiousorganic matter
Desert plants have adapted tothe extremes of heat and aridityby using both physical andbehavioral mechanisms, muchlike desert animals. Xerophytes, such as cacti,usually have special means ofstoring and conserving water.They often have few or noleaves, which reducestranspiration.
Xerophytes adaptations:1.Tick cuticle.2.Stomata hidden in crypts ordepressions in leafe surface(less exposure to wind andsun).3.Reduction in size oftranspiration on surface (lowerleafe only)4.Increased Water storage.5.Thicker leaves and stems, orleaves reduced in number, orleaves drop off during dryseasons.6.Leaves covered with silveryhairs (creates wind break &light reflective surface)7.Deep taproots or widespeading fibrous roots near thesoil surface.
Phreatophytes are another group of plants that haveadapted to arid environments. Phreatophytes, like themesquite tree, have adapted to desert conditions bydeveloping extremely long root systems to draw waterfrom deep underground near the water table.
The Creosote Bush is on the most successful of all desertspecies because it utilizes a combination of many adaptations.instead of thorns, it relies for protection on a smell and tastewildlife find unpleasant. it has tiny leaves that close theirstomata (pores) during the day to avoid water loss and openthem at night to absorb moisture. Creosote has an extensivedouble root system -- both radial and deep -- to accumulatewater from both surface and ground water.
Some plants, such as theOcotillo, survive by becomingdormant during dry periods,then springing to life when waterbecomes available.The Ocotillo also has a waxycoating on stems whichserves to seal in moistureduring periods of dormancy.
Desert plants must act quicklywhen heat, moisture and lightinform them its time to bloom. Ephemerals send out flowerstalks in a few days.Ephemerals such as the desertsand verbena usually germinatein the spring following winterrains. they grow quickly, flowerand produce seeds before dyingand scattering their seeds to thedesert floor.
The Desert Paintbrush isanother ephemeral that quicklyblooms and scatters its seedswhen its active
Aquatic plants like this fringedwater lily have not neededadaptations for strengtheningthemselves. they are supportedby the water they live in. Theyalso do not need as many rootssince they live in the water.
Defensive Adaptations: Plantsas we know have evolvedways to defend themselvesby using sharp spines, thornsor hairs; cellulose that makesthem hard to digest, orcreating toxic chemicals.Another unusual way someplants have evolved to defendthemselves is though mimicry- that is they evolve to looklike another plant that ispoisonous and animals arefooled into believing that theyare poisonous.
