Leaf Anatomy And Morphology

Leaf Anatomy and Morphology Wrong One organ Which very hold role important in life plants are leaves. Why is that? Because the process occurs in the leaves photosynthesis which produces various food materials for growth. Photosynthesis can taking place in leaf Because leaf own network parenchyma Which contain chlorophyll . Besides chlorophyll, on leaf there is chloroplast (cell shaper chlorophyll), epidermis, And file vessels transport (xylem And phloem). At a glance looks exists equality between structure leaf And stem, is of course thereby? Let We discuss about matter This on description following. If You make slice transverse leaf And observe it start from part top to bottom, you can see the arrangement consisting of upper epidermis, mesophyll, bundles vessels transport, And epidermis lower. Let We know What just Which there is on every part the! a. own tools addition Which originate from modification epidermis, for example trichomes (hair leaf), cell fan, thorns, And etc. Try You search, What Again Which is results from modification epidermison leaf? b. Mesophyll Mesophyll is a layer of tissue in leaves which is composed of cells parenchyma. Arrangement cells parenchyma on mesophyll the situation tenuous so it produces Lots room intercell. On plant dicot mesophyll often time differentiate become network other, that is palisade (network pole) And sponge (network flower coral). On grass And group plant monocot, mesophyll No experience differentiation, but uniform, except mesophyll on sarong file vessels transport monocot. In side That, on plant monocot cells mesophyll on file vessels transport it size more big And content there are few chloroplasts with circumstances wall cell Which more thick. Epidermis Epidermis on leaf is cells Which arranged from One layer cell, Which wall the cell experience thickening. Thickening wall cell on leaf can caused by substance chitin (cuticle) or lignin . On most plant, layer epidermis the leaves only consists from One ply cell, except on leaf plant Ficus (nation banyan). On leaf Ficus, epidermis arranged on two layer cell epidermis. Epidermis leaf own something gap Which works For exchange gas. Gap This known as stomata (mouth leaf). Stomata located on leaf with flankedby two cell closing And surrounded by cell neighbor. Stomata there is in second surface leaf, but most there is in surface part lower And There is also Which only on surface lower. Other case stomata Which only there is on plant Which floating in water, like lotus Which only there is in surfacepart on leaf. In side stomata, leaf Also On plant dicot cells network pole the mesophyll shaped cylinder, the arrangement meeting, And contain chlorophyll. Generally network pole on dicot located in part surface on leaf, but There is also Which there is in second part surface leaf, called leaf isobilateral . Besides That, net pole There is also Which there is in all over surface peripheral leaf, that is on leaves Which ownform cylinder. Structure other Which there is on leaf is network flower coral. Network It is composed of cells that are irregularly shaped, branched, and contain chloroplast. Circumstances arrangement the cells very tenuous. For more explained, can You take note on Picture 2.6. c. File Vessels Transport File vessels transport in leaf there is on reinforcement leaf. Type file vessels transport leaf, The same with Which there is on stem. Bones Which there is on leaf besides works as tool transportation Also give formon leaf And strengthen leaf. d. network additional On a number of plant the mesophyll contain cells Which typical, like channel sap, cells crystal, And gland. Every cells Which typical That own benefitWhich different. a. Leaf Morphology In side the anatomy, Which need You know in learn leaf plant is form outside (morphology). By morphology, completeness leaf consistsfrom parts Which form upih leaf, stalk leaf, midrib leaf (vagina), Andsheets leaf (lamina). Characteristic or characteristic features leaf Which need You take note, that is form whole leaf, form end, base, And edge leaf, as well as form his bones. For more understand about matter This, try You collect a number of leaf from typeplant Which different. Then, observe morphology every leaf the together your friends. So give Name with notice key identification morphology leaf following! Picture1. Miscellaneous form leaf (a) leaf single, (b) leaf compound, (c) leaf compound double.
