Structure, Function, and Disease Physical Plant


Morphology of plants consist of roots, stems, leaves, and flowers.The root serves to tether the body
soil, absorb, conduct water and minerals, and storing food.Anatomical structure of roots
consists of the root tip, the root cap, epidermis, cortex, perisekel,xylem and phloem.
Rod consists of books, segments, axillary buds, and terminal buds.The function of enforcing rods and
strengthen the body of plants, water and continue the mineral substances from the root to the whole body, especially
leaves, and drain the substance of photosynthesis from the leavesthroughout the body. Transport of substances carried
rod, through the xylem and phloem.
Leaf is the site of photosynthesis. The epidermis serves as aprotective layer.
Stomata allow gas exchange and serves as a way of evaporation of water during the process
transpiration. Between the upper epidermis and lower epidermisare composed of mesophyll parenchyma
palisade and spongy parenchyma. In palisade parenchymacontained chloroplasts that contain chlorophyll,
function 'catch' the wave of sunlight as energy for photosynthesis.
Flowers serve as the reproductive organs of plants that supportedreproductive structure, the form
stamens and pistil. Stamen is a set of male reproductive organs.pistil is
female reproductive organs.
Hama is a disorder caused by parasitic organisms. Pests,damaging tissues
or organs of plants so that plant metabolism is disturbed. Plant diseases is
abnormal conditions in plants due to pathogen attack or disruptionto environmental factors.
Examples of plant diseases, such as tungro and stunted grass onrice leaf blight in corn,
and coffee leaf rust.
