Plant Tissues



  1. How are the plant tissues
    classified according to their
    functions?


Plant tissues(embryonic) tissues, are divided into growth supporting, filling (^)
and photosynttissues), conductive (vascular) tissueshetic tissues (ground (^)
and covering (dermal) tissues.
Embryonic tissues:secondary meristems. primary m Supportingeristems;
tissues: colleFilling and photosynthetic tissues:nchyma; sclerenchyma.
photosynthparenchyma. Coetic parenchyma; storagnductive tissues: e
xylem; phloem. Covering tissues:
epidermis; periderm.



  1. Which are the growth
    tissues of plants? How do they
    classify and where can they be
    found?


The growth tissues of the plants are the
meristems.that produce the plant growth g Meristems are the tissuesiving
birth to all other tissues; they are
formed of undifferentiateintense cell division rate. d cells havingMeristems
classify as primary meristems and as
secondary meristems.
Primary meristems are found in the
apex of the stem, ithe stem, in the basis and tips of n the lateral butheds of
shoots and within the root cap. Primary
meristems are responsible for the


primary growth (lengthening) of the
plant.
Secondary meristems are those that
make the plant g(secondary growthrow in thickn) and they areess
formed by tissues that thicken the
stem: camcambium).bium and phellogen (cork


  1. What is the difference
    between the lateral and the
    apical buds of the plants?


Lateral bmeristematicuds are portions o tissue located f (^) in the base
of the shoots. Apical buds are portionsof meristematic tissue situated in the tip (^)
of the stem and shoots.



  1. What are apical meristems?
    Which type of plant growth
    does this meristem promote?
    Apical meristemsmeristems found in the apex of the are those primary
    stem and in the tips of shoots and roots.
    The apical meristems are responsible for
    the primary growth of the plants.

  2. What are lateral
    meristems? Where can they
    be found and which type of
    plant growth do they
    promote?
