Skeletal Muscle Systems
Vertebrates move by the actions of muscles on bones.
Tendons attach many skeletal muscles across joints, allowing muscle
contraction to move the bones across the joint.
Muscles generally work in pairs to produce movement: w
MERISTEMATIC TISSUE. Plant cell types rise by mitosis from a meristem.
A meristem may be defined as a region of localized mitosis. The pattern of
plant growth depends upon the location of meristems. Meristems may be at
the tip of the shoot or root (a type
Plants have adapted to a range of environments over the course of their
evolution. As plants grow, their cells become specialized for particular
functions. The patterns of specialized tissue vary in each plant organs-the
root, the stem, and the lea

Parenchyma Cells. Collenchyma cell walls are also irregular in
shape. The thicker cell walls provide more support for th
