PLANT CELLS AND TISSUES Flashcards
plants are composed of there major organ groups:
roots, stems, and leaves
the most common plant cell type
Parenchyma cells
stores starch oils and water
Parenchyma cells
help heal wounds to the plant
Parenchyma cells
have thin flexible walls
Parenchyma cells
provide support to a growing plant
collenchyma cells
they are strong and flexible
collenchyma cells
celery strings are strands of ______
collenchyma cells
they have unevenly thick cell walls
collenchyma cells
are the strongest plant cell type
Sclerenchyma cells
second cell wall hardened by lignin
Sclerenchyma cells
die when they reach maturity
Sclerenchyma cells
used by humans to make linen and rope
Sclerenchyma cells
two types of plant tissue
meristematic tissue
permanent tissue
are found
in meristems, which are plant regions of continuous
cell division and growth.
Meristematic Tissue
are either undifferentiated
or incompletely differentiated, and they continue to
divide and contribute to the growth of the plant.
Meristematic Tissue
contain meristematic tissue located
at the tips of stems and roots, which enable a plant
to extend in length.
Apical meristems
facilitate growth in thickness or
girth in a maturing plant
Lateral meristems
occur only in
monocots, at the bases of leaf blades and
at nodes
Intercalary meristems
covers the outside of a plant.
- Dermal tissue
protects the plant
Dermal tissue
secretes cuticle of leaves
Dermal tissue
forms outer bark of trees
Dermal tissue
is found inside a plant
Ground tissue
provides support
Ground tissue
stores materials in roots and stems
Ground tissue
