plant tissue Flashcards
plant tissue can be categorized into something:
*Meristematic Tissue
*Epidermal Tissue
*Vascular Tissue
*Ground Tissue
- cells of these tissues are commonly called meristems
- cells of these tissues are actively dividing and give rise
to the organs or other important plant parts - it assists in the major growth of vegetation, it
possess a large nucleus
Meristematic Tissue
different meristems for specific plant parts:
apical meristems
lateral meristems
intercalary meristems
located at the root tips and shoot
tips and responsibilities for the formation and primary
apical meristems
located in the stem and roots on
the lateral side, responsible for the thickness of the
plants
lateral meristems
are responsible for
regenerating removed parts of the plant occurs
between the old tissue regions of the node and leaf
attachment
intercalary meristem
- are single layered that surround the plant body
- its function is to separate the internal system from the
environment, absorption of molecules, minerals,
nutrients, and protection against pathogens - it has specialized cells such as the root hairs to absorb
water and minerals and the leaf hairs to act as a
boundary between too much light and to impale insects
Epidermal Tissue
- provide transport pathways for water, nutrients,
and signaling molecules and support a plant body
against mechanical stresses
Vascular Tissue
transporting water and solutes originating
from the plant–soil interface to the stems and
leaves, and providing mechanical support and
storage
Xylem
transfer the products of photosynthesis
to other area of plants
Phloem
its function in general is to harden and give structural
rigidity to the plant
Ground Tissue
it is specialized to function in
photosynthesis, storage, or transport
parenchyma
providing strength to the plants
Sclerenchyma
provides support, structure,
mechanical strength, and flexibility to the plant
allowing for easy bending without breakage
Collenchyma
