What is adaxial epidermis?
The Adaxial Epidermis generally has a thick cuticle on the upper (adaxial) surface. Stomata may occur on the upper epidermis but these are most frequent on the lower (abaxial) surface. The Abaxial Epidermis usually has a thin cuticle.
What is adaxial side of leaf?
The adaxial and abaxial sides correspond to the upper and lower sides of the leaf and to the inner and outer sides of the floral organs, respectively. Lateral organs have two cell populations that have different histological features on the adaxial and abaxial sides.
What is the abaxial?
Definition of abaxial : situated out of or directed away from the axis the abaxial or lower surface of a leaf.
What is the Adaxial surface?
Definition of adaxial : situated on the same side as or facing the axis (as of an organ) the adaxial or upper surface of a leaf.
Which is adaxial relative to the other phloem or xylem?
The xylem typically lies adaxial with phloem positioned abaxial.
Where are Bulliform cells present?
leaves
Bulliform cells or motor cells are large, bubble-shaped epidermal cells that occur in groups on the upper surface of the leaves of many monocots. These cells are present on the upper surface of the leaf.
Which has more stomata abaxial or adaxial?
In general, stomatal densities are higher in the abaxial than in the adaxial epidermis of most species, except in the Graminae where there are more or less equal densities on both surfaces.
What is Bulliform function?
Bulliform cells are the cell that is spread among the leaf’s epidermal cells.They are essential for water storage. During stress circumstances, bulliform cells assist to roll leaves to avoid water loss through transpiration. Therefore, they control the process of transpiration.
What are bulliform cells mention its significance?
Bulliform cells are the cell distributed between the epidermal cells of the leaf. They are responsible for storage of water. Bulliform cells help in rolling of leaves to prevent loss of water through transpiration during stress conditions. Hence they regulate transpiration process.
What is adadaxial in medical terms?
adaxial – Medical Definition. adj. Located on the side nearest to the axis of an organ or organism. Of or relating to the side or surface facing or nearest to the axis of an organ, such as the upper surface of a leaf; ventral.
What is the meaning of abaxial?
abaxial, dorsal – facing away from the axis of an organ or organism; “the abaxial surface of a leaf is the underside or side facing away from the stem”.
What does the adaxial epidermis of a leaf look like?
All leaves were scanned from adaxial and abaxial surfaces. Anatomically, the adaxial epidermis shows, in surface view, rare glandular trichomes, consisting of a pedicel and a highly developed glandular head (figure 4).
