Differbetween
The key difference between pits and plasmodesmata is that pits are the thin regions of the plant cell wall that facilitate communication and exchange of substances with neighbouring cells while plasmodesmata are microscopic intercellular bridges that connect the cytoplasm of neighbouring cells with each other, ...

What are pits in plants?
Pits are relatively thinner portions of the cell wall that adjacent cells can communicate or exchange fluid through. Pits are characteristic of cell walls with secondary layers. Generally each pit has a complementary pit opposite of it in the neighboring cell. These complementary pits are called "pit pairs".
What is the function of pit?
The pit membrane, which lies in the center of each pit, allows water to pass between xylem conduits but limits the spread of embolism and vascular pathogens in the xylem.
What is the function of pits in plant cells?
Minute openings (pits) in the secondary cell wall of water conducting elements play an important role in water transport in living plants. They allow the flow of water and nutrients from one element to another, linking water uptake in roots with transpiration in leaves.
How are pits formed?
Simple pits are formed on the secondary cell wall of extra xylary fibres (fibers present outside xylem). Ultra-structure of bordered pit: Bordered pits have a complex structure. The pit cavity which is enclosed by the overarching borders is called pit chamber.
What does PIT mean?
PIT
| Acronym | Definition |
|---|---|
| PIT | Process Improvement Team |
| PIT | Pursuit Intervention Technique (police high-speed pursuit tactic) |
| PIT | Performance Improvement Training (various organizations) |
| PIT | Public Internet Terminal (various locations) |
Which simple tissue is characterized by pits?
Thus, the correct answer is 'Sclerenchyma. '
Which is absent in the area of pits?
So, the correct answer is 'Secondary wall'.
Where are bordered pits found?
Bordered pits are present in Vessel wall. Bordered pits are present in Sclerenchymatous cells only. It is abundantly present in Vessels of Angiosperms and Tracheids of ferns and Gymnosperms. These are the condutive tissues of plants which allow fluids to pass from one cell to another.
What is the meaning of Plasmodesmata?
Plasmodesmata (singular: plasmodesma) are microscopic channels which traverse the cell walls of plant cells and some algal cells, enabling transport and communication between them.
What is Plasmodesmata function?
Plasmodesmata are minuscule plasma corridors between plant cells which are of paramount importance for transport, communication and signalling between cells. These nano-channels are responsible for the integrated action of cells within tissues and for the subdivision of the plant body into working symplast units.
Do vessel elements have pits?
The side walls of a vessel element have pits: more or less circular regions in contact with neighbouring cells. Tracheids also have pits, but only vessel elements have openings at both ends that connect individual vessel elements to form a continuous tubular vessel.
Does phloem have pits?
They appear like circular pits. They differ from pits of other cells (as xylem is water conducting tissue in plant) as it allows radial conduction of water I. ... Companion cells - transport of substances in the phloem requires energy. One or more companion cells attached to each sieve tube provide this energy.
