Answer:
Transpiration plays an important role in the existence of plants. As discussed, Transpiration plays a significant role by removing excess water from the aerial parts of the plants. The Significance of Transpiration in plants includes: Keeps the cell turgid.
Transpiration pull is especially important at night. It also helps in temperature regulation.
Interstitial growth is the type of growth that occurs within cartilage and results in bone elongation.
It occurs because chondrocytes are capable of dividing and form a cluster of two to four or more cells in a gap.
These groups of chondrocytes are known as isogenic groups or cell nests and they increase the cartilage from within.
In this process it happens because they descend from other chondrocytes that have undergone several mitotic divisions and continue dividing.
Once cytoplasmic constriction occurs in dividing cells, a septum of intercellular substance develops between them, separating the daughter cells.
In this way, interstitial growth develops two types of dispositions:
- If mitosis is carried out in only one direction, we have a group of aligned chondrocytes (axial isogenic group).
- If the divisions are carried out in all directions, we have a coronary isogenic group.
In the epiphyseal lines of long bones, the cell division of chondrocytes occurs in one plane, resulting in the ordering of long columns, which are subsequently invaded by bone tissue.
The division of the chondrocytes and the secretion of a new matrix between the cells, gives rise to a bone elongation of the cartilage from the inside.
Therefore, we can conclude that interstitial growth is the type of growth that occurs within cartilage and results in bone elongation.

Only a tiny percentage of organisms becomes fossils. Soft-bodied organisms are the least likely to become fossils. Quick burial is almost always essential for remains to become fossils.
Hope this helps :)

541 million years ago with the Cambrian explosion, an extraordinary diversification of marine animals, and ended about 252 million years ago with the end-Permian extinction, the greatest extinction event in Earth history.

Explanation:
<u>Answer:</u>
The process of "Osmosis" is modeled in the plant cell diagrams seen here.
<u>Explanation:</u>
Osmosis is the natural gross migration of solvent particles into a zone of higher solute concentration via a selectively permeable membrane, in the path that seeks to balance the amounts of solvents on both the ends. Osmosis as biological membranes are semipermeable, is a critical mechanism in biological systems.
Such membranes are usually impenetrable to massive and polar molecules like polysaccharides, ions and proteins while being porous to hydrophobic or non-polar molecules like lipids and to small molecules as carbon dioxide, oxygen, nitric oxides and nitrogen.
