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.

With less oxygen there is less carbon dioxide being produced for the plants so photosynthesis decreases.
Answer:
Starch
Explanation:
I'm assuming that we are talking about plants and plants store extra glucose as starch molecules.
Answer:
Fertilization
Explanation:
Egg and sperm are cells known as gametes produced by the GAMETOPHYTE of a sexually-reproducing organism via meiosis. Since egg and sperm cells are produced through meiotic division, their chromosomal number is reduced by half of the parental organism. Hence, sperms and eggs are haploid cells (n) produced by a diploid organism (2n).
Sperm is the male gamete while egg is the female gamete. These two haploid gametes fuse in a process called FERTILIZATION, to produce a diploid ZYGOTE that eventually grows into the diploid structure of the organism called SPOROPHYTE. This system of reproduction called ALTERNATION OF GENERATIONS is used by lower and higher plants.
