<h3>What is the bone matrix?</h3>
The bone matrix is that part of the bone tissue that forms most of the mass of the bone.
The bone matrix is comprised of organic and inorganic substances. The organic component of the bone matrix includes the following:
However, the inorganic component is mainly;
inorganic bone salts
hydroxyapatite
Therefore, the components that are part of the bone matrix are as follows:
- Osteoid
- Calcium salts

Answer:
Brassinosteroids are synthesized from phytosterols and they promote plant growth and development by modulating cellular processes (e.g, cell division, elongation, photomorphogenesis, responses to environmental stimuli, etc).
Explanation:
Brassinosteroids are phytohormones similar to steroid hormones. Phytosterols include sitosterol, campesterol, and stigmasterol, i.e., lipid (cholesterol) molecules that form the cell membranes. These polyhydroxylated steroidal phytohormones play a wide range of cellular roles during plant growth, development and immunity. Examples of brassinosteroid functions include plant development, xylem differentiation, responses to biotic/abiotic stresses, reproduction, etc. For example, campesterol, which is a precursor of brassinosteroid hormones, is an integral membrane component that functions during plant embryogenesis by regulating the permeability of cell membranes and by altering membrane-associated proteins, as well as signal transduction pathways.
