Explanation:
Microtubules are polymers of tubulin and they are part of the cytoskeleton. The roles of the microtubules are to maintain the shape and structure of the cell, intracellular transport, they are structural part of the cilia an flagella, they are involved in cell division etc.
Tubulin that is the basic unit of microtubules is composed of two globular proteins, alpha and beta tubulin. Alpha and beta subunits spontaneously form dimers which then assemble into oligomers, then in chains (protofilaments); that can form a variety of intermediate structures such as single and double rings or spirals. Protofilaments that associate side-by-side form sheets of protofilaments which then curle to form a tube or cylinder (closing of microtubule). Continued growth of microtubules occurs by the direct addition of more dimers on + side.

Bulb serves as a food mass supplying the plant with adequate nutrients that will allow for production of offspring or more onions that can survive.
<h3 /><h3>What is an ecosystem?</h3>
An ecosystem is a community of plants and animals that live together and benefits from each other.
- Survival in an ecosystem is based on the ability of the individual to reproduce their kinds that will survive.
- The bulb in onions act as a store of food for the plants to feed on and grow till maturity where it can also produce more of it's kind.
Without the bulb that stores food the plants cannot grow and therefore the chances of survival is low.
Therefore, the bulb serves as a food mass supplying the plant with adequate nutrients that will allow for production of offspring or more onions that can survive.
