The right option is; a. A tree grows tall
A tree grows tall is an example of cell division at work because growth is associated with cell division. Also, cell division in multicellular organisms such as plant involves tissue growth and maintenance. Cell division is a process of reproduction in which a cell divides into two or more cells. In this process, production of new cells involves DNA replication and there are various types of cell division. Prokaryotes (such as bacteria) divide their cell using binary fission, while eukaryotes divide their cell by mitosis or meiosis in some.
Here's a few: magnesium, oxygen, silicon, phosphate, and aluminum are all found in earth's crust in high proportion. oxygen being the highest proportion of any other element.

Mitosis and meiosis are the ways of cell division which result daughter cells for growth, development and reproduction.
</h2>
Explanation:
Mitosis and meiosis result daughter cells for growth, development and reproduction in the living world.
Mitosis results two similar daughter cells which are generally for growth and development. In asexual mode of reproduction, mitosis helps in increasing the number of cells.
Meiosis occurs in germ cells, and in meiosis, one diploid cell produce four haploid cells.
Meiosis results variations by independent assortment and by crossing over and it helps the sexual mode of reproduction. During fertilization, the resultant daughter haploid cells unite and retains the diploid number of chromosomes.
