Answer: diplontic plant
Explanation:
The mosses belongs to the phylum of non-vascular plants. They produce spores instead of seeds. They do not produce flowers, true roots and wood. They do not posses a vascular system. They exhibit a diplontic life cycle. The diplontic life cycle involves the formation of diploid gametes. In mosses the diplontic life cycle the mosses produces diploid cells and in only one stage they produce haploid cells.
<em>complete chemical equation is in the attachment below:
</em>
(1) they keep toxic substances out of the cell;
(2) they contain receptors and channels that allow specific molecules, such as ions, nutrients, wastes, and metabolic products, that mediate cellular and extracellular activities to pass between organelles and between the cell and the outside environment;
(3) they separate vital but incompatible metabolic processes conducted within organelles.
