Seagrass is more efficient at capturing carbon dioxide than tropical rainforests are. Like all plants, it needs water to grow. How do aquatic like seagrass intake water?
A: from groundwater below
B: by absorbing it
C: from photosynthesis
D: by using cohesion forces
B: by absorbing it
Seagrass, like other aquatic plants, intakes water through a process called absorption. The correct option would be B: by absorbing it.
To explain further, seagrass is a submerged plant species that grows in ocean beds and coastal areas. Unlike terrestrial plants, which use their roots to absorb water from the ground, seagrass lacks true roots. Instead, they have specialized structures known as rhizomes and root-like structures called roots or rhizoids. These rhizomes and rhizoids help anchor the seagrass in the sediment and also aid in nutrient and water absorption.
Seagrass absorbs water by utilizing its leaves and other aboveground parts, which have tiny openings called stomata. These stomata allow the exchange of gases for photosynthesis and also facilitate the absorption of water. Through this process, seagrass absorbs water from the surrounding environment, including the ocean or saltwater marsh.
It is worth noting that in addition to absorbing water through their leaves, seagrass also takes up dissolved nutrients and gases present in the water column. This ability to absorb water and nutrients efficiently is one of the factors contributing to seagrass's significance as a coastal ecosystem and its carbon storage capacity.
