Prior to 1900, sea levels rose at maximum, 4 cm per year. Since 1900 sea levels have risen 11 cm per year.
<h3>How sea level is measured?</h3>
- Tide stations and satellite laser altimeters are the main tools used to measure sea level.
- The height of the sea as measured along the shore in relation to a particular place on land is what tide stations all around the world tell us about what is happening locally.
- NASA uses satellites to measure sea level all over the world.
- Height of the ocean's surface, often known as sea level, is measured by the Jason-3 satellite using radio waves and other equipment.
- It studies how the global sea level is changing over time for the entire Earth every 10 days.
- The average sea level is 6,371.001 km (3,958.756 mi), and it is 6,356.752 km (3,949.903 mi) at the poles.

The plants can be classified based on their vascular and reproductive structures. The plant given in the image belongs to the Bryophyta.
<h3>What is Bryophyta?</h3>
The non-vascular plants that are a part of the plant classification are found in moist places and are small in size belongs to the Bryophyta.
The plant of this classification have a leafy multicelled plant body, that lacks true leaves, roots, and stems. They are green plants and also contains chloroplast for food synthesis.
The vascular tissue like xylem and phloem are completely absent and hence the transportation does not occur through specialized systems.
Therefore, option A. Bryophyta is the plant growing on the rock.

The correct answer is (b.) euglenophytes. Phosphorescence is a phenomenon associated with an algal division called euglenophytes. Euglenoids are one of the most known flagellates which are excavated eukaryotes of the phylum euglenophyte. Euglenophytes are single-celled plant-like protists that have no cell wall.
It's both! Scientists really can't agree on it.
