The word sponge is more appropriate to use than Underground river since an underground river can loose water while an aquifer cannot loose water, unless it is open-air and above ground. then the aquifer would slowly loose water due to evaporation from the sun.

I found the exercise on the internet. Attached is the chart and the rows. On the left we have "plant tissue", then on the middle top - "dermal" - and just below - "ground". Straight in front of "ground", the term is "c<span>ollenchyma".
The correct row would be D.
1. is vascular because that's the other type of plant tissue besides the ones that are already present in the chart.
2. and 3. - s</span>clerenchyma and parenchyma - are indeed types of ground tissues next to collenchyma.
4. and 5. - x<span>ylem and phloem - are the types of tissues present in vascular plants, they work as vessels where water and nutrients are conducted.</span>
The earliest life forms we know of were microscopic organisms (microbes) that left signals of their presence in rocks about 3.7 billion years old.
