Answer:
The most diverse group of seedless vascular plants are <u>the ferns .</u>
Explanation:
Ferns -
Ferns are the most advance seedless vascular plants and is the most diverse group . Ferns have branching roots and large leaves . But the whisk ferns , have lack of roots and leaves due to evolutionary reduction . In the process of evolutionary reduction , the natural selection reduces the size of the structure which no longer favors the particular environment . Hence , Photosynthesis in whisk ferns takes place in their green stem .
Answer:
All the options are true except option D.
Explanation:
Archaea are a group of prokaryotic organisms i.e. they lack a membrane bound nucleus. They are one of the the three domains of life (the other two being bacteria and eukarya). Archeans possess a cell wall like bacteria but it is not composed of peptidoglycan, like bacteria cell wall.
Archeans are generally known to be found in very severe environmental conditions, hence, they are referred to as extremophiles e.g Some are thermoacidophiles i.e. thrive in very hot and acidic environment while others are extreme halophiles i.e. thrive in salty regions. Archeans known as methanogens produce methane gas as a product of metabolism from carbon dioxide and hydrogen.
However, the domain archeae was only found to be in existence recently after the domain bacteria, hence, they are not considered to evolve before the domain bacteria.

I originally asked for the images but I will give it my best shot at answering your question without them! :D
There are only three types of plant tissues:
1. Dermal
2. Ground
3. Vascular
The dermal tissue is the outside of the plant's root, stem, or leaf, A.K.A the the skin. If you're looking at a circular image, what ever is pointing to the outside ring of the stem is the dermal tissue.
The ground tissue is the flesh of the plant that is inside the dermal tissue. It surrounds the vascular tissue in the middle of the stem. Whatever letter is pointing to the wide, fleshy ring, that is touching the dermal tissue is the ground tissue. It is the largest part of a plants stem, roots, or leaves.
Lastly, the very inner ring or rings of the plant is the vascular tissue. It's made up of xylem and phloem. This can be found in many different places depending on the part of the plant, but what you're looking for is tiny circles within the ground tissue. If you're looking at the roots, you will see one circle in the very center of the plant, surrounded by ground tissue. If you're looking at the leaves, you will see one circle as well, and additionally other tiny circles throughout the ground tissue in each wing. Lastly, if you're looking at the stem, you'll see a circle of tiny circles within the ground tissue. These small circles are all vascular tissue.
