Answer:
True.
Explanation:
Prokaryotes and eukaryotes shows various similarities as well as differences among themselves. The eukaryotes have well defined nucleus whereas such nucleus is absent in prokaryotes.
Prokaryotes are much smaller in size than eukaryotic cells. The small area has large surface area to volume ratio. This ration helps in the process of diffusion and metabolism in prokaryotes. Due to their small size, prokaryotes have large surface area to volume ratio than eukaryotic cells.
Thus, the correct answer is option (a).
Tissue is a group of cells that work together to perform a specific function.
Answer:
A) Vascular cambium
Explanation:
(The vascular cambium is a type of cell found in lateral (not apical) meristems and is involved in secondary (not primary) growth.)
The correct answer is a eukaryote. While it would be an impulse to answer prokaryote since the first thing that will come to our minds if we deal with a microorganism that thrives in extreme environments (i.e. hot thermal vents) will be archea, which are prokaryotes. But in this case, it is clearly specified that the single-celled organism has a nucleus which is the characteristic feature of eukaryotes.
Bacteria is incorrect as bacteria are prokaryotes. Plant is incorrect as all plants are multicellular organisms.
