Answer:
1.The group of organisms with cells which contain of nucleus and other membrane bound organelles are called Eukaryotes. These organisms have their DNA arranged in the chromosomes, bounded by histones proteins. They have diversity of forms, thus they can be colonial, unicellular or multicellular in forms. Their cells reproduced by mitosis and meiosis for gamete formation.
Reproduction can be sexual and asexual. Their ribosomes are found in the cytosol, and they are larger than that in prokaryotes, but ribosomes in chloroplast and mitochondria are similar as that in the Prokaryotes (70s). Plants and complex animal cells are examples.
Group of unicellular organisms which lack membrane bound nucleus, and other organelles, are called Prokaryotes. Their two domains are the bacteria and archaea. They reproduce asexually only, by fusion of gametes. Due to lack of membrane bound organelles, their water soluble components and cellular inclusions (metabolites and DNA) are found in the cytoplasm bounded by the cell membrane.
<u>When viewed under microscope. Prokaryotes are similar to Eukaryotes as follows. </u>

I think only twice but I'm not for sure
Answer:
1. C
2. B
Explanation:
1. When a plant cell looses some water due to dehydration or being placed in a hypertonic solution, the term used to describe the cell's intial, not severe shrinkage is 'flaccid'.
Here, it's clear that the cell shrank so much that the cell membrane pulled away from the cell wall. The correct term for this severe shrinkage is 'plasmolysed'.
We don't use 'wilted' as a term to describe a cell. We use it to describe the plant as a whole.
2. This is the function of each. Water and ions in xylem and sugars like sucrose in phloem.
