Question

As a group, the archaeans Select one: a produce methane b are unique among prokaryotes, because they have mitochondria O c. are not inhibited by antibiotics Od. have large amounts of peptidoglycan in their cell walls e, share 80% of their DNA sequences with the Eukarya the tollowing statements areevidence for the ongin of plants from charophytes, a group of green algae, EXCEPT Select one: O a. Chlorophyll b is present in both groups O b. In both groups, the zygote that forms after fertilization is enclosed in a protective coat. O c. Both groups produce starch as their main storage carbohydrate. O d. Both groups undergo sexual reproduction and have similar sperm structure. All of the following characteristics are common to vascular plants EXCEPT Select one: O a. Predominance of the diploid stage of the life cycle b. presence of phloem and xylem tissues O c. presence of lignin in the cell walls O d. seed production

Explanation / Answer

Ans 1. As a group archeans are not inhibited by antibiotic and unlike bacteria they do not have peptidoglycan amd therefore most antibiotic fail.

Ans 2. The exception is in both groups,the zygote that forma after fertilization is enclosed in a protective coat. Charophytes lived in a aquatic environment and there were no threats of dessication therefore the zygote after fertilization did not have protective coat.

Ans 3. Seed production.

Seedless vascular plants are more derived then non-vascular plants and are defined by their lack of seed production and presence of vascular tissue.
