Discussion

21161.	Question : All vertebrates are chordates but all chordates are not vertebrates. Justify the statement.

Discussion

21162.	Question : All vertebrates are chordates but all chordates are notvertebrates'. Justify the statement.
Answer» Solution :Animals belonging to phylum Chordata are fundamentally CHARACTERISED by the presence of a notochord, a dorsal, hollow nerve cord and paired pharyngeal gill slits. The MEMBERS of subphylum Vertebrata POSSESS notochord during the embryonic period. The notochord is replaced by a cartilaginous or bony vertebral column in the adult. Thus, all vertebratesare CHORDATES but all chordates are not vertebrates.

Discussion

21163.	Question : All vertebrates are chordates but all chordates are not vertebrates. Justify this statement.
Answer» SOLUTION :All VERTEBRATES have notochord during embryonic development. Later it is replaced by the vertebral COLUMN. But in LOWER chordates like prochordates, vertebral column is not present. They have only notochord in the adult or larval.Hence it is said that all vertebrates are chordates but chordates do not have VERTEBRATE characters.

Discussion
