What is the term for the flexible column of material that provides support for vertebrate embryos?
Notochord
How are vertebrate embryos evidence of evolution?
All vertebrate embryos look roughly the same, showing that they come from a common ancestor.
What do all vertebrate organisms have in common when they are embryos?
pouches
Do embryos have genetic material?
Yes
Do embryos genetic material?
Yes.
What group of vertebrate embryos contain a moderate amount of yolk because their larvae can obtain their own food?
Amphibians
What is found in all chordates and provides support in embryos and in some adult organisms?
Notochord
All vertebrate embryos develop gills during one of the many growth phases in their development?
It would be more appropriate to say that all vertebrate embryos develop pharyngeal gill slits during one of the many phases in their embryonic development. This is because while gills are specifically present in fishes, pharyngeal gill slits are a general chordate feature.
What contains food for the the plant embryos?
The endosperm contains the stored food that provides energy for the plant. This allows it to begin to grow into a plant.
Why does comparative embryology show similarities between organisms that do not appear to be similar as adults?
Comparative embryology is the study of the similarities and differences in the embryos of different species. Similarities in embryos are evidence of common ancestry. All vertebrate embryos, for example, have gill slits and tails. All of the animals except for fish, lose their gills slits by adulthood. Some of them also lose their tail. In humans, the tail is reduced to the tail bone. Thus, similarities organisms share as embryos may be gone by adulthood. This is why it is valuable to compare organisms in the embryonic stage
Which phyla possesses members that have a notochord?
Chordata is the phylum that possesses members with a notochord, which is a flexible rod-like structure that provides support. This phylum includes animals such as mammals, birds, reptiles, amphibians, and fish.
