Scientists believe that green algae, Chlorophyta, are the ancestors of land plants. Volvox, a green algae, gives us a clue to this progression in plant form because, as seen here
A)
single cells joined together to form a unique colonial body form.
B)
Volvox has an advanced body structure with cells, tissues, and organ systems.
C)
single cells, that can no longer live independently, joined to form a colony.
D)
Volvox colonies are organized on the organ system level much life flowering plants.

Answer 6

A plant with the dominant trait, wrinkled seeds, is crossed with a plant that has non-wrinkled seeds. All of the offspring are all wrinkled-seeded. What is the likelihood that the gametes of the wrinkled seeded plant contain one non-wrinkled allele?
A)
0%
B)
25%
C)
50%
D)
100%
@Abhisar

Answer 7

If all the offsprings are showing dominant trait then it means that the gamete of wrinkled seeded plant was homozygous.

Answer 8

D

Answer 9

Nopes, 0%

Answer 10

All have wrinkled allele and none have non-wrinkled allele.

Answer 11

Is that making sense?
