7
In what way is Volvox an example of an organism with primitive traits (like Chlamydomonas) that yet demonstrates some structural advances similar to Viridiplantae?

A)The nucellus
B)The access channel
C)The micropyle
D)The foramen

What process creates spores during the alternation of generations life cycle pattern?
A)Sporogenesis
