Question

Some green algae exhibit alternation of generations. All land plants exhibit alternation of generations. No charophytes exhibit alternation of generations. Keeping in mind the recent evidence from molecular systematics, the correct interpretation of these observations is that:_________
A) charophytes are not related to either green algae or land plants.
B) plants evolved alternation of generations independently of green algae.
C) alternation of generations cannot be beneficial to charophytes.
D) land plants evolved directly from the green algae that perform alternation of generations.
E) scientists have no evidence to indicate whether or not land plants evolved from any kind of alga.

Answer 1

Option (B) is Right Answer

Explanation:

    (B) Plants evolved alternation of green algae

• Alternation of generations, with the haploid plant called a gametophyte, and the diploid plant called a sporophyte
• Security of the embryo, development of haploid spores in a sporangium, arrangement of gametes in a gametangium, and an apical meristem
• Plants perform photosynthesis, the procedure by which plants catch the energy of daylight and use carbon dioxide from the air to make their own food
