Question

Choose the false statement:

A) Plants evolved onto the land quite successfully 100’s of millions of years before fungi ever appear on the land.

B) Fungi and animals are both heterotrophs; however, they differ in that fungi digest their food and then absorb it, whereas animals ingest their food then digest it.

C) Lichens are organisms consisting of a complex of both fungi and algae; these exist together in a mutualistic symbiotic relationship.

Choose the false statement:

A) The earliest plant-like autotrophs were marine seaweeds; this group of large algae is included in the K. Protista because they exhibit very little specialization or division of labor.

B) On land, plants are the most important primary producers, whereas in aquatic ecosystems, most primary productivity is carried out by microscopic cyanobacteria and phytoplankton.

C) The shift from a predominant gametophyte to a predominant sporophyte does not occur until the rise of Gymnosperms, after the Permian extinction (250-300 mya).

Choose the false statement:

A) While not the only taxonomic system in use today, the one we used the most organized all creatures into 5 distinct kingdoms; among these, one is prokaryotic and the other four are eukaryotic.

B) Among the 5 kingdoms, Monera and Protista each contain both autotrophs and heterotrophs, whereas each of the other three kingdoms is either exclusively one, or the other.

C) Among the four eukaryotic kingdoms, all of them are polyphyletic, except for K. Plantae.

Multiple choice: Which of the following represents a major evolutionary change that was not present in lower vascular plants (ferns) and appears for the first time in higher vascular plants (Gymnosperms and Angiosperms):

A) The first appearance of true roots.

B) Flagellated gametes are replaced by the pollen, thus restoring the sexual side of the life cycle as a contributor to genetic variation.

C) All higher vascular plants can produce flowers but lower vascular plants (ferns) cannot.

Answer 1

Question 1

Option A :- FALSE

Reason :- Fungi colonized land just at the same time as plants about 460 million years ago.

Option B:- True

Readon:- Fungi and animals both are heterotrophic organism . The only difference in their mode of nutrition is that instead of first ingesting and then digesting the food material. The fungi first digest the organic material and then absorb. The majority of fungi upon dead decaying matter.

Option C:- True

Reason:- Lichen is a symbiotic relationship between be algae and fungus.They share a mutualistic relationship in which they both help each other and support each other's coexistence.
