A) root cells of a flowering plant B) zygote C) cells of the leaf of a fern D) cells of a bryophyte gametophyte Each of the seven superkingdoms of eukaryotes contains one member that is a complex multicellular organism A) True B) False If you were to remove the anthers from a self-incompatible plant, how would this affect the fertilization its female gametes? A) Fertilization would continue as self-incompatible plants are fertilized with pollen they produce. B) Fertilization would stop, as self-incompatible plants are fertilized with pollen they produce. C) Fertilization would continue, as self-incompatible plants rely on pollen from other individuals. D) Fertilization would stop, as self-incompatible plants rely on pollen from other individuals. 14. Multiple lines of evidence indicate that complex multicellularity has evolved at least six different times. Which of the following superkingdoms include organisms that complex multicellularity? A) plants, animals, fungi, slime molds B) plants animals, fungi, slime molds, red algae, green algae, brown algae C) green algae (and land plants), red algae, brown animals, fungi, slime molds D) Opisthokonta, Archaeplastida, Stramenopila E) Opisthokonta, Amoebozoa, Archaeplastida, Stramenopila Which of the following statements correctly describes a portion of the pine life cycle? A) female gametophytes produce eggs via mitosis B) matured ovaries facilitate seed dispersal C) pollen grains contain female gametophytes D) seeds are produced in the pollen cones

Explanation / Answer

Answers:

6. (D) Production of triploid endosperm

7. (D) Cells of a bryophyte gametophyte

8. (B) False

Complex multicellularity is found in three of the seven eukaryotic superkingdoms, and is thought to have evolved independently at least six times.

9. (C) Fertilization would continue, as selfincompatible plants rely on pollen from other individuals.

10. (D) Opisthokonta, Archaeplastid, Stramenopila

11. (A) Female gametophytes produce eggs via mitosis.
