Chlorophyta are usually green in color since their chlorophyll is rarely masked by other pigments. |

Phylum Chlorophyta includes the largest algae, the giant kelps. |
| | A) | T |
| | B) | F |

Rhodophyta are by far the most complex group of seaweeds in terms of thallus forms and size range. |
| | A) | T |

The most common pattern of reproduction in seaweeds is like that of animals, with a diploid adult thallus and haploid gametes. |

8 | |
In some seaweeds, full-grown plants (thalli) can form at both diploid and haploid stages. |
