Document Summary
Biology 1204: evolution of eukaryotes midterm study guide. Lab 2: archaeplastida: relationships of green algae and plants. Examine the major trends in morphology and life cycles within the green algae and how these may have lead to the evolution of plants. Archaeplastida is a type of eukaryotic group of organisms. Archaeplastida = (cid:498)ancient plastid(cid:499) referring to the fact that this eukaryptic group acquired their chloroplasts via primary endosymbiosis of a cyanobacteria ancestor. All photosynthetic organisms have chlorophyll a, carotene, and xanthophyll. Green algae, as suggested by the title of lab 2 are most closely related to plants. Evidence that green algae is more related to plants than red algae: red algae. Both gametes are motile and are the same size and shape. Female gamete is larger than the male gamete but both are still motile. Female gamete is larger and non-motile and the male gamete is smaller and motile. Oogamy is in all plants and animals, and in some algae.
