Question
Chapter 28.4, Problem 3CC
Summary Introduction
To suggest: The reason why the green algal lineage species colonize the land more likely than the red algal lineage.
Concept introduction: Red algae is the closest algal relative that has a phycoerythrin (photosynthetic pigment), which is reddish in colour and is mostly multicellular organism. Green algae possess the grass-green chloroplasts. They are similar in the pigment composition and structure as in the chloroplasts of plants.

Microtaxonomy (Species and Speciation)
Colletotrichum gloeosporioides is a fungus that causes mango anthracnose. It's a devastating disease being avoided by mango farmers. For example, in the island province of Guimaras, Philippines, one cannot bring mango into the island to avoid contamination of the mango plantations. Guimaras produces the sweetest mango in the world. One challenge in the control of mango anthracnose is that C. gloeosporioides is a species complex. What is a complex and how do we provide clear delineation (if we can) among these closely related species?
Based on the morphology of Opalina and Volvox, which supports the syncytial hypothesis and colonial hypothesis of animal origin?

- MAKE CONNECTIONS The bacterium Wolbachia is asymbiont that lives in mosquito cells and spreads rapidlythrough mosquito populations. Wolbachia can make mosquitoes resistant to infection by Plasmodium; researchersare seeking a strain that confers resistance and does notharm mosquitoes. Compare evolutionary changes thatcould occur if malaria control is attempted using such aWolbachia strain versus using insecticides to kill mosquitoes.
