O The alga photosynthesizes produce sugars the fungus is able to use, while the fungus keeps the alga safe from being eaten.
O The fungus serves as the substrate the alga needs to perform mitosis, while the alga produces enzymes the fungus needs for decomposition.
O The fungus produces the sugars the alga uses for cellular respiration, while the alga provides a safe place for the fungus to live.
O The alga offers camouflage to the fungus against herbivory, while the fungus secretes toxic substances that release nutrients from the rocks to the alga.

Evolution of Photosynthetic Organisms
Algae are autotrophs and can have photosynthesis, however, evolutionary evidence suggests that plants
shared a common ancestor with only green algae and are closest relatives of Charophytes. What evidences
support this statement? How an algal cell is different from fungal cells, even if both are eukaryotes? Why
slime mold is a protist not a fungus even if it does not have chloroplast?

There are three different kinds of phycobiliprotein molecules used to pass light to chlorophyll: phycoerythrin is responsible for capturing green light, phycocyanin is responsible for capturing orange-red light, and allophycocyanin is responsible for capturing red light.Since light can only penetrate to certain depths in oceans, phycobiliproteins capture the light available and pass it through various pathways of phycobiliproteins until the emitted light is red, which is absorbed by chlorophyll. Use the figure below to answer the following questions. (View image attached) 1.

Further studies reveal that the unknown species has fully functional mitochondria.
