BIOLOGY QUESTIONS COMPLETELY
SOLVED
, How are Lichens formed? - ANSWERLichens form from a mutual relation of Algae and
Fungus
What is a lichen good for? - ANSWEREarly colonizers of bore rock, organisms eat
them, they provide cover for small organisms, and weavers can use them for dye
Where is Red Algae common? - ANSWERRed algae is more common in water. Has
been found 260m deep
Where is Green Algae common? - ANSWERGreen algae is more common on land, and
shares plant characteristics
Why are algae important to humans? - ANSWERFood, additives, medicine
What biochemical and structural evidence supports that plants and green algae are
thought to have common ancestors? - ANSWERThey share cellulose, and have rich cell
walls, and there is molecular support as well
What does the life cycle of Chara have that is similar to plants? - ANSWERIt has a
haploid and diploid stage, and follows a life cycle
What are the main challenges that needed to be overcome in order for plants to live on
land? - ANSWERDesiccation
Gravity
Mating
Air doesn't filter harmful UV rays
What features of the terrestrial environment made it advantageous for plants to invade
land? - ANSWERSunlight is abundant, less filter for chlorophyll
CO2 is more readily available
No predators early on
What are the adaptations plants have developed to live today? - ANSWERDefenses
Live close to water, to combat dryness
Colonized communities with high humidity
All algae are __________ - ANSWEREukaryotes
What are the 4 major types of plants? - ANSWERBryophytes, Seedless Vascular
Plants, Gymnosperms, and Angiosperms
