This is because green algae are always in water. So, they don't need to prevent water loss because they're always in contact with water.
I DONT KNOW DO YOU?
Green algae lack a cuticle, which is a waxy layer on the outside of plants, because they live in aquatic environments where it is not necessary for them to conserve water or protect against desiccation. The lack of a cuticle allows for easier nutrient exchange with the surrounding water.
Cuticle is a useful adaptation in plants but not algae because plants need a way to retain water and algae obtains water and other materials directly from the water around them.
i dont know i m a student of class 9 and i m searching for the answer for - diff. b/w spirogyra and blue green alga
The cuticle is a useful adaptation in plants but not in algae because: in order for plants to live on land, they need a cuticle to prevent water loss during dry climates. Algae live in the water, therefore they don't need a cuticle to survive. They use their adaptations to absorb the water and nutrients around their watery environments. Source: My straight "A" brain
because it dont need one to produce its water and food
because algae grows in water and doesn't need to be waterproof btw that is what a cuticle does makes it waterproof. So plants need a cuticle because when it rains the leaf can absorb only the amount it needs and the rest just slides down :)
haha ..ur so stupid u dont know the answer and ur site is called wki.anaswers
The scientific name for green algae is Chlorophyta.
blue green algae
To be more specific, it's a WAXY cuticle. Wax is non-polar, thus hydrophobic.This allows for plants to retain water. Algae do not need to because they're habitually in water.
Green algae belong to Kingdom Protista. Green algae is a very diverse type of algae. Actually, green algae is sort of similar to plants. The green algae contain two forms of chlorophyll and capture light energy to produce sugar in similar with the plant. However, unlike the plants the green algae are aquatic. The species are named algae because they are aquatic and make their own food.
