Answer: Fatty acids are fats that have acidic carboxyl groups on them. Something like CH3-(CH2)n-COOH Unsaturated fatty acids have double bonds between 1 or more of the carbons in the chain. They are unsaturated with hydrogen, but can be hydrogenated chemically. Fatty acids have many roles, but a very common one is to form the lipids in membranes. In that case two fatty acids are usually joined to phosphate plus some others.

Answer:
The organism is classified as protist or plant based on whether is single celled or multicellular and whether it makes its own food.
Explanation:
Both, protists and plants are eukaryotic meaning that these have nucleus in their cells and organelles bound by membrane. Unlike plants which may be multicellular, protists are single celled. Hence, a botanist must investigate to find if the cells are multicellular or not.
Another important feature is that if the botanists finds that the organism produces its own food, then it is a plant. As plants get their own food by combining the sunlight captured with carbon dioxide from the air through process called photosynthesis.
