The outer cells of a blatocyst become the <u>placenta</u>, an organ that offers protection and nourishment.
Placenta, aka afterbirth, is an organ found in a female body that forms around the baby in order to protect and feed it. It provides nourishment for the fetus, keeps it warm, eliminates any infections that may occur, and overall protects the developing baby.
Explanation:
The watermelon fruit when is covered by the molds, a type of fungus which can grow on the moistened substances. The molds can be characterized by their black, green and white spores.
The molds grow on the moistened surface by growing their hyphae which can form mycelium. These hyphae continuously produce enzymes which can breakdown the organic matter present in the watermelon.
Therefore, the matter and energy of the watermelon are transferred to the molds as it forms the next trophic level in the food chain.
D. starch is broken down by enzymes :)
