Answer 1

Explanation:

PLACENTA - The placenta is an organ that develops in your uterus during pregnancy. This structure provides oxygen and nutrients to your growing baby and removes waste products from your baby's blood. The placenta attaches to the wall of your uterus, and your baby's umbilical cord arises from it.

THALAMUS -The thalamus is a small structure within the brain located just above the brain stem between the cerebral cortex and the midbrain and has extensive nerve connections to both. The main function of the thalamus is to relay motor and sensory signals to the cerebral cortex.

ANTHER - Like all living things, flowering plants must reproduce. The anther is a key structure in the reproduction of flowering plants. It sits atop the filament of the male structure known as the stamen.

STIGMA - The stigma is located in the gynoecium of the flower. Its main function is to attract the pollen grains from the air with its sticky tip for reproduction to take place.
