Answer:
An organelle is a subcellular structure that has one or more specific jobs to perform in the cell, much like an organ does in the body. Among the more important cell organelles are the nuclei, which store genetic information; mitochondria, which produce chemical energy; and ribosomes
The answer for the first one would be the Alveoli
the second one is the pituitary gland
Firstly, there are major differences in cell structure between animal and plant cells such as how plant cells have cell walls, large central vacuoles, and a basic rectangular shape, and how animal cells are generally rounder, and have lysosomes and centrioles. However, as an embryo to a fetus, all of us develop stem cells that can be anything and eventually are specialized. This is how we have blood cells which are specifically engineered to compose the blood, and how we also have epithelial cells which compose the skin. Both of these types of animal cells look completely different, but that is because their specialization is not the same despite the fact that their basic parts can be. In order to have specialized cells, they need to adapt and develop a certain structure to function.
