Final answer:
The cytoplasm is the medium in which organelles are found, supporting a cell's metabolic processes and hosting various organelles such as mitochondria and ribosomes.
Step-by-step explanation:
The medium in which organelles are found is the cytoplasm. The cytoplasm refers to the contents within a cell, situated between the cell membrane and the nucleus, consisting of a gel-like substance called cytosol which enables the metabolic processes.
The organelles, like mitochondria and ribosomes, are suspended within this cytosol. The cytoplasm performs various functions such as protein synthesis, and the metabolic reactions essential for the cell's survival.
Organelles like the mitochondria serve specific roles such as energy production through cellular respiration, making ATP that powers cellular activities.
