Answer:
The correct answer will be-
1. Ribosomes produce- proteins
2. Ribosomes attached to- Endoplasmic reticulum
Explanation:
The ribosomes are the cellular organelles which act as a site for the synthesis of proteins through the process of translation. The ribosome consists of two subunits: the large subunit and small subunit.
The ribosomes are found in two forms in a cell: the free form which is suspended in the cytoplasm and some ribosomes attached to the endoplasmic reticulum.
Thus, proteins and endoplasmic reticulum is the answer.
