Final answer:
Plant problems resulting from nitrogen deficiency include reduced growth and chlorosis, while calcium deficiency in plants often causes blossom end rot, particularly evident in fruits like tomatoes.
Step-by-step explanation:
The type of plant problems that result from nitrogen and calcium deficiencies are c) Nitrogen deficiency leads to reduced growth, while calcium deficiency causes blossom end rot in tomatoes. Deficiencies in these essential nutrients result in various symptoms in plants. Nitrogen is a critical component for leaf growth, and its deficiency can cause stunted growth and chlorosis, a condition where leaves lose their green color and turn yellow. Conversely, calcium is vital for the proper development of plant cells, particularly in developing fruits such as tomatoes, and a lack of calcium can lead to issues like blossom end rot.
