{'parenchyma cell': [1, 0, 0, 0], 'ergastic substance': [1, 0, 0, 0], 'chloroplast': [5, 0, 2, 6], 'conidioplast': [1, 0, 0, 0], 'phragmoblast': [1, 0, 0, 0], 'idioblast': [1, 0, 0, 0]}

The correct answer is option 2, Idioblast.

Parenchyma cells are a type of simple plant cell that is typically thin-walled and has living protoplasts. They are involved in various functions, including storage of nutrients and water.

Idioblasts are a specific type of parenchyma cell that contain ergastic substances. Ergastic substances are non-living substances that are produced within the cell and are usually used for storage purposes. Examples of ergastic substances include starch granules, crystals, tannins, and oils.

Option 1, Phragmoblast, is not the correct answer. Phragmoblast is a term used to describe the initial formation of cell plates during cell division in some types of plant cells.

Option 3, Conidioplast, is also not the correct answer. Conidioplasts are specialized cells in fungi that produce conidia, which are asexual fungal spores.

Option 4, Chloroplast, is not the correct answer either. Chloroplasts are specialized organelles in plant cells that are responsible for photosynthesis and contain chlorophyll. They are not specifically involved in the storage of ergastic substances.

In summary, the correct answer is option
