Renu is correct because all plant cells, including roots, contain plastids. Roots have leucoplasts for storage, even though they lack chloroplasts for photosynthesis.
Two students, Renu and Rohit, were having a discussion on the plastids. Renu emphasised that all parts of the plants, even roots, contain plastids. However, Rohit did not agree with the statement and told her that plastids are absent in plant roots since the roots are underground and do not need to perform photosynthesis. Who is correct? Justify your answer.

Renu is correct because plastids are present in all plant parts, including roots. While roots do not perform photosynthesis and lack chloroplasts, they contain leucoplasts, which store food materials like starch. Plastids are not limited to photosynthesis; they perform various functions. Therefore, plastids are present in roots, supporting Renu’s statement
