NEET BIOLOGY

Detailed explanation-1: -The plant clearly exhibits cell activity by visibly dem-onstrating cytoplasmic streaming, which occurs in animals, plants, and protista. Cytoplasmic streaming in elodea can be measured by observ-ing the movement of chloroplasts throughout the cell.

Detailed explanation-2: -In plant cells, cytoplasmic streaming carries chloroplasts, which are the sites of photosynthesis, from one part of the cell to another. This helps maximize photosynthesis and subsequent cell growth.

Detailed explanation-3: -In this study, a temperature-controlled stage was created in order to investigate the effect of cell temperature on cytoplasmic streaming, and the cells of an aquatic plant (Egeria densa) were used.

Detailed explanation-4: -The leaves of Elodea are quite thin at only two cell layers thick. This makes Elodea an ideal specimen for observing photosynthetic cells and organelles.
