Detailed explanation-1: -Cytoplasmic bacteria exhibit cytoplasmic streaming. This is also known as protoplasmic streaming. This helps in the movement of substances. Cytoplasm helps bacterial cells in growth, metabolism, replication, etc.
Detailed explanation-2: -Cytoplasmic streaming, known as cyclosis, is a movement of cytoplasm in various organisms including bacteria, higher plants, and animals (Williamson and Ashley, 1982; Theurkauf, 1994).
Detailed explanation-3: -Abstract. Chloroplasts migrate in response to different light intensities. Under weak light, chloroplasts gather at an illuminated area to maximize light absorption and photosynthesis rates (the accumulation response). In contrast, chloroplasts escape from strong light to avoid photodamage (the avoidance response).
Detailed explanation-4: -Cytoplasmic streaming, or cyclosis, is an energy-consuming event that occurs in plant cells and is used to distribute nutrients in the cytoplasm. It is common in larger cells, such as sieve tube elements, where diffusion is not adequate for substance distribution.
