Parts 4 and 5 explore invertebrate biology, specifically focusing on photosynthesis and kleptoplasty within the animal kingdom. The key concepts involve understanding whether invertebrates are capable of performing photosynthesis, a process primarily associated with autotrophic organisms such as plants and algae. Additionally, the discussions involve examining how animals acquire energy generally and whether certain invertebrates have adapted mechanisms to perform photosynthesis through kleptoplasty, a phenomenon where organisms retain functional plastids derived from algae. The topics also consider other known examples of kleptoplasty and its implications for understanding invertebrate biology and evolution.

Photosynthesis is a process by which autotrophic organisms convert light energy into chemical energy stored in glucose, primarily involving chloroplasts. In animals, energy acquisition predominantly occurs via heterotrophic means—consuming other organisms or organic material. Unlike plants, animals lack the cellular organelles—chloroplasts—necessary for photosynthesis. Some invertebrates, however, have developed extraordinary adaptations that allow them to participate indirectly in photosynthetic processes through kleptoplasty, where they retain chloroplasts from ingested algae. For instance, sacoglossan sea slugs sequester chloroplasts from algae, enabling them to perform photosynthesis temporarily, which demonstrates a unique form of symbiosis and resource utilization within the animal kingdom (Hultgren et al., 2019).

The invertebrates in question, specifically sacoglossan sea slugs like Elysia chlorotica, have demonstrated the ability to maintain functional chloroplasts derived from their algal prey. While these animals do not possess the innate cellular machinery to perform photosynthesis independently, the kleptoplasts they retain can function within their tissues, allowing them to synthesize organic compounds using light energy. This process has been studied extensively, revealing that these slugs can, in fact, perform a form of photosynthesis, but it depends heavily on the retention of chloroplasts originally acquired from algae. Other invertebrates, such as certain cnidarians and mollusks, also display varying degrees of symbiotic relationships with photosynthetic microorganisms, but true photosynthesis by invertebrates remains limited primarily to kleptoplasty phenomena (Pierce et al., 2019).

There are additional examples of kleptoplasty in the animal kingdom. For example, some species of sea slugs and sea spiders exhibit this phenomenon, where they incorporate and maintain functional chloroplasts from algae or other sources temporarily. These symbiotic relationships offer survival advantages, particularly in nutrient-limited environments, by enabling the animals to harness energy directly from sunlight. Research continues to uncover the molecular mechanisms that enable these animals to sustain and utilize stolen plastids, suggesting that kleptoplasty could represent an evolutionary transitional process towards mutualistic symbiosis or even autonomy in photosynthetic capacity (Müller et al., 2020).
