Document Summary
Plastid here means chloroplast, word refers to the process of. This is a photosynthetic animal, as chloroplast are not destroyed but incorporated into elysia"s gut cells. Phylum: mollusca (invertebrate but has bodily systems) Retains chloroplasts (functional) in its gut cells from digested specific algae (vaucheria litorea) the functional chloroplast makes it green in colour (no chloroplasts when born/young brown in colour) Heterotrophy: cannot fix carbon, get energy by breaking down already reduced organic forms of carbon (sugars, carbohydrates, proteins, taking reduced organic molecules, breaking them down and using the energy that is reduced. Converting reduced organic molecule, like glucose, breaking them down into simpler molecules, and using the energy that is reduced: ex. Autotrophy: get energy by fixing inorganic forms of carbon (carbon dioxide, takes inorganic molecules, and use light (photoautotroph) or chemicals (chemoautotroph) to convert it to more complex reduced form, ex.
