Study Notes
Physiology
- Physiology is the study of the functions and processes that occur within living organisms.
Exchange of Substances
- In multicellular organisms, the exchange of substances occurs through specific cells, tissues, or organs that are adapted for this purpose.
Single-Celled Protists
- Single-celled protists exchange materials with their surroundings directly across their cell membrane.
Sac-Bodied Organisms
- In sac-bodied organisms like jellyfish, the diffusion of materials is facilitated by the large surface area of their gastrovascular cavity.
