Study Notes
Multicellularity
- A disadvantage of being a multicellular organism is that it needs to find a mate in order to reproduce.
- A characteristic advantageous for survival in terms of evolution is being multicellular.
Development and Systems
- A multicellular organism needs time to build and develop its systems, including the vascular system.
- The vascular system in multicellular organisms is responsible for transporting nutrients and oxygen to cells and removing waste products.
Nutrition and Diet
- A multicellular organism needs to hunt for food because it is a heterotrophic organism, unable to produce its own food.
- The main purpose of taking vitamin supplements is to fill nutritional gaps in the diet.
Body Structure and Symmetry
- Cephalization refers to the concentration of sensory organs in the head region of an organism.
- Bilateral symmetry and cephalization are significant in organisms because they allow for more efficient movement and sensing of the environment.
- Radial symmetry is characteristic of organisms such as starfish and sea urchins.
Phylogeny and Classification
- The purpose of a cladogram in biology is to depict the evolutionary relationships between organisms.
Movement and Intelligence
- Bilateral symmetry and cephalization are associated with two planes of movement.
- Filter feeding is a mechanism used by some organisms to capture food particles from the surrounding environment.
- There is a relationship between movement, intelligence, and nervous system function, as more complex movements require more developed nervous systems.
