Study Notes
Organizational Levels in Living Organisms
- The level of organization characterized by tissues grouped together to form an organ performing a particular function is the organ level.
Circulatory Systems
- The type of circulatory system that involves blood being circulated through arteries, veins, and capillaries is the closed circulatory system.
Embryonic Development
- Embryos with three germinal layers, including mesoderm between ectoderm and endoderm, are triploblastic.
Body Symmetry
- The type of symmetry characterized by any plane passing through the center dividing the body into two symmetrical halves is bilateral symmetry.
Cellular Organization
- Cells arranged as loose aggregates with no specific tissue formation characterize the cellular level of organization.
Organizational Levels in Animals
- The category of animals with a few organs coordinatively performing a certain physiological function is the organ system level.
Learn about the classification of animals based on cellular arrangement, body symmetry, and organ systems. Understand the levels of organization, from cellular to organ level, in different animal groups such as Porifera and coelenterates.
