Term | Definition |
---|---|
Asexual Reproduction | Asexual reproduction is a mode of reproduction by which offspring arise from a single organism, and inherit the genes of that parent only; it is reproduction which almost never involves ploidy or reduction. |
Cell | the smallest structural and functional unit of an organism, typically microscopic and consisting of cytoplasm and a nucleus enclosed in a membrane. Microscopic organisms typically consist of a single cell, which is either eukaryotic or prokaryotic. |
Cephalization | the concentration of sense organs, nervous control, etc., at the anterior end of the body, forming a head and brain, both during evolution and in the course of an embryo's development. |
Closed Circulatory system | Closed circulatory systems have the blood closed at all times within vessels of different size and wall thickness. In this type of system, blood is pumped by a heart through vessels, and does not normally fill body cavities. |
Coelom | the body cavity in metazoans, located between the intestinal canal and the body wall. |
Colonial | a colony refers to individual organisms of the same species living closely together, usually for mutual benefit, such as stronger defense or the ability to attack bigger prey. |
Fluid Feeding | Fluid feeders are organisms that feed on the fluid of other organisms. It can refer to: Hematophagy, feeding on blood. Nectarivore, feeding on nectar. |
Endoskeleton | an internal skeleton, such as the bony or cartilaginous skeleton of vertebrates. |
Excretion | the process of eliminating or expelling waste matter. |
Exoskeleton | a rigid external covering for the body in some invertebrate animals, especially arthropods, providing both support and protection. |
Filter Feeding | feeding by filtering out plankton or nutrients suspended in the water. |
Free-living | living freely and independently, not as a parasite or attached to a substrate. |
open circulatory system | Closed circulatory systems have the blood closed at all times within vessels of different size and wall thickness. In this type of system, blood is pumped by a heart through vessels, and does not normally fill body cavities. |
Invertebrates | an animal lacking a backbone, such as an arthropod, mollusk, annelid, coelenterate, etc. |
Levels of Organization | The biological levels of organization of living things arranged from the simplest to most complex are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere. |
Sessile | attached directly by its base without a stalk or peduncle. |
Medusa | a free-swimming sexual form of a coelenterate such as a jellyfish, typically having an umbrella-shaped body with stinging tentacles around the edge. In some species, medusae are a phase in the life cycle that alternates with a polypoid phase. |
Tissue | any of the distinct types of material of which animals or plants are made, consisting of specialized cells and their products. |
Vertebral Column | Also known as the backbone or spine, is a bony skeletal structure found in vertebrates. It is formed from individual bones called vertebrae (singular: vertebra), which houses the spinal canal, a cavity that encloses and protects the spinal cord. |
