Zoology Chapters 1-5
<p>The variety and variability of living organisms and the ecological complexes in which they occur</p> <!--EndFragment-->
-Sexually – reproducing forms: an ongoing group of interbreeding natural population reproductively isolated from all other groups
-Asexually – group of organisms similar to each other but recognizable different from other groups.
the study of life’s geographic distribution
Variety in a given area as measured by the different kinds of species
The maximum number of living organisms that an environment can support
- A measure of the relative breeding success of an individual or genotype in a given population at a given time
The naming and classifying of organisms
The differences that occur between members of the same species
A permanent change in the genetic makeup (DNA) of an animal
– No symmetry
A cross section, dividing an animal into anterior and posterior parts
Body plan in which only one midsagittal section well result in two mirror images.
A plane of bisection along an animal’s longitudinal axis to make right and left half.
has a Circle symmetry, like a spokes on a wheel
A plane of bisection that divides an animal into dorsal and ventral portions
- Dorsal: Back of an animal. Ventral: Front of an animal
– Balanced state. Conditions of an internal environment of animal is at equilibrium
Anterior: Torso to head. Posterior: Torso to legs.
Auto: Makes it’s own food photosynthesis,
Hetero: Finds its food. From inorganic or organic elements within the environment
Proximal – Closer to the middle of body, Distal – Farther away from the middle
medial/lateral – Lateral:
Away from midline. Medial: Toward the midline
– Eats only plants
Eats both Plants and Animals
Forms food vacuoles, cytoplasmic extensions of amoebas used in feeding.
Luciferin in presence of ATP and oxygen. Makes glow.
Tails/Hair like cell process that is usually used for locomotion
The Photoreceptor in Euglena and other protist
Endo- process in which material passes through the plasma membrane
Exco- Where material from the cell passes through the plasma membrane.
A hair like defensive device expelled from the pellicle of certain ciliates
hair like extensions on certain cells.
Attached to a surface
Middle gelatinous layer in a sponge.
the open seal
exchange in res[oratory gases though the body surface.
The pores in which water pours into.
the top of the sponge
The cell that houses the stinging cell of a jellyfish or other cnidarian
The gel like layer of a jellyfish that allows buoyancy
the attached, asexual stage of a cnidarian
A stinging apparatus of cnidarians
– Epi- The outer layer of cell, Ectoderm- the inner layer of the cell.
jellyfishlike shape and are the sexual stage in cniardian life cycle
Nervous system of cnidarians consisting of a diffuse network of nerve cells
to transport nutrient and discharge gametes
Colonial reef-building all in shallow waters –depends on zooxanthellae
Coral diseases can wipe out entire colonies
Allows animals to swim against the current
Gas exchange and digestion
Both parties of organisms benefit from each other
Little eyes on the nervous system
Attached to the surface
