About these flashcards

This flashcard set covers secondary school biology, focusing on the structure and function of cells and organisms, particularly in the context of Cnidaria. It explores key concepts like radial symmetry, the gastrovascular cavity, and specialized cells such as cnidocytes. The flashcards delve into the differentiation of forms like medusae and polyps, and the role of structures like tentacles and oral grooves. This set is ideal for students seeking to understand the intricate details of cellular biology and the unique adaptations of Cnidaria, providing a comprehensive overview of their biological processes and environmental interactions.

Animal Phylum consisting of organisms that have radial symmetry, a gastrovascular cavity and cnydocytes.

cnidocyte

Keyboard commands:

= turn,

= for-/backward,

= scroll

Stinging cell of cnidarians

nematocyst

Keyboard commands:

= turn,

= for-/backward,

Stinging capsule

Gastrocascular cavity

Keyboard commands:

= turn,

= for-/backward,

= scroll

A central digestive compartment with one opening as an anus and mouth.

Radial Symmetry

Keyboard commands:

= turn,

= for-/backward,

= scroll

A basic body plan where the organism can be devided into similar halves by passing a plane at any angle along a central axis.

polyp

= turn,

= for-/backward,

= scroll

floating, disc shaped form of cnydaria

tentacle

Keyboard commands:

= turn,

= for-/backward,

= scroll

A long thin soft organ near the mouth of the organism

gastrodermis

Keyboard commands:

= turn,

= for-/backward,

= scroll

outer cell layer

epidermis

Keyboard commands:

= turn,

inner cell layer

External stimulus

A detectable change in the environnement causing a response

protista or protoctistans

kingdom that comprises unicellular organisms organisms made of cells which have an obvious nucleous

light detector

light sensitive spot

eye spot

reg pigmented spot that shields the light detector from light coming from a certain direction

longitudinal

placed or running lenghtwise

to emerge

to appear or come out of something

oral groove

long deep cut in the surface of the protists (mouth)

food vacuole

organelle that forms by enclosing food particles with the cell membrane

contractile vacuole

organelle that rythmically pumps fluid out of the cell

cell colony

a group of uniform cells fused together

differentiation

structural or functional specialization

strand

a single piece of hair or string

motion

movement or way of moving

to burst

to break open suddenly or violently, often because there is too much preassure inside
