Silurian and Devonian Flashcards
Is trapped on the inner surface of the mucus net the lines the pharyngeal cavity of early chordates.
Food
The ray-finned fish perfected this unique form of feeding to capture their pray.
Suction
Microtubular structure that directs cell division in plants.
Phragmoplast
Parasite that lives on the surface of its host is what type of parasite?
Ectoparasite
This pathway for moving materials in plants uses the cell wall.
Apoplastic
This part of the vertebrate skeleton includes the two sets of paired fins.
Appendicular
The sheet of mucus covers the inner surface of the pharyngeal cavity of chordates is produced by this structure.
Endostyle
– Early chordates, like the lancelet, were this type of feeder.
Filter
There isn’t agreement…. Chrodate subclass called?
Craniata
The evolution of the jaw was originally an enhancement to this function.
Respiration
terrestrial plants evolve from this type of algae.
Green
The spine of a shark’s scale points in this direction.
Backwards
Plant spores are produced inside this structure.
Sporangium
In non-vascular plants these assist a sperm in getting to the egg.
Flagella
The composition of their skeleton and the use of this substance help the Chondrichthyes achieve neutral bouncy.
Oils
What an archegonium produces.
Eggs
Cellulose is a polymer of which sugar molecule?
Glucose
The sarcopterygian fishes are commonly called the ____ finned fish.
Lobe
The waterproof layer of a leaf.
Cuticle
The cells that swell to close the opening and shrink to allow air to pass through to the photosynthic tissue.
Guard
These plant tissues are missing in mosses.
Vascular
This type of skeleton is the least dense of the skeletons found in fish.
Cartilidge
Chordates’ silts that help separate food from ingested water prior to passing the food into the digestive system.
Pharyngeal
Number of flagella on the moss sperm cell.
