Defining features of animals
Animals are multicellular and eat other organisms for energy.
Nutritional habits of animals
Animals eat other organisms.
How sponges feed
Sponges collect nutrients from water using choanocytes.
Symmetry in jellyfish and corals
They exhibit radial symmetry.
Characteristic of diploblastic animals
They have two body layers and one opening.
Key feature of triploblastic animals
They have three embryonic layers.
Benefit of bilateral symmetry
It helps in effective movement and hunting.
Deuterostomes in chordates
The blastula becomes the anus.
Notochord function
It supports the spinal column.
Common trait of echinoderms
They have radial symmetry as adults.
Function of tube feet in echinoderms
They help with movement and grabbing objects.
Groups of vertebrates
Lob-finned fish, ray-finned fish, and tetrapods.
What is a blastula?
A hollow ball of cells in early development.
Difference between arthropods and deuterostomes
In arthropods, the mouth forms first.
Function of lophophore
It is used for feeding.
Examples of lophotrochozoans
Mollusks, annelids, and flatworms.
Growth in ecdysozoans
They grow by shedding their exoskeleton.
Roundworms vs. segmented worms
Roundworms lack segmentation; segmented worms are divided into segments.
What are tardigrades?
Microscopic animals that survive extreme conditions.
Characteristics of vertebrates
They have a central nervous system and an internal skeleton.
Amniotes definition
They have eggs that allow development on land.
Function of mammary glands
They provide milk for offspring.
Marsupials' care for young
They carry young in a pouch.
Innovation of jawed vertebrates
Jaws provided a feeding advantage.
Function of pharyngeal slits
They act as gills for gas exchange.
Groups of mammals
Prototherians (egg-laying), marsupials (pouch-care), eutherians (live birth).
Characteristic of annelids
They have segmented bodies.
Gastropods in mollusks
They include snails.
Clade with jointed appendages
Arthropods.
Types of arthropods
Crustaceans, hexapods, myriapods, and chelicerates.
Lobe-finned fish significance
They are ancestors of land vertebrates.
Amniotic eggs vs. regular eggs
Amniotic eggs have protective shells.
Echinoderms' symmetry
They have radial symmetry as adults.
Hagfishes and lampreys' feature
They lack jaws.
Jointed limbs in arthropods
They help with movement and hunting.
Blastula definition
It is an early embryonic structure.
Central nervous system in chordates
It is a dorsal, hollow nerve cord.
Reptiles' common feature
All have an amniotic egg.
Postanal tail function
It aids in movement.
Benefits of internal skeletons
They provide support and organ protection.
Examples of prototherian mammals
The platypus.
