Bio II Exam 4 UCF Yeargain Questions
With Complete Answers
Plesiomorphic characters with prokaryotes - ANSWER had metabolism,
plasma membranes, and ribosomes
Synapomorphic characters with plants - ANSWER had sexual reproduction
and meiosis
Synapomorphic characters with fungus - ANSWER were heterotrophs,
consuming living or dead organisms
Autapomorphic characters - ANSWER new, derived characters
not present in LUCA, prokaryotes or protists, fungi or plants
Motile (can move)- can be for only a part of life cycle or all
Complex tissue with specialized types
Diplontic life cycle
Embryonic developmental stages
What does it mean when an organism has embryonic developmental
stages? - ANSWER they have a fixed body plan
What are complex tissue structures in animals associated with? - ANSWER
finding and processing food, and example being sensory organs
What differentiates animal cells and tissues from plant tissues and fungal
tissues? - ANSWER No cell wall
Gap junctions for communication between cells
Sometimes these cells/tissues are embedded in extracellular matrix, EX:
bone matrix
Vertebrates have connective tissue for structural support
, Epithelial tissue covers the external body and internal organs
Connective tissue - ANSWER includes both non-living and living cells, EX:
blood and blood vessels, cartilage, ligament, bone, tendon, fat
Supports body structure
Not all animals have connective tissue
Epithelial tissue - ANSWER covers and protects internal organs and
external body structures
Muscle tissue - ANSWER facilitates movement, skeletal, cardiac and
smooth
Not all animals have TRUE muscle tissues
Nervous tissue - ANSWER receive and transmit electrical impulses,
neurons and nerve cells
Not all animals have nervous tissue
What are the purposes of specialized systems in animals? EX? - ANSWER
for obtaining food and avoiding predators
finding a sexual partner (drive for reproduction)
Sensing environment and responding to changes in it
Motility (what makes them move)
EX's: digestive system, sensory system, muscular system
What is the animal kingdom divided up into? - ANSWER 5 monophyletic
clades: porifera, placazoa, cnidaria, ctenophora, bilateria
Porifera - ANSWER sponges; sessile animals that lack true tissues;
suspension feeders, trap particles that pass through the interal channels of
their bodies
Placazoa - ANSWER parasitic amoeba-like animal
Ctenophores - ANSWER comb jellies, have 8 rows of cilia and move by
beating the cilia, captures small plankton with two tentacles that discharge
adhesive material, tentacles then bring food to mouth
Cnidaria - ANSWER jellyfish, corals, sea anemones
