-
Animal Like protists lack .
Tissue
-
Body symmetry of eukaryotic cells
asymmeticrial, spherical
-
Osmoregulation in cells without walls
contractile vaculoes
-
Life cycles of animals are not as complicated as
plants
-
What is a Protist?
A eukaryote that is not a plant, fungus, and an animal
-
A monophyletic group is a common ancestor and all its descendants and an example are
Eukaryotes
-
What is not a monophyletic group
Protista (polyphyletic)
-
How are animals unique
have a nervous system
-
prokaryote engulfing a aerobic prokaryote
serial endosymbiotic theory
-
Not united by any unique features, or shared, derived traits
Kingdom Protista
-
First membrane bound organelle
Mitochondria
-
Life cycle very complex
Kingdom Protista
-
Animal Like Protists are similar to
Plant like protists
-
Eukaryotic cells contain
Membrane enclosed nucleus, Endomembrane System, Mitochondria for respiration, Cytoskeleton, Flagella, life cycles that include mitosis meosis and sex, multiple chromosomes
-
No body axis, Asymmetrical body plan, No plane of symmetry
animal - like protist
-
single celled protists increase surgace area by
flattening their bodies
-
Hypotonic solution
more water is coming into the cell
-
Hypertonic solution
more water is coming out of the cell (salty)
-
isotonic
equal amounts of water are coming in and our of the cell, marine enviroment
-
Osmoregulation is directly associated with
enviromental conditions
-
regulates osmoregulation found only in freshwater
contracticle vacoule
-
Thickend cell membranes that provide support and shape
pellicle
-
locomotion in animal-like protists
psedupods, flagella, cilia
-
ameoba uses blank to engulf prey called intracellular digestion
phagositosis
-
Macronucleus
50 copies of genome, control everyday functions, asexual reporduction by binary fission
-
micronucleus
active in meiosis, produces genetic variation during conjugation
-
Protist Plasmodium causes
malaria
-
New characteristics in Sponges
multicelluarity, epidermal epithelia, collagen present, spermatozoa. specilaization in cells
-
Reproduction in sponges
budding, gemmules, reaggregation
-
3 unique body plans of sponges
ascon, sycon, leucon
-
Choanocyte cells line spongocoel of a spong and
capture food particles and is where digestion occurs
-
Sponges gas exchange and exxcretion occurs by
diffusion
-
Spiricals in sponges can be made of
calciium carbonate, silicon, collagen-like protein called spongin
-
sponges are composed of which provide support
spiricals
-
Spiricals of glass are
flexiable!
-
largest type of body type of a sponge
Leucon
