Q

What would happen to an amoeba placed in salt water

A

The amoeba would shrink since the solution outside is higher than inside the organism

Q

How did Euglena gain the ability to photosynthesize

A

It is hypothesized that an ancestor engulfed photosynthetic cyanobacteria and formed a symbiotic relationship with the cyanobacteria providing a food source and the euglena providing protection

Q

What important transition do volvox illustrate as a step towards multicellular life but are not considered multicellular

A

cell differentiation through the division of labor among cells by limiting reproduction to its sex cells within the colony but each organism is still independent so not fully multicellular

Q

What are some areas in the body that have cilia and how does their function differ from the cilia of a paramecium

A

Cilia are found in the lining of our gut and beat in a rhythmic way like ciliate organisms but they function to move materials like dirt, mucus, and nutrients rather than propelling the cell

Q

what does a paramecium in conjugation look like and define it

A

Conjugation is when they split in half long ways and is when one bacteria transfers genetic material to another through direct contact

Q

What is binary fission look like and define it

A

binary fission is when they elongate until they split and is asexual reproduction by a separation of the body into two new bodies

Q

How do paramecium reverse when they bump into something

A

After they hit an object the change in action potential open calcium channels in the membrane causing depolarization and a reversal of cilia direction

Q

What is the function of the two nuclei in paramecium

A

The macronucleus controls non reproductive functions while the micronucleus contains genetic information for sexual reproduction

19
Q

How do stenor use their cilia

A

They use them for both locomotion and feeding

20
Q

How does water go through a scyon

A

the water enters the incurrent cana to the prosopyle to the radial canal then to the apopyle to the spongocoel then the osculum

21
Q

What is the function of choanocytes

A

Flagellated cells that create water current and remove particles from water

22
Q

What is the function of pinacocytes

A

Epithelial cells

23
Q

What is the function of porocytes

A

Tube cell that allows water into the sponge

24
Q

What is the function of spicules

A

Stiff skeleton of the sponge

25
Q

Describe sexual and asexual reproduction in proifera

A

Sponges asexually reproduce via budding and sexually reproduce when they release sperm into the water that are taken up by other sponges to fertilize eggs until they develop into spongocoel before being released and floating around until they settle

26
Q

What does it mean that cnidarians are diploblastic

A

Their bodies are formed from two tissue types; ectoderm which becomes the body covering and endoderm which becomes the gut

27
Q

What type of symmetry to Cnidaria have

A

Radial symmetry

28
Q

What is a major synapomorphy of Cnidaria. Describe its function

A

Nematocysts which are stinging cells used for defense and hunting

29
Q

What are the two types of Cnidaria

A

Medusa: motile reproductive form and poly: sessile form

30
Q

What gives Cnidaria their body structure

A

Hydrostatic skeleton which can be moved by muscles

31
Q

How do hydra move

A

sliding via tentacles and feet, and somesaulting

32
Q

How do hydra reproduce

A

Asexually by budding off or sexually with the gonads on the sides of their bodies

33
Q

What are the advantages of obelia having a medusa stage

A

allows for mobile offspring to find more favorable conditions and greater opportunity for genetic mixing

34
Q

What structure differentiates hydromedusa and a true jellyfish

A

Hydromedusa have a velum which aids in swimming

35
Q

What is a similarity and difference between a ctenophore and cnidarian

A

They both have radial symmetry while ctenophores lack nematocysts

36
Q

Why might ctenophores resemble jellyfish

A

convergent evolution

37
Q

What is the difference between moneciuos and dioecious

A

Monoecious individuals have both testes and ovaries while diecious individuals need someone else to reproduce

38
Q

Are platyhelminthes, nematoda, and rotifera acoelomates or pseudomates

A

platyhelminthes are acoelomates while nematoda and rotifera are pseudocoelomates

39
Q

How do flatworms move

A

They glide on mucus secreted from its ciliated epidermis using longitudional and circular muscles

40
Q

How do flatworms feed

A

The ventral mouth extends from the pharyngeal sheath. The pharynx sucks and ingests food that then goes to the anterior trunk of the intestine

41
Q

What structures do tapeworms have that help them live in the intestines

A

Scolex which has suckers to hold on during intestinal muscle movement and tegument which are specialized for living in hostile environments

42
Q

What type of muscle do vinegar eels have and why did the sand grains allow them to change their swimming behavior

A

Longitudinal muscles and the grains allow them to push off something and move around

43
Q

How do rotifera attach to things and is it free swimming

A

Their foot has a pedal gland that secretes a cement for clinging to objects and is free swimming

44
Q

How do gastrotricha differ from rotifera

A

they glide along a substratum using cilia
