Chlorophyta/Chlorophytes (Green Algae) Flashcards
(16 cards)
What is unicellular?
Made up of one cell that carries out all the functions needed by the organism
What is multicellular?
An organism composed of many cells
What is isogamous?
A type of sexual reproduction in which gametes are similar in size, shape, and structure
What is oogamous?
A type of sexual reproduction where gametes differ in size and form
Is Chlamydomonas multicellular or unicellular?
unicellular
Is Chlamydomonas isogamous or oogamous?
Isogamous
How does Chlamydomonas reproduce?
They reproduce asexually by cell division (producing zoospores) and sexual reproduction through the fusion of gametes forming a diploid zygote which undergoes meiosis to produce a new haploid cell
Is Spirogyra unicellular or multicellular?
multicellular
Is Spirogyra isogamous or oogamous?
isogamous
How does Spirogyra reproduce?
They reproduce sexually through a process called conjugation and asexually through fragmentation
Is Ulva unicellular or multicellular?
unicellular
Is Ulva isogamous or oogamous?
isogamous
How does Ulva reproduce?
asexual reproduction often occurring through the release of quadriflagellate zoospores, while sexual reproduction involves the fusion of biflagellate gametes
Is Volvox unicellular or multicellular?
multicellular
Is Volvox isogamous or oogamous?
oogamous
How does Volvox reproduce?
reproduces both asexually and sexually; during favorable conditions, it primarily reproduces asexually by creating daughter colonies within the parent colony through specialized reproductive cells called gonidia, which eventually break free and grow into new Volvox colonies; when environmental conditions worsen, Volvox switches to sexual reproduction, producing male and female gametes that fuse to form a zygote, allowing the species to survive through unfavorable periods.
