Sporophyte
What is the difference between rough and smooth endoplasmic reticulums?
Rough ER has ribosomes attached
Prokaryotes and eukaryotes share three similar structures. A cell membrane, cytoplasm, and _____________.
Ribosomes
Label two of the four important events in the history of land plants.
Emergence out of water (land plants)

Emergence of flowers
Which of these green algae doesn't undergo alternation of generations?
Chlamydomonas, Spirogyra or Ulva?
Spirogyra: It reproduces asexually via fragmentation and sexually by conjugation.
Does not form gametes, thus no alternation of generations.
Gametophytes produce gametes via ____________.
Sporophytes produce spores via ____________.
Fill in the blanks with meiosis and/or mitosis.
Gametophytes: mitosis (1N to 1N)
Sporophytes: meiosis (2N to 1N)
