Unformatted text preview: antheridial and archegonial heads. Under low power, locate the antheridia at the top of the antheridial head. Make a sketch to the right. Then, move to the 40X objective and focus on one antheridium. Observe the sterile jacket surrounding the sperm and/or sperm forming tissue. Note the sterile hairs interspersed between the antheridia. Make a second sketch. Are the sperm produced by mitosis or by meiosis? Are they haploid or diploid? Under low power, locate the archegonia at the top of the archegonial head. Make a sketch showing what you see. Find and focus on an archegonium using the 40X objective (hint: look for a long blue structure with a red cell in the centre). Locate the archegonia and identify the egg cell . Draw another sketch and label all structures observed. Is the egg haploid or diploid?...
