- Which of the following statements about the haplodiplontic life cycle of land plants is/are TRUE? A During the sporophyte stage, sporangia house diploid mother cells that will eventually undergo meiosis. B Sperm develop from mitosis in the archegonium. C Spores grow by mitosis into mature haploid gametophytes. D The gametophytic stage begins with a diploid spore. EA and C are both true.The following structures are found on the underside of fern leaves and contain sporangia: a. sori b. rhizomes c. megaphylls d. microphyllsThere are two types of semaphyll - intrafloral semaphyll and extrafloral semaphyll. Intrafloral semaphyll is when it is from any four parts of the flowers, while it is extrafloral semaphyll if it comes from other parts outside of the flower-like stems, leaves, etc. Fill the table with the type of semaphyll and the plant part involved.
