differentiate between the sporophytes of liverworts, hornwords, and mosses?

Answer 1

1) Liverwort sporophyte--The sporophyte body comprises a foot, long stalk, called a seta, and a spherical or ellipsoidal capsule the basal part , the foot is embedded with in the thallus. Within the capsule, cells divide to produce elater cells and spore-producing cells that will undergo meiosis to form haploid spores, upon which the cycle can start again.

2) sporophyte of hornworts ( not hornwords)-At the bottom of the sporophyte (closest to the interior of the gametophyte), is a foot. This is a globular group of cells that receives nutrients from the parent gametophyte, on which the sporophyte will spend its entire existence. In the middle of the sporophyte (just above the foot), is a meristem that will continue to divide and produce new cells for the third region. This third region is the capsule. Both the central and surface cells of the capsule are sterile, but between them is a layer of cells that will divide to produce pseudo-elaters and spores. These are released from the capsule when it splits lengthwise from the tip.

3) Sporophyte of Moss--The sporophyte body comprises a foot which is embedded in the gametophyte;long stalk, called a seta, and a capsule capped by a cap called the operculum. The capsule and operculum are in turn sheathed by a haploid calyptra which is the remains of the archegonial venter. The calyptra usually falls off when the capsule is mature. Within the capsule, spore-producing cells undergo meiosis to form haploid spores, upon which the cycle can start again. The mouth of the capsule is usually ringed by a set of teeth called peristome. This may be absent in some mosses.

Answer 2

Saprophrites live off dead/decaying organisms
And I 4got the rest. It's been a few weeks since I actually showed up for science class.
