The large tree we observe is the gametophyte stage while the sporophyte stage is much smaller and contained in flowers.

The large tree we observe is the gametophyte stage while the sporophyte stage is much smaller and contained in cones.

The large tree we observe is the sporophyte stage while the gametophyte stage is much smaller and contained in cones.

The gametophyte is diploid, relying on water to disperse the spores.

The gametophyte produces seeds that rely on animals for dispersal.

The gametophyte relies on the sporophyte for sugars produced by photosynthesis.

The gametophyte relies on water for reproduction, limiting their habitat range.

axillary buds.

shoot apical meristems.

floral meristems.

It reduces the need for water during fertilization.

It enables the production and protection of multiple gametes.

It allows plants to reproduce only through asexual means.

It eliminates the need for a sporophyte stage.

The discarded apple exposes the avocados to ethylene which instigated ripening.

Opening the back of the truck exposed the avocados to oxygen, which accelerated their ripening.

The discarded apple exposes the avocados to gibberellic acid which instigated ripening.

Opening the back of the truck exposed the avocados to carbon monoxide, which accelerated their ripening.

Both have reduced multicellular gametophyte stages that are totally dependent on the sporophyte stage.

Both have a dominant sporophyte stage.

Both produce a male gametophyte in the form of pollen.

Both rely on insects or birds to ensure pollen is transported to the female gametophyte.
