Seed plants often have a relationship with a pollinator which tends to increase their chances of producing offspring.Seed plants are typically larger,vascular,and contain a wider variety of structural adaptations that enable them to adapt to a variety of conditions.Seeds themselves are often more successful in a wider variety of environments than spores.

As plants invaded the land,all of the following were true EXCEPT


A) there was a greater availability of light for photosynthesis.
B) there was a greater concentration of carbon dioxide available in the atmosphere.
C) there was an increased threat of desiccation of unprotected cells.
D) there was an increased threat from predation by animals.

It is possible to take a mature fern frond and rub the circular brown growths on the lower surface over a wet plug of peat moss.Soon small heart-shaped green structures grow on the nutritious peat moss plugs.What has happened?


A) Eggs and sperm released from the underside of the fern frond united on the peat plug and grew into sporophyte prothalli.
B) Spores released from the underside of the frond germinated on the peat plug and formed the gametophyte called a prothallus.
C) Spores released from the underside of the fern frond germinated on the peat plug and formed sporophyte rhizomes that give rise to many indusium.
D) Gametes released from the underside of the fern frond germinated on the peat plug and formed a sporophyte structure called an archegonium.
