Which of the following is NOT a caharacteristic of all seed plants?
1. a sporic life cycle
2. cell walls containing cellulose
3. life cycle is dominant in the sporophyte phase
4. reproductive organs found in flowers
5.nearlly all are photo-autotrophic
Which of the following is NOT a characteristic of the gametophyte stage of the flowering plant?
-The gametophyte is diploid
-Male and female gametophytes are separate from one another
-The gametophyte is haploid
-The gametophyte is dependent on the sporophyte for a specific amount of time
-The gametophyte is a gamete producing structure
The classification of the seed plants has varied. If a person groups all seed plants together in one large Division Spermatophyta, then they have two classes—the class with naked seeds and the class , plants with carpels. On the other hand, many people (and this book) use four divisions, not one. List the three divisions of “gymnosperms” and the one division of flowering plants.
