Term
Haploid Gametophyte
.still dominant in?
produces?
.egg is__ inside____ and remains?
._____provides all_____ to _______ |
|
Definition
still dominant in non vascular embryophtes
.porduces egg and sperm gametes
egg si fertilized inside gametangium (archegonium) and remains on gametophyte after fertilization
gametophyte provides all nutrient to dependent saprophyte |

Definition
.closets relative of seed splints
.like spikemosses Quillworts, and Clubmosses, the Sporophyte dominates the life cycle while the gametophytes are usually much smaller and shorter-lived
.ferns usually produce spores on their leaves or have specialized leaves devoted entirely to spore production |
