seedless-vascular plants. Well developed roots and rigid stems. Endosperm will develop only in ovules containing a fertilized egg. As the plants died, they fell into stagnant wetlands and didn't decay completely; their remains formed thick organic deposits called peat.Haploid megaspores develop into haploid female gametophytes, which then produce eggs. The archegonium is also where the egg is fertilized once the sperm from the antheridium swims through water to The seedless vascular plants can be divided into three groups: Lycophyta (lycophytes)...Seedless vascular plants developed three important things Spores develop into haploid gametophytes. Fern gametophytes are tiny, heart-shaped and short-lived. They only live a few days but if an egg was successfully fertilized on the gametophyte, soon a sporophyte begins to grow on top of...In seedless plants, a fertilized egg will develop into _____. gametes. a fruit. Fertilization would probably be more difficult. Unless its body parts were strengthened, such a "tree" would probably flop over.embryo. fertilized eggs develop into multicellular embryos. gametangia. the origins of plants as a general rule. strobilus. composed of several stalked umbrella like structures, each of which bears five to ten sporangia in a circle around a common axis.

Parthenogenesis (development of an embryo without fertilization) occurs in some organisms. There are some species of rotifers in which a male has never been discovered. I've also heard that turkey eggs will sometimes develop into an embryo without fertilization, though, through nondisjunction...Seedless oranges and seedless grapes are the result of cultivation of naturally occurring seedless plants. The Thompson has a genetic abnormality that causes the seeds to arrest development. Biologists can fuse a new gene into a fruit plant that tells the plant to produce a growth hormone.The fertilized egg starts growing fast, dividing into many cells. It leaves the fallopian tube and enters the uterus 3 to 4 days after fertilization. In rare cases, the fertilized egg attaches to the fallopian tube. This is called a tubal pregnancy or ectopic pregnancy and is a danger to the mother.In seedless plants, a fertilized egg will develop into _____. a sporophyte. What evolutionary development allowed plants to grow tall? lignified vascular tissue. During the Carboniferous period, forests consisting mainly of _____ produced vast quantities of organic matter, which was buried and...

Most seedless plants live in damp and shady habitats. Certain types of mosses, called PEAT MOSSES, grow in vast expanses of wetlands in the northern parts of the world. This produces the sex cells. Fertilized by male sperm, the female egg of the prothallus develops into a new adult plant.The young plant that develops from the fertilized egg is called the embryo. This zygote develops into an embryo, that finally grows into a mature diploid sporophyte which can again release spores. Some seedless grape varieties may develop tiny seeds/vestigial seeds or seed remnants/traces...30. The union of egg and sperm is called what? 31. In flowering plants, what structure allows sperm to travel to egg? 32. The transfer of pollen from the anther to the stigma is called pollination . 33. Why can't you go to a garden store and buy fern seeds?Plant eggs are the exception because they do not need to contain nutritive materials; the developing sporophyte embryo is nourished until self-supporting by the plant on which it is formed. Upon maturation, the neck opens to allow sperm cells to swim into the archegonium and fertilize the egg.Non-vascular seedless plants (Bryophytes) were the first plants to live on land. Examples include mosses, hornworts and liverworts. When an egg is fertilized, it becomes a diploid zygote that matures into a sporophyte on the gametophyte plant.
In seedless vegetation, a fertilized egg will develop into _____. in seedless crops, a fertilized egg will develop into _____. a fruit a gametophyte spores gametes a sporophyte
