What is alternation of Generation?
When the life cycle of an organisms alternates between diploid and haploid generations
What is asexual reproduction?
When a portion of a plant develops into a seperate, new plant
what is diploid generations?
When you look at a tree or plant, you are typically looking at the diploid generation
What is haploid generations?
The majority of haploid generation lives within tissue of the diploid plant
What is Sporophyte?
Diploid generation of a plant that produces spores
What is diploid cells?
Contain both sets of Chromosomes (DNA)
What is on advantage Asexual reproduction has?
Only takes one organisms to reproduce
What is Haploid?
Contain only one set of chromosomes (DNA)
What is Gametophyte?
Haploid generation of a plant that produces gametes (sperm and egg cells)
What is pollen grains?
Forms from tissue in male reproductive structure of seed plants
What is pollination?
When pollen grains land on a female reproductive structure of a plant that is the same species
Diploid generation is the green, leafy plant you see in what?
forests
After fertilization occurs it forms a zygote which develops into an what?
Embryo
What is a Stamen?
Male reproduction organ of the flower
What s Ovule?
The female reproductive structure of a seed plant where the egg develops.
Cell divison occurs in reproductive structure of what plant?
diploid
Haploid and diploid cells contain both what?
sperm and egg cells
Cell division occurs in reproductive structures of what?
Diploid plant
After pollination, sperm from the pollen grain enters the ovule and what occurs?
fertilization
What carries pollen grains to female reproductive structures?
Wind, Water, Animals, Gravity
What trees are in the Gymnosperms?
Pines,Firs, and Red wood trees
Male cones contain pollen grains, female cones produce what?
eggs
What are thw 5 steps of the flower?
Stamen
Pistil
stigma
style
ovary
What are the 9 steps of the life cycle of an Angiosperm?
1) Haploid pollen grains travel from the anther to the stigma,2) Pollination occurs,3) a pollen tube grows from the stigma down to the ovary,4) Sperm develop from haploid cell in pollen tube,5) When pollen tube enters ovule, fertilization occurs,6) Zygote develops into an embryo,7) Embryo joins with ovule to become a seed,8) Fruits develops from ovary, and finally 9) Seeds grow into new plants and the life cycle repeats
Some seeds can pass through an animals what system?
digestive
