Alternation of Generations

What plant groups that we've studied are still dependent on water for reproduction?
Algae, moss and ferns
Name 3 of five structures that land plants developed to deal with the challenges of life on land.
Name 3 of five structures that land plants developed to deal with the challenges of life on land.
Cuticle, Vascular tissue, seed coat, pollen grain, flowers/fruits,
What is the function of xylem?
What is the function of xylem?
To transport water AND nutrients
What is the function of the cuticle?
What is the function of the cuticle?
To prevent water loss
What are the rhizoids of moss responsible for?
What are the rhizoids of moss responsible for?
Anchoring the moss to the surface
Why are many algae "leaves" only 2 cells thick?
Why are many algae "leaves" only 2 cells thick?
Because algae lack vascular tissue, they rely on contact with water to get water, nutrients and to get rid of waste.
What are different forms of chlorophylls and accessory pigments for?
What are different forms of chlorophylls and accessory pigments for?
Structures that capture the energy of light, in many different wavelengths depending on the needs of the plant.
True or False. Ferns have true roots, stems and leaves.
True or False. Ferns have true roots, stems and leaves.
True. Since ferns have vascular tissue, unlike moss and algae.
Name the 2 plant groups which produce pollen grains
Name the 2 plant groups which produce pollen grains
Gymnosperms and Angiosperms
What does the phloem transport, and which direction(s) does it transport?
What does the phloem transport, and which direction(s) does it transport?
Sugars (products of photosynthesis). Up and down to whichever part of the plant needs it.
Name 3 ways that we can tell a monocotyledon from a dicotyledon.
Name 3 ways that we can tell a monocotyledon from a dicotyledon.
Leaves, roots, stems, flowers, and growth
Name the gametophyte structures in gymnosperms and angiosperms
Name the gametophyte structures in gymnosperms and angiosperms
Ovules and pollen grains
Is the spore haploid or diploid?
Is the spore haploid or diploid?
Haploid
Is the green part of the moss gametophyte or sporophyte?
Is the green part of the moss gametophyte or sporophyte?
Gametophyte
The process that produces haploid spores from a diploid sporophyte is called ________.
The process that produces haploid spores from a diploid sporophyte is called ________.
Meiosis
Name the plant groups we have studied that have swimming gametes
Name the plant groups we have studied that have swimming gametes
Algae, moss, and ferns
Explain why the cotyledon of flowering plants are triploid, while the true leaves are diploid. (in detail!)
Explain why the cotyledon of flowering plants are triploid, while the true leaves are diploid. (in detail!)
The cotyledon comes from the endosperm (3N), which is created from fusing a sperm cell (N) with two polar nuclei (N and N).. This makes 3 nuclei in all, for a triploid structure. The true leaves are derived from the embryo, which is formed from the fusion of egg and sperm (2N).
Is the zygote haploid or diploid?
Is the zygote haploid or diploid?
Diploid
What does the archegonium produce?
What does the archegonium produce?
Eggs
Is the prothallus of the fern haploid or diploid? Multicellular or unicellular?
Is the prothallus of the fern haploid or diploid? Multicellular or unicellular?
Haploid; multicellular
Explain how flowers increase the success rate of a pollen reaching its target.
Explain how flowers increase the success rate of a pollen reaching its target.
They provide a nectar reward for animals, who then carry the pollen to another flower.
Explain how pollen is an adaptation to life on land.
Explain how pollen is an adaptation to life on land.
Pollen allows sperm (gametes) to be carried to its target by wind rather than water.
