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