Ovules and pollen grains
1) More direct sunlight 2) less competition and predation (at the time)
Cuticle, Vascular tissue, seed coat, pollen grain, flowers/fruits,
Eggs
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.
Algae, moss, and ferns
They provide a nectar reward for animals, who then carry the pollen to another flower.
Algae, moss and ferns
Diploid
Eukaryotic (membrane bound organelles and nucleus)
Alternation of Generations
Sugars (products of photosynthesis). Up and down to whichever part of the plant needs it.
Gametophyte
Haploid
Leaves, roots, stems, flowers, and growth
Haploid; multicellular
Meiosis
Gymnosperms and Angiosperms
Pollen allows sperm (gametes) to be carried to its target by wind rather than water.
True. Since ferns have vascular tissue, unlike moss and algae.
To transport water AND nutrients
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).
What does the archegonium produce?
What are the rhizoids of moss responsible for?
Is the spore haploid or diploid?
Name the 2 plant groups which produce pollen grains

Are plants eukaryotic or prokaryotic?
What are different forms of chlorophylls and accessory pigments for?
Is the green part of the moss gametophyte or sporophyte?
What is the function of the cuticle?
The process that produces haploid spores from a diploid sporophyte is called ________.
Explain how flowers increase the success rate of a pollen reaching its target.
What were the advantages of plants that colonized the land?
Name the gametophyte structures in gymnosperms and angiosperms
Name 3 of five structures that land plants developed to deal with the challenges of life on land.
What is the term to describe the life cycle of plants, which alternates between a haploid and diploid generation?
Explain why the cotyledon of flowering plants are triploid, while the true leaves are diploid. (in detail!)
Why are many algae "leaves" only 2 cells thick?
What is the function of xylem?
True or False. Ferns have true roots, stems and leaves.
Name 3 ways that we can tell a monocotyledon from a dicotyledon.

Explain how pollen is an adaptation to life on land.
What does the phloem transport, and which direction(s) does it transport?
Name the plant groups we have studied that have swimming gametes
