gamete: a mature haploid male or female germ cell which is able to unite with another of the opposite sex in sexual reproduction to form a zygote.

spore:a minutes typically one-felled, reproductive unit capable of giving rise to a new individual without sexual fusion, characteristic of lower plants, fungi, and protozoans.

algae: a simple, nonflowering, and typically aquatic plants of a large group that includes the seaweeds and many single-celled forms. algae contains chlorophyll but lack true stems, roots, leaves, and vascular tissue.

fungi:any group of spore-producing organisms feeding on organic matter, including molds, yeast, mushrooms, and toadstools.

lichen:a simple slow-growing plant that typically forms a low-crusty,leaflike, or branching growth on rocks, walls, and trees.

decomposer: an organism, especially a soil bacterium, fungus, or invertebrate, that decomposes organic material.

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.

blue is scattered more than other colors because it travels as shorter, smaller waves. this is why we see a blue sky most of the time.
