1.Name and describe the life cycle of plants.
The plant life cycle is consisted of two parts: the gametophyte phase where it produces gametes by mitosis and the sporophyte phase which produces spores by meiosis 2.Contrast the life cycle of plants to that of animals:

Typical life cycle: alteration of generation (plants), diploid (animals) Resulting structure from meiosis: spores-plants, gametes-animals Occurrence of mitosis: gamete production-plants, zygote to individual-animals 3.Compare mosses and ferns by completing the following table

Dominant GenerationVascular TissueFlagellated SpermMethod of Offspring Dispersal MossGametophyteNoYesWindblown spore
4.FernSporpophyteYesYesWindblown spore

5.Why do some biologists call the novascular plants the amphibians of the plant kingdom? non vascular plants need an aquatic environment to live in, in order to reproduce. 6.Are ferns better adapted to land environements than mosses? Yes, they have vascular tisses

7.How do both mosses and ferns disperse offspring?
Windblown spores
8.How is the gametophyte in ferns similar to that of mosses? They produce flagellated sperm
How is it different (aside from appearance)?
The gametophyte generation is dominant in mosses and the sporophyte generation is dominant in ferns 9.Why is it beneficial to have the sporophyte generation dominant in vascular plants? They have vascular tissues

10.Compare and contrast moss and fern sporophyte.
The moss sporophyte is dependent on the gametophyte. The fern sporophyte is dependent on the gametophyte which is the mosses dominant generation. 1.What is the major difference between prokaryotic and eukaryotic cells? Prokaryotes lack a nucleus. 2.What chemical associated with the cell wall gives Gram-positive bacteria their final color? Peptidoglycan 3.

a.In what ways are cyanobacteria like algae and land plants? They go through the photosynthesis b.How are they different? They are prokaryotes
4.How can...
