Not illustrated. 1916 edition. Excerpt: ...is the asexual generation. Conclusion.--1. Compare the various structures of a flowering plant with those of the fern, moss, fungus, and alga. 2. Show that division of labor is greatest in the flowering plant. f. Physiological Development Refer back to your work on the function of the flower. At the time of fertilization, how many cells make up the young plant? What happens to it as it grows into an embryo? Is an embryo a more complex structure than an egg? Why? In the above forms is the development of this young plant in any way similar? (See charts or text figures.) General Conclusion.--1. What group of plants studied has the most complex structure? The greatest division of labor? 2. Is there any connection between the position of a plant in the plant kingdom and its complexity of structure? Explain. Problem 115: To compare reproduction in plants with that in animals. Materials.--Charts and models illustrating processes of fertilization and development in plants and animals. Method.--Compare, by means of charts, fertilization in several types of plants with that in some simple animal. Use models illustrating early development of amphioxus, fish, and frog. Observations.--How does fertilization take place in a flowering plant? In a fern? In a moss? In a very simple plant? By what means does the sperm cell get to the egg cell in each of the above cases? Is there any outside agency that helps in this? NOTE.--In animals, as in plants, two cells, the sperm and the egg, unite to form a fertilized egg. This cell will, under favorable conditions, develop into a new animal. In animals, which is the larger, sperm or egg cell? Which is the movable cell? Suppose an animal, as a fish, laid its eggs in the water, how might fertilization take place? NOTE.--The...
