Experiment 19
PLANTS GROW FROM ROOTS, STEMS, AND LEAVES
MATERIAL: several low glass containers of different shapes, strawberry or violet runners , various kinds of tubers, carrot roots, bulbs, shoots of various plants.
- Prepare the different containers by filling them with water first and then as much of the above described material as you have been able to obtain.
- Whether it is a bulb or shoot, make certain that only the lower part is immersed in the water of the glass container.
- You may also put this material in soil instead of water.
- Observe what happens and write your observations every day.
Chart 15
ALTERNATION OF GENERATIONS
- This chart pictures the underside of the fern leaf, and the sporangium which opens and releases spores.
- The spores fall to the ground and germinate.
- The heart-shaped leaf, the prothallium, forms. In this little leaf, the male and female organs are formed.
- The female organs each produce one egg.
- The male organs produce spermatozoa.
- The spermatozoa join with the egg to form a new little plant.
Chart 16
LOVE IN PLANTS
- Flowers are dressed in beautiful colors and give off a sweet perfume, which attract insects.
- This perfume draws the insect inside the flower where it sucks the sweet nectar.
- Pollen adheres to the insect's hair is carried by the insect to another flower.
- When the pollen is deposited on the flower, it develops a tail which grows down and fertilizes the egg.
- The egg is then transformed into a seed.
Chart 17
GO MY CHILD
- This chart depicts a mother plant saying farewell to her child, a seed.
- The mother has provided the child with food to sustain his life until he is able to make his own.
- Sometimes the seed is covered with a fruit, which is a protection to the little seed, as well as a means to transport it far from the mother plant.
- The fruit represents the ovary enlarged.
- It is not useful to germination of a seed.
- Its purpose is to attract animals who will take the fruit as food, and the seeds will be carried far from the mother plant.
- Experiment: The seed and its parts:Take a bean seed, soak it over night or let it sprout. Using the nomenclature for the seed , take it apart and look at the seed and its parts.
Experiment 20
HOW PLANTS GROWN FROM SEEDS DEVELOP AND ARE NOURISHED
MATERIAL: several small plates, various kinds of seeds, cotton wadding, several glasses and water.
- Select different kinds of seeds and put them in water in the different glasses for 24 hours.
- Cover the plates with the cotton and then sprinkle the soaked seeds on the different plates.
- Keep all the plates well watered.
- Make a note of when they germinate and of how much they have gown each day.
- At a certain point, what happens? Why? Write you deductions.
Experiment 21
MONOCOTYLEDON AND DICOTYLEDON PLANTS
MATERIALS: a terrarium with soil, different seeds: bean, wheat, corn; a watering can with sprinkler and water, several glasses.
- Soak each variety of seed in a separate glass of water for 24 hours.
- Then remove them and sow in straight rows in the terrarium., identifying the different seeds by takes with labels.
- Water them immediately and always keep them moist, remembering that if seeds aren't kept moist they will die and not germinate.
- Observe what happens and make regular notations.
- The important thing for this experiment is to observe how the plant is formed when it sprouts.
