HOW ROOTS MOVE IN THE DIRECTION OF THE WATER
- Since water is essential to the growth of the plant and its basic survival, roots will seek water out in the soil if it is not immediately.
Experiment 2
ROOT HAIRS
MATERIALS:
A small clay flower pot, some radish seeds, water a drinking glass, two small transparent bowls.
- Put some radish seeds in a glass and fill it half way with water.
- Place the flower pot in one of the bowls which is then filled with water.
- Place the flower pot in one of these bowls which is then filled with water.
- After 24 hours, remove both the pot and the seeds from the water.
- Inver the flower pot and try to make the seeds adhere to the bottom of the pot.
- Then return the up-side-down pot to the bowl of water so that the seeds are out of the water.
- Use the other transparent bowl up-side-down as a cover.
- Keep the whole thing in the light.
- Observe what happens every day and write down your observations.
Experiment 3
FORMATION OF ROOTS
MATERIALS: A jar with a rather narrow mouth, water, some twigs from a plant.
- Fill the jar with water and immerse the twigs.
- Observe the plants each day adding water if necessary.
- Write your observations.
Experiment 4
ACIDIC REACTION OF ROOT HAIRS
MATERIALS: A jar containing germinated radish seeds, blue litmus
paper.
- Put the litmus paper on the sucking hairs of the plant.
- Observe what happens and write your observations.
Experiment 5
DIRECTION OF THE ROOTS
MATERIALS: A glass, ink-blotter paper, black construction paper, a rubber band, sand, bean seeds, water.
- Cut the ink blotter paper to fit around the inside of the glass.
- Place the bean seeds between the blotter paper and the sides of the glass making sure they are positioned differently.
- Then fill the glass with sand and wet the sand.
- Cut the black construction paper large enough to wrap around the outside of the glass, holding it in place with a rubber band.
- The sand must be kept wet.
- Do the same using other seeds.
- Observe your glass every day.
- Observe what happens and write your observations.
Chart 4
ROOTS OVERCOME ANY OBSTACLE
- So strong is that need for the water and the minerals, the plant will not allow anything to be an obstacle.
- Roots will grow around large objects in order to obtain what it basically needs to survive.
Chart 5
GIVE DRINK TO THE THIRSTY
- By observing the leaves of a plant above the ground, we can understand the root system.
- The width of the leaf system corresponds to the root expansion below the ground.
- If the plant is long and thin, so is its root system, and so forth.
