Plant Water Absorption Experiment

The video tutorial, led by Laura, demonstrates a simple celery and food coloring experiment to explore how plants absorb water. The experiment involves using celery stalks, water, and food coloring to visually observe water movement through plant xylem. Laura explains the science behind water absorption, photosynthesis, and transpiration in plants. The experiment's results show how colored water travels up the celery, illustrating the process. The video concludes with suggestions for further exploration using white flowers.

What is the main purpose of the celery and food coloring experiment?

• To see how food coloring changes the taste of celery

• To observe the effect of sunlight on celery

• To learn about how plants absorb water

• To understand the growth rate of celery

Which of the following is NOT a supply needed for the experiment?

• Scissors

• Soil

• Food coloring

• Celery

What is the first step in setting up the experiment?

• Placing celery in the jars

• Cutting the celery

• Adding food coloring to water

• Stirring the water

Why do we cut the bottoms off the celery stalks before placing them in the jars?

• To help them absorb water better

• To change their color

• To remove any dirt

• To make them fit in the jars

What is the role of xylem in plants?

• To protect the plant from pests

• To store nutrients

• To produce food for the plant

• To transport water from roots to leaves

What process in leaves uses water to make energy?

• Evaporation

• Respiration

• Photosynthesis

• Transpiration

What is the process called when water exits through tiny pores in leaves?

• Diffusion

• Transpiration

• Photosynthesis

• Osmosis

What did the experiment demonstrate about the movement of water in celery?

• Water stays at the base of the celery

• Water moves from the leaves to the roots

• Water evaporates quickly from the celery

• Water moves from the roots to the leaves

What was observed in the celery after it was left in colored water?

• The celery grew taller

• The celery absorbed the color, showing it in the leaves

• The celery dried out

• The celery became softer

What is suggested as a further experiment after the celery experiment?

• Trying the experiment with white flowers

• Using different vegetables

• Using colored paper

• Adding sugar to the water
