Plant Growth and Vascular System

The video tutorial explains how plants absorb nutrients from the soil through their root systems, using processes like diffusion and active transport. It compares the plant's vascular system to the human circulatory system, highlighting the roles of xylem and phloem. A seed germination experiment is demonstrated, showing the development of roots and cotyledons. The video also covers the importance of nutrients like nitrogen, phosphorus, and potassium for plant growth and explains how xylem and phloem function in nutrient and water transport.

What process do plants use to absorb some nutrients from the soil without energy?

• Osmosis

• Diffusion

• Photosynthesis

• Active transport

Which part of the plant's vascular system is responsible for transporting water?

• Root hairs

• Xylem

• Phloem

• Cambium

What is the primary function of the phloem in plants?

• Absorbing sunlight

• Transporting food

• Providing structural support

• Transporting water

In the seed germination experiment, what is the role of root hairs?

• Protecting the seed

• Absorbing nutrients and water

• Providing structural support

• Transporting food

What are the first leaves that emerge from a germinated seed called?

• Seed coat

• Cotyledons

• Radical

• True leaves

Why is perlite added to potting soil mixes?

• To increase weight

• To improve drainage

• To provide nutrients

• To retain moisture

Which three macronutrients are essential for plant growth?

• Nitrogen, Phosphorus, Potassium

• Calcium, Magnesium, Sulfur

• Iron, Zinc, Copper

• Carbon, Hydrogen, Oxygen

What is the cambium in a plant stem responsible for?

• Transporting food

• Transporting water

• Growth and nutrient transport

• Photosynthesis

What do the growth rings in a tree trunk indicate?

• The tree's height

• The tree's age

• The tree's health

• The tree's nutrient levels

What happens if the cambium layer of a tree is damaged?

• The tree will produce more leaves

• The tree will stop photosynthesis

• The tree will grow faster

• The tree will die
