Plant Structure and Function Concepts

This video tutorial by Mr. Anderson covers plant nutrition and transport. It explains the essential elements plants need, such as carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur. The tutorial delves into the structure and function of roots, stems, and leaves, highlighting the differences between monocots and dicots. It also discusses the processes of photosynthesis and cellular respiration, emphasizing the roles of xylem and phloem in water and nutrient transport. The video concludes with an explanation of how plants transport and store sugars, using the source-to-sink model.

Which of the following elements is NOT essential for plant nutrition?

• Sulfur

• Helium

• Hydrogen

• Carbon

How do plants primarily obtain carbon?

• By consuming other organisms

• From carbon dioxide in the air

• By absorbing sunlight

• Through their roots

In what way do plants differ from animals in obtaining nutrients?

• Plants breathe oxygen

• Plants have a circulatory system

• Plants eat other organisms

• Plants absorb nutrients through roots

What is the primary function of root hairs?

• To increase surface area for absorption

• To perform photosynthesis

• To anchor the plant

• To store nutrients

What role do symbiotic fungi play in plant roots?

• They protect the plant from pests

• They produce food for the plant

• They help absorb more nutrients

• They provide structural support

Which characteristic is typical of dicot leaves?

• Parallel veins

• Net-like venation

• Single vein

• No veins

What is the function of the stomata in leaves?

• To absorb sunlight

• To take in carbon dioxide and release water

• To store nutrients

• To protect the leaf

What is the primary function of xylem in plants?

• Performing photosynthesis

• Storing nutrients

• Transporting water

• Transporting sugars

How does water move up through a plant?

• Through active transport

• By being absorbed by the leaves

• Through a pulling process aided by the sun

• By being pushed from the roots

What is the role of phloem in plants?

• Absorbing nutrients

• Providing structural support

• Transporting sugars

• Transporting water
