Tree Anatomy and Functions: Exploring Parts and Their Roles

The video explains the three main parts of a tree: the crown, trunk, and roots. It details the different types of crowns and their functions, such as supporting leaves and fruits and facilitating photosynthesis. The trunk's structure is explored, highlighting its layers like hardwood, sapwood, cambium, phloem, and bark, each with specific roles in support and nutrient transport. The roots are divided into root collar, stability roots, and feeder roots, each contributing to the tree's stability and nutrient absorption. The video concludes with a call to action for further learning.

What are the three main parts of a tree?

• Branches, trunk, and roots

• Leaves, trunk, and roots

• Crown, trunk, and roots

• Crown, trunk, and branches

Which type of crown is characterized by thin branches that droop downwards?

• Columnar crown

• Weeping crown

• Pyramidal crown

• Full crown

What is the primary function of chloroplasts in leaves?

• Conduct photosynthesis

• Store water

• Transport nutrients

• Provide structural support

Which crown type is ideal for providing shade due to its width?

• Weeping crown

• Columnar crown

• Full crown

• Spreading crown

Which layer of the trunk is responsible for transporting water and nutrients?

• Hardwood

• Sapwood

• Phloem

• Cambium

What is the role of the cambium layer in a tree trunk?

• Stores excess food

• Distributes organic nutrients

• Protects the inner layers

• Acts as a secondary growing layer

What is the function of the outer bark of a tree?

• Stores water

• Supports the crown

• Conducts photosynthesis

• Protects inner layers

What is the main role of the phloem layer in a tree trunk?

• Distributes organic nutrients

• Stores water

• Provides structural support

• Protects the inner layers

Which part of the roots is primarily responsible for absorbing water and nutrients?

• Root collar

• Outer bark

• Stability roots

• Feeder roots

What happens when stability roots become rotten or underdeveloped?

• The tree produces more leaves

• The tree tips over

• The tree absorbs more nutrients

• The tree grows faster
