Secoyas gigantes

The video explains the impressive height of giant redwoods, their need for sunlight and water, and how they absorb water through roots and transport it via xylem cells. It covers photosynthesis, where leaves use water and carbon dioxide to produce food, and the role of the trunk in circulating nutrients and supporting growth.

What is one advantage of the giant redwoods' height?

• They are less likely to be cut down.

• Their leaves have better access to sunlight.

• They can absorb more water.

• They can grow in any climate.

How do redwoods absorb water?

• Through their bark

• Through their leaves

• Through their roots

• Through their branches

What are the pipe-like cells in the trunk that carry water called?

• Phloem

• Chlorophyll

• Xylem

• Stomata

What two elements do leaves use during photosynthesis?

• Water and oxygen

• Oxygen and nitrogen

• Water and carbon dioxide

• Carbon dioxide and nitrogen

What is the role of phloem cells in redwoods?

• To support the tree structure

• To carry food from leaves to roots

• To transport water

• To absorb sunlight
