6 Questions
What are the limiting factors of photosynthesis?
Carbon dioxide concentration, light intensity, and temperature
Explain why the structure of a leaf has a waxy cuticle.
To protect against water loss without blocking sunlight.
Where are the chloroplasts located in a leaf and what is their function?
Chloroplasts are located in the palisade mesophyll cells and contain chlorophyll that absorbs light energy for photosynthesis.
Why do leaves have a large surface area?
To allow more diffusion of carbon dioxide and more absorption of light during photosynthesis.
What is the purpose of spongy mesophyll cells in a leaf?
Spongy mesophyll cells with air spaces allow for easy diffusion of carbon dioxide through the leaf.
Describe the role of the upper epidermis in a leaf.
The upper epidermis is thin and transparent, allowing more light to reach the palisade mesophyll cells.
