Leaf structure and Photosynthesis

What is the function of xylem and phloe?

• Xylem transport water/glucose

• Xylem transport food

• Phloe transport water/glucose

• Phloe transport food

Which layer transporting vessels to carry glucose and water?

• Waxy Cuticle

• Palisade Mesophyll

• Vascular Bundle

• Spongy Mesophyll

Choose function of waxy cuticle

• Allow the interchange of gases

• To protect itself

• Prevent lost of water

• To maximize the absorption of sunlight

What’s the name of 5 & 7

• Stomata

• Lower epidermis

• Guard cells

• Palisade Mesophyll

Which adaption absorb sunlight and transfer energy into chemical

• Thin

• Chlorophyll

• Stomata

• Veins

Choose purposes of spongy mesophyll layer

• To diffuse into the leaf easily

• To increase light absorption

• To protect the leaf

• To absorb all available light

Most of the chloroplasts are located in the

• Upper epidermis

• Pallisade mesophyll layer

• Lower epidermis

• Spongy mesophyll layer

The movement of gases, co2 in and o2 out, occurs through the

• Phloem cells

• Xylem cells

• Stomates

• Root hair cells

Water & soluble nutrients are transported throughout the plant by the

• Phloem

• Xylem

• Upper epidermis

• Lower epidermis

Sugar (glucose) made by the plant as a product of photosynthesis is transported to all the cells of the plant by the

• Phloem

• Xylem

• Spongy mesophyll

• Cuticle layer
