Leaf tissues

Dermal tissue

Consists of upper and lower epidermis

What is the role of dermal tissue

Protection from water loss as covered with waterproof cuticle

Ground tissue

Consists of mesophyll cells

What is the role of ground tissue

The photosynthetic tissue of the leaf with chloroplasts in the cells

Vascular tissue

Consists of xylem and phloem which are transport tissues in plants

The role of the xylem

Transports water up the stem as a reactant of photosynthesis

What is the role of the phloem

Transports sugar produced as sucrose to other parts of the plant

Where would phloem transport sucrose to?

Meristems of the root

What is a characteristic of the cuticle?

It is waterproof

Where in the leaf does photosynthesis occur the most

Palisade mesophyll layer

Why does photosynthesis occur most in the palisade mesophyll layer

More chloroplasts per cell

What ways if the leaf adapted for photosynthesis

Large surface area, large number of chloroplasts, air spaces, vascular system, thin

What substances are involved in leaf metabolism and which pass through the stomata

Carbon dioxide, oxygen, water vapour

The concentration of which gas influences the diameter of the stomata

Carbon dioxide
