Transport System In Plant Cells

Has a waxy layer to Prevent water loss

Allows light to pass through the plant and prevents water loss.

Main site of photosynthesis.

Photosynthetic cells arranged in a way to allow air spaces and gas exchange.

Pairs of cells that control the opening and closing of stomata at night.

Air spaces that allows oxygen and water to leave and carbon dioxide to enter the leaf.

Water and minerals flow in an up direction from the roots to all other parts of the plant. Sugars flow from the green leaves to all over the plant, including down to the roots

Xylem is a tissue consisting of dead, hollowed-out cells that form a system of pipes They are lignified (strengthened) with rings of lignin to be able to withstand the pressure changes as water moves through the plant

Sugar is transported in phloem cells. Other companion cells provide the energy for sieve cells. The walls of the sieve cells have pores through which sugar is transported from cell to cell
