Plant Transport

3. A substance called __________ is present in the walls of tubes transporting water, so as to provide mechanical strength to prevent collapse of the tubes.
5. This sugar is being transported in the phloem in the stems of plants.
6. The process by which water enters the root hair cells of a plant is known as ____________.
8. The effect of water moving up very narrow tubes due to interactions between water molecules and the surface of the tubes is known as ____________ action.
9. The process where by water vapour is lost mainly from the stomata of a plant is known as ____________.
11. The phloem consists mainly of _______ tubes and companion cells.
13. The _________ on the surface of the leaf prevents water loss from the leaf by evaporation.
14. This component of the vascular bundle is closer to the interior of the stem.

1. Many _______________ are present in the companion cells to provide energy needed to load sugars into the sieve tubes.
2. The process of transporting manufactured food substances such as sugars and amino acids in plants is known as ______________.
4. Wilting can be disadvantageous as the closed stomata reduce the amount of carbon dioxide from entering the plant, limiting the process of _____________.
7. The phloem in the vascular bundle of a leaf is closer to the _________ epidermis of the leaf.
10. Wilting can be advantageous to the plant as it causes the leaf to fold up to ________ the surface area exposed to sunlight.
12. Holes in sieve _______ allow rapid flow of sugars manufactured in the leaves through the sieve tubes.
