EXPERIMENT LAB PLANT
WATER UPTAKE AND TRANSPORT
, INTRODUCTION
Objectives
1. To demonstrate how the solution moves through the stalk.
2. To prepare and identify the tissues in a stained cross-section of the plant's stem.
3. To discuss the water transport in the stem of a plant.
To survive, plants need water and nutrients. As Ursache. R (2015) stated that water,
nutrients, and other molecules must be transported throughout the plant's body for proper
development and growth. The majority of plants can be found growing in soil to support the
growth of the plants. The soil provides nutrients, water and moisture. There is no blood
circulation in plants, but they have a network of tiny tubes known as xylem that transport water
throughout the plant body. Xylem is the result of extensive cell overlap.
Xylem tissue comprises four types of cells: tracheids, vessels, xylem parenchyma, and xylem
fibres. The extinction of these cells results in the formation of a long tube made up of hollow
cavities. The xylem vessels of plants are like a series of drinking straws, stretching from the roots
to the tips of the leaves. Aside from the water, other chemicals and nutrients can combine with
water and travel up the stem. After photosynthesis, the sap is transported to other parts of the
plant via phloem vessels.
