Explanation:ask small question
1.It is constituted of xylem, specialized for transport of water, and phloem, that transports photosynthates. These two differentiated tissues are specified early in development and arise from divisions in the procambium, which is the vascular meristem during primary growth.
2.he different components of the xylem include tracheids, vessels, xylem parenchyma and xylem fibers.
Tracheids form the main conductive cells of some non-flowering plants. ...
Vessels are advanced water conductive elements mostly seen in flowering plants. ...
Xylem parenchyma are the living cells of the xylem.
3.he xylem vessels in turn draw water from the xylem of the main stem. This creates a pull which is known as transpiration pull. The lumen of tracheids and vessels of a xylem link to form a narrow tube and water rises in the narrow tube due to the force of surface tension. This phenomenon is known as capillarity.
5.The two main functions of stomata are to allow for the uptake of carbon dioxide and to limit the loss of water due to evaporation. In many plants, stomata remain open during the day and closed at night. Stomata are open during the day because this is when photosynthesis typically occurs
