Summary Introduction
To write:
The explanation for several structural features that help vascular plants to maintain stable internal water content.
Introduction:
Homeostasis is the ability of living organisms to maintain a stable internal state that persists without being affected by the outer environment. In vascular plants, several structural features help them to maintain their internal water content stable such as stomatal movement, short and spiny leaves in xerophytic plants, etc.

A principle of biology is that living organisms maintainhomeostasis. Explain how several structural features helpvascular plants maintain stable internal water content.
Describe the pathway water would take up the stem to the leaf of a plant. Describe the water's movement through any cells, tissues, and/or systems of the plant body.

- Sudents are asked to pair a plant structure to its physiological function and give evidence for why that structure is important for the process they describe Anne: The root hairs are used to pull in sugars available in the soil that give the plant energy for growth and reproduction. Jamil: The phloem is needed for cellular respiration as it transports the carbon dioxide to the leaves in order to perform cellular respiration. Shantal: The cambium is important for phossynthesis because it allows water into the plant which is needed as a reactant for photosynthesis. Enrique The guard cells are needed during transpiration because they open and close to regulate the gases that enter and leave the plant. Which student correctly described a plant structure and its physiological function? O Anne Jamil O Shantal O Enriquearrow_forwardChoose the statements that apply to transpiration in the cohesion-tension theory. (Check all that apply) Check All That Apply The H-bonds in water allow for cohesion. Water pressure builds in roots to drive water up the plant. Exposed water in leaves evaporates into drier air. Water forms a continuous stream from leaf into the root. In addition to water, heat is lost cooling the plant during transpiration.arrow_forwardDescribe the pathway of water movement in plants.arrow_forward
- From environmental pressures to obtain and retain water, many plants developed to transport nutrients and water.

- In plants, water is transported through vessels called xylern. The cohesiveness of water molecules allows them to travel up the walls of the vessel. However, for most plants this is not enough to move the water all the way to the top of the plant. How do plants overcome the force of gravity and move water to their upper tissues ? Root hairs push water through the roots and up into the xylem. Plants absorb water through transpiration to supply their upper tissues with water . С The guard cells surrounding the stomata expand and contract, pushing water through the xylem. Water escapes from the leaves through transpiration, creating a vacuum which pulls water up the xylem.arrow_forwardDiscuss the types of meristems based on their position in the plant bodyarrow_forwardAll plants possess three basic types of tissues.

How do animals benefit from using fat? How do plants benefit from using starch? Name two plants that storeenergy for many years. How long is long-term storage for these species? What two plant parts often use fats and why? Storage tissue in enlarged roots is vascularized. How is that important to the plant?arrow_forward
