Where do you think the tiny remains of plants and animals in the stream come from?
Tiny remains of animals and plants in streams come from the mountains. When it rains, these remains are washed down the mountains toward the streams.
Why is water evaporation so important to leaves?
Water evaporation from leaves, known as transpiration, is important as it helps plants regulate their internal temperature, transport nutrients and minerals from the soil to other parts of the plant, and maintain cell turgidity. It also creates a suction force that pulls water up from the roots to the leaves through the xylem vessels, a process known as the transpiration stream.

What is the transperation stream?
In plants, the transpiration stream is the uninterrupted stream of water, and other, which is taken up by the roots and, via the xylem vessels, transported to the leaves where it will eventually evaporate into the air/applets-interface of the substomatal cavity. It is driven in by capillary action and in some plants root pressure. The main driving factor is the difference in water potential between the soil and the substomatal cavity caused by transpiration.
What role do plants play in the water cycle?
unlike evaporation which is part of the water cycle; plants draw water from below the evaporation zone; water that is tightly held by clay particles is drawn up by the plants in the transpiration stream and diffused into the atmosphere.
If beavers built a dam on a stream the kinds of plants and animals that lived around the stream would not be affected true or false if answered how?
true
Why is transpiration stream important?
The transpiration stream is important because it helps to transport water and nutrients from the roots to the leaves of a plant. This process is essential for maintaining turgor pressure in plant cells, which in turn supports plant structure and growth. Additionally, the movement of water through the plant helps to cool the leaves and assists in the uptake of minerals and other essential nutrients from the soil.
What process is not involved in moving water from roots to leaves in a plant?
Photosynthesis. The process of moving water from roots to leaves is called transpiration through a process known as the transpiration stream. Photosynthesis is the process where plants convert light energy into chemical energy to produce glucose.
What happens in transpiration stream?
The transpiration stream refers to the movement of water from the roots of a plant, through the stem, and ultimately to the leaves, where it evaporates into the atmosphere. This process begins when water absorbed by the roots is transported upward through xylem vessels, driven by capillary action and the negative pressure created by water evaporating from the stomata in the leaves. Transpiration not only helps to cool the plant but also facilitates the uptake of essential nutrients and minerals dissolved in the water. Overall, the transpiration stream is crucial for maintaining plant health and hydration.
How do you think windy conditions will affect the flow of the transpiration stream?
Windy conditions can increase the rate of transpiration by promoting more evaporation from the leaf surface. This can create a steeper concentration gradient, leading to faster movement of water through the plant. However, excessive wind can also cause plants to close their stomata to prevent water loss, potentially reducing the transpiration rate.

Why does the water move from the soil into plant root?
because transpiration stream is created after every water is lost
