True or false? in the Xylem vessel water and mineral salts only move in one direction (upwards)

True
False

Correct Answer

A. True

Explanation

In the xylem vessel, water and mineral salts move in one direction, which is upwards. This is because the xylem vessels are specialized structures that transport water and nutrients from the roots to the rest of the plant. The movement is facilitated by a combination of factors including transpiration, cohesion, and adhesion. Transpiration, which is the loss of water through the leaves, creates a negative pressure that pulls water up the xylem vessels. Cohesion and adhesion between water molecules and the xylem walls also contribute to the upward movement. Therefore, the statement "True" accurately describes the movement of water and mineral salts in the xylem vessel.

True or false? the Phloem vessel is made from living cell in the plant

True
False

Correct Answer

A. True

Explanation

The phloem vessel is made from living cells in the plant. This is because the phloem is responsible for transporting sugars, nutrients, and other organic compounds from the leaves to other parts of the plant. This requires an active and living system, which is why the phloem vessels are composed of living cells. These cells are specialized to form tubes that allow for the movement of substances throughout the plant.

True or false? in the Phloem sugar and amino acid moves in both directions (upwards and downwards)

True
False

Correct Answer

A. True

Explanation

In the phloem, sugar and amino acids move in both directions, upwards and downwards. This is because the phloem is responsible for the transportation of nutrients, including sugars produced during photosynthesis, from the leaves to other parts of the plant, as well as the movement of amino acids from the roots to the rest of the plant. This bidirectional movement allows for the distribution of essential nutrients throughout the plant, ensuring its growth and development.

Water that is lost from the leaves occurs by the process called:

Transpiration
Translocation
Osmosis
Diffusion

Correct Answer

A. Transpiration

Explanation

Transpiration is the process by which water is lost from the leaves of a plant. It involves the movement of water vapor from the plant's stomata, which are small openings on the surface of the leaves. This water vapor escapes into the surrounding atmosphere, resulting in the loss of water from the plant. Transpiration helps in the transportation of water and nutrients from the roots to the rest of the plant, and also aids in cooling the plant. Therefore, transpiration is the correct answer for the process through which water is lost from the leaves.

Plants transport water and mineral salt through the:

Phloem vessel
Xylem vessel
Vein vessel
Root vessel

Correct Answer

A. Xylem vessel

Explanation

The correct answer is xylem vessel. Xylem vessels are responsible for transporting water and mineral salts from the roots to the rest of the plant. These vessels are composed of specialized cells that form a continuous network throughout the plant, allowing for the upward movement of water through capillary action and transpiration pull. Phloem vessels, on the other hand, are responsible for transporting sugars and other organic compounds from the leaves to other parts of the plant. Vein vessels and root vessels are not anatomical terms commonly used to describe plant transport systems.

The food made in the leaves of plants are transported by a process called:

Diffusion
Osmosis
Translocation
None of these

Correct Answer

A. Translocation

Explanation

Translocation is the process by which food made in the leaves of plants is transported to other parts of the plant, such as the stems, roots, and fruits. This process involves the movement of sugars and other organic molecules through the phloem tissue. Diffusion and osmosis are not the correct answers because they do not specifically refer to the transportation of food in plants.

True or false? Xylem vessel is made from living cell in the plant

True
False

Correct Answer

A. False

Explanation

The xylem vessel is not made from living cells in the plant. Xylem vessels are actually composed of dead cells that have thickened cell walls and no cell contents. These cells, known as tracheids and vessel elements, are responsible for transporting water and minerals from the roots to the rest of the plant. Their dead state allows for efficient water movement due to the absence of cell membranes and cytoplasmic contents.

Plants lose more water from their leaves by transpiration on a day that is:

Very cold and windy
Hot and windy
Wet and windy
Hot and no wind blowing

Correct Answer

A. Hot and windy

Explanation

Plants lose more water from their leaves by transpiration on a hot and windy day because the combination of high temperature and wind increases the rate of evaporation. The hot temperature causes the water in the leaves to evaporate more quickly, while the wind blows away the water vapor, creating a drier environment around the plant. This leads to a higher rate of transpiration as the plant tries to replace the lost water, resulting in more water loss from the leaves.

In the diagram of the stem, the xylem is on the _ and the phloem on the ______

Outside and inside
Inside and outside
Outside and outside
Inside and inside

Correct Answer

A. Inside and outside

Explanation

In the diagram of the stem, the xylem is located on the inside and the phloem is located on the outside. This is because xylem is responsible for transporting water and minerals from the roots to the rest of the plant, and it is located in the center of the stem. On the other hand, phloem is responsible for transporting sugars and other organic molecules from the leaves to the rest of the plant, and it is located on the outer side of the stem.
