    Where and how does carbon dioxide enter a plant? - ProProfs

    Where and how does carbon dioxide enter a plant?

    • A

    • B

    • C

    • D

    Correct Answer
    A. D
    Explanation
    Carbon dioxide enters the leaves through stomata by a diffusion process. The gas diffuses into the intercellular air spaces and then dissolves in the water layer outside the mesophyll cells.

          The diagram shows a transverse section from the middle of a root of a dicotyledonous plant. In which tissue are sugars and amino acids transported?

    • A

    • B

    • C

    • D

    Correct Answer
    A. B
    Explanation
    Xylem is found in the centre of the root forming a star shape. The large cells thickened with lignin are the xylem cells which transport water and mineral ions from roots to stems to leaves. Phloem are much smaller found mostly at B. A - xylem, C and D - root cortical cells

    The graph shows how the rate of photosynthesis in a plant varies with light intensity at two different carbon dioxide concentrations. The temperature is kept constant at 20 °C. Which factor is limiting the rate of photosynthesis at point X?   - ProProfs

    The graph shows how the rate of photosynthesis in a plant varies with light intensity at two different carbon dioxide concentrations. The temperature is kept constant at 20 °C. Which factor is limiting the rate of photosynthesis at point X?  

    • Oxygen concentration

    • Chlorophyll availability

    • Light intensity and carbon dioxide concentration

    • Water availability

    Correct Answer
    A. Light intensity and carbon dioxide concentration
    Explanation
    Limiting factor - factor required in minimum amount. As light intensity increases, the rate of photosynthesis does not continue to increase. Other factors will help to increase the rate of photosynthesis

    Which graph shows the effect of temperature on the rate of photosynthesis?

    • A

    • B

    • C

    • D

    Correct Answer
    A. D
    Explanation
    Photosynthesis is controlled by enzymes. High temperature will denature the enzymes. So the graph is the same as that of the enzyme.

    Four regions of a green leaf are listed. 1. air space 2. spongy mesophyll cell 3. stoma 4. xylem vessel In which order does a molecule of water, transported from the stem, pass through these regions into the air surrounding the leaf? - ProProfs

    Four regions of a green leaf are listed. 1. air space 2. spongy mesophyll cell 3. stoma 4. xylem vessel In which order does a molecule of water, transported from the stem, pass through these regions into the air surrounding the leaf?

    • A

    • B

    • C

    • D

    Correct Answer
    A. C
    Explanation
    Water is transported by xylem vessels to the leaf xylem. Water enters the spongy mesophyll cells by osmosis. Water forms a layer outside the walls of mesophyll cells. Water evaporates into water vapour into the intercellular air spaces. Water vapour diffuses out of the stomata by transpiration.

    • Palisade cells in the leaves

    • Phloem cells in the stem

    • Xylem vessels in the stem

    Correct Answer
    A. Xylem vessels in the stem

    Four tubes, A, B, C and D are left in sunlight for one hour. The bicarbonate indicator solution in each tube is red at the start of the experiment. Bicarbonate indicator solution stays red if there is no change in carbon dioxide concentration. The indicator goes yellow if carbon dioxide concentration increases and purple if the carbon dioxide concentration decreases. In which tube does the colour change to purple? - ProProfs

    Four tubes, A, B, C and D are left in sunlight for one hour. The bicarbonate indicator solution in each tube is red at the start of the experiment. Bicarbonate indicator solution stays red if there is no change in carbon dioxide concentration. The indicator goes yellow if carbon dioxide concentration increases and purple if the carbon dioxide concentration decreases. In which tube does the colour change to purple?

    • A

    • B

    • C

    • D

    Correct Answer
    A. B
    Explanation
    Bicarbonate indicator solution will change to yellow when it is acidic - presence of CO2.
    If less CO2 and more O2 due to photosynthesis, the indicator changes to purple - less CO2.
    B - photosynthesis takes place, so more O2 than CO2, purple.
    Respiration - breaks down glucose to release energy and CO2, the indicator turns yellow.

    • Mineral salts to the leaves.

    • Nutrients to the roots.

    • Oxygen to the roots

    • Water to the leaves.

    Correct Answer
    A. Nutrients to the roots.
    Explanation
    Bark - phloem tissues, no sucrose and amino acids transported by phloem from leaves to roots.

          A young plant may wilt when dug up and re-planted in another place. What causes this?

    • The leaves lose less water.

    • The roots cannot take up mineral salts.

    • The stem cannot transport water.

    • The surface area of the root is reduced.

    Correct Answer
    A. The surface area of the root is reduced.
    Explanation
    When the plant is dug up, some of the roots are damaged or torn away. Hence, less roots results in less surface area for water uptake by osmosis

    The cell wall of xylem vessels is made of ___________ to provide support to the plant. It also helps to prevent bending of stem caused by wind.

    Correct Answer
    lignin
    support
    bending
    Explanation
    The cell wall of xylem vessels is made of lignin, which provides support to the plant. Lignin is a complex polymer that gives rigidity and strength to the cell walls, allowing them to withstand the pressure exerted by water and provide structural support to the plant. Additionally, lignin helps to prevent the bending of the stem caused by wind, as it adds stiffness and resistance to deformation.
