AGRICULTURE - Movement of substances

Which of the following is the function for xylem?

• Transport dissolved photosynthesis products from the leaves to all parts of the plants

• Transport water and mineral salts from the root, to the stem and to the leaves

Which of the following process is use SPECIFICALLY to transport water from the soil to the root hair cell?

• osmosis

• diffusion

• active transport

Which of the following describe the movement of mineral salts from the soil to the root hair cell?

• The movement of mineral salt from lower concentration area to a higher concentration area across partially permeable membrane, using energy. The process involved is called active transport.

• The movement of mineral salt from a higher water concentration area to a lower water concentration area, across partially permeable membrane, without using energy. The process involved is called osmosis

• The movement of mineral salt from lower concentration area to a higher concentration area across partially permeable membrane, without using energy. The process involved is called diffusion.

What is photosynthesis?

• It is a process where sucrose is transported from the leaves to all parts of the plants

• It is a process where green leaves are producing carbon dioxide during the day

• It is a process where green leaves absorb carbon dioxide and uses water to make glucose and oxygen, in the presence of chlorophyll and sunlight

• It is a process where green leaves absorb oxygen and uses glucose to make water and carbon dioxide, in the presence of chlorophyll and sunlight

Which statements best describe translocation?

• It is a process where water travels through the roots and to the leaves through xylem vessels

• It is a process where the sugars made from the leaves are transported all over the plant

• It is a process where the sugar is broken down in the presence of oxygen, to release energy

• It is a process where the water vapour diffuse out of the leaves through the stomata

Which statement best describes transpiration

• It is a process where water travels through the roots and to the leaves through xylem vessels

• It is a process where the sugars made from the leaves are transported all over the plant

• It is a process where the sugar is broken down in the presence of oxygen, to release energy

• It is a process where the water vapour diffuse out of the leaves through the stomata

Which statement best describes transpiration pull or transpiration stream

• It is a process where the water vapour diffuse out of the leaves through the stomata

• It is a process where the sugar is broken down in the presence of oxygen, to release energy

• It is a process where the sugars made from the leaves are transported all over the plant

• It is a process where water travels through the roots and to the leaves through xylem vessels

Which of the statement best describe respiration

• It is a process where the sugars made from the leaves are transported all over the plant

• It is a process where water travels through the roots and to the leaves through xylem vessels

• It is a process where the water vapour diffuse out of the leaves through the stomata

• It is a process where the sugar is broken down in the presence of oxygen, to release energy

Which of the following statements best describe wilting

• Wilting occurs when plant lose water by transpiration slower than they are able to absorbed through the roots

• Wilting occurs when plant lose water by transpiration more than they are able to absorbed through the roots

Which of the following will decrease the rate of transpiration?

• Windy day

• High humidity surrounding the leaves (more water vapour outside of the leaves)

• Hot day

• high light intensity
