Hormones Target Specific Cells And Tissues

Question 1

Where do cells produce hormones in plants?

Answer 1

Roots, stem tip, buds.

Question 2

Explain: plants don’t send electrical impulses to stimulate their cells to move?

Answer 2

Bcs plants form electrochemical gradients in the form of a difference in the concentration of some ions, these gradients move through a number of membranes.

Question 3

What are the factors affected the plant responses?

Answer 3

•hormone’s location
•hormone’s concentration
•hormone interaction with other hormone

Question 4

What do we call the area affected by hormones?

Answer 4

Hormone target cells.

Question 5

Mention the condition that allow the target cells to respond to a hormone?

Answer 5

For target cells to respond to a hormone, they must be detected by a receptor. If a receptor is not detected or if the receptor is blocked, there is no responses by the plant.

Question 6

Explain: only target cells are influenced by hormones not any other cells?

Answer 6

Because of the presence of hormones receptors on the surface of the plasma membrane of the cell.

Question 7

Define synergist hormone.

Answer 7

Two hormones interact andprompt a greater response than they would alone.

Question 8

Define antagonist hormones.

Answer 8

Two hormones with opposite effects interact to balance each other and the net effect determines a response.
