Which structure is responsible for primary and secondary growth in plants

xylem

mesophyll

meristem

petiole

Meristem

Explanation:

Primary growth refers to the increase in the length of the root and the shoot as a result of division of cells in the apical meristem in the shoot.Secondary growth on the other hand is the increase in the girth or thickness of the plant as a result of cell division in the lateral meristem.Meristem is therefore the structure of plant responsible for primary and secondary growth.Meristem may be classified into two namely; the apical meristem and the lateral meristem. The apical meristem is responsible for primary growth whereas the lateral meristem is responsible for secondary growth.

If these are the missing choices: a. to determine skin temperature, place the back of your hand against the patient's skin.b. determine body temperature by touching the patient's hands and feet.c. skin temperature will tell you very little about this patient's condition or well-being.d. the patient's skin temperature and color will likely be warm and red.my answer is: a. to determine skin temperature, place the back of your hand against the patient's skin. using the back of the hand to check for temperature rather than the palm is more effective because the back of the hand has more nerves that can feel and transmit the temperature than the palm.
