Which lobe of the cerebrum is responsible for planning and initiating voluntary motor movement?

The frontal lobe of the cerebrum is responsible for planning and initiating voluntary motor movement. The name frontal comes from the position of this lobe- it is located just beneath the frontal bone. The frontal lobe is also responsible for other cognitive functioning (i.e. perception, learning, remembering, judging & problem solving).

- Rate of respiration is relatively constant throughout the day. It can be concluded that plants do not rely on sunlight to respire.

- Rate of photosynthesis varies at different times of the day and it occurs at its greatest at noon. It can be concluded that plants rely heavily on sunlight to photosynthesise.

Hope this helps:)
