Text SolutionText solutionverified iconVerified

The main function of the leaves is to carry out the process of photosynthesis. However, in a few plants, leaves are modified to perform different functions.
(a) Tendrils: The leaves of a pea plant are modified into tendrils that help the plant in climbing.
(b) Spines: The leaves in cactus are modified into sharp spines that act as an organ of defence.
(c) Phyllode: The leaves of some Australian acacia are short-lived and soon replaced by flattened, green structures called as phyllodes that arise from the petiole of the leaves. The petioles in these plants synthesize food.
(d) Pitcher: The leaves of the pitcher plant are modified into pitcher-like structures, which contain digestive juices and help in trapping and digesting insects.

QUESTION 10 Procedure: Ask the subject to stand with their feet together and back close to the whiteboard, but not touching the board. Using a marker, mark the board on both sides of the subject's body (marking the board as close to the subject's body as feasible). Have the subject stand in this position staring straight ahead without moving for 3 minutes. Does the subject sway? Use a different color marker to indicate on the board the range that the subject sways. Repeat the process again, but this time have the subject close his or her eyes. Use a different color marker to indicate on the board the range that the subject sways with his or her eyes closed. Have the person turn so one side is facing the board. Repeat the above process with eyes open and then closed. If the subject is steady with eyes open, but demonstrates significant sway with eyes closed, they have a positive Romberg Test (This test has been used by law enforcement in the field using a 30-second variation as a sort of sobriety test. Asking the subject to estimate 30 seconds may also provide hints if the subject is on stimulant or depressant drugs). a. Which pathway carries proprioceptive information? b. If a person has a NEGATIVE Romberg test but still demonstrates an ataxia, what other brain area may be implicated? a. vestibulospinal; b. spinocerebellar a. dorsal columns; b. cerebellum a. dorsal columns; b. optic a. spinothalamic; b. cerebellum
