Which scenario could be used to test phototropism?Two sets of plants could be placed in a dark room and the growth monitored.Two sets of plants could be placed in a lighted room and the growth monitored.One set of plants could be placed in a room with a light on the right side and one set in a room with a light on the left side; plant growth is monitoredOne set of plants could be placed in a lighted room and one set in a dark room; plant growth is monitored.30s6.L.2.2
- Q9A large tree in the forest blocks the sunlight for a smaller plant. How could this affect the smaller plant?It could force the smaller plant to retrieve food molecules from the soil.It could decrease the amount of food produced by the smaller plant.It could force the smaller plant to rely on water for nutrition until conditions improve.It could increase the amount of oxygen released by the smaller plant.30s6.L.2.3
