Final answer:
Tree growth doesn't need to be measured annually to be accurate; this statement is false.
The most common plants in the taiga biome are coniferous trees, not deciduous trees. Therefore, the correct option is C.
Step-by-step explanation:
The student's question regarding the dominant plant types in the taiga biome reflects a concept in biology focusing on different biomes and their characteristic vegetation. The statement that growth in trees must be measured every year to be accurate is false; tree growth can be measured at different intervals and still provide accurate data. However, the most common types of plants in the taiga biome are coniferous trees.
As for the options provided in the question, among the statements, letter c, stating that boreal forests are dominated by deciduous trees, is false. Boreal forests, also known as the taiga, are primarily composed of cold-tolerant cone-bearing plants, such as evergreen coniferous trees like pines, spruce, and fir. These trees are adapted to the long and cold winters characteristic of this biome.
