Summary Introduction
Introduction: Arabidopsis belongs to the family Brassicaceae. Arabidopsis thaliana is otherwise called thale cress or mouse-ear cress. It is a small flowering plant related to mustard and cabbage. Arabidopsis is used as the model organism for studying plant biology. The whole genome is sequenced first in this plant.

experiment. Based on your understanding of phototropism, provide
predictions about the direction of plant growth for the following two
scenarios, and explain your reasoning.

to the dark side of the stem.
2. The tip of the coleoptile is removed and lanolin with auxin is applied
to the light side of the stem.

- An angiosperm called “ghost plant” does not produce chlorophyll orother photosynthetic pigments and is almost completely white. Basedonly on this information, what assumptions can you make about ghostplants?arrow_forwardTobacco plants invest a lot of resources into the production of secondary compounds know as alkaloids (e.g., nicotine) that we believe act as defenses against herbivores. The researchers did an experiment where they added a hormone that reduces the production of alkaloids. In graph (a), the data show that the hormone reduced the proportion of alkaloids as a function of leaf mass relative to controls- so the hormone worked. They also measured the lifetime seed production of the plants in both treatments without any herbivores present (b). They had the following results. What might you conclude/hypothesize/investigate based on the data in graph (b) (a) Chemical defenses (percent of leaf mass) 1.8% 1.4 1.0 0.6 0.2 No hormone added Hormone added (b) Lifetime seed mass (g/plant) -18 14 10 No hormone added Hormone added It would be good to test whether the hormone is very specific or whether it might also cause changes in other metabolic processes The hormone has no effect on the lifetime…arrow_forwardSome plants are recognized by fungal pathogens on the basis of their stomatal pores.
