Explain how the pine life cycle in Figure 30.4 reflectsthe five adaptations common to all seed plants.
In the heart embryo stage of Arabidopsis thaliana, there are three key anatomical features that are essential for plant
development. The red highlighted cells will become the
the yellow highlighted cells will become the

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_forward
- In a common eudicot pattern of development for the common bean in the figure, the radicle emerges from the seed (1), then begins to develop into a primary root that grows down into the soil. As this occurs, the hypocotyl emerges from the seed and bends into the shape of a hook (2). The bent hypocotyl lengthens and pulls the cotyledons upward (3). When the hypocotyl reaches the soil surface, exposure to light causes it to straighten (4). Primary leaves emerge from between the cotyledons and begin photosynthesis. The cotyledons typically undergo a period of photosynthesis before shriveling (5). Eventually, the cotyledons fall off the lengthening stem, and the young plant’s new leaves produce all of its food. a) Identify and explain what environmental factors influence the timing and coordination of the germination of seeds.arrow_forwardImagine that you are a member of a research group conducting research on fruit type and seed dispersal. Your group has submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document. Why is seed dispersal important in the life of plants? What would be the consequences of having seeds that simply fell to the ground underneath the parent tree? Please be detailed as possiblearrow_forwardWhat is the endosperm?

What are the major parts (and their functions) of a sunflower?arrow_forwardThe three illustrations represent the three types of relationships between the haploid gametophyte and diploid sporophyte generations found among plants. Identify the types of plants and the characteristics that belong with each of the three types of relationships. Bryophyte Ferns Seed plants ferns and horsetails mosses, liverworts, and other bryophytes Ginko biloba, spruce trees, and other gymnosperms The gametophyte requires nourishment from the sporophyte in order to survive. The sporophyte and gametophyte generations grow independently and produce differently shaped plants. The sporophyte cannot survive without nourishment from the gametophyte. Answer Bank Incorrectarrow_forwardWhich of these is a feature not present in seedless plants that have contributed to the success of seed plants on land? a. Seeds have four layers of protective tissue, the seed coat, that improve survival by providing more protection from environmental stresses. b. The reduced gametophytes of seed plants are nurtured by sporophytes and protected from stress, such as drought conditions and UV radiation. c. Seed germination is solely mediated by water during episodes of heavy rain. d. Pollen grains, with walls containing sporopollenin, deter herbivores. Three unknown non-vascular plant species were collected by Biology 3 students. Which characters BEST discriminate them from one another? 1. protonema II. special organelles III. seta IV. calyptra V. capsule VI. stalk a. I,II,III b. I,III,V c. III, IV, V d. II,IV,VIarrow_forward
