What is the ecological importance (historically and presently) of seedless vascular plants? - Answer - Vascular tissue and lignin enable plants to grow tall and inhabit drier habitats - Increased terrestrial plant abundance and diversity (habitat and food resources) enables increased biodiversity and organism abundance Where do gymnosperms inhabit? - Answer Terrestrial ecosystem What are the characteristics of gymnosperms? - Answer - Cuticle and stomata* - Vascular tissue and lignin*

Review the structure of the chloroplast and know where the light reaction and the Calvin cycle take place. Ans:Light reactions take place in the thylakoid membrane of the granum. The Calvin cycle takes place in the stroma (cytoplasm of the chloroplast). The light reaction of photosynthesis begins when pigments in the chloroplast absorb light energy (photons). At the end of the light reaction, where is the energy derived from the photons stored? Ans:In NADPH and ATP which are then used...

Structure and Function in Plants and Animals - Penn Foster Self-Check Questions with Verified Solutions What is the primary function of the xylem in plants? To transport water and dissolved minerals from the roots to other parts of the plant. What is the role of the phloem in plants? To transport the products of photosynthesis, such as sugars, from the leaves to other parts of the plant. What are the three main types of plant tissues? Dermal, vascular, and ground tissues. Wh...

How does the arrangement of dermal tissues and ground tissues serve the leaves which are said to be ideally suited for photosynthesis - Answer - Epidermis is thin and transparent= allow more light to reach the palisade cells - Palisade cell layer at top of leaf= To absorb more light - Spongy layer= Air spaces allow carbon dioxide to diffuse through the leaf, and increase the surface area - The flat, thin shape of a leaf, its spongy mesophyll layer and stomata are adaptations that also all...
