between the nodes. The stem is responsible for elongation of the plant and acts as a central axis for other organs to attach to. The roots help to anchor the plant as well as absorb water and nutrients from the soil. In addition‚ roots often form mycorrhizae with fungi‚ providing further advantage. Some roots are specially designed to store nutrients for later use of the plant. Leaves are wide flat regions that grow off of the stem. Their primary purpose is to add surface area for photosynthesis.

Campbell’s Biology‚ 9e (Reece et al.) Chapter 31 Fungi Though fungal divisions have traditionally been based on modes of sexual reproduction‚ molecular considerations are becoming more important. Consequently‚ no emphasis has been placed on the vagaries of sexual and asexual reproduction among various fungi in this Test Bank. Instead‚ new questions assess students’ abilities to think logically about fungal morphology‚ genetics‚ and ecology. Two new sets of scenario questions deal with the biology

DOLP- Fungi General Structure and Function: For many years‚ fungi were classified into the plantae kingdom because the two kingdoms seemed to be alike; but now‚ we know that they are all too different. In fact‚ the fungi kingdom is more closely related to the animalia kingdom. Some of the only notable similarities between the fungi and plantae kingdoms are that they are both made of eukaryotic cells‚ both immobile‚ both contain cell walls (although made of different material)‚ and both evolved
