- a the root
- b interspecific relationship in which both partners benefit.
- c The densely branched network of hyphae in a fungus
- d A meristem at the tip of a plant root or in the terminal or axillary bud of a shoot.
- e A modified leaf of a flowering plant. A whorl of sepals encloses and protects the flower bud before it opens.
5 Multiple choice questions
- A specialized epidermal cell in plants that regulates the size of a stoma, allowing gas exchange between the surrounding air and the photosynthetic cells in the leaf
- -any chemical substance that promotes seeding elongation, promotes growth toward the light
- in combination with auxin, gibberellins are used to produce seedless; sprayed on on other kinds of plants, at an earlier stage, gibberellins can have the opposite effect.
- obtain some of their nutrients, especially nitrogen and minerals, by killing and digesting insects and other small animals. They grow in habitats where soils are poor in nitrogen and other minerals (acid bogs). Organic matter decays so slowly in acidic soils that there is little inorganic nitrogen available for plant roots to take up. Ex. Venus flytrap.
- contains all the essential amino acids, rich in antioxidants and fiber, low in fat, lowers LDLs and triglycerides while maintaining HDLs.
5 True/False questions
Parasitic plants → zone of cell division, zone of elongation, and the zone of maturation.
Casparian strip → A waxy barrier in the walls of endodermal cells in a plant root that prevents water and ions from entering the xylem without crossing one or more cell membranes
Function of ethylene → A heterotrophic eukaryote that digests its food externally and absorbs the resulting small nutrient molecules. Mostly decomposers, but some are parasitic. Most fungi consist of a netlike mass of filaments called hyphae. Mycelium is densely branched network of hyphae. Molds, mushrooms, and yeasts are examples of fungi.
Dicot characteristics → An outgrowth of an epidermal cell on a root, which increases the root's absorptive surface area.
Gametophyte → The multicellular diploid form in the life cycle of organisms undergoing alternation of generations; results from a union of gametes and meiotically produces haploid spores that grow into the gametophyte generation.
