- Benefits of soy
- types of seed dispersal
- root pressure
- Apical dominance
- a - osmotic pressure caused by the buildup of solutes in the xylem of roots; root xylem up solutes, down water, therefore water in soil diffuses into root; pressure in root xylem forces water up through stem xylem
- b A plant that completes its life cycle in a single year or growing season.
- c fruit, wind, animals
- d contains all the essential amino acids, rich in antioxidants and fiber, low in fat, lowers LDLs and triglycerides while maintaining HDLs.
- e In a plant, the hormonal inhibition of axillary buds by a terminal bud. Concentrating resources on growing taller, it is an evolutionary adaptation that increases the plant's exposure to light.
5 Multiple Choice Questions
- mosses; ferns; most plants have it
- Light-colored, water-conducting secondary xylem in a tree
- plant roots + fungus= symbiotic relationship; mutually beneficial associations of plant roots and fungi, are common and may have helped the first plants adapt to land
- - the collection of cells, organisms, or molecules resulting from cloning; also (colloquially), a single organism that is genetically identical to another because it arose from the cloning of a somatic cell
- A life cycle in which there is both a multicellular diploid form, the sporophyte, and a multicellular haploid form, the gametophyte; a characteristic of plants and multicellular green algae.
5 True/False Questions
Zone of maturation → root cells elongate, sometimes to more than ten times their original length; it is cell elongation that pushes the root tip farther into the soil; the cells lengthen, rather than expand equally in all directions, because of the circular arrangement of cellulose fibers in parallel bands in their cell walls. The cells elongate by taking up water and the cellulose fibers separate
capillary action → - the tendency of liquid to rise inside a narrow tube; xylemnarrow, capillary-type tubes, strong attraction between water and the cell walls; several centimeters.
stomata → The sticky tip of a flower's carpel, which traps pollen grains
Angiosperm male/female gametophyte → The multicellular haploid form in the life cycle of organisms undergoing alternation of generations; mitotically produces haploid gametes that unite and grow into the sporophyte generation
Dicot characteristics → A term traditionally used to refer to flowering plants that have two embryonic seed leaves, or cotyledons; branched veins; vascular bundles arranged in a ring; petals in multiples of 4 or 5; taproot.
