1) What does a root do? Absorbs minerals and water. 2) What consists of one main vertical root which gives rise to lateral roots? A taproot system. 3) What does the taproot system do?
Biology Gynoecium: - The gynoecium (from Ancient Greek γυνή, gyne, meaning woman, and οἶκος, oikos, meaning house) is a term with several meanings in botanical usage. In reference to mosses, liverworts and hornworts,gynoecium refers to a cluster of archegonia and any associated modified leaves or stems present on agametophyte shoot. More commonly, gynoecium refers to the ovule-producing part of a flower. The gynoecium is typically the innermost whorl of structures in a flower and is surrounded (in perfect flowers) by the androecium (stamens) and (in complete flowers) by the perianth (petals and sepals). The gynoecium is often inaccurately [clarification needed] referred to as female because it gives rise to female (egg-producing) gametophytes.

Why would add salt solution to a plant cell to help see the cell membrane? ans: Plant cells have a stiff cell wall, the cell will not appear to shrivel as an animal cell will. Instead, the cell wall remains in place, but the contents of the cell, most noticeably the chloroplasts, seem to bunch up in the center of the cell, leaving an empty space between the cell contents and the cell wall. This separation of the cell membrane from the cell wall and subsequent concentration of the cell contents is due to loss of turgor pressure inside the membrane as water moves out of the cell, toward the higher salt concentration. This process is called plasmolysis.
The cell wall protects the cell's plasma membrane. Outside the cell wall there is just a thin layer of pectin, wax and cutin to provide some padding, called the middle lamella. In some plants a secondary cell wall forms in the plants adult stages as an extra protection - this wall again is mostly made up of cellulose. Starch can be found in two forms. One is amylose an unbranched polysaccharide with 1-4 glycosidic bonds.
When glucose polymerises to become cellulose, water is eliminated and the structure becomes: The H and OH groups are omitted for clarity. It must noted that: for bonding to occur, alternate glucose units must be inverted as shown above; this bonding produces a very linear molecule due to the geometry of the rings and the C-O-C angles. * Biomass – material produced by living organisms, mainly it is plant material though it also includes animal excreta and algae material. Cellulose is the major component of plant biomass. * Cellulose as a source of chemicals – starch, another polymer of glucose, can be used as an alternative source for petrochemical products but there is more cellulose produced in plants than starch.
Chloroplast gives it the green color 15. How many of these structures are visible on the plant diagram? All Structures Part E – Plant vs. Animal Cell Compare/contrast the plant and animal cell by filling in the following graphic organizer. Use the characteristics listed in the table below.
Vegetable oil is hydrophobic and there for is not water soluble but alcohol on the other hand is completely soluble with vegetable oil. 3. We know from observing the vegetable oil and water together that the relative density of water is greater then the density of vegetable oil because the oil will always recede to the surface of water. 4. Emulsification agents allow for two unbendable liquids to be combined, the detergent hold properties that both substances can in return blend with leaving detergent dissolving in both the water as well as the alcohol unlike other substances we tried to
