- Monocot/Dicot seed differences-
- Function of ethylene
- Apical dominance
- Guard cells
- a Promotes fruit ripening
- b The nonliving portion of a plants vascular system that provides support and conveys xylem sap from the roots to the rest of the plant. Xylem is made up of vessel elements and/or tracheids, water-conducting cells. Primary xylem is derived from the procambium. Secondary xylem is derived from the vascular cambium in plants exhibiting secondary growth. DEAD CELLS MOVES WATER AND MINERALS UP FROM THE ROOTS.
- c number of cotyledons; hypocotyl + epicotyl vary
- d 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
- 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.

- A plant that completes its life cycle in two years
- -any chemical substance that promotes seeding elongation, promotes growth toward the light
- contains all the essential amino acids, rich in antioxidants and fiber, low in fat, lowers LDLs and triglycerides while maintaining HDLs.
- heterotrophic eukaryotes; digest food externally and absorb the nutrients; found everywhere (soil and water); mostly decomposers, some parasitic
- A study of how animals medicate themselves with plants
5 True/False Questions
Bryophyte groups → nonvascular; mosses; apical meristems; embryophytes; lack true roots/ stems; no lignified cell walls lack support; grow close to the ground; need water for fertilization
Apical meristem → A meristem at the tip of a plant root or in the terminal or axillary bud of a shoot.
Darwin's phototropism experiment → - Control
- Tip removed
- Tip covered by opaque cap
- Tip covered by transparent cap
- Base covered by opaque cap
1. Tip of shoot was responsible for sensing light
2. Growth response for the bending of the shoot occurs below the tip
3. Some signal was transmitted downward from the tip to the growth region of the shoot
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.
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.
