3. Thigmotropism- touch
4. Hydrotropism- water
5. Chemotropism- chemicals
- b A study of how animals medicate themselves with plants
- c 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.
- d - A flowering plant whose embryos have a single seed leaf, or cotyledon; parallel veins; vascular bundles are scattered; petals in multiples of 3; fibrous root system.
- e mosses; ferns; most plants have it
5 Multiple choice questions
- number of cotyledons; hypocotyl + epicotyl vary
- - Need a long continuous (14 hrs) dark period to flower
- Will not flower if dark period is interrupted by even a brief flash of light
- Not affect if daytime period is broken by a brief exposure to darkness
- Flower in early spring, late summer, fall

5 True/False questions
pistil → Part of the reproductive organ of an angiosperm, a single carpel or a group of fused carpels.
Apical meristem → A meristem at the tip of a plant root or in the terminal or axillary bud of a shoot.
mycorrhiza → The binding together of like molecules, often by hydrogen bonds
Lichen → A close association between a fungus and an alga or between a fungus and a cyanobacterium, some of which are known to be beneficial to both partners.
Parasitic plants → 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.
