1. Adaptation of a Plant:Features that allow a plant to live in a certain habitat or climate.These adaptations have evolved over extremely long periods of time. Significance: The existence of adaptations make it possible for plants to live in the climates and habitats that they do.
2. Abscisic Acid: A plant hormone that slows down growth. It promotes seed dormancy and facilitates drought tolerance.Significance: It is significant because it triggers the stomates to close when there is less water for transpiration.
3. Anther & Filament of Stamen:Anther- In angiosperms, the pollen sac of a stamen where pollen grains with male gametes form. Filament- the stalk of the stamen. Significance: This is how plants reproduce. The anther releases pollen to the outside of the anther and it brushes against insects. The filament helps by extending the anther out so it is easier for the insects to access.
4. Ethylene: The only gaseous plant hormone. Effects are- response to mechanical stress, leaf abscission, fruit ripeninig, and programmed cell death. Significance: The hormone is significant because it can induce fruit ripening
5. Gametophyte; Exits in organisms that are undergoing alteration of generations. Is the multicellular haploid form that produces haploid gametes that unite and grow into sporophyte generation. Significance:
6. Gibberellins: A class of related plant hormones that stimulate growth in the stem and leaves, trigger the germination of seeds and breaking of bud dormancy, and stimulate fruit development with auxin. Significance: This hormone is important because it is resposible for seed germination and early plant development.
7. Sporophyte: A phase in plants where a diploid plant body grows and eventually produces spores through meiosis. Each spore then carries chromosomes as singles, which then develop into the gametophyte generation. Significance: This "generation" of plants is the most commonly seen generation. It carries its chromosomes in doubles (diploid)
8.Xylem: Secondary cell walls in a plant that are in a coil shape so that it can stretch. It is involved with the transport of water in plants. Significance: it is used to transport water and nutrients through a plant.
9.Auxin producing area of a plant: It is produced in the apical meristem. Auxins are plant hormones which play significant roles in numerous plant activities. Significance: Auxin contributes to cell differentiation
10. Pteriophyte: A vascular plant that lacks flowers or seeds. They reproduce using only spores. A normal pteriophyte is a diploid sporophyte. Significance: This is significant because it deals with how some plants reproduce.
11. Conifer Leaf- leaf of a plant that stays on year round
12. Phloem- the tissue in plants that carry nutrients through the plant to areas where they are needed
13.Fruit (dry with seed)
14. Fruit (fleshy with seed)
15. Deciduous Leaf- leafs of plants that fall off when the weather is unsuitable for the leaves.
16.Autotrophs- The producers in a food chain. They are able to make their own food, and support the entire food chain.
17. Short day plant (coffee)
18. Long day plant (lettuce)
19. Thorn- A plants defense against predators
20. Genetically Modified Organism (GMO)- Onions like this are genetically modified to produce less tears.
