1. Adaptation‍Adaptation of a Plant: Features‍Features that allow
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
sporophyte generation. Significance:‍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)
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.

12. Phloem- the tissue in plants that carry nutrients through the plant to areas where they are needed
13.Fruit (dry with seed)

pictures handed in as a printout. Descriptions on this page. However some descriptions are just labels and don't really tell anything about the significance to plants #13,#14, #17 and #18 ( -4)
New total then is (-5) 55/60

autotroph- this is a picture of grass. it is an autotroph due to its ability to make nutrients from light (photosynthesis). they are the produces in a food chain and can make their own food.

by the way... this is a picture of a rhodedendron not a hydgrangea.

Lignin is a complex chemical compound most commonly derived from wood, and an integral part of the secondary cell walls of plants and some algae. It is one of the most abundant organic polymers on Earth. Its function is the support through strengthening of wood in trees.
Gibberellins are plant hormones that regulate growth and influence various developmental processes, including stem elongation, germination, dormancy, flowering, sex expression, enzyme induction, and leaf and fruit senescence. Without gibberellins plants would be growing, flowing, and reproducing out of control.

Bryophyte is a traditional name used to refer to all embryophytes (land plants) that do not have true vascular tissue and are therefore called non-vascular plants.
Cellulose is an organic compound with the formula (C6H10O5), a polysaccharide consisting of a linear chain of several hundred to over ten thousand linked D-glucose units. Cellulose is the structural component of the primary cell wall of green plants, many forms of algae and the oomycetes.
