  1. what is the general study of plants called
  2. what is botany subdivided into
    • horticulure
    • agriculture
    • arborists
  3. what are the role of plants
    • replenish oxygen
    • food supply
    • raw materials for construction
    • medicine
  4. what are the characteristics of plants
    • eukaryotic
    • multicellular
    • autotrophic (photosynthesis)
    • non-motile
    • have cell walls made out of cellulose
    • have chloroplasts containing chlorophyll
    • store food as starch
  5. how do plants vary
    • two main groups: vascular and non-vascular
    • dominant reproductive generation(1M or 2N)
    • production of pollen spores, seeds, fruits, flowers
    • whether or not water is necessary for production
  6. define vascular
    • have tissue that conduct materials throughout the plant (xyem/phloem)
    • have true roots, stems, and leaves
    • ex) ferns, conifers, and flowering plants
  7. define non-vascular
    • no vascular system (xylem/phloem)
    • no true roots, stems, or leaves
    • ex) mosses, liverworts, hornworts, and green algae
  8. define xylem
    transports water and dissolved minerals (from the roots) within a vascular plant
  9. define phloem
    transports food (glucose) down (from the leaves) within a vascular plant
  10. explain the life cycle of plants
    • gametophyte (1N) generation: produces sex cells 'gametes'
    • during 'fertilization' a sperm cell and an egg cell unite  to form a 'zygote'
    • sporophyte (2N) generation: produces cells called 'spores' within 'sporangia'
  11. what are the two major plant groups
    • division bryophyta
    • division tracheophyta
  12. define division bryophyta
    • non-vascular
    • leafy and green 
    • rhizoids (roots absorb water)
    • needs water for reproduction
    • dominant gametophyte generation (haploid, 1N)
    • includes mosses
  13. define division tracheophyta
    • vascular 
    • true roots
    • dominant sporophyte generation (diploid, 2N)
    • includes ferns and their gymnosperms and angiosperms
    • -ferns release spores which lead to new fern formation
  14. define gymnosperms
    • naked seed
    • no need for water in reproduction, instead produce pollen
    • produce 2 types of spores
    • -microspores - male spores; become pollen
    • -megaspores - female spores; become eggs
    • include cypress, juniper, pine, fir, and redwood
  15. define leaves
    • play a role in photosynthesis
    • gas is exchanged in openings known as stomata which are controlled by guard cells
    • at night CO2 enters and O2 leaves
  16. define angiosperms
    • seeds enclosed
    • produce seeds that are inside of fruit or vegetable
    • known as flowering plants
    • reproduce sexually forming flowers, fruits, and seeds
  17. define veggie and give example
    • any plant material you eat that doesn't have to do with making new plants
    • ex)
    • carrot=root
    • celery=stem
  18. define fruit and give example
    • the product of fertilization; contains seeds
    • ex)
    • tomato
  19. what are the 5 differences between monocots and dicots
    • number of cotyledons
    • root differences
    • vascular tissue differences
    • veins in leaves
    • flower parts
  20. angiosperms vs gymnosperms
    • pollination: rely on plants and animals
    • time from pollination to fertilization: pollinate and fertilize almost simultaneously
    • fruit: produce fruit
  21. angiosperms vs gymnosperms
    • pollination:  rely on wind as their main source of pollination
    • time from pollination to fertilization: pollen can sit for 15 months or more before fertilization occurs
    • fruit: seeds without fruit
  22. why do plants have flowers
    • plants make seeds to reproduce and flowers are used to make them
    • flowers provide a place to combine genetic code from male and female into a single seed
    • plants will be the same species as the parents but not identical
  23. what are examples of pollinators
    • bees
    • flies
    • beetles
    • moths
    • humming birds
  24. what is the location and function of stamen
    • location: centrally inside petals
    • function: male reproductive organ that consists of anther & filament;produces pollen grains
  25. what is the location and function of filament
    • location: connects anther to central core of plant
    • function: stalk that supports anther
  26. what is the location and function of pollen grains
    • location: within anther
    • function: act as male gametes for fertilization
  27. what is the location and function of anther
    • location: on top of filament
    • function: produces & stores pollen grains
  28. what is the location and function of pistil
    • location: centrally inside petals
    • function: female reproductive organ that consists of stigma, style, & ovary; produces ovules
  29. what is the location and function of stigma
    • location: on top of style
    • function: adhesive surface captures pollen grains for fertilization
  30. what is the location and function of the style
    • location: connects stigma to central core of flower
    • function: stalk that supports stigma
  31. what is the location and function of the ovary
    • location: at base of pistil in central core of flower
    • function: contains ovules
  32. what is the location and function of the ovules
    • location: within ovary
    • function: sacs contain female gametes
