Title: Plants


1
Plants
  • Module 13

2
Plants share common characteristics
  • Photosynthetic autotrophs
  • (use the suns energy to make sugar/glucose)
  • Multicellular
  • (made of eukaryotic cells)
  • Producers
  • (are the base of the food web in ecosystems)

3
Plant Classification
  • 2 major categories
  • Non-vascular
  • (no tubes / vessels)
  • Vascular
  • (tubes/vessels for transport)

4
Plant Classification
  • Vascular plants are further divided
  • Seedless
  • (use spores for reproduction)
  • Seeded
  • (use seeds for reproduction)

5
Plant Classification
  • Seed plants are further divided
  • Gymnosperms
  • (seeds in cones)
  • Angiosperms
  • (seeds in fruits that develop from flowers)

6
STERNGRR Processes
  • Synthesis
  • Photosynthesis used to make food
  • Protein synthesis

Chloroplasts
7
STERNGRR Processes
  • Transport
  • Non-vascular plants use osmosis
  • Vascular plants have xylem to transport water and
    phloem to transport food (in vascular bundle /
    vein)

FOOD
WATER
8
STERNGRR Processes
  • Excretion
  • Tiny openings in the leaf called stomata allow
    gas exchange regulated by guard cells
  • Wastes may be stored in leaves that fall off in
    autumn

9
STERNGRR Processes
  • Respiration
  • Use oxygen and sugar to produce ATP for energy

10
STERNGRR Processes
  • Nutrition
  • Sugar produced in photosynthesis is used for
    cellular respiration or stored for later use.

11
STERNGRR Processes
  • Growth and Development
  • Seeds germinate to start the process of
    development into a new plant

12
STERNGRR Processes
  • Asexual Reproduction
  • Occurs through the process of vegetative
    propagation

13
STERNGRR Processes
  • Spores
  • Produced by non-vascular and seedless vascular
    plants for reproduction

14
STERNGRR Processes
  • Seeds
  • Found in cones in gymnosperms
  • Found in fruits that develop from flowers in
    angiosperms

15
STERNGRR Processes
  • Flowers
  • Male parts
  • Stamen - anther and filament
  • Female parts
  • Pistil stigma, style
  • and ovary

16
STERNGRR Processes
  • Flowers
  • Pollination occurs when pollen (male) is
    transferred to the stigma (female)
  • Fertilization occurs when a sperm (in pollen)
    meets egg (in ovary)

17
STERNGRR Processes
  • Regulation
  • Hormones regulate growth and control responses
    to stimuli (Ex. auxin, cytokinen, ethylene)
  • Tropisms growth responses to external stimuli
