    Study Notes

    Plant Characteristics

    • All plants are multicellular, eukaryotic organisms that are photosynthetic autotrophs. They have chloroplasts, which are organelles that contain chlorophyll, a pigment that captures light energy for photosynthesis.
    • Plants are adapted to life on land and have evolved characteristics such as a waxy cuticle, stomata, and vascular tissue to survive in terrestrial environments.

    Photosynthesis in Eukaryotes

    • Photosynthesis in eukaryotes likely evolved through endosymbiosis, a process where one organism lives inside another.
    • Endosymbiosis involved a eukaryotic cell engulfing a prokaryotic cell capable of photosynthesis, establishing a symbiotic relationship where both organisms benefit.
    • Photosynthetic organelles, such as chloroplasts, are found in various types of eukaryotic organisms, including plants, algae, and some protists.

    Plant Evolution

    • The endosymbiotic process involving cyanobacteria is the evolutionary origin of photosynthesis in eukaryotes.
    • The photosynthetic organelles in eukaryotic organisms are remnants of the prokaryotic cells that were incorporated through endosymbiosis.
    • All photosynthetic eukaryotes have chloroplasts, which are derived from ancient cyanobacteria acquired through endosymbiosis.
    • This process of endosymbiosis is a key example of how complex eukaryotic cells evolved from simpler prokaryotic ancestors.

    Plant Groups

    • Bryophytes
      • Lack vascular tissue and roots.
      • Reproduce predominantly through spores.
      • Tolerate drying out by having a limited cuticle.
      • Dominant form is haploid.
    • Ferns
      • Have vascular tissue and roots, but do not produce seeds.
      • Reproduce through spores.
      • Dominant form is diploid.
    • Gymnosperms
      • Have vascular tissue, seeds, and woody stems.
      • Seeds are not enclosed within a fruit.
      • Dominant form is diploid.
    • Angiosperms
      • Have vascular tissue, seeds, flowers, and fruits.
      • Seeds are enclosed within a fruit.
      • Dominant form is diploid.

    Plant Structures and Functions

    • Cuticle
      • Waxy layer on the surface of leaves and stems
      • Prevents water loss by reducing evaporation.
    • Stomata
      • Microscopic pores on leaves and stems
      • Allow for gas exchange (CO2 uptake, O2 release), facilitating photosynthesis and respiration.
    • Vascular tissue
      • Xylem and phloem
      • Xylem transports water and minerals from roots to leaves.
      • Phloem transports sugars and nutrients from leaves to other parts of the plant.
    • Meristems
      • Localized regions of actively dividing cells
      • Responsible for growth and development.
      • Typically found at the tips of roots and stems (apical meristems) and in lateral buds (lateral meristems).
    • Root
      • Anchors the plant in the soil and absorbs water and minerals.
    • Stem
      • Supports the plant and transports water and nutrients.
    • Leaf
      • The primary site of photosynthesis.

    Plant Adaptations

    • Secondary growth
      • Stems of woody plants thicken over time due to lateral meristems, contributing to increased girth.
    • Reproduction
      • Alternation of generations, cycling between haploid (gametophyte) and diploid (sporophyte) stages.
    • Seed dispersal
      • Wind, water, or animals play crucial roles in dispersing seeds, promoting plant distribution.
    • Pollination
      • Angiosperms rely on various pollinators, such as insects, birds, or bats, for the transfer of pollen from the male part (anther) to the female part (stigma) of the flower, allowing for fertilization and seed production.

    Plant Distinguishing Features

    • Monocots
      • One cotyledon (seed leaf)
      • Parallel leaf venation
      • Scattered vascular bundles in stem.
    • Eudicots
      • Two cotyledons
      • Net-like leaf venation
      • Vascular bundles arranged in a ring in the stem.
