Photosynthesis Review Definition: process to convert light energy to chemical energy (glucose) that will be used to fuel the organism’s life processes Equation:
Plant Characteristics Multicellular Eukaryote Photosynthetic Roots (to anchor & absorb)
Plant Classification Characterized by tissue - Vascular or Nonvascular
Vascular Tissue Has transport tissues called xylem & phloem. Grows larger than nonvascular plants Divided into two categories: Seedless Vascular Vascular Seed
Seedless Vascular Usually contain spores If no spores present, then needs water for reproduction Examples: Ferns Horsetails Club Mosses
Club Mosses - Epiphytes Epiphyte: Plant that lives anchored to another plant (not parasitic)
Vascular Seed Uses seeds as mechanism for reproduction No longer dependent on water for reproduction Examples Gymnosperm Angiosperm
Seeds Seed Categories: divided by seed leaves called cotyledons One seed leaf – monocot Two seed leaves – dicot Adaptations for dispersal Ex) Spikes – cling to fur Ex) Wings – catch the wind
Monocot vs Dicot
Seed Adaptations for Dispersal
Gymnosperm Characteristics “Naked Seeds” Do not produce flowers or fruit Usually use cones for reproduction Adaptation for land: needle- like leaves to reduce water loss
Gymnosperm Examples Conifers (cone bearing plants) Cycads Gingkoes Gnetophytes
Angiosperm Characteristics Flowering Plants Produce Fruit Make up 75% of the Plant Kingdom
Angiosperm Lifespan Annual – one growing season Biennial – 2 years Perennial – several years
