Chapter 7: Plant Form and Physiology

Multicellular Eukaryotes

Organisms with multiple cells and a nucleus

Cellulose cell wall

Plant cell structure providing rigidity and support

Photoautotrophs

Organisms that produce their own food using sunlight

Non motile

Organisms that do not move from place to place

Vascular system

Tissues specialized for transporting materials within plants

Alternation of generations

Switching between haploid and diploid life stages

Apical Meristem

Region of actively dividing cells in plant tips

Seed formation

Process of seed development for plant reproduction

Flowers

Reproductive structures in flowering plants

Vascular plants

Plants with specialized tissues for water and nutrient transport

Non-vascular plants

Plants lacking specialized vascular tissues

Bryophytes

Non-vascular plants with dominant gametophyte stage

Seedless vascular plants

Plants reproducing via spores and having vascular tissues

Tracheophytes

Plants with specialized vascular tissues for material transport

Xylem

Tissue transporting water and minerals in plants

Phloem

Tissue transporting sugars and proteins in plants

Spermatophytes

Seed plants with reduced gametophyte generation

Gymnosperms

Plants with naked seeds and exposed female gametes

Angiosperms

Flowering plants producing seeds within fruits

Double fertilization

Unique fertilization process in angiosperms

Cotyledons

Embryonic seed leaves in flowering plants

Meristematic tissue

Plant tissue responsible for growth and cell division

Permanent tissue

Mature plant tissue with specific functions
