Chapter 35: plant structure, growth, and development Flashcards
Gametophyte
Phase where the sporophyte is produced, usually haploid
Sporophyte
Asexual diploid phase in plants, dominates the life cycle in vascular plants
Vascular plants
Have phloem and xylem
Tissue
The thing that makes up organs, but is larger than just one cell
Organ
Made up of a bunch of tissues for one specific purpose
Epidermis
Outer layer of the plant in a non-woody plant
Cuticle
Waxy layer outside of the plant
Periderm
replaces the epidermis, thicker layer, wood
Stele
All of the vascular tissue on a plant
Apical meristem
Cells which form a node at the top of the terminal bud, give rise to the repetition of the nodes (responsible for primary growth)
Lateral meristem
Increases thickness of the plant (responsible for secondary growth)
Sieve tube
Thin tube which makes up the phloem
Companion cell
Supports the sieve tube by carrying out metabolism
Tracheid
Cells which make up the xylem, lack perforations in the cell wall
Vessel element
The building blocks of xylem
