Organisation of plant tissues Flashcards
What is structures of sclerenchyma?
Thickest cell wall
Have dead cells
What is structures of xylem?
Have dead cells
Cell wall made up of ligninXylem vessels are hollow and elongated
What is function of xylem?
Transport water and mineral salts
What are the types of plant tissues?
Meristematic and Permanent
What is the structures of epidermal tissues?
Layers outermost leaves, stems and roots of young plants
Have waxy and waterproof layers called cuticle
What is the branches of permanent tissues?
Epidermal
Ground
Vascular
What is functions of collenchyma?
Provides mechanical support and elasticity
What is structures of collenchyma?
Thicker cell wall
Cell wall made up of pectin and hemicellulose
What is the functions of sclerenchyma?
Transport water and nutrients
Provides support and mechanical strength
What is function of phloem?
Transport sugar produced from photosynthesis
What is structures of sclerenchyma?
Thickest cell wall
Have dead cells
What is function of parenchyma?
Storage of sugar and starch for photosynthesis
Regeneration of plant via vascular system
What is structures of parenchyma?
Thinnest cell wall
Turgid state
What is the types of meristematic tissues?
Apical and Lateral
What is structures of phloem?
Made up of companion cells and sieve tubes
Sieve tubes elongated and continuous
