Main activities a plant must perform
- transport of materials
- seed production
- food storage
why must materials be transfered?
to keep all parts of the plant alive
why is seed production important?
to continue the species
why is food storage important?
for the start of each new growing season
define cellulose
large polysaccharide molecule of glucose units that provides structure and support to the plant
how many cell walls do plants have?
2
the primary and secondary cells walls are categorized by
permeability and rigidity
the dermal tissue system is composed of
- epidermis
- cork or bark
define epidermis
single outer layer of cells
define cork/bark
several layers of empty cell wall “bricks”
the vascular tissue system is composed of
- phloem
- cambium
