Flashcards in Chapter 17 Deck (27):
Growth-producing regions of cell division found near the tips of stems and roots
a network of thick-walled cells joined into narrow tubes that extend throughout the plant body
vascular tissue made up of dead cells that form microscopic pipes conveying water and minerals up from the roots
vascular tissue consisting of entirely living cells that distributes sugars throughout the plant
Components of some cell walls that thickens and reinforces.
male and female gametes in mosses and ferns
structures in pines and flowering plants that contain the sperm-producing cells
the fertilized egg that develops into an embryo while attached to and nourished by the parent plant.
spores within protective structures
a cell that can develop into a new organism without fusing with another cell
seedless, nonvascular plants
contain lignin-hardened vascular tissues
seedless vascular plants
Have vascular tissues but no seeds. Mosses and ferns
Earliest seed plants that are not produced in specialized chambers.
Flowering plants whose seeds are in protective chambers.
alteration of generations
Where the diploid and haploid stages are distinct.
The haploid generation of the plant that produces gametes
The diploid generation that produces spores
Parts of the ovulate cone
occurs when a pollen grain lands on an ovulate scale and enters an ovule
the ovules integument
the outer layer of the floral circle
the area below the sepals
the male component of the flower
a sac at the top of the filament of the stamen
the female floral reproductive structure
