autotroph
organisms which make their own food through photosynthesis
3 organelles found only in plant cells
central vacuole, cell wall, chloroplasts
vascular tissue
system of tubelike cells that transport water and nutrients
vascular tissue that brings water up from the ground into the plant
xylem
vascular tissue that brings sugars throughout the plant
phloem
3 ways seeds are spread
wind animals water
bryophyte
nonvascular seedless plants
moss v or nv
nonvascular
rhizoids vs roots
