Chapter 11 Section 1
What is a plant?
Over 350,000 species identified
Most of life on Earth wouldn’t be possible without them
Adapted to nearly every environment on Earth
See if you can list the major parts of this plant…
Plant CellsPlants are made of cells, just like other living things
Contains chlorophyll-most plants green
Need this to make own food
controls water content of cell
Pigment are also stored here; make flowers red, blue, purple
Provides structure And
protection
jellylike material outside the cell nucleus in which the organelles are located
Controls many of the functions of the cell
PLANT CELL DIAGRAM
Plant Protection and Support• Cuticle- a waxy, protective layer on the surface
of a plant; slows loss of water(demonstration and lab)
Lab: Wax paper…. Just as the cuticle….• Cellulose- chemical compound plants can
make out of sugar; strengthens cell walls
Classification of Plants
Vascular Plants• Have tubelike structures
that carry water, nutrients, and other substances throughout the plant
Nonvascular Plants• Do not have tubelike
structures, use other ways to move water and substances
