- using CO2
- CO2 enters through the small openings in the leaves
- producing sugar
- high energy sugar molecules are produced and used to carry out the plants functions
- nonvascular plants
- lack system of tubes to move materials, lack roots, stems and leaves. include mosses, liverworts, and hornworts
- seedless vascular plants include,,,
- ferns, horsetails and club mosses
- vascular plants
- have specialized tissues that move materials from one part of the plant to another, have roots, stems, and leaves
- chloroplasts
- contain chlorophyll that captures energy from the sun to make food during photosynthesis
- cell membrane
- beneath the cell wall, controlls what goes in and out of the cell
- All plants are...
- multicellular, eukaryotes, autotrophs and have a cuticle
- cell wall
- supports and protects the plant cells
- cuticle
- waxy layer of the surface that keep the plant from drying out
- photosynthesis equation
- CO2 + water (in the presence of light) produce: sugar & O2
- 4 groups of plants
- nonvascular, seedless vascular, gymnosperms, and angiosperms
- photosynthesis
- the process through which all plants capture the energy from the sun and use it to make food
- using water
- water is absorbed from the soil by the plants roots
- using sunlight
- sunlight is absorbed by the chlorophyll in the cloroplasts
- Plant lifecycle
- plant produces spores, spores develop and sperm & eggs are produced (Gametophyte stage), sperm and egg join to form a zygote, zygote becomes a sporophyte
- producing O2
- O2 passes out of the plant and is released in the atmosphere
- nucleus
- controlls the functions of the cell and contain plant's DNA
- seed vascular plants include...
- non-flowering-gymnosperms (pine trees) flowering-angiosperms (sun flowers)
- vacuole
- stores water, helps support the cell and has many other important functions
