plant anatomy

Plant Kingdom

eukaryotic, autotrophic

How plants make their own food

photosynthesis

formula for photosynthesis

6H20 + 6CO2 —> C6H12O6 + 6O2

transpiration

the process where plants release water vapor into the atmosphere, primarily through the stomata on their leaves, stems, and flowers.

cambium

a tissue located between the xylem and the phloem (in the stem)

xylem

a vascular tissue that transports water upward from the roots to the rest of the plant

phloem

vascular tissue that transports sugar (food) produced in photosynthesis down from the leaves to the roots

tracheophytes

land plants with specialized tissues that transports water, minerals, and food throughout the plant (more complex)

-are taller

bryophytes

small, green, non-vascular land plants that lack roots and vascular tissue (simpler)

plant reproduction

participate in asexual and sexual reproduction

gymniosperms

plants that do not bear fruit

angiosperms

bear fruit and have flowers

monocot

simple angiosperm, not veiny

dicot

more complex angiosperm

-is veiny

pistil

the female reproductive organ of a flower

-responsible for producing and protecting ovules

-receives the pollen during fertilization

-includes the ovules, ovary, style, and stigma

egg (ovule)

reproductive cell that will become the seed when fertilized by pollen

ovary

-houses the ovules

style

a tube that connects the ovary and the stigma

stigma

receives the pollen durning fertilization

petals

attracts pollinators to the flower

sepal

small leaves under the flower that protect the outer covering of the flower

stamen

the male reproductive organ of a flower that consists of the filament and the anther

filament

holds the anther

anther

produces and contains pollen

cuticle

waxy outer layer under the leaves that prevents water loss

stomata

opening for gas exchange on the surface of leaves and stem, is open at night to prevent water loss

guard cells

opens and closes the stomata
