Plant divisions
Animalia- phyla
Plant-divisions
Plants can be divided into:
seed and non-seed plants OR
Vascular and non-vascular plants
![Page 11: Kingdom Plantae - conklinbiology.weebly.com€¦ · Kingdom Plantae Author: Elaine Conklin Created Date: 5/1/2014 11:45:48 AM](https://reader035.vdocuments.us/reader035/viewer/2022081411/60adda773c93f854476faf01/html5/thumbnails/11.jpg)
Plant Divisions
Non-seed plants reproduce using
spores Example- Ferns
![Page 12: Kingdom Plantae - conklinbiology.weebly.com€¦ · Kingdom Plantae Author: Elaine Conklin Created Date: 5/1/2014 11:45:48 AM](https://reader035.vdocuments.us/reader035/viewer/2022081411/60adda773c93f854476faf01/html5/thumbnails/12.jpg)
Plant Divisions Vascular plants have xylem and phloem
Non-vascular no xylem and phloem
Grow close to the ground
Found in moist environments
Example- Mosses and Liverworts

Angiosperms
Petals- brightly colored/fragrant to
attract pollinator
Sepals- leaves surrounding base of the
flower. Used to protect bud before
blossoming
![Page 18: Kingdom Plantae - conklinbiology.weebly.com€¦ · Kingdom Plantae Author: Elaine Conklin Created Date: 5/1/2014 11:45:48 AM](https://reader035.vdocuments.us/reader035/viewer/2022081411/60adda773c93f854476faf01/html5/thumbnails/18.jpg)
Angiosperms
Pistil- female reproductive
part
Stigma- top of the style, sticky
to attract pollen
Style-stalk that connects
stigma to ovary. Pollen tubes
grow down to ovary.
Ovary- egg producing
structure. Ova are made in the
ovules. Eventually develops
into the fruit.

Angiosperms
Stamen- male reproductive part
Anther- at tip. Produces pollen
Filament- long, thin stalk that supports the
anther

Angiosperms
Fertilization of a seed
Pollen is the male reproductive cells in
plants. The pollen attaches to the
stigma on the pistil. Here the pollen
begins to migrate down the style of the
pistil. When the sperm reaches the
ovary, fertilization takes place.

Angiosperms
Fertilization continued
As the seed develops, the ovary
enlarges forming the fruit. Once
dormancy ends, a seed begins the
process of development called
germination.

Plant tissues Epidermis- covers all parts of the plant
Stomata (Stomates)- openings in the
cuticle that controls exchange of gases
and prevent water loss in plants
Stomates
surrounded
by two kidney
shaped cells
called
guard cells
