Many angiosperms reproduce both sexually and asexually
|
Sexual reproduction
flowers and formation of fruits and seeds Asexual reproduction vegetative parts: leaves, stems and roots |
Asexual reproduction
vegetative parts: leaves, stems and roots |
|
|
Asexual reproduction - leaves
|
e.g. kalanchoe
-mitosis - clone has meristematic tissue in leaf |
has meristematic tissue in leaf

|
asexual reproduction - stems
rhizomes |
horizontal underground stems
Iris and many grasses |

|
asexual reproduction - stems
tubers |
stems that are greatly enlarged due to stored glycogen. Eventually get eyes or lateral buds that reproduce

|
|
|
asexual reproduction - stems
bulbs |
short underground stems w/ numerous fleshy leaves (onions, tulips)

asexual reproduction - stems
stolons |
a.k.a. runners, horizontal above-ground stems (strawberries)
|
|
|
|
asexual reproduction - roots
suckers |
above ground stems that develop from adventitious buds on the roots
Raspberries, blackberries |

Sexual Reproduction
(FLOWERS) Capable of 4 whorls |
Outer whorls-
Sepals - generally green, function to protect bud when flower is closed Petals - colorful part of flower, function to lure animals to the flower to pick up pollen Next whorl- Stamens (male) -Anther - produces pollen -Filament - anchors anthem to flower -Pollen - male gamete |
Next whorl- Stamens (male)
-Anther - produces pollen -Filament - anchors anthem to flower -Pollen - male gamete |

Sexual Reproduction
(FLOWERS) Innermost whorl- of flower |
CARPELS or PISTILS (female)
Stigma, Style, Ovary (with gametes) |
Stigma, Style, Ovary (with gametes)

|
|
Complete –
contains all four whorls Incomplete- missing one or more whorls |
Perfect-
contains both stamens and carpels Imperfect- contains either stamens or carpels a flower may be complete but imperfect or incomplete but perfect or incomplete and imperfect or any combination |
a flower may be complete but imperfect or incomplete but perfect or incomplete and imperfect or any combination

|
FRUITS
MATURE, RIPENED OVARY Simple – develops from a single ovary of a single flower. Ex- peach, plum, avocado |
Aggregate-
from a single flower that contains many carpels. Ex-raspberry Multiple- –formed from ovaries of many flowers. Ex-pineapples |
Multiple-
–formed from ovaries of many flowers. Ex-pineapples |
|
|
FRUITS
MATURE, RIPENED OVARY Accessory - ovary and other plant tissues are used in forming fruit. Ex-strawberry |
After fertilization, embryo develops from the seeds
Under favorable conditions (sufficient light, water, ect. seeds will germinate and form a seedling |
