Parts of a Flower and Plant Reproduction
Stem
*Connects a plant's roots to its leaves and flowers *supports the plants body *transports materials between the root system and the shoot system *some store materials (water in a cactus)
steps of pollination
1. Pollen is transferred from the anther to the stigma. 2. Once the pollen is on the stigma pollen tubes begin to grow. 3. Sperm travel down pollen tubes, into the ovule, and fertilizes the eggs. 4. Once fertilized, the ovules become seeds in the fruit. 5. Seeds are dispersed and a new flower grows. 6. The cycle starts over again.
three ways seeds can be dispersed
1. animals 2. wind 3. water
Ovules
Located in the ovary. The ovule contains an egg which developes into a seed after it is fertilized.
Stamen
Male reproductive organ of flowering plants.
Ovary
The rounded base of the pistil. It contains one or more ovules. The ovary develops into fruit.
Sepal
leaves that protect the bud
Leaf
makes food for the plant through the process of photosynthesis
flower
reproductive structure of a plant that produces pollen and seeds
What is a seed and where is it located?
A seed is a fertilized egg that is located inside the ovule which is inside the ovary.
What are the two parts that make up the stamen?
Anther and Filament
What part of the plant becomes the fruit?
Ovary
What part of the plant becomes the seeds?
Ovules
Stigma
Part of the female reproductive organ that is at the top of the pistol. The stigma is sticky to capture the pollen.
Ovary
Part of the female reproductive organ which contains the eggs
Style
Part of the female reproductive organ which holds the stigma.
Petal
Part of the flower that helps attract pollinators
Anther
Part of the male reproductive organ that is where the pollen (male sex cell of angiosperms) are produced.
anther
Part of the male reproductive structure. A saclike structure that produces pollen. Located on top of the filement.
filament
Part of the male reproductive structure. A thin stalk that holds up the anther.
Filament
Part of the stamen of the flower. Holds the anther.
gymnosperm
Plants that do not produce fruits or flowers
What is the sexual reproduction of flowers?
Pollination
What are the three parts that make up the pistil?
Stigma, Style and Ovary
petal
The broad, flat, thin leaflike parts of a flower that vary greatly in color and shape. Attracts insects or other animals to the flower.
Pistil
The female reporductive part of a flower that produces ovules that become seeds and consists of an ovary, style and stigma
Pistil
The female reproductive organ of the flower. consists of 3 main parts: stigma, style, ovary
Style
The long, slender part of the pistil. It is where pollination takes place.
Ovary
The lower part of the pistil. Where the ovules are located.
Stamen
The male reproductive part of a flower that produces pollen and consists of an anther and a filament.
Stigma
The tip of the pistil. It is where pollen grains collect.
Roots
Transports the water and dissolved nutrients/minerals in the soil to the plant's stem.
cross-pollination
a reproductive process in which pollen from one plant is transferred to the stigma of another plant
Phloem
a vascular tissue that transports food molecules down to all parts of the plant
xylem
a vascular tissue that transports water and minerals up throught the plant
sepals
the outside rings of small leaves that protect the flower when it is still a bud
Receptacle
the thickened part of a stem from which the flower organs grow
self-pollination
the transfer of pollen from the anther to the stigma on the same flower
Peduncle
top part of stem
Angiosperms
vascular plants that produce flowers and fruit to protect their seeds
