In gymnosperms the female cones produce
Ovules and seeds.
Structures directly involved in sexual reproduction are
Stigma and style; Anther and pollen grains; and ovule and ovary.
Flowering plants that reproduce through seeds that are contained in fruit
Flower of a plant can contain...
male anatomy, female anatomy and sterile structures.
A plant that contains both male and female anatomy is known as a

Parts of a perfect flower are
stigma, style, ovary, petal, anther, filament and sepal
stigma, style and ovary
Petal, anther, filament & sepal
The transfer of pollen from the anther to the stigma
When the pollen grain makes contact with the stigma, it starts to grow a
Fertilization occurs when
the sperm meets the egg in the ovule
Organisms that transfer the pollen from one plant and place it on another plant.
Bees, butterflys, lady bugs and animals
Seeds dispersed away from the parent plant.
Wind, water & animals
Ways seeds are dispersed away from the parent plant.
Monocots and Dicots
Angiosperms are broken into two groups. They are...
Monocot Angiosperms have...
1 cotyledon, parallel veins, flower parts in multiples of 3 and scattered vascular bundles throughout the stem. Examples are corn and grasses.
contain 2 cotyledons, have a network vein pattern in their leaves, have flower parts in multiples of 4 or 5 and have their vascular bundles in a ring around the edge of the stem. Examples are roses and maple trees.
A long, main primary root with smaller roots branching off the tap root. Have the ability to grow deep into the ground. Dicots most often have tap roots.
Small, extensively branched roots. Stay close to the surface but cover a wide area of soil. Monocots most often have fibrous roots.
transport water and nutrients in a plant.
Xylem of the vein
transport the water and it only flows up from the roots to the rest of the plant.
Transports the nutrients, including the glucose made in the leaves, and flows both up and down the length of the plant.
