Cones
The reproductive structures used by cycads.
Cycads, Ginkgo, Flowering Plants, or Conifers
Which seed plants are not gymnosperms?
Flowering Plants
Which of the seed plants are also known as angiosperms? Gnetophytes, Flowering Plants, Conifers, or Cycads
Ovulate cone
Which of the following structures is not a diploid? Mature sporophyte, seedling, ovulate cone or mature seed on cone scale
Zygote
Which of the following structures is not haploid
Cones less than 1/2" diameter
Which of the following characteristics would not be included in a botanist's descriptoin of a Cypress tree if using a dichotomous key: Cones less than 1/2" diameter, cones woody, cones rounded, most leaves are not sharp.
Incense Cedar
Of the following trees, which one does not have rounded cones and most of the leaves are not sharp? Juniper, Cypress, Incense Cedar, or White Cedar.
The zygote grows into an embryo
True of reproduction in a pine tree.
Angiosperm
A flowering plant that makes seeds inside of a fruit is a(n)
Gametophyte

Sporophyte.
In seed plants, the sperm make it to the egg via ....
Pollen tubes.
Seeds provide plant offspring with the following advantages...
Nourishment of the embryo; dispersal of the plant; protection of the embryo.
The seeds of plants contain
embryos
Stigma, Ovary, Ovule
Female part of the flower
Pollen
Male part of the flower
Embryo
Inside a seed the new sporophyte is a(n)...
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
Angiosperm
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
Perfect flower
A flower that only contains male or only female anatomy is called an
Imperfect flower
Parts of a perfect flower are
stigma, style, ovary, petal, anther, filament and sepal
Pistil
stigma, style and ovary
Stamen
Petal, anther, filament & sepal
Pollination
The transfer of pollen from the anther to the stigma
When the pollen grain makes contact with the stigma, it starts to grow a
pollen tube.
Fertilization occurs when
the sperm meets the egg in the ovule
Pollinators
Organisms that transfer the pollen from one plant and place it on another plant.
Bees, butterflys, lady bugs and animals
Common pollinators.
Seed Dispersal
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.
Dicot Angiosperms
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.
Tap Root
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.
Fibrous roots
Small, extensively branched roots. Stay close to the surface but cover a wide area of soil. Monocots most often have fibrous roots.
Veins
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.
Phloem
Transports the nutrients, including the glucose made in the leaves, and flows both up and down the length of the plant.
