Yes, flowers are the reproductive organ for all plants, so all plants must have them to continue their species.
No, flowers are the reproductive organs for angiosperms.
No, only nonvascular plants have flowers.
No, only plants producing spores create flowers.
Non seed plant
Reproduces by spores
Help protect flowers from pollen robbing insects
Are an adaptation that helps bryophytes produce spores for reproduction
Help to regulate water loss by controlling the size of the stomata in leaves
None of these
Can help to control erosion.
Are used by plants to store large quantities of food.
Reproduce by spores.
Contain many stoma to help absorb water.
Are seed plants
Contain "naked seeds" in cones rather than enclosed in a "fruit"
Are usually wind pollinated
All of these
Contains a pistil, but no stamen
Has both petals and sepals
Contains both a pistil and stamen
Has all four organs that we studied: flower, leaves, stems and roots
Flowers, roots, stems and leaves
Flowers with petals in multiples of 3
Flowers with petals in multiples of 4 or 5
Seeds with 1 cotyledon
Seeds with 2 cotyledons
Leaves with branching veins
Leaves with parallel veins
Water entered the cells of the leaf and the guard cells became rigid.
Water left the cells of the leaf and the guard cells became limp and closed helping the leaf to conserve water
Equilibrium was reached
There was no concentration gradient
Stolon and thorns
Adventitious roots and stolon
Thorns and spores
Root hairs and tap roots
Cannot grow more than a few centimeters in height because they cannot transport water up and down their stems
Have only one cotyledon
Are called gymnosperms
All of these
Anthers and a pistil
Stigmas and a style
An anther and a filament
A carpel and a pistil
Their cells have cell walls.
All plants are dependent upon animals (insects are included!) to spread pollen to other plants of their species to reproduce successfully.
Plants produce their own food energy through photosynthesis.
Sexual reproduction is important to a plant to increase its diversity and to increase its chances of adapting to changes in the environment.
