Pollination
Fertilization
Germination
Photosynthesis
Self-pollination occurs within the same flower or between flowers of the same plant, whereas cross-pollination occurs between flowers of different plants.
Self-pollination involves insects; cross-pollination involves wind.
Both types involve pollen transfer from different plants.
Self-pollination occurs only in gymnosperms; cross-pollination in angiosperms.
Stamen and pistil
Petals and sepals
Leaves and roots
Stem and roots
Petals attract pollinators with their color and scent.
Petals are responsible for photosynthesis.
Petals protect the seeds from predators.
Petals store nutrients.
One sperm fertilizes the egg forming a zygote, and the other fuses with two polar nuclei forming endosperm.
Two sperm cells fertilize one egg cell simultaneously.
Double fertilization involves two flowers.
It is the fertilization of both ovary and style.
Wind-pollinated flowers lack large brightly colored petals and have long stamens and pistils.
Wind-pollinated flowers are generally larger and more fragrant.
Wind-pollinated flowers have more nectar than animal-pollinated ones.
Wind-pollinated flowers have more vivid colors.
Sepals protect the flower bud before it opens.
Sepals attract pollinators.
Sepals produce pollen.
Sepals provide nutrients to the flower.
The ovule is the structure that develops into a seed after fertilization.
The ovule is part of the stem that supports the flower.
The ovule is a component of the pistil involved in photosynthesis.
The ovule is a structure that attracts pollinators.
Seeds form when an ovule is fertilized by pollen and develops within the ovary.
Seeds form from petals after fertilization.
Seeds form in the roots of the plant.
Seeds form in the pistil after photosynthesis.
The endosperm provides nourishment to the developing embryo within the seed.
The endosperm protects the flower from predators.
The endosperm aids in pollination.
The endosperm assists in photosynthesis.
Genetic variation increases biodiversity and can improve a plant's ability to adapt to environments.
Genetic variation prevents plants from producing seeds.
Genetic variation reduces the chances of pollination.
Genetic variation is only beneficial for animals.
The pistil, which includes the stigma, style, and ovary.
The stamen, including anther and filament.
The petals and sepals.
The roots and stem.
Fruit forms from the ovary after fertilization as it contains the developing seeds.
Fruit develops from the roots of the plant.
Fruit is formed from petals after pollination.
Fruit formation occurs in the leaves of flowering plants.
A pollen tube grows from a pollen grain down the style to deliver sperm cells to the ovule.
A pollen tube is a structure in the leaf aiding in photosynthesis.
A pollen tube transports nutrients from roots to flowers.
A pollen tube is used to store pollen during winter.
Roses are typically pollinated by insects.
Oak trees, relying solely on the wind.
Cacti, which are self-pollinating.
Pines, which use birds for pollination.
