This is a picture of a flower, inside of the flower is the Stigma and style of carpel. In this picture, the carpel is the purple part in the inside of this flower. The carpel is the female sex part of the flower. The stigma, which is the top part of the style, is where pollen germinates. And the style, which is the middle part of the carpel, is where the pollen tubes grow.
This is a picture of a bee on a flower. The relationship between a bee and a flower is an example of Mutualism. Mutualism is when two organisms of different species have a relationship in which both organisms benefit from each other. In this picture, the flower is helping the bee by providing food for the bees family, and the bee is helping the flower by carrying pollen from one flower to another, pollinating it.
This is a picture of a red impatiens flower and a white impatiens flower, which are examples of Dominant and recessive phenotypes. A phenotype is the way something looks, and the red impatiens flower has either one or two dominant alleles making it have a dominant phenotype. And the white impatiens flower must have two recessive alleles, giving it a recessive phenotype.
