Gamete
A)not sexual
B)a reproductive cell, such as an unfertilized egg
C)an unborn, developing plant or animal
D)a long, tubular organ, like a tongue, used for sucking
E)to add pollen to the female organ of a flower
B) a reproductive cell, such as an unfertilized egg
Proboscis
A)an unborn, developing plant or animal
B)a long, tubular organ, like a tongue, used for sucking
C)not sexual
D)a reproductive cell, such as an unfertilized egg
E)to add pollen to the female organ of a flower
B) a long, tubular organ, like a tongue, used for sucking
The correct answer is B) a reproductive cell, such as an unfertilized egg.
To arrive at this answer, let's break down the options and eliminate the incorrect ones:
A) "Not sexual" is not an accurate description of gametes. Gametes are directly related to sexual reproduction, where they combine during fertilization to form a new individual.
C) "An unborn, developing plant or animal" refers to an embryo, not a gamete. Gametes are the cells involved in the process of fertilization, not the developing organisms themselves.
D) "A long, tubular organ, like a tongue, used for sucking" describes an entirely different biological structure, known as a proboscis or tongue. It is not related to gametes.
E) "To add pollen to the female organ of a flower" describes the process of pollination, but it is not the definition of a gamete. Pollen contains male reproductive cells, which are gametes themselves.
By the process of elimination, we find that B) "a reproductive cell, such as an unfertilized egg" correctly defines a gamete. Gametes are the specialized cells produced by organisms for sexual reproduction, such as eggs (female gametes) and sperm (male gametes).
