Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
____ are reproductive cells that form without fertilization.
A
Spores
B
Eggs
C
Zygotes
D
Diatoms
Explanation: 

Detailed explanation-1: -spore, a reproductive cell capable of developing into a new individual without fusion with another reproductive cell. Spores thus differ from gametes, which are reproductive cells that must fuse in pairs in order to give rise to a new individual.

Detailed explanation-2: -Almost all fungi reproduce asexually by producing spores. A fungal spore is a haploid cell produced by mitosis from a haploid parent cell. It is genetically identical to the parent cell. Fungal spores can develop into new haploid individuals without being fertilized.

Detailed explanation-3: -Spore Formation is an Asexual Reproduction technique. Many Spores are housed in sacs known as Sporangia. The plants produce hundreds of spores and the spore sac bursts. These spores are dispersed into the air, where they germinate and create a new plant under favorable conditions.

Detailed explanation-4: -Answer : Fungi reproduce through spore formation; for e.g., bread moulds.

Detailed explanation-5: -Parthenogenesis is a form of reproduction in which an egg can develop into an embryo without being fertilized by a sperm. Parthenogenesis is derived from the Greek words for “virgin birth, ” and several insect species including aphids, bees, and ants are known to reproduce by parthenogenesis.
