What is reproduction in organisms?
The process by which organisms produce their offspring similar to themselves
What are the offspring produced in asexual reproduction referred to as?
Clones
What is a characteristic of asexual reproduction?
Involves only mitosis
Which mode of asexual reproduction involves the division of the parent body into two equal halves?
Binary fission
What is the main purpose of reproduction in living organisms?
To maintain population and ensure species continuity
In sexual reproduction, how are offspring produced?
By a single parent without fusion of gametes
Which type of reproduction involves the fusion of gametes from two parents?
Sexual reproduction
What are the microscopic motile structures called in which members of kingdom fungi and simple plants reproduce?
Zoospores
How are new offspring produced through vegetative propagation?
Through the development of vegetative propagules
What is the phase called in which organisms reproduce sexually?
Reproductive phase
Which type of plant lives for one year and starts flowering at the end of the year?
Annual plants
What is the term for mammals that actively reproduce throughout their reproductive phase?
Continuous breeders
Which type of reproductive cycle occurs in primates?
Menstrual cycle
What are the structures that give rise to new offspring through vegetative propagation?
Vegetative propagules
Which plant lives for several years but flowers only once in its lifetime?
Perennial plants
What is the term for the phase between reproductive maturity and death of an organism?
Senescent phase
Match the reproductive structure with the organism it is associated with:
Conidia = Penicillium Buds = Hydra Gemmules = Sponge Zoospores = Chlamydomonas
Match the vegetative propagule with the plant it originates from:
Runner = Strawberry Rhizome = Ginger Suckers = Chrysanthemum Bulb = Onion
Match the plant type with its description:
Annual plants = Live for one year and start flowering at the end of the year Biennial plants = Live for two years and start flowering in the second year Perennial plants = Live for several years but flower only once in their lifetime Bamboo species = Flower only once in 50-100 years
Match the mammal reproductive behavior with the category it belongs to:
Seasonal breeders = Cow, buffalo Continuous breeders = Man, rabbit
Match the plant part with the vegetative propagule it gives rise to:
Eyes of potato = New potato plants Rhizomes of banana = New banana plants Adventitious buds of Bryophyllum = New Bryophyllum plants Modified stem nodes of ginger = New ginger plants
Match the mode of asexual reproduction with its description:
Binary fission = The parent body divides into two equal halves and each half grows into an adult Budding = Small bud is produced due to cell division at one particular site, which remains attached initially to the parent cell and eventually gets separated and matures into a new individual Parthenogenesis = Development of an embryo from an unfertilized egg Fragmentation = Breaking of the body into several pieces, each of which can grow into a new individual
Match the type of reproduction with its characteristic:
Asexual reproduction = Involves only mitosis Sexual reproduction = Involves fusion of gametes from two parents Parthenogenesis = Offspring are genetically and morphologically similar to the parent Fragmentation = Rapid multiplication
Match the type of reproduction with its example organism:
Binary fission = Amoeba Budding = Yeast Parthenogenesis = Some species of lizards and birds Fragmentation = Flatworms
Match the characteristic with the type of reproduction:
Single parent involved, no fusion of gametes = Asexual reproduction Development of an embryo from an unfertilized egg = Parthenogenesis Offspring are exact copies of their parents = Asexual reproduction Involves fusion of gametes from two parents = Sexual reproduction
Match the organism with its mode of asexual reproduction:
Amoeba = Binary fission Yeast = Budding Flatworms = Fragmentation Hydra = Budding
