Asexual And Sexual Reproduction Flashcards
Organisms with a ________ reproduce asexually through mitosis and name two examples
Nucleus
- Budding
- Regeneration
Organism that do not have a nucleus can reproduce by ________
Fission
A new individual develops from an outgrowth from the body of a parent and eventually splits off and lives independently
Budding
A form of asexual reproduction where genetic information is copied and the organism divides into two new identical organisms
Fission
Occurs when a body part has broken off the organism and a new one grows through mitosis
Regeneration
What is an example of fission?
Bacteria and protists
What is an example of budding?
Hydra plant
What is an example of regeneration?
Sea stars
Planaria
Sponges
A mean of asexual reproduction whereby a single parent breaks into parts that regenerate into whole new individuals
Fragmentation
Give an example of fragmentation
Flatworms or sea star
Requires two parents that each share 50% of the genetic information
Sexual reproduction
What is the female sex cell called?
Egg
What is the male sex cell called?
Sperm
When an egg and a sperm cell combine it is called _______________
Fertilization
The cell that forms when fertilization occurs is called a _______
Zygote
What are the reproductive organs of plants?
Flowers
What are the two ways sexual reproduction occurs?
Internally and externally
When the egg is fertilized by the sperm inside the female
Internal fertilization
When the egg is fertilized outside the female
External fertilization
Body cells that have body cells that have 23 identical chromosomes, or 46 total chromosomes per body cells
Diploid cells
What parts of your body do diploid cells make up?
Brain, skin, bones, and other tissues
âSingle formâ sex cells containing 23 total chromosomes
Haploid
Division of somatic(body) cells, where the nucleus divides to form two new nuclei
Mitosis
Division of gametes(sex cells) produces haploid cells when fertilization occurs
Meiosis
Chromosomes that are similar in size, in shape, and in kinds of genes
Homologous chromosomes
The process of separating the organelles and cytoplasm is called
Cytokinesis
If the organism doesnât have the right number of chromosomes, what happens?
The organism may not develop or function properly
What process makes new cells that are used during growth, development, repair, and asexual reproduction?
Mitosis
What process makes cells that enable to an organism to reproduce sexually and happens only in reproductive structures?
Meiosis
What process make two genetically identical diploid cells?
Mitosis
What process produces four haploid cells
Meiosis
When a new organism is produced from only one organism
Asexual reproduction
