Asexual and Sexual Reproduction By DeVante Moore
Advantages and Disadvantages of Sexual Reproduction
Advantages: Disadvantages: -Genetic variation -Reproduce slowly -Not all mutation passed -Is time and energy on consuming
Asexual and Sexual Reproduction Similarities
-Are important to life -Produce new cells from preexisting cells -Have a specific process of cell division
Practice Using Asexual Reproduction Terms
-The two types of reproduction are asexual and sexual. -Prokaryotes reproduce asexually through the process of binary fission. -Mitosis allows eukaryotes to grow and heal.
Thinking about Making New Cells New cells are made every second. Select every example that would involve new cells being made.
-an egg being fertilized by a sperm and developing into a zygote -a child growing -a pollen grain landing on a plant ovule that will develop into a seed
Advantages and Disadvantages of Asexual Reproduction
Advantages: Disadvantages: -Rapid reproduction -Mutations affect the -More offspring entire society of off- -Mate not needed spring. -Clones beneficial -There's no genetic to economy of agriculture variation; all offspring are identical to the parent.
How are asexual and sexual production similar and different?
Asexual reproduction generates a new identical cell through the processes of binary fission or mitosis.
Asexual and Sexual Reproduction Differences
Asexual reproduction: Sexual reproduction -No fertilization -Fertilization -No gametes -Gametes -Exact DNA as parent -Genetic variation -Prokaryotic or eukaryotic -Only eukaryotic organisms organisms -Binary fission for -Gametes through prokaryotes meiosis -Mitosis for eukaryotes -Important for -Important for reproduction, reproduction growth, and repair
Asexual reproduction
Asexual reproduction: The process of reproduction in cells without joining gametes -No gametes (male sperm and female egg) -Exact DNA as parent -Prokaryotic or eukaryotic organism -Binary fission and mitosis
Processes of Asexual Reproduction
Binary fission is the process of cell division (asexual reproduction) in prokaryotic organisms by which the parent cell divides into two genetically identical cells. -Produces two identical cells in prokaryotes
Importance to Living Organisms
Living organisms depend on asexual reproduction for life. Like for example: -growth (allows organisms to grow) -repair (replace damaged or dead cells) -reproduction (creates new organisms) -Meiosis creates gametes, sperm and egg cells, with 23 chromosomes. -Offspring have genetic variation a.recieve both genes from both parents b.cross over
Practice Using Sexual Reproduction Terms
Male and female sex cells are called gametes Which type of cell is a result of meiosis? - Haploid cells Genetic variation occurs in sexual reproduction
Process of Making Gametes for Sexual Reproduction
Meiosis is the process of two cell divisions by which one diploid cell produces four haploid cells with half the number of chromosomes as the parent cell. -The original cell is diploid, or having two sets of chromosomes. 2n is 46 -The daughter cells are haploid, or having one set of chromosomes. 23 -There are two cell division (PMAT 1 + PMAT 2) -It produces four haploid gametes.
Processes of Asexual Reproduction
Mitosis is the process of cell division by which exact copies of chromosomes are divided to create two daughter cells, each with a complete set of identical chromosomes. -Has four steps (PMAT) -Produce two identical cells in eukaryotes
The process of Meiosis
Prophase 1 Prophase 2 Metaphase 1 Metaphase 2 Anaphase 1 Anaphase 2 Telophase 1 Telophase 2
Sexual Reproduction
Sexual reproduction is the process of joining gametes, the egg and the sperm cell, for reproduction. -Fertilization -Gametes -Genetic Variation -Eukaryotic organisms -Gametes through meiosis
Contrast Asexual and Sexual Reproduction Indicate whether each is a characteristic of asexual or sexual reproduction.
sexual allows for greater genetic variation. asexual produces offspring that have the same DNA as the parent. asexual occurs in prokaryotes and eukaryotes. sexual occurs only in eukaryotes.
Identify Asexual or Sexual Reproduction
sexual reproduction four daughter cells. asexual reproduction two daughter cells. sexual reproduction meiosis. asexual reproduction mitosis. sexual reproduction genetic variation. asexual reproduction identical DNA. sexual reproduction fertlization.
