Sexual Reproduction and Embryonic Development

Diploid

• 1 set of chromosomes (n = 23 chromosomes)

• 2 sets of chromosomes (2n = 46 chromosomes)

• 3 sets of chromosomes (3n = 69 chromosomes)

• 4 sets of chromosomes (4n = 92 chromosomes)

What is a fetus?

• The developing human organism from 9 weeks after conception to birth

• A stage of human development before conception

• A term used for a newborn baby

• A type of cell in the human body

haploid

• An organism or cell having only one complete set of chromosomes. (n = 23 chromosomes)

• An organism or cell having two complete sets of chromosomes. (2n = 46 chromosomes)

• An organism or cell that can reproduce asexually.

• An organism or cell that has no chromosomes.

What is the first stage of embryonic development after fertilization?

• Zygote

• Blastocyst

• Morula

• Gastrula

What are the key female reproductive organs?

• Ovaries and uterus

• Testes and prostate

• Fallopian tubes and cervix

• Vagina and vulva

What body system is responsible for sexual reproduction?

• Nervous system

• Digestive system

• Reproductive system

• Endocrine system

sexual reproduction

• A reproductive process that involves two parents that combine their genetic material to produce a new organism, that is different from both parents

• A method of reproduction that involves only one parent and results in genetically identical offspring

• A process where organisms reproduce by splitting into two identical parts

• A type of reproduction that occurs only in plants and involves pollination

zygote

• a haploid cell formed during meiosis

• a diploid cell resulting from the fusion of two haploid gametes; a fertilized egg.

• a type of gamete produced in the ovaries

• a cell that undergoes mitosis to form an embryo.

what is an embryo?

• It is the fertilized egg that is the early stages of the fetus.

• It is a stage of development after the fetus.

• It is a type of cell that forms in the brain.

• It is the stage of life after birth.

Why is understanding embryonic development important?

• It is crucial for grasping how new life develops.

• It helps in understanding adult diseases.

• It is only relevant for medical professionals.

• It has no impact on biological research.
