Reproduction Review

Looking at the diagram above, which term describes this mode of reproduction, where part of the parent sprouts smaller offspring that separate and become distinct individuals?

Many plants reproduce 1($), sprouting new plants from leaves or roots or some other part of the parent.

Another form of asexual reproduction involves 1($), which occurs when part of an organism separates from the whole, and from this piece a new individual regenerates.

In parthenogenesis, can an egg develop into an adult without being fertilized by a sperm cell?

A form of asexual reproduction that produces genetically identical offspring is known as 1($).

Certain cells undergo a special type of cell division to create gametes, called germ cells. What is this type of division called?

Gametogenesis: Two Meiotic Divisions Spermatogenesis Primary spermatocyte Meiosis I two secondary spermatocytes Meiosis II four spermatids (mature into spermatozoa) Oogenesis Primary oocyte Meiosis I secondary oocyte 1st polar body Meiosis II ootid → ovum 2nd polar body one functional egg (unequal cytoplasm division) Spermatogenesis divides cytoplasm equally, producing four equal sperm. Oogenesis divides cytoplasm unequally, producing one large egg.

Based on the diagram, how many functional sperm cells result from one primary spermatocyte after both meiotic divisions?

What term describes a life cycle, like the one shown above, in which an organism alternates between sexual and asexual reproductive strategies at different stages?

In plants with alternation of generations, haploid cells called 1($) are produced through meiosis from a diploid organism. These cells then divide by 2($), producing a haploid multicellular plant.

Do animals produce spores as part of their reproductive life cycle?

Human Male Reproductive System (Side View) Bladder Sperm duct Seminal vesicle Prostate gland Urethra Penis Testis (in scrotum) Epididymis 

Based on the diagram, what is the sac in which the testes are located called?

The production of sperm occurs inside the:

Toward the top of each testis are some coiled tubes inside which sperm is stored; this area is known as the:

When a male ejaculates, sperm moves from the epididymis through the sperm duct and is then mixed with secretions from the 1($) and 2($).

When sperm moves through the sperm duct and mixes with secretions from the seminal vesicles, the prostate gland, and Cowper's glands, it becomes known as:

Which structure passes through the length of the center of the penis?

Human Female Reproductive System (Front View) Uterus Fallopian tube Fallopian tube Ovary Ovary Cervix Vagina Vulva (external opening)

Based on the diagram, what is the passage leading from the uterus to the vulva called, sometimes referred to as the birth canal?

Which structure is a muscular organ where the embryo develops?

What is the lower part of the uterus that extends into the vagina called?

Is cloning a form of sexual or asexual reproduction?

Gametogenesis in female animals is known as:

The 1($) phase in the life cycle of most animals is the dominant stage.

Upon completion of meiosis I and meiosis II in oogenesis, the primary oocyte has developed into:

When the genetic material in the gametes unite, the union is known as:

The aggregation of cells in the ovary that releases the egg is known as a:
