Cell division, or fission.

Yeast can put out small buds that separate and grow into new individuals.

Pollen grains.

The zygote divides to form an embryo within the ovule, which develops into a seed.

In the ovaries.

Barrier methods, hormonal methods, intrauterine devices, and natural methods.

Unicellular organisms often reproduce asexually, while multicellular organisms can reproduce both sexually and asexually.

By regenerating if broken into pieces and producing buds that mature into new individuals.

Blocking the vas deferens in males or the fallopian tubes in females.

Some of the immature eggs start maturing.

In the testes.

Dissolve sugar in water, add yeast, and observe the culture under a microscope.

By using a condom during sexual intercourse.

Skin frequently becomes oily and pimples may develop.

Breast size increases and menstruation begins.

A process where many bacteria and protozoa divide into two or more daughter cells.

A process where roots, stems, and leaves of some plants develop into new plants.

Increase in breast size and other physical changes.

Testes, vas deferens, seminal vesicles, prostate gland, urethra, and penis.

By splitting into two equal halves during cell division.

It results in the formation of a zygote, which can grow into a new plant.

Because sperm formation requires a lower temperature than normal body temperature.

Binary fission involves one organism splitting into two, while multiple fission involves one organism splitting into many.

It ensures that genetic information is passed on to the next generation.

Thick hair growth on the face and voice cracking.

As the rate of general body growth slows down, reproductive tissues begin to mature.

The declining female-male sex ratio.

Amoeba.

It is where the embryo is implanted and nurtured.

It provides nutrition and removes waste for the developing embryo.

Production of sperm and hormones like testosterone.

The ability of fully differentiated organisms to give rise to new individuals from body parts.

Humans use sexual reproduction.

Most bacteria may die due to increased temperatures, but heat-resistant variants may survive and grow.

A process of cell division that reduces the chromosome number by half.

Stamens and pistil.

No, it does not protect against sexually transmitted diseases.

Thick walls that protect them until they come into contact with a moist surface.

Regeneration is not a typical method of reproduction; most organisms do not rely on being cut up to reproduce.

A mode of reproduction that allows new generations to be created from a single individual.

To understand the different modes of reproduction in these organisms.

Methods such as layering or grafting.

Special lineages of cells in specialized organs that have half the number of chromosomes, achieved through meiosis.

Male gamete (motile) and female gamete (contains food-stores).

Pistil.

Unisexual (contains either stamens or pistil) and bisexual (contains both).

The penis.

Growth, where the body becomes larger.

A method where parts of plants like roots, stems, and leaves develop into new plants.

Plants can bear flowers and fruits earlier, and all produced plants are genetically similar to the parent.

It maintains body design features that allow the organism to use its particular niche.

It makes major demands on both the body and mind.

Mechanical barriers that prevent sperm from reaching the egg, such as condoms.

Puberty.

Asexual reproduction involves a single individual, while sexual reproduction involves two individuals.

The rates of birth and death in that population.

Condoms, oral pills, copper-T, and other methods.

The ovary contains ovules, each with an egg cell, which is essential for fertilization.

In a definite orientation in relation to its body structure.

Thick hair growing in new parts of the body.

Variation allows some individuals to survive changes in their niche, increasing the chances of species survival over time.

It is the process by which a seed develops into a seedling under appropriate conditions.

Because it is not necessary for maintaining the life of a single organism.

Each new generation would have twice the amount of DNA as the previous generation.

They change the hormonal balance to prevent egg release and fertilization.

To prevent pregnancy by being placed in the uterus.

It makes it harder to improve everyone's standard of living.

New plants are grown by removing tissue or separating cells from the growing tip, placing them in an artificial medium for rapid division, and then transferring to a medium with hormones for growth.

New hair-growth patterns.

A process where single-celled organisms like the malarial parasite Plasmodium divide into many daughter cells simultaneously.

It is the transfer of pollen from the stamen to the stigma of the same flower.

Testosterone.

The urethra.

Secretions that provide nutrition and facilitate transport.

Hydra and Planaria can be cut into pieces, and each piece can grow into a complete organism.

It involves two individuals and allows for genetic variation in the offspring.

To prevent unwanted pregnancies, manage family size, and for health reasons.

Pressures from friends, family, and government agencies.

Approximately nine months.

By combining genetic material from two different individuals, leading to new combinations of traits.

The transfer of pollen grains from the anther to the stigma.

Reproduction is essential for the continuation of the species and increases the number of organisms, making them more noticeable.

No, they are similar but may not be identical due to variations in the copying process.

They usually look similar to each other.

They contain information for the inheritance of features from parents to the next generation in the form of DNA.

DNA copying is accompanied by the creation of an additional cellular apparatus, and then the DNA copies separate, each with its own cellular apparatus.

The newborn cell will simply die.

Making copies of the blueprints of body design, which are encoded in DNA.

Different proteins will be made, leading to altered body designs.

Cells use chemical reactions to build copies of their DNA.
