plants reproduction Juan Jose Murcia
the plants reproduced by pholem
Plants reproduce thanks to pollen, that is, some animals, such as insects, butterflies, etc., take it to other plants, but they do not take everything because the plant continues to regenerate pollen and because of that, it never ends.
why the animal help a plant in reproduction
Insects help plants reproduce because they have nectar that attracts insects and when they step on the plant they take the pollen and go from plant to plant
the process of reproduction plants
Sexual
Sexual reproduction: In this process, the plant produces sexual organs (flowers) that contain male and female gametes (sex cells). Pollination is the mechanism that allows gametes to unite and form a zygote. The zygote then develops into a seed that carries the genetic potential of a new plant. This seed disperses and, under the right conditions, germinates and grows to become a new plant.
disadvantages
Genetic Variability: Sexual reproduction creates genetic variation in offspring, which increases the chances that some plants will have traits that make them more resistant to environmental changes or disease.
Improved adaptability: The genetic variability produced by sexual reproduction is essential for plants to adapt to new challenges and environmental changes over time.
advatages
Speed of propagation: Asexual reproduction allows plants to reproduce quickly and produce offspring identical to the mother plant. This is especially useful when you need to increase the population of a specific plant quickly.
Preservation of desirable characteristics: Asexual reproduction ensures that the desirable characteristics of a mother plant are faithfully transmitted to her offspring, since there is no mixing of genes. This is valuable when particular characteristics are desired in new plants.

Division of rhizomes or bulbs: Some plants have rhizomes or bulbs that can be divided into smaller parts, each of which can grow to form a new plant.
Cuttings: A part of the plant (for example, stems, leaves or roots) is cut and placed in a suitable medium so that it develops roots and develops into a new plant.
Asexual Reproduction: In asexual reproduction, plants generate offspring without the involvement of gametes. There is no seed formation in this process. Some common methods of asexual reproduction in plants are:
advantages
Asexual reproduction has the advantage that a large number of offspring can be produced quickly and without the need to find a mate for pollination. However, sexual reproduction allows greater genetic variability, which can be beneficial for plant adaptation to environmental changes.
disadvantages
Lack of genetic variability: Asexual reproduction produces offspring genetically identical to the parent plant, which can be a disadvantage if the environment changes or if pests and diseases appear to which the parent plant is susceptible.
Increased vulnerability to disease and environmental changes: Lack of genetic variability in offspring can make the entire population vulnerable to the same diseases or environmental challenges
Sexual reproduction by Simón Rojas Herrera
What is sexual reproduction
Sexual reproduction is a biological process by which two organisms of the same species contribute their genetic material to create a new individual.
How is the process
This process involves the union of specialized sex cells, called gametes, from two different parents: one male and one female.
In most species, including humans, the male gametes are called sperm and the female gametes are called ova.
Consequences of the sexual reproduction
Some consequences are that sexual diseases can be transmitted, which are more than 30 diseases, and on the basis of reproduction can affect overpopulation in the world.
Pros
sexual reproduction offers advantages in terms of adaptability, evolution, disease resistance and genetic diversity, which contribute to the survival and successful evolution of species in changing environments.
Which species can do it
Animals: Most animals, including mammals, birds, reptiles, amphibians, fish, reproduce sexually. Humans also fall into this category and reproduce sexually.
What is it?
Contraceptive methods are various techniques and devices used to prevent unwanted pregnancies.
Different types of birth control methods
Male and female condoms and diaphragms, which block sperm from reaching the egg.
Emergency contraception, also known as the morning-after pill, is used after unprotected sex to reduce the risk of pregnancy.
Hormonal methods, which include types of birth control pills, patches, injections and implants. They work by altering hormone levels to prevent ovulation or fertilization.
What are the most effective methods?
The most effective methods are implants and IUDs.
What is DIUs and Implants?
It is a small T-shaped plastic device that is used as a contraceptive. It is placed in the uterus and prevents pregnancy.
It is a very small, thin rod about the size of a matchstick. The implant releases hormones into your body that prevent pregnancy.
Human reproduction by Maria Paula Baquero
How occurs?
The process of human sexual reproduction occurs through the union of the gametes (sex cells) of a male with that of a female.
In the case of women the gamete would be the ovules and for men it would be the testicles.
When occurs?
This process occurs when, after ejaculation, the sperm fertilizes the ovum and fuses its nuclei as well as combining the genetic material. This creates a zygote which will begin to divide to form an embryo which will develop in the lining of the uterus.
Chromosomes
Each member contributes 23 chromosomes of its genetic material, so the combination of these chromosomes makes the new organism have 46 chromosomes.

diseases
what is ?
most dangerous sexually transmitted diseases
Human Immunodeficiency Virus (HIV)
Human Papillomavirus (HPV)
Chlamydia.
gonorrhea
counteracting the diseases
to counteract and not to have sexual diseases you should use a condom before having sex and change it every now and then only have contact with one person.
diseases are described as health deviations and sexual diseases are diseases that are very difficult to counteract there are more than 30 diseases and you can have them for life.

Asexual Reproduction
What is?
What's the process?
It have a LOT of different process, but for example:
The process of fragmentation only occurs in asexual reproduction and it consists in theconsists of a main organism dividing into fragments that form a new individual.
Which of the living things can have an asexual reproduction?
Organisms that reproduce in this way are prokaryotic organisms, such as bacteria,eukaryotic organisms...
And also such as plants and fungi among many others including pathogens
In sexual reproduction it is necessary to support living beings to give rise to a new individual.
This new individual contains half of the genetic information of the father and half of the genetic information of the mother...
Therefore the new living being is different from its parents, this is called genetically appropriate.
