Answer (1 of 4): Well since it doesnt require a partner, the budding method of reproduction can help the cell reproduce faster. Two basic methods of plant propagation exit; sexual and asexual. Overall, cells are in low numbers in many natural environments. Produces identical quality as the parent.

The process of sexual reproduction introduces variation into the species because the alleles that the mother and the father carry are mixed together in the offspring. A disadvantage is that sexual reproduction takes longer than asexual reproduction.

Advantages of Reproduction Asexual Good qualities from parents are retained in the offspring without variation. New individuals produced asexually mature faster. Process does not depend on external factors which may fail such as pollination.

The asexual reproduction is not complex, It requires less energy compared to the sexual reproduction, and there is no need for much time or energy to produce the offspring, so, the plants can produce many offspring without considering the amount of time or energy to consume.

The major disadvantages of asexual reproduction are: Lack of diversity. Since the offsprings are genetically identical to the parent they are more susceptible to the same diseases and nutrient deficiencies as the parent. All the negative mutations persist for generations.

Some plants can produce seeds without fertilization via apomixis where the ovule or ovary gives rise to new seeds. Advantages of asexual reproduction include an increased rate of maturity and a sturdier adult plant. Asexual reproduction can take place by natural or artificial means.

List of Advantages of Asexual Reproduction

• It allows for rapid populating.
• It does not require mobility.
• It does not need mates.
• It is friendly to the environment.
• It is pretty handy in case of emergency.
• It does not require any true investment.
• It hinders diversity.
• It poses some inheritance issues.

Some of the asexual methods are binary fission (e.g. Amoeba, bacteria), budding (e.g. Hydra), fragmentation (e.g. Planaria), spore formation (e.g. ferns) and vegetative propagation (e.g. Onion).

Guys start producing spermatozoa (or sperm, for short) at the onset of puberty. Puberty starts at different times for different people. Boys usually start puberty when they’re around 10 or 12 years old, though some start a little sooner and others a little later.

Peak and Decline Researchers found that semen quantity peaked between the ages of 30 and 35. (Could this be nature’s way of making sure a couple conceives before female fertility starts to decline at age 35?) On the other end of the spectrum, overall semen quantity was found to be lowest after age 55.

Teens are at a higher risk for pregnancy-related high blood pressure (preeclampsia) and its complications than average age mothers. Risks for the baby include premature birth and low birth weight. Preeclampsia can also harm the kidneys or even be fatal for mother or baby.

Experts say the best time to get pregnant is between your late 20s and early 30s. This age range is associated with the best outcomes for both you and your baby. One study pinpointed the ideal age to give birth to a first child as 30.5. Your age is just one factor that should go into your decision to get pregnant.

3 in 10 teen American girls will get pregnant at least once before age 20. That’s nearly 750,000 teen pregnancies every year. Parenthood is the leading reason that teen girls drop out of school.

The Conversation

1. First, find the words. You might say, “I have something difficult to tell you.
2. Be prepared to deal with the reaction. What happens next?
3. Give your parents time to speak without jumping in. Listen to what they say.
4. Tell them how you feel.
5. If you need to, get help breaking the news.

Pregnancy Testing and Counseling Under most circumstances, a doctor won’t reveal to you that your child took a pregnancy test. Instead, the doctor will talk to your teen about her options and inform her of her rights in your state.

The most common early signs and symptoms of pregnancy might include:

• Missed period. If you’re in your childbearing years and a week or more has passed without the start of an expected menstrual cycle, you might be pregnant.
• Tender, swollen breasts.
• Nausea with or without vomiting.
• Increased urination.
• Fatigue.

Follow these simple tips for how to get pregnant:

1. Have sex regularly. The highest pregnancy rates occur in couples who have sex every day or every other day.
2. Have sex near the time of ovulation.
3. Maintain a normal weight.
