Which cell can reproduce sexually and asexually?

Which cell can reproduce sexually and asexually?

Explanation: Prokaryotic cells can reproduce either sexually and asexually. In a bacterial cell, sexual reproduction occurs via three different methods: conjugation, transformation, and transduction.

Which kingdom reproduces both sexually and asexually?

Kingdom Fungi
Kingdom Fungi includes organisms such as mushrooms and molds. Most fungi are multicellular and can reproduce sexually or asexually.

Do animals reproduce sexually asexually or both?

Some animals produce offspring through asexual reproduction while other animals produce offspring through sexual reproduction. Both methods have advantages and disadvantages. Asexual reproduction produces offspring that are genetically identical to the parent because the offspring are all clones of the original parent.

What are 2 types of cell reproduction?

We will be discussing two different types of cell reproduction–mitosis and meiosis. These processes are responsible for creating two different types of cells. Mitosis is a process that creates a nearly exact copy of the original cell.

Are hydras asexual?

When food is plentiful, many Hydra reproduce asexually by budding. The buds form from the body wall, grow into miniature adults and break away when mature. When a hydra is well fed, a new bud can form every two days.

Is Protista asexual or sexually?

Protists reproduce asexually by budding and binary fission. Binary fission is a form of multiple fission and is also considered the most typical form of reproduction in the protista kingdom. Budding occurs when asexual reproduction produces a bud — a daughter nucleus — which then develops into its own structure.

Are there 5 or 6 kingdoms?

Until recently the system devised by Robert Whittaker in 1968 was widely adopted. Whittaker’s classification scheme recognizes five kingdoms: Monera, Protista, Fungi, Plantae, and Animalia.

Can a human reproduce asexually?

While parthenogenesis makes it possible for females to reproduce without males, males have no way to reproduce without females. Therefore, once sex has evolved and males are present in the population, those males will try to mate, even with reluctant females that might have done better to clone themselves.

Are sea urchins asexual?

Instead, they spawn, meaning that they release their eggs and sperm into the water, reproducing sexually. In particular, Sea Urchins leave reproduction to chance. They do not select a mate, but rather release their gametes and leave it to chance that they will mix and get fertilized.

Which are two main types of reproduction in living organisms?

There are two types of reproduction: asexual and sexual reproduction. Though asexual reproduction is faster and more energy efficient, sexual reproduction better promotes genetic diversity through new combinations of alleles during meiosis and fertilization.

Can a cell reproduce?

All living cells and organisms reproduce, producing offspring like themselves, and pass on the hereditary information contained in their DNA molecules. The processes of reproduction, while varied and complex, depends upon the ability of individual cells to replicate.

Can we see hydra with naked eyes?

Hydra are truly fascinating small aquatic animals. Most hydra are tiny, reaching a maximum of only about 30 mm long when fully extended. They are barely visible to the naked eye and a hand lens or microscope are needed to be able to see them properly.

How do hydras die?

A biologically immortal living being can still die from means other than senescence, such as through injury, poison, disease, lack of available resources, or changes to environment.

How do protists benefit humans?

Plant-like protists produce almost one-half of the oxygen on the planet through photosynthesis. Other protists decompose and recycle nutrients that humans need to live. For example, medicines made from protists are used in treatment of high blood pressure, digestion problems, ulcers, and arthritis.

How do protists reproduce sexually and asexually?

Protists can reproduce asexually through binary fission, one nucleus divides; multiple fission, many nuclei divide; and budding. Protists reproduce sexually through the processes of conjugation and alternation of generations. Conjugation is a temporary union of protists in which they exchange genetic material.

Who is the father of five kingdom classification?

Whittaker proposed an elaborate five kingdom classification – Monera, Protista, Fungi, Plantae and Animalia.

Why do we classify the six kingdoms?

Woese found that the six kingdoms naturally cluster into three main categories, based on the sequence of 16s ribosomal RNA genes. He called these categories as domains of life. These domains are Bacteria, Archaea, and Eukarya. He also believed that these domains have originated from common ancestors called Progenote.

Why offspring are not exact replicas of their parents?

In sexual reproduction one full set of the genes come from each parent. Living things produce offspring of the same species, but in many cases offspring are not identical with each other or with their parents. These provide the information that is needed to make more cells in growth and reproduction.

Can a woman self impregnate?

Self-fertilization may also occur in human. A scenario is presented here for a woman to have a son without a father: she is a chimera of 46,XX/46,XY type resulting from the fusion of two zygotes of different sex types and she develops both ovary and testis in her body.

How do sea urchins poop?

Urchin mouths are on the bottom of their body; during digestion, food travels up the intestine to the anus, which sits on the top of the body. Deep-sea urchin in the process of defecating. Urchin mouths are on the bottom of their body, while the anus is on the top of the body.
