What is zygote how it is formed explain with diagram?
A zygote is the cell formed when two gametes fuse during fertilization. The DNA material from the two cells is combined in the resulting zygote. In single-celled organisms, the zygote becomes a fully functioning organism, and can divide through mitosis to produce offspring. …
What is meant by zygote?
Zygote, fertilized egg cell that results from the union of a female gamete (egg, or ovum) with a male gamete (sperm). In the embryonic development of humans and other animals, the zygote stage is brief and is followed by cleavage, when the single cell becomes subdivided into smaller cells.
What is a zygote Class 8?
A zygote is the first diploid cell that is formed by the fusion of male and female gametes resulting in the formation of an embryo. The genome of the zygote is the combination of DNA in each gamete and contains all the genetic information required to form an individual. …
What is a zygote Class 7?
A zygote is an egg which is formed after fertilization of male gamete and female gamete.
What is embryo for Class 7th?
An embryo is an early stage of development of a multicellular diploid eukaryotic organism. In general, in organisms that reproduce sexually, anembryo develops from a zygote, the single cell resulting from the fertilization of the female egg cell by the male sperm cell. The result of this process is an embryo.
What are decomposers Class 7?
Answer: Decomposers are organisms that act on dead plants and animals, and convert them into a dark colored substance called humus. Bacteria and some fungi act as decomposers. They play a key role in releasing the nutrients present in dead plants and animals into the soil.
What are two kinds of decomposers?
Decomposers break down what’s left of dead matter or organism waste. Douglas_Eisenberg. Bacteria and fungi are the two types of decomposers.
What are called decomposers?
A decomposer is an organism that decomposes, or breaks down, organic material such as the remains of dead organisms. Decomposers include bacteria and fungi. These organisms carry out the process of decomposition, which all living organisms undergo after death.
Why is bacteria a decomposer?
Decomposers (fungi, bacteria, invertebrates such as worms and insects) have the ability to break down dead organisms into smaller particles and create new compounds. We use decomposers to restore the natural nutrient cycle through controlled composting.
Can bacteria be a decomposer?
Most decomposers are microscopic organisms, including protozoa and bacteria. Other decomposers are big enough to see without a microscope. They include fungi along with invertebrate organisms sometimes called detritivores, which include earthworms, termites, and millipedes.
Is bread a decomposer?
The mold that grows on bread would be a decomposer. The reason why it would be a decomposer is because when the bread starts molding, it decomposes to get energy from it. The mold in the bread would be a fungi growing on the bread, and fungi decomposes.
