A. Fertilisation is
the process of fusion of male and female gametes
. … Usually the pollen tube
What is fertilisation in plants?
Fertilization in flowering plants happens through a process called pollination. …
Fertilization occurs when one of the sperm cells fuses with the egg inside of an ovule
. After fertilization occurs, each ovule develops into a seed. • Each seed contains a tiny, undeveloped plant called an embryo.
What is fertilization 10th class?
Fertilization can be defined as
the fusion of the male gametes (pollen) with the female gametes (ovum) to form a diploid zygote
. It is a physicochemical process which occurs after the pollination of the carpel.
What is fertilization Class 10 short answer?
Fertilization is the
process by which male and female gametes are fused together
, initiating the development of a new organism.
What is the site of fertilisation in plants Class 10?
Fertilization in plants: In plants, pollination is followed by fertilization. Once the pollen grains are deposited on the stigma, it forms the pollen tube. The pollen tube grow through the ovules and reach
the ovary
where the egg cell is located.
What is Syngamy class 10th?
The
fusion of male and female gametes during the fertilization
is known as syngamy. The fusion of the sperm cell with the two polar nuclei during the double fertilization is known as triple fusion. Development. During syngamy, zygote is produced which forms the embryo.
What is germination class 10th?
Complete Answer:
Germination refers to
the method by which an associated organism grows from a seed or a reproductive structure
. … This method is initiated by specific enzymes that become activated once the seed is exposed to water. The roots grow downwardly, and also the shoot grows upwards towards the soil surface.
What are the 4 steps of fertilization?
The stages of fertilization can be divided into four processes: 1) sperm preparation, 2) sperm-egg recognition and binding, 3) sperm-egg fusion and 4) fusion of sperm and egg pronuclei and activation of the zygote.
What are the 5 stages of Fertilisation?
- Sperm Capacitation. …
- Sperm-Zona Pellucida Binding. …
- The Acrosome Reaction. …
- Penetration of the Zona Pellucida. …
- Sperm-Oocyte Binding. …
- Egg Activation and the Cortical Reaction. …
- The Zona Reaction. …
- Post-fertilization Events.
What are the types of Fertilisation?
In animals, there are two types of fertilization,
internal and external
. Internal fertilization happens in the female body. External fertilization happens outside of the body. Mammals, birds, and reptiles use internal fertilization.
What are the 6 steps of fertilization?
- Sperm Capacitation.
- Sperm-Zona Pellucida Binding.
- The Acrosome Reaction.
- Penetration of the Zona Pellucida.
- Sperm-Oocyte Binding.
- Egg Activation and the Cortical Reaction.
- The Zona Reaction.
- Post-fertilization Events.
What is meant by reproduction?
1 : the act or process of reproducing specifically :
the process by which plants and animals give rise to offspring
and which fundamentally consists of the segregation of a portion of the parental body by a sexual or an asexual process and its subsequent growth and differentiation into a new individual.
What happens when egg is fertilized Class 10?
If the egg is fertilized by a sperm as it travels down the fallopian tube, then
pregnancy
occurs. The fertilized egg attaches to the lining of the uterus. The placenta then develops. … If the egg does not become fertilized, the lining of the uterus (endometrium) is shed during menstruation.
What will happen after fertilization?
Once fertilization takes place, this newly fertilized cell is called a zygote. From here, the zygote
will move down the fallopian tube and into the uterus
. The zygote then burrows into the uterus lining. This is called implantation.
What are the two types of fertilization in plants?
The three main types of plant fertilization –
porogamy, chalazogamy, and mesogamy
– are distinguished by how the pollen tube enters the ovule. Of these three, porogamy is most common.
What is Fertilisation short answer?
Fertilization:
The process of combining the male gamete, or sperm, with the female gamete, or ovum
. The product of fertilization is a cell called a zygote.
