Quick Answer: How does the male gamete reach the female gamete and form the zygote?

How does the male gamete reach the female gamete?

A pollen tube grows through the tissues of the flower until it reaches an ovule inside the ovary . The nucleus of the pollen grain (the male gamete ) then passes along the pollen tube and joins with the nucleus of the ovule (the female gamete).

How does the male gamete reach the egg?

Pollen grains bear the male gamate. When the pollen grains reach the stigma of a pistal, it germinates to give out a pollen tube. … The pollen tube grows to reach the ovary and the ovule. When the pollen tube reaches the ovule, it pushes the male gametes into the egg cell.

How male gamete is formed?

Complete answer: Male gametes are formed by Generative cells. A typical anther contains four microsporangia. The microsporangia form sacs or pockets within the anther (anther sacs or pollen sacs) . … The generative cell divides mitotically to form the two male gametes.

What is the process of male and female gamete fusion?

Answer: The term used to describe the male and female gametes fusion is fertilization. Fertilization can be described as the fusion of the male gametes (pollen) with the female gametes (ovum) to form a diploid zygote. It is a process that occurs after the pollination of the carpel.

What happens to flower after fertilization?

After fertilization the flower withers. The sepals and the petals dry up, the ovary converts into fruit, the ovule forms the seed and the zygote forms the embryo which is enclosed in the seed.

Where the male gametes are present?

Male gametes are called sperms. They are formed in testes that are located in a muscular sac called scrotum that hang outside a male body.

Is a sperm a cell?

In the human reproductive process, two kinds of sex cells, or gametes (GAH-meetz), are involved. The male gamete, or sperm, and the female gamete, the egg or ovum, meet in the female’s reproductive system.

What is it called when a sperm cell joins with an egg?

The male gamete, or sperm, and the female gamete, the egg or ovum, meet in the female’s reproductive system. When sperm fertilizes (meets) an egg, this fertilized egg is called a zygote (ZYE-goat). The zygote goes through a process of becoming an embryo and developing into a fetus.

Why do men produce more gametes?

The sex that produces small and numerous gametes (that is, the male) will more-often-than-not have higher potential reproductive rates. The primary consequence of anisogamy is therefore that reproductive competition (for mates – i.e. sexual selection) will generally be greater in males.

What is male gamete called?

Gametes are an organism’s reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Each sperm cell, or spermatozoon, is small and motile. …

What is male gamete called in Heterogametic condition?

Heterogametic means there is a difference in the gametes formed by a particular organism. As a bio student, you must know that females, have only one type of gamete(egg) which is XX. But in males, the gametes (sperms) can be XX or XY. … Whereas, the females are known as homogametic.

What is the name of female sperm?

In the human reproductive process, two kinds of sex cells, or gametes (GAH-meetz), are involved. The male gamete, or sperm, and the female gamete, the egg or ovum, meet in the female’s reproductive system.
