Which of the below statements is false?a)Male and female gametes devel...
False statement: Male and female gametes develop in sexual organs called gametophytes.

Explanation:

Introduction:
In plants, the process of sexual reproduction involves the fusion of male and female gametes. This process occurs in two distinct stages: gametophyte and sporophyte.

1. Gametophyte stage:
- The gametophyte stage is the haploid stage of the plant life cycle where male and female gametes are produced.
- This stage begins with the germination of spores, which are haploid structures.
- These spores develop into multicellular structures called gametophytes.
- In the gametophyte, male gametes (sperm) and female gametes (egg) are produced.

2. Fertilization:
- Male gametes are delivered to female gametes for fertilization.
- In plants, this is often achieved through water-dependent mechanisms, such as the transfer of pollen grains to the female reproductive structures.

3. Zygotic stage:
- Once fertilization occurs, the male and female gametes fuse to form a zygote.
- The zygote is a diploid structure that develops into an embryo.

4. Sporophyte stage:
- The embryo continues to grow and develop into a multicellular structure known as the sporophyte.
- The sporophyte is the diploid stage of the plant life cycle and is capable of producing spores.

Conclusion:
The false statement is option A: Male and female gametes develop in sexual organs called gametophytes. In reality, gametophytes are the structures where male and female gametes are produced, and the fusion of these gametes occurs during fertilization to form an embryo. The embryo then develops into a sporophyte, which is responsible for producing spores.

Which of the below statements is false?a)Male and female gametes devel...
Gametes are created in sex organs known as gametangia. Gametophyte is the life cycle of sexual reproduction. It takes water for the male gametes to reach the female gametes. In order to create a zygotic structure, which eventually becomes an embryo, male and female gametes must fuse further. A haploid structure known as a sporophyte that bears spores grows from this embryo throughout time.

In pteridophytes the sporophyte produces spores through meiosis. The spores are produced by the sporangia in the spore mother cells. These spores germinate to give rise to gametophytes. The gametophytes bear male and female sex organs. Water is required for transfer of antherozoids - the male gametes released from the male sex organ to the mouth of female sex organ. Fusion of male gamete with the egg result in the formation of zygote. Zygote thereafter produces a multicellular well-differentiated sporophyte. In majority of the pteridophytes all the spores are of similar kinds. However, some genera also produce two kinds of spores, macro (larg e) and micro (small) spores. The megaspores and microspores germinate and give rise to female and male gametophytes, respectively. In these plants, the female gametophytes are retained on the parent sporophytes for variable periods. The development of the zygotes develop into young embryos within the female gametophytes. This event is a precursor to the seed habit considered an important step in evolution. Direction : In the above questions the Assertions (
