Which part of the flower produces sperm cells?
The anther produces pollen grains, which contain the sperm cells necessary for fertilization.
What are the agents of cross pollination in plants?
Cross pollination is often facilitated by external agents such as wind, insects, and animals.
What is the name of the female reproductive part of a flower?
The carpel is the female reproductive part of a flower and consists of the stigma, style, and ovary.
Sexual reproduction in plants involves:
Sexual reproduction in plants involves the fusion of sperm and egg cells during fertilization.
Which type of reproduction does not involve gametes?
Asexual reproduction does not involve the fusion of gametes and typically involves only one parent.
What is the first step of sexual reproduction in plants?
Pollination is the first step of sexual reproduction in plants, where pollen is transferred to the stigma.
What is pollination?
Pollination is the process of transferring pollen from the anther to the stigma of a flower.
What happens after pollination in sexual reproduction?
After pollination, fertilization occurs where the sperm cell fuses with the egg cell.
Which parts of the flower are involved in sexual reproduction?
The anther and ovary are key parts involved in the sexual reproduction of flowers.
Where are pollen grains produced in a flower?
Pollen grains are produced in the anther, which is part of the male reproductive organ of a flower.
What do ovary cells produce in flowers?
The ovary contains ovules, which produce the egg cells necessary for fertilization.
How do sperm cells reach the ovule in a flower?
Sperm cells reach the ovule through the pollen tube, which grows from the pollen grain after it lands on the stigma.
What is formed after fertilization of the ovule?
After fertilization, the ovule develops into a seed.
What does the fertilized ovary become?
After fertilization, the ovary typically develops into a fruit.
What is fertilization in plants?
Fertilization in plants is the fusion of sperm and egg cells, leading to the formation of a zygote.
Which type of pollination involves pollen from the same plant?
Self pollination involves the transfer of pollen from the anther to the stigma of the same flower or another flower on the same plant.
In cross pollination, pollen is transferred to the stigma of a flower on:
Cross pollination involves the transfer of pollen to the stigma of a flower on a different plant.
Which of the following is not an agent of cross pollination?
Sunlight is not an agent of cross pollination; it is essential for photosynthesis.
Which structure forms after pollen lands on the stigma and matures?
After pollen lands on the stigma, it germinates and forms a pollen tube that grows down to the ovary.
What is the function of the pollen tube?
The pollen tube carries the sperm cells from the pollen grain to the ovule for fertilization.
What does the fusion of sperm and egg cell lead to?
The fusion of sperm and egg cells during fertilization leads to the formation of a zygote.
Which structure contains the egg cell in a flower?
The ovary contains the ovules, which house the egg cells.
What is the female reproductive part of a flower?
The pistil is the female reproductive part of a flower, consisting of the stigma, style, and ovary.
Which part connects the ovary to the stigma?
The style is the structure that connects the ovary to the stigma in a flower.
Which part of the flower is sticky to trap pollen grains?
The stigma is sticky to trap pollen grains during the process of pollination.
Brightly coloured petals help in:
Brightly coloured petals help in attracting pollinators to the flower.
Which pollination involves transfer of pollen to the same flower?
Self pollination involves the transfer of pollen to the same flower.
Cross pollination occurs when:
Cross pollination occurs when pollen is transferred from one flower to another.
Which of these is NOT a reproductive part of a flower?
Petals are not directly involved in the reproductive process of a flower.
Which part of the flower contains the egg cell?
The ovary contains the egg cell in a flower.
Which part supports the entire flower on the stem?
The pedicel supports the entire flower on the stem.
The stamen consists of:
The stamen consists of the anther and filament.
What happens when the anther bursts?
When the anther bursts, it releases mature pollen grains.
Which type of pollination involves only one plant?
Self pollination involves only one plant.
Which type of pollination results in new plant varieties?
Cross pollination results in new plant varieties due to genetic diversity.
Which of the following is not a feature of cross pollination?
Cross pollination involves two flowers and does not occur in only one plant.
Which type of pollination involves two or more plants of the same kind?
Cross pollination involves two or more plants of the same kind.
Which plant is mostly pollinated by water?
Coconut is mostly pollinated by water.
Which part of the plant performs sexual reproduction?
The flower is the part of the plant that performs sexual reproduction.
How many types of reproduction are found in plants?
There are two types of reproduction found in plants: sexual and asexual.
Which reproductive method uses sex cells?
Sexual reproduction uses sex cells (gametes).
In sexual reproduction, which cells fuse together?
In sexual reproduction, male and female gametes fuse together.
What are male sex cells in plants called?
Male sex cells in plants are called pollen grains.
What structure in a flower produces pollen grains?
The anther is the structure in a flower that produces pollen grains.
Where is the egg cell located in a flower?
The egg cell is located in the ovule of a flower.
Which structure helps pollen grains reach the ovule?
The pollen tube helps pollen grains reach the ovule.
What is fertilization in plants?
Fertilization in plants is the fusion of male and female sex cells.
What is the result of fertilization?
The result of fertilization is a zygote.
What does the zygote develop into?
The zygote develops into an embryo.
What part of the flower turns into a fruit after fertilization?
The ovary turns into a fruit after fertilization.
What happens to the ovule after fertilization?
After fertilization, the ovule becomes a seed.
Which of the following is NOT a part of the flower?
Root hair is not a part of the flower.
Which of the following is true about asexual reproduction?
Asexual reproduction involves one parent only.
Which reproduction results in genetically identical offspring?
Asexual reproduction results in genetically identical offspring.
Which process leads to rapid production of many offspring?
Asexual reproduction leads to the rapid production of many offspring.
What structure protects the embryo inside the seed?
The seed coat protects the embryo inside the seed.
What does the ovary wall develop into after fertilization?
The ovary wall develops into the fruit wall after fertilization.
What is formed from the fusion of sperm and egg in plants?
The fusion of sperm and egg in plants results in the formation of a zygote.
