Parts of a flower
| Structure | Function |
|---|---|
| Stamens | The male parts of the flower (each consists of an anther held up on a filament) |
| Anthers | Produce male sex cells (pollen grains) |
| Stigma | The top of the female part of the flower which collects pollen grains |
| Ovary | Produces the female sex cells (contained in the ovules) |

What are the two functions of stigma?
Ans: In a flower, this landing zone and entrance is the stigma. It plays a pivotal role in reproduction. Most stigmas are adapted to trap pollen with hairs, flaps and other surfaces to increase their efficiency. Most stigmas are covered with a waxy, sticky substance.
What is the function of stigma Brainly?
the function of stigma in a flower is the pollen receptor . the stigma is a sticky tip on top of carpel. the stigma is contained inside of the pistil, which also contains the ovary, style and carpel . these tubes become part of the stigma and helps it to receive the Pollen .
What is the function of stigma and style?
The stigma is at the top of the style and is a sticky platform where pollen is deposited. The ovary is located at the bottom of the style and houses the plant's ovules, which contain the egg cells and supporting cells necessary for reproduction.
What is the functional activity of stigma?
Function of a Stigma
Pollen is often transferred by wind or by animals, such as butterflies and bees. In order for the pollen to reach the female gametophyte inside the pistil, it must have a place to land and enter. In a flower, this landing zone and entrance is the stigma. It plays a pivotal role in reproduction.
What is the main function of parenchyma?
The main function of parenchyma is to store food and provide turgidity to organ where it is found.
What is the function of the stigma style and ovary?
The stigma is the sticky knob at the top of the pistil. It is attached to the long, tubelike structure called the style. The style leads to the ovary that contains the female egg cells called ovules.
What is the function of stigma Class 10?
Stigma is the topmost part of carpels in the gynoecium of a flower. In all flowering plants, stigma functions as a receptive tip, which collects pollen grains.
What is function of stigma in reproduction?
The main function of stigma in reproduction is to receive the matured pollen grain by the process of pollination either by biotic or abiotic factors. Stigma, style, and ovary together constitute the carpel, which is the unit of gynoecium.
What is the function of stigma in fertilization?
Stigma is the receptacle on which the pollen lands and germinates, produces a pollen tube that grows through the style towards the ovule/egg to effect fertilisation and seed set. Transfer of pollen from one flower to another is achieved by agents like wind, water or animals.
What is the function of a stigma of a flower?
plant reproduction
The stigma is a specially adapted portion of the pistil modified for the reception of pollen. It may be feathery and branched or elongated, as in such wind-pollinated flowers as those of the grasses, or it may be compact and have a sticky surface.
What is the main function of style?
Style is the tube-like structure that supports the stigma. A major function of style is to assist the process of fertilization – by allowing pollen tubes to travel to deliver sperm cells to the egg.
What is the function of ovule?
Ovule Definition. The ovule is part of the makeup of the female reproductive organ in seed plants. It's the place where female reproductive cells are made and contained, and it is what eventually develops into a seed after fertilization, only for the seed to then ripen and produce a complete adult plant.
What is the function of pollen tube?
Introduction. The pollen tube (PT) is a unique and specialized structure in plants. Its sole purpose is to deliver sperm cells to the female gametophyte for double fertilization. Essentially, it is a thread–like structure spanning from the pollen shell toward the tip.
What are the functions of filament?
The filament is a thin tubular part of the stamen, which extends and supports the pollen sac at the top. The function of filaments in plants is to carry nutrients to the anther, where the pollen develops.
What are the functions of parenchyma tissue class 9?
Parenchyma mainly works as packing material in plant parts. The main function of parenchyma is to provide support and to store food.
What is the function of parenchyma Class 7?
The main function of parenchyma is to store and assimilate food. Hence, they are referred to as food storage tissues.
What is the main function of the parenchyma cells of the root cortex?
Parenchyma cells are the most common plant cells (Figure 2). They are found in the stem, the root, the inside of the leaf, and the pulp of the fruit. Parenchyma cells are responsible for metabolic functions, such as photosynthesis, and they help repair and heal wounds. Some parenchyma cells also store starch.
