Flower Terms. An inflorescence grows from a main stem, also called a peduncle. The term “stem axis” is sometimes used instead of peduncle. A pedicel is short flower stalk that grows from a peduncle.
In respect to this, what does the receptacle?
Botany. the modified or expanded portion of the stem or axis that bears the organs of a single flower or the florets of a flower head. Electricity. a contact device installed at an outlet for the connection of a portable lamp, appliance, or other electric device by means of a plug and flexible cord.
What is the receptacle of a plant?
The receptacle is the axis (stem) to which the floral organs are attached. Floral organs are attached either in a low continuous spiral, as is common among primitive angiosperms, or in alternating successive whorls, as is found among most angiosperms.
What is the difference between a receptacle and an outlet?
Another name for a receptacle is an electrical outlet. Electrical outlets or receptacles are often called plugs or plug-ins, but a plug is the proper term for the male cord end (that plugs into an outlet or a receptacle). Receptacle Outlet. An outlet where one or more receptacles are installed.
What is the main function of the fruit?
As a plant organ and container of seed or seeds, the two primary functions of fruits are protection and seed dispersal. 1. Fruits protect the seeds. The fruit serves as a physical barrier between the seed or seeds and the external environment during seed development.
What is a flower and its functions?
Flowers are an important part of the reproductive system of plants. Each flower produces pollen, which is released through the anther part of the stamen. Some flowers produce pollen that is carried by the wind to other flowers so that fertilization takes place. Many flowers require a pollinator to carry the pollen.
What is a Perigynous flower?
perigynous. adjective. Having sepals, petals, and stamens around the edge of a cuplike receptacle containing the ovary, as in flowers of the rose or cherry. Of or being perigynous flower parts: perigynous stamens.
What is floral formula?
Floral formula is a means to represent the structure of a flower using numbers, letters and various symbols, presenting substantial information about the flower in a compact form. It can represent particular species, or can be generalized to characterize higher taxa, usually giving ranges of organ numbers.
What is the function of a leaf?
Its main functions are photosynthesis and gas exchange. A leaf is often flat, so it absorbs the most light, and thin, so that the sunlight can get to the chloroplasts in the cells. Most leaves have stomata, which open and close. They regulate carbon dioxide, oxygen, and water vapour exchange with the atmosphere.
What is the pedicel of a flower?
A pedicel is a stem that attaches a single flower to the inflorescence. In the absence of a pedicel, the flowers are described as sessile. The stem or branch from the main stem of the inflorescence that holds a group of pedicels is called a peduncle.
What do flowers produce?
Flowers have male parts called stamens that produce a sticky powder called pollen. Flowers also have a female part called the pistil. The top of the pistil is called the stigma, and is often sticky. Seeds are made at the base of the pistil, in the ovule.
What is the function of the stamen in a flower?
The main function of the stamen is to produce the pollen grains, which house male gametes, or sex cells, necessary for reproduction. The anther is located within the stamen where these gametes are created. Pollen grains vary in size, shape, and surface structures based on the type of flower that produces them.
What are the parts of the flower and their functions?
Parts of the flower and their functions
petals. brightly coloured, attract insects.
stamen. male part of the flower, made up of anther and filament.
anther. produces male gametes – pollen.
filament. supports anther to make it accessible to insects.
ovary. contains ovules.
ovule. In seed plants, the female reproductive part that produces the gamete – egg.
Why do flowers come in different colors?
Flower colors of red, pink, blue and purple come mainly from the pigments called anthocyanins, which are in the class of chemicals called flavanoids (what gives plants their color). Other pigments are carotenoids, found in tomatoes and carrots, that provide yellow, red and orange in the plastids.
What is the function of the receptacle in a flower?
flower anatomy. The receptacle is the axis (stem) to which the floral organs are attached. Floral organs are attached either in a low continuous spiral, as is common among primitive angiosperms, or in alternating successive whorls, as is found among most angiosperms.
What is the function of the stem in the plant?
Stems have four main functions which are: Support for and the elevation of leaves, flowers and fruits. The stems keep the leaves in the light and provide a place for the plant to keep its flowers and fruits. Transport of fluids between the roots and the shoots in the xylem and phloem.
What is the purpose of the pedicel in a flower?
An inflorescence grows from a main stem, also called a peduncle. The term “stem axis” is sometimes used instead of peduncle. A pedicel is short flower stalk that grows from a peduncle. In researching plants, you might see the terms racemes, umbrels, cymes and corymbs used to describe flowers.
What is the function of the fruit of the plant?
It usually contains seeds, which have developed from the enclosed ovule after fertilization, although development without fertilization, called parthenocarpy, is known, for example, in bananas. The principal botanical purpose of the fruit is the protection and dissemination of the seed.
What is the function of a petal in a flower?
Petals are modified leaves that surround the reproductive parts of flowers. They are often brightly colored or unusually shaped to attract pollinators. Together, all of the petals of a flower are called a corolla.
What is the function of the stigma of a flower?
The function of the stigma in a flower is as a pollen receptor. The stigma is a sticky tip on the top of a carpel.The stigma is contained inside of the pistil, which also contains the ovary, style and carpel. The carpel and its other parts can often be referred to as the gynoecium.
What is the function of the fruit of a plant?
The function of a flower is to produce the reproductive cells of the plant (eggs and pollen) and then produce seeds, the dormant young plant of the next generation. The seeds of flowering plants are surrounded by a tissue called the fruit, which may be fleshy or dry.
What is the function of the seed?
The endosperm is the food storage area of the seed. The purpose of the seed coat is to protect the seed from physical, temperature-related, or water damage. The seed coat also ensures that the plant seed remain in a state of dormancy until conditions are right for the plant embryo to germinate, or sprout.
What are sepals of a flower?
Sepal: The outer parts of the flower (often green and leaf-like) that enclose a developing bud. Petal: The parts of a flower that are often conspicuously colored. Stamen: The pollen producing part of a flower, usually with a slender filament supporting the anther.
