Flowers can be used in making perfumes and beauty products. Tape daily helps us to understand what the main function of flowers except looking beautiful. Pollination. Flowering plants fertilize by pollination. They take pollen from the male part of one flower and transfer it to another part of the female flower Function of Flower. The bright and beautiful part of the plant which you see is the flower. They play a role in making food. A flower has female as well as male parts. Both of these work collectively to fertilize the plant so it can produce seeds. A flower consists of four basic parts, which are petals, sepals, stamens, and pistil Figure 2. The corn plant has both staminate (male) and carpellate (female) flowers. Staminate flowers, which are clustered in the tassel at the tip of the stem, produce pollen grains. Carpellate flower are clustered in the immature ears. Each strand of silk is a stigma. The corn kernels are seeds that develop on the ear after fertilization
. The anther is where the pollen is produced, and each anther contains many grains of pollen that each have the male reproductive cells present in them The main function of flower is to produce fruits and seeds . The main parts of flower are: sepals, petals, stamen and pistil . (1) The green, leaf like parts in the outermost circle of a flower are called sepals. The sepals protect the flower when it is in the form of a bud in the initial stage .sepals may either be separate from one another or.
One by one, explain the function of each plant part. Tell your class that roots hold the plant into the soil. They take in water and minerals to help the plant stay alive. Define the stem as the part that carries water from the roots to the other parts of the plant. Explain that the flower helps the plant reproduce, making seeds that will grow. PART 2. REPRODUCTIVE PART OF A FLOWER MALE PART OF A FLOWER - STAMEN - Stamen is the male reproductive part of a flower, also known as the Androecium. FUNCTION OF THE STAMEN - The main function of the Stamen is to produce pollen and make it available for pollinators such as butterflies, birds, insects, bees etc. to allow reproduction.. 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. Som..

The parts and functions of a flower are much more detailed than they might appear at first glance. If you look at a flower from the top, you will be able to distinguish between four whorls, or circular sections that share a common center. The outer whorl is called the calyx, and consists of the sepals In many flowers, it is the job of the petals to attract insects, so that pollen can be transferred to other flowers. This process is called pollination. The pollen then joins together with, or fertilizes, the ovules, and produces new seeds. The world's biggest flower headis produced by the South American puya. It reaches heights of about 33ft. THE ROOT SYSTEM - It is located below the ground, responsible for absorbing water and minerals from the soil as well as give firmness to the whole plant/tree. The root system includes organs such as the roots, tubers, and rhizomes THE SHOOT SYSTEM - It is located above the ground, helps plants make their food by the process of photosynthesis
Anatomically the flower is a determinate stem with crowded appendages with internodes much shortened or obliterated. The appendages are of leaf rank but differ from those of the vegetative stem, in function and shape.

Flowers. Flowers are the most attractive part of a plant. Each flower types have a different physical structure, colour and scent from those of other flower type plants. Petals and the flowers smell attract insects and bees to pollinate the flower. Sweet smelling flowers petals are used for making perfumes Question 2. What are the functions of flower? Answer: A flower is the seat or organ of sexual reproduction and results in the formation of fruits and seeds. Seeds on germination give rise to new plants. A flower thus, results in multiplication of plants. It is the source of food for many insects The enchanting flowers usually bloom in the mid-summer. It's pretty significant to determine the medium to grow the Verbena. It requires soil which is mostly well-drained and partial shade. To maintain the regular humidity, watering the plant twice a day is definitely great. Unfortunately, it's prone to powdery mildew and slug attack. 2 Root, Stem and Leaf, Getting to know Plants, Class 6, That part of the plant which is below the ground (in the soil), is called root.The part of a plant which rises vertically up from the ground is called stem.The leaf is a thin, broad, flat and green part of a plant which is attached to the stem or branch

The reproductive parts of a flower are actually the most important parts of a flower. This is because a flower's main function is to reproduce so that the plant can pass on its genes. A flower usually reproduces by creating seeds that are then dispersed and eventually become new plants The stamen and pistil are the essential parts of a flower and are involved in seed production. If a flower contains both functional stamens and pistils, it is called a perfect flower, even if it does not contain petals and sepals.If either stamens or pistils are lacking, the flower is called imperfect. Pistillate (female) flowers possess a functional pistil or pistils but lack stamens (Figure 20) Free Question Bank for 3rd Class Science Parts of Plants Plant Life. Customer Care : 6267349244.
