What is the function of sepals?

The sepal is a defensive organ that encloses and protects the developing reproductive structures. At maturity, the sepal opens when the flower blooms. The outer sepal epidermis (see Fig.

What is sepal and petal?

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.

What is the function of sepals Class 7?

Sepals are small, leaf-shaped, green-coloured and outermost part of the flower. They are the vegetative part of a flower, which functions by protecting the rising buds and by supporting the petals when in bloom. The sepals are considered as the modified leaves.

What is the difference between a flower and a petal?

is that petal is (botany) one of the component parts of the corolla of a flower, when this consists of separate parts, that is it is not fused petals are often brightly colored while flower is a colorful, conspicuous structure associated with angiosperms, frequently scented and attracting various insects, and which may …

Which word is used if sepal and petal Cannot be differentiated?

When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. When the undifferentiated tepals resemble petals, they are referred to as “petaloid”, as in petaloid monocots, orders of monocots with brightly colored tepals.

What is the function of stamen and pistil?

stamen[]:- it is the male reproductive organ of a flower its function is to produce male gametes that help in fertilization. pistil: also known as carpel is the female reproductive organ of a flower. its function is to store ovum.

Is pistil and carpel same?

What is the difference between a carpel and a pistil? Carpels are the basic units of the gynoecium and may be free (distinct) or fused (connate). The term pistil is used in a similar manner to carpel – in some situations the terms are equivalent in meaning but not in others.

What is the function of sepals Class 6?

What is the function of flower in plant?

The primary purpose of the flower is reproduction. Since the flowers are the reproductive organs of the plant, they mediate the joining of the sperm, contained within pollen, to the ovules — contained in the ovary.

What is the difference between petal and tepal?

is that tepal is (botany) one of the component parts of the perianth, the outermost whorls of flower parts, especially when the perianth is not divided into two whorls of unequal appearance while petal is (botany) one of the component parts of the corolla of a flower, when this consists of separate parts, that is it is …

What is the function of the sepals on a flower?

Sepals are modified leaves that form the outer whorl of a flower and are the first part of a flower to form. They develop at the top of the stem and form a tightly closed area, often referred to as a bud. Sepals function to protect the developing flower and keep it from drying out.

Which is the main support tissue of the phloem?

Sclerenchyma The sclerenchyma is the main support tissue of the phloem, which provides stiffness and strength to the plant. The bast fibers, which support the tension strength while allowing flexibility of the phloem, are narrow, elongated cells with walls of thick cellulose, hemicellulose and lignin and a narrow lumen (inner cavity).

Which is part of a plant are xylem and phloem found in?

Xylem is mainly a water conducting tissue and phloem is concerned with the conduction and storage of organic food in plants. Both xylem and phloem are components of vascular bundles in plants. Roots absorb water and it is through xylem water is taken to stem and leaves.

How does water move through the phloem in plants?

Water is drawn passively from the adjacent xylem over the gradient to create a sugar solution and a high turgor pressure within the phloem. The high turgor pressure causes the water and sugars to move through the tubes of the phloem, in to the ‘sink tissues’ (e.g. the roots, growing tips of stems and leaves, flowers and fruits).
