What is the meaning of Isodiametric in biology?
having equal diameters or axes. (of a spore or cell) having nearly equal diameters throughout.
What is the meaning of Isodiametric in Urdu?

What cells are Isodiametric?
Parenchyma cells are usually isodiametric or polyhedral. The word is also means having nearly equal diameters throughout.
What is Isodiametric in parenchyma?
Parenchyma cells can be Isodiametric (equal size in all directions) to elongate in shape. They have thin cell walls which contain a lot of hydrophilic pectins which have a characteristic staining reaction. They usually have well developed Plastids like Chloroplasts or Amyloplasts.
Are parenchyma cells Isodiametric?
Parenchyma is made up of simple, thin-walled, closely packed isodiametric cells, with little intercellular spaces between them. They are living cells and are the most abundant in plants.
Which of the following tissue is Isodiametric?
What is the protection tissue of plant?
The protective tissues in plants consist of epidermis and cork (phellem). > Epidermis: It is the outer covering of cells in plants. It carries out protective function (protecting plants from some unfavorable conditions).
What are Isodiametric with Lignified walls?
Sclerenchyma cells have thick lignified secondary walls and often die when mature. Sclerenchyma provides the main structural support to a plant. So, the correct answer is ‘Parenchyma and sclerenchyma.’
Are Meristematic tissues Isodiametric?
Meristematic Cells are Spherical (Isodiametric) and densely cytoplasmic. They have a relatively large Nucleus, few Vacuoles and thin Cell Walls. Consequently, they readily absorb biological stains and appear as dense areas in the apices of Roots and Shoots.
Why epidermis is called protective tissue?
Explanation: The epidermis is considered a protective tissue because its prime purpose is to form a physical barrier between the outside and inside of the body. On the top stratum (layer) of the epidermis, the cells are dead, and so have no physiological function besides to form a barricade against the outside.
What is Cutin and lignin?
Lignin is one of the chemically complex stuff generally found in different plants that bong its cellulose fibers. Cutin is the best waxy substance present on plant surfaces which tends for making the surface completely waterproof. It also protects leaves from disease and dehydration.
What does isodiametric mean in chemistry?
Isodiametric(adj) developed alike in the directions of the several lateral axes; — said of crystals of both the tetragonal and hexagonal systems. Isodiametric(adj) having the several diameters nearly equal; — said of the cells of ordinary parenchyma.
What do you mean by diameters?
(Mathematics) having diameters of the same length 2. (Chemistry) (of a crystal) having three equal axes 3.
What is the difference between callus and isodiametric epidermis?
tepicensis, in all these species the cells of the epidermis are more isodiametric, larger and homogeneous in shape and size, and of course they are inflated. The callus was formed by isodiametric cells organized in compact form and originating by the division of spongy and palisade parenquima.
