What is Isobilateral?

What is Isohaline in social?

Isohaline is an ‘imaginary line’ on a map that connects all points of the ocean with same salinity. Explanation: Iso means ‘same’ and haline means ‘salinity’. What is Isonephs geography?
: a line on a map connecting points that have the same average percentage of cloudiness.

What is Dorsoventral leaf?

A dorsiventral (Lat. dorsum, the back, venter, the belly) organ is one that has two surfaces differing from each other in appearance and structure, as an ordinary leaf. This term has also been used as a synonym for dorsoventral organs, those that extend from a dorsal to a ventral surface. What is bifacial leaf?

A dicotyledonous leaf is also called dorsiventral or bifacial leaf. For example, mango leaves, banyan leaves and oleander leaves. These leaves are hypostomatic (stomata mostly on the lower epidermis). Mesophyll tissues present in these leaves are differentiated into palisade and spongy.

Frequently Asked Questions(FAQ)

What is Dicot leaf?

dicotyledon, byname dicot, any member of the flowering plants, or angiosperms, that has a pair of leaves, or cotyledons, in the embryo of the seed. … The leaves are net-veined in most, which means the vessels that conduct water and food show a meshlike pattern.

What is isodose?

: of or relating to points or zones in a medium that receive equal doses of radiation.

What is a Isodrosotherm?

Isodrosotherms are lines of equal dew point temperatures. Dew Points tell us how much moisture is near the surface. Isotherms and isodrosotherms are usually shown on weather maps in intervals of 5 or 10 degrees.

What are Isotachs used for?

These are lines of equal wind speed. They are most often contoured in the upper levels of the atmosphere, especially at the jet stream level. They are important for locating the jet stream and jet streaks within a jet stream. This 300 mb image is an example of isotachs.

What is called Isohaline?

What causes a Halocline?

A halocline is also a layer of separation between two water masses by difference in density, but this time it is not caused by temperature. It occurs when two bodies of water come together, one with freshwater and the other with saltwater. Saltier water is denser and sinks leaving fresh water on the surface.

Which of the following is shown by Isohalines?

1. Horizontal distribution of salinity is shown by Isohalines which are imaginary lines connecting the areas of similar salinity. 2. Due to high temperature, areas on the equator have the highest salinity.

What is an Isohyet map?

: a line on a map or chart connecting areas of equal rainfall.

Who used Isodapane?

Alfred Weber Isodapane is a similar term to the geographical term isotherm. It was introduced by Alfred Weber. It means equal transportation cost, used in industrial and economic geography. It is a theoretical tool used to assist in finding the optimal location for industry.

What’s the difference between dorsiventral leaf and Isobilateral leaf?

Anatomy of Flowering Plants, Anatomy of Dicotyledonous and Monocotyledonous… …

Dorsiventral Leaf	Isobilateral Leaf
The number of stomata is more on the abaxial epidermis than the adaxial epidermis.	Almost equal number of stomata is present on the abaxial and adaxial surfaces.

•

What are the 3 types of leaves?

Leaves are classified as either alternate, spiral, opposite, or whorled. Plants that have only one leaf per node have leaves that are said to be either alternate or spiral. Alternate leaves alternate on each side of the stem in a flat plane, and spiral leaves are arranged in a spiral along the stem.

What is dorsiventral symmetry?

Abstract. The higher plant shoots are generally radially symmetrical; leaves produced at the shoot apex are dorsiventral while axillary shoots again show radial symmetry.

Why is it necessary to have veins in the leaf?

In short, plant veins provide structure and support to plant leaves while also transporting water, nutrients, and energy to the rest of the plant. When plants absorb water and nutrients through their roots, they use their vascular system to move the water and nutrients up into the rest of the plant.

What are known as Bulliform cells?

Bulliform cells or motor cells are large, bubble-shaped epidermal cells that occur in groups on the upper surface of the leaves of many monocots. These cells are present on the upper surface of the leaf.

Where parallel venation is found?

Parallel venation is found in monocot plants. Monocots are those flowering plants in which seeds contain only one cotyledon or embryonic leaf. Examples are bamboo, banana, grass, maize and wheat. Additional information: Due to the presence of mid veins, the parallel venation is divided into 2 types.

What are the monocot leaves?

Monocot Leaf Monocot leaves are slender and elongated with parallel veins. Compared to other forms of veins, in parallel venation, the veins are small in size with even smaller veins connecting them. … A few examples of Monocots are Bananas, Palm trees, Grasses, water plantains, Lilies and Orchids.

What is the difference between dicot and monocot leaves?

Both monocots and dicots form different leaves. Monocot leaves are characterized by their parallel veins, while dicots form “branching veins.” Leaves are another important structure of the plant because they are in charge of feeding the plant and carrying out the process of photosynthesis.

Do dicot leaves have spongy mesophyll?

Mesophyll The mesophyll is the ground tissue of leaves present between the upper and lower epidermis of the leaves. The mesophyll is differentiated into palisade parenchyma, and spongy parenchyma in dicot leaves both no such differentiation can be found in monocot leaves.

What is isodose distribution?

In order to represent volumetric or planar variations in absorbed dose, distributions are depicted by means of isodose curves, which are lines passing through points of equal dose. The curves are usually drawn at regular intervals of absorbed dose and may be expressed as a percentage of the dose at a reference point.

What is penumbra in radiotherapy?

Penumbra. The rapid decrease at the edges of the radiation beam is called the penumbra region. Usually defined as the space between the 80% and 20% isodose lines.

What is isodose curve?

An isodose curve (or contour) is a line of constant absorbed dose. The line is in a plane and, for single radi- ation beams, its value is usually related by a simple percentage value (e.g., 90 percent, 80 percent, etc.) to the peak absorbed dose (or the surface absorbed dose, for x rays below 400 kV) on the beam axis.
