Xylem transports only minerals and waters from the roots. Phloem transports food materials that are prepared by the green parts of the plants to other parts of the plant. (I love u)... Xylem is the dead tissues at maturity, but no cell contents. Phloem is the living tissue, but not with the nucleus.

Yogita Ingle 5 years, 6 months ago

Transport of soluble product of photosynthesis or food from leaves to other parts of plants is called translocation.

For translocation, food molecules enter the part of the phloem called the sieve tubes where they can be transported upwards or downwards to all parts of the plant including roots.

It is the way from where sperms reach ovaries

0Thank You

Yogita Ingle 5 years, 6 months ago

The Fallopian (or uterine) tubes are two tubes that extend from the uterus towards the ovaries.

The Fallopian tube has three sections: the narrow isthmus that connects with the uterus, the broader ampulla in the middle, and the flared infundibulum with fimbriae that serve to direct the released ovum from the ovary towards the uterus.

Generally, fertilisation of the ovum with sperm takes place within the ampulla, after which the fertilised ovum is conducted to the uterus for nidation (implantation).

Yogita Ingle 5 years, 6 months ago

Saliva is a fluid which is secreted by the salivary glands. It helps in digestion of food by following Ways.

Saliva contains a digestive enzyme called salivary amylase, which converts carbohydrates in to maltose sugars.
It cleans the mouth cavity and tends to destroy germs that cause teeth decay. It contains lysozomes which help in destroying the bacteria.
It moistens and lubricates food which again helps in swallowing.
It acts as solvent, dissolving some food particles to stimulate taste buds of the tongue.

explain all 4 types of structure of heart in different vertebrates

Posted by Sudarshan Bhope 5 years, 6 months ago

CBSE > Class 10 > Science

1 answers

Meghna Thapar 5 years, 5 months ago

Both birds and mammals have 4 chambered hearts. Both the atrial and ventricular regions of the heart are divided. This allows complete separtation of the pulmonary circuit from the systemic circuit.

Amphibians have a three-chambered heart - two atria and one ventricle.

The heart is roughly triangular in shape. It has four compartments called chambers inside it. The upper two chambers of the heart are called atria and the lower two chambers are called ventricles. The atria receive blood from the two main veins. The left atrium is connected to the left ventricle through a valve V1 and the right atrium is connected to the right ventricle through another valve V2. These valves prevent the backflow of blood into atria when the ventricles contract to pump blood out of the heart to the rest of the body because when the ventricles contract, the valves V1 and V2 close automatically so that the blood may not go back into the atria. The job of heart is to pump blood around our body. All the atria and ventricles of the heart contract and relax at appropriate times and make the heart behave like a pump. A sheath of tissue called pericardium protects the muscular heart.

Posted by Reena Rani 5 years, 6 months ago

1 answers

Yogita Ingle 5 years, 6 months ago

AC generator, also known as alternators, is a machine that converts mechanical energy into electrical energy. The generated electrical energy is in the form of an alternating current sinusoidal output waveform. The mechanical energy is usually supplied by steam turbines, gas turbines and combustion engines.

AC generators work on the principle of Faraday’s law of electromagnetic induction which states that electromotive force -EMF or voltage – is generated in a current carrying conductor that cuts a uniform magnetic field. This can either be achieved by rotating a conducting coil in a static magnetic field, or by rotating the magnetic field that contains the stationary conductor. The preferred arrangement is to keep the coil stationary because it is easier to draw induced alternating current from a stationary armature coil than a rotating coil..
