Mitochondria are the powerhouse of the cell because they supply power (energy) to all the cell of the body.
All living cells have mitochondria (cell organelle), are responsible for producing energy (called ATP) that the cell needs to function.
They are like power stations in our bodies, supplying energy to all cells for proper functioning.
If our cells do not have energy, then the tissues or body organs that are made up of cells do not work properly, in the same way that if power stations do not produce enough energy for the country there will be areas of blackout, where parts of the country cannot function.

Yogita Ingle 7 years ago

Groups can be marginalised Becoz of three reasons:
1) Several groups can be marginalised because of their language.
Their language is different from the majority language. Hence the majority marginalised that group

2) Several groups can be marginalised because of their dressing sense as they think that their old dresses are better than the new ones.

3) Becoz of their thinking style as they lack it and they think in their own way.

Cytoplasm is a thick jelly-like fluid inside the cell membrane. Nearly 80% of the cytoplasm is water. It occupies the space between the cell membrane and the nucleus. All the life functions take place in the cytoplasm. There are many small cytoplasmic bodies in cytoplasm. These are called cell Organelles. All organelles in cytoplasm play an active role in the functioning of the cell.

Why all planets revolve around the sun.

Posted by Ritik Bhardwaj Bhardwaj 7 years ago

CBSE > Class 08 > Science

1 answers

Meghna Thapar 5 years, 5 months ago

All eight planets in the Solar System orbit the Sun in the direction of the Sun's rotation, which is counterclockwise when viewed from above the Sun's north pole. Six of the planets also rotate about their axis in this same direction. The gravity from the sun causes our planet to move in a curved, elliptical path. Thankfully, the planets are moving fast enough so that they are not pulled into the sun, which would destroy Earth. On the other hand, we are also not moving quickly enough to escape the sun's pull.

Why all planets are round.

Posted by Ritik Bhardwaj Bhardwaj 7 years ago

CBSE > Class 08 > Science

1 answers

Meghna Thapar 5 years, 5 months ago

A planet is round because of gravity. A planet's gravity pulls equally from all sides. Gravity pulls from the center to the edges like the spokes of a bicycle wheel. This makes the overall shape of a planet a sphere, which is a three-dimensional circle. Our planets have continued spinning because of inertia. In the vacuum of space, spinning objects maintain their momentum and direction their spin because no external forces have been applied to stop them.
