What is the function of micronucleus?
The micronucleus regulates reproduction and the macronucleus regulates the vegetative functions in paramecium. The micronucleus is the smaller nucleus in ciliate protozoans.
Do atoms contain smaller particles?
Atoms contain positively charged nucleus at the centre and negatively charged electrons revolving around the nucleus. The nucleus consists of positively charged protons and neutral neutrons. All atoms except positron (an isotope of hydrogen) have atleast one neutron.
Which particle is smaller a proton molecule atom or nucleus?
A proton is smaller than a nucleus, which is smaller than an atom, which is again smaller than a molecule.
Cells contain smaller parts known as organelles. The nucleus, chloroplasts, mitochondria, and vacuoles are all examples of organelles. What do these organelles have in common?
They are all enclosed by a membrane.
Is nucleus smaller than atom?
An atom comprises an atomic nucleus with orbiting electrons. So the nucleus is smaller than an atom. To phrase it the opposite way, an atom is alwys larger than the nucleus (of the same atom of course!!)
What is the function of micronucleus?
The micronucleus regulates reproduction and the macronucleus regulates the vegetative functions in paramecium. The micronucleus is the smaller nucleus in ciliate protozoans.
Are protists smaller than bacteria?
protist are bigger because they contain a nucleus
Which of the following are one-celled organisms with no nucleus?
Cells without nucleus are called Prokaryotic cells. In addition, they contain no membrain bounded organells, they are smaller in size, they contain peptidoglycan, no vacuoles, and reproduction is assexual (binary fission or conjugation)
Whats the difference in function between the macronucleus and the micronucleus?
The macronucleus is the larger of the two types ofnuclei in ciliate protozoans. It controls all cell functions except reproduction. The micronucleus is smaller and controls the reproductive functions.
Do atoms contain smaller particles?
Atoms contain positively charged nucleus at the centre and negatively charged electrons revolving around the nucleus. The nucleus consists of positively charged protons and neutral neutrons. All atoms except positron (an isotope of hydrogen) have atleast one neutron.
Particle found in nucleus?
The main constituents of the nucleus are protons and neutrons, but each of these is made up of smaller particles known as quarks.
Which particle is smaller a proton molecule atom or nucleus?
A proton is smaller than a nucleus, which is smaller than an atom, which is again smaller than a molecule.
Cells contain smaller parts known as organelles. The nucleus, chloroplasts, mitochondria, and vacuoles are all examples of organelles. What do these organelles have in common?
They are all enclosed by a membrane.
Which one is the smaller structure a nucleus or a cell?
A cell nucleus would be smaller than a cell because a cell nucleus is inside the cell, so it has to fit inside.
Why is the RNA in the cytosol much smaller than the RNA in the nucleus?
In the nucleus, RNA is transcribed from the entire gene. The genes contain both introns and exons. Only the exons contain the coding information for the protein. After transcription these long RNAs (called hnRNA) are processed to remove the introns. After adding a poly A tail, and a cap on the 5' end, the now much smaller RNA is exported into the cytosol where it can be translated.
Is nucleus smaller than atom?
An atom comprises an atomic nucleus with orbiting electrons. So the nucleus is smaller than an atom. To phrase it the opposite way, an atom is alwys larger than the nucleus (of the same atom of course!!)
Why is the nucleus not have electrons?
because the nucleus is not an atom; an atom is smaller than a cell
