Do ribosomes contain DNA?
Ribosomes do not contain DNA.
Ribosomes are composed of 2 main sub-units – the large subunit joins together the mRNA and the tRNA forming polypeptide chains whereas the smaller RNA subunits reads RNA..
Which organelle is called suicidal bags of cell?
lysosomes50 years ago, Christian de Duve introduced the term “suicide bags” to describe lysosomes (1), the organelles containing numerous hydrolases, which were, until the discovery of the ubiquitin-proteasome system, thought to be responsible for the major part of the intracellular turnover of proteins and other macromolecules …
What is powerhouse of cell?
Mitochondria are tiny organelles inside cells that are involved in releasing energy from food. This process is known as cellular respiration. It is for this reason that mitochondria are often referred to as the powerhouses of the cell.
Which is biggest animal cell?
ostrichCaulerpa taxifolia is the largest animal cell. it is an aquatic alga. Largest animal cell is ostrich eggs measuring about 170*135 mm in diameter.
Which part of the cell is non living?
cell wallComplete answer: In a plant cell, the cell wall is the only part that is non-living because it is an extracellular product and exists outside the living boundary of the cell i.e. the plasma membrane and protects the cell besides providing it a definite shape.
Which organelle is not present in animal cell?
The cell wall is not present in the animal cells and they have only the cell membrane. Plant cells contain large vacuoles that occupy a major portion of the cells. The vacuoles of plant cells provide strength and mechanical support. Animal cells show only the presence of small vacuoles or sometimes they are absent.
What is the smallest and largest cell organelle?
Answer Expert Verified The name of the smallest cell organelle is Ribosomes and the largest one is called nucleus.
Which is the largest cell?
ovumThe largest cell is ovum in the human body. The ovum also called egg cell is the reproductive cell in the female body. Ovum is 20 times bigger than the sperm cells and has a diameter of about 0.1 mm.
Which is the world’s smallest cell?
MycoplasmaThe smallest cell is Mycoplasma (PPLO-Pleuro pneumonia like organims). It is about 10 micrometer in size. The largest cells is an egg cell of ostrich.
What is the smallest human cell?
spermThe sperm is the smallest cell in human biology, but also one of the most complex. The egg meanwhile is the largest cell and similarly intricate. Looking further out into the natural world, the diversity of these sex cells, or gametes, is truly remarkable. Most species have two gametes, which we term male and female.
Which is the largest cell in human body?
ovumThe human egg (ovum) is the largest cell in the body and a nerve cell is the longest cell in the human body. The sperm is the smallest cell in human biology, but also one of the most complex.
Is acetabularia the largest plant cell?
Ovule of cycas is the largest cell among the multicellular plants. The unicellular marine alga Acetabularia, can reach upto 10 cm in height.
Which is the largest cell organelle in cell?
nucleusNote: The largest cell organelle, in general, is considered to be the nucleus. Though in plant cells, the vacuole takes up about 80-90% of the volume, thus being the largest cell organelle in a plant cell.
What is the largest organelle?
The largest organelle in a cell is the nucleus; the next largest would be the chloroplast— only found in plant cells—which is substantially larger than a mitochondrion. The smallest organelle in a cell is the ribosome (the site for the manufacture of proteins within the cell).
Is mitochondria the largest cell organelle?
In animal cell Mitochondria is second largest cellular organelle, but Chloroplast(Plastids) are much larger than Mitochondria. So in Plants, Chloroplast becomes second largest organelle and third largest organelles of plant cell is thus Mitochondria.
Is cytoplasm an organelle?
Cytoplasm is not a cell organelle. It is simply a generic term that describes everything within the plasma membrane and outside of the nucleus. We typically think of cell organelles as being within the cells.
What was the first organelle to be discovered?
nucleusIn 1833, Brown observed and described the nucleus, the first organelle. In 1838, the many and various observations were converted into a cell theory by Schleiden, who proposed that all plant tissues were composed of nucleated cells.
Which is the smallest cell organelle?
ribosomeThe smallest organelle in the cell is the ribosome. The diameter of the ribosome is about 20 nm. It is made up of small and large subunits.
Which organelle is known as the brain of the cell?
The nucleus is often referred to as the control center, or brain, of the cell and contains the DNA, or genetic material. The nucleus is surrounded by the nuclear envelope.
Which organelle is called kitchen of the cell?
PlastidsPlastids are recognized as Kitchen of the cell. Plastids are double-membrane organelles which are found in the cells of plants and algae. Plastids are responsible for manufacturing and storing food.
