Report Abuse. The largest cell organelle is Nucleus, on a general scale. The next largest cell organelle is Chloroplast , present only in plant cells on the other hand Mitochondria is the second largest in animal cells. Their might be a number of exceptions depending on various species of cells.
What is the second largest organelle in a cell?
In animal cell Mitochondria is second largest cellular organelle, but Chloroplast(Plastids) are much larger than Mitochondria.
Is the nucleus the largest organelle?
The nucleus, the largest organelle in eukaryotic cells, is surrounded by two membranes, each one a phospholipid bilayer containing many different types of proteins. The inner nuclear membrane defines the nucleus itself.
Which is the largest cell organelle in a cell?
Note: 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 nucleus is the largest organelle within animal cells. The nucleus controls cell activity. It also contains the cell’s chromosomes.
Which is largest cell?
The 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 largest cell structure?
The nucleus is the largest cellular organelle, and the only one visible using a light microscope. Much like the cytoplasm of a cell is enclosed by a plasma membrane, the nucleus is surrounded by a nuclear envelope that separates the contents of the nucleus from the contents of the cytoplasm.
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.
Is the nucleolus an organelle?
The nucleolus: an organelle formed by the act of building a ribosome.
Does the nucleus contain DNA?
The nucleus contains the cell ‘s DNA and directs the synthesis of ribosomes and proteins. Found within the nucleoplasm, the nucleolus is a condensed region of chromatin where ribosome synthesis occurs. Chromatin consists of DNA wrapped around histone proteins and is stored within the nucleoplasm.
Which organelle is called suicidal bags of cell?
50 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 …
Which cell is the smallest cell?
Answer:
- The Cerebellum’s Granule Cell is the smallest cell in the human body that is between 4 micrometers to 4.5 micrometers long.
- The RBC ‘s size also found roughly 5 micrometers.
- Most scientists suggest that sperm is the smallest cell in terms of volume.
What is the smallest part of a cell?
Ribosomes are tiny organelles found inside cells. Their job is to make proteins.
Which is the smallest organelle in a cell?
The 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 is the largest cell in human body?
The 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 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.
