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).
Which cell organelle is the largest?
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.
Which is the smallest part of cell?
Ribosomes are tiny organelles found inside cells. Their job is to make proteins.
What is the largest part of a plant?
The root system is often the largest part of the plant because it is responsible for supplying the plant with many of the materials (nutrients, water, oxygen) it needs to survive. Roots can also store food for a plant.
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 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 …
What is the most poisonous plant in the world?
This is what earns the castor oil plant its reputation as the world’s most poisonous. After the laxative oil has been extracted the remaining residues of its mottled brown seeds contain a potent cocktail of toxins. Ricin kills by interfering in cell metabolism, the basic chemical processes needed to sustain life.
Which is the largest flower of the world?
The flower with the world’s largest bloom is the Rafflesia arnoldii. This rare flower is found in the rainforests of Indonesia. It can grow to be 3 feet across and weigh up to 15 pounds! It is a parasitic plant, with no visible leaves, roots, or stem.
Which tree has largest leaf?
The specific palm trees sporting the world’s biggest leaves belong to the Raphia genus, with the crown going to Raphia regalis, which is native to some African countries. Each leaf may be up to 80 feet long and 10 feet wide… taller than many trees! Raffia fibers are collected from the leaves on these trees.
What is the smallest to largest cell?
The 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. The longest cell is the nerve cell.
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.
Which is the longest cell in human body?
Neurons or nerve cells can be up to 3 feet long. A typical neuron has a cell morphology called soma, hair-like structures called dendrites and an axon. Neurons are specialized in conveying knowledge throughout the body. The sensory neurons, motor neurons, and interneurons are three types of neurons.
