Which is the second largest cell organelle present in plant cell?

In green alga, chloroplasts are of various shapes and sizes but chloroplasts of higher plants are disc-shaped with a diameter of 4 to 6 micrometre and thickness of 2 to 4 micrometre. In embryophytes, they are the second-largest cell organelle, smaller only to the nucleus.

Which is the largest cell organelle present in plant cell class 9?

Chloroplast is the largest organelle present in the cell. It is 10 micrometer long and 2 micrometers thick. It is mainly present in the plant cells and involved in the process of photosynthesis.

Which is the largest organelle present in cell?

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 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 smallest organelle?

The smallest organelle in the cell is the ribosome.

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.

Which hold the organelles is called?

As its name suggests, the cytoskeleton is like a cellular “skeleton.” It helps the cell maintain its shape and also helps to hold cell structures such as organelles in place within the cytoplasm. Figure 5.5. 2: Cytoskeleton. The cytoskeleton gives the cell an internal structure, like the frame of a house.

Do plant cells move?

Although plants (and their typical cells) are non-motile, some species produce gametes that do exhibit flagella and are, therefore, able to move about. …

Do plant cells have Nucleoid?

In plant cells, the nucleus contains DNA and controls the functions of the cell. … Unlike the nucleus in plant cells, the nucleoid in bacterial cells is not held within a membrane. The nucleoid refers to an area in the cytoplasm where strands of DNA congregate. In bacteria, DNA form a single, circular-shaped chromosome.

What is the smallest cell?

Answer: A cell is described as the smallest, basic unit of life in charge of all the processes of life. 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.

What is the smallest part of a cell?

Ribosomes are tiny organelles found inside cells. Their job is to make proteins.

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.
