Cells And Tissues Test - 7

The shape and size of a cell depends on the functions that it performs.

Fungi are multicellular eukaryotic organisms.

Robert Hooke first observed dead cells, whereas Leeuwenhoek first reported free living cells. Purkinje coined the term 'protoplasm'.
The first cell theory is credited to the work of Theodor Schwann and Matthias Jakob Schleiden in 1830s.

A plant cell wall is composed of a polysaccharide known as cellulose. Cellulose is the most abundant organic polymer on Earth.

This is the correct answer. Movement of solvent across the plasma membrane from a region of lower concentration of solute to a region of higher concentration of solute is known as osmosis.

Lysosome is a single membrane-bound cell organelle. Cell organelles like mitochondria and chloroplast are double membrane-bound organelles.

The rod-shaped structures in nucleus, which are visible at the time of cell division, are known as chromosomes.

RER looks rough under a microscope because of the presence of ribosomes.

A eukaryote is any organism whose cells contain a nucleus and other organelles enclosed within membranes.

This statement is false. An animal cell is a form of eukaryotic cell that makes up many tissues in animals.

Nucleolus is a non-membrane-bound structure that is composed of proteins and nucleic acids. It is the largest structure in the nucleus of eukaryotic cells, where it primarily serves as the site of ribosome synthesis and assembly.

Nucleolus is that part of a nucleus which is responsible for the complete functioning of the nucleus and thus, it is equivalent to the nucleus of a cell, and not the cytoplasm.

Cytoplasm is present between nucleus and cell membrane and holds all the other cell organelles.

The largest cell measuring 170 mm × 130 mm is the egg of an ostrich.

In an egg, a white material surrounds the yellow part. The white material is protein, known as albumin, which solidifies on boiling.
