Eukaryotic cell contains membrane bound nucleus whereas prokaryotic cell don?t. Both eukaryotic and prokaryotic and eukaryotic cells contain nucleus (or nucleolus) which contains genetic material in m i.e. both DNA and RNA in m.

Size and shape of cells vary with functions y perform. In unicellular organism a single cell constitutes entire organism. The components in all eukaryotic cells are more/less same. Centrioles are present in animal cells but absent in plant cells.

Rudolph Virchow was first scientist who explained that new cells arise from pre-existing cells. This finding was added into cell ory which was originally formulated by Schleiden and Schwann.

Cell wall provides mechanical supports and avoids rupture of cell in a hypotonic solution. Plasmodesmata are tiny hole like structures that connects cell walls of adjacent cells and facilitates communication between cells. Cell wall is entirely permeable and rigid.

Based on position of centromere, chromosomes can be classified into four types. The metacentric chromosome has its centromere in middle, thus forming two equal arms of chromosome.

The secondary wall of cell wall does not face adjacent plant cell. It grows inwards, hence facing cell membrane of same cell. It diminishes growth of cell wall of young cells.

Motile bacteria have a thin filamentous structure extending from cell known as flagella. Flagella are made of three parts – filament which is longest portion, hook and basal body.

Adjacent plant cells adhere to each or due to presence of middle lamella. However, plasmodesmata pass through middle lamella and connect cytoplasm of two cells.

Matthias Schleiden, a German botanist and Theodore Schwann, a British zoologist toger formulated cell ory. Rudolph Virchow introduced his ory of Omnis cellula-e cellula, thus giving final shape to cell ory.

In year 1838, German botanist Matthias Schleiden observed different types of cells present in plant tissue of various plants. Along with Schwann, he formulated cell ory.
