In 1665 Robert Hooke Radolf Virchow Robert Remak( Robert Hooke, Radolf Virchow, Robert Remak ) observed a section of a cork using a primary microscope. That was when he discovered the smallest biological unit of life 'cells'
Radolf Virchow is credited for the third part of the modern cell concept.

During cell division, chromatin is converted into chromosomes.
The main function of the nucleus is control of the cellular activities Production of the ribosome subunits( control of the cellular activities, Production of the ribosome subunits ).

Ribosomes are membrane bound organelles which provide place for protein synthesis.
There are two main parts in the Endoplasmic Reticulum (ER). They are; 1. Rough Endoplasmic Reticulum 2. Soft Endoplasmic Reticulum
The membrane surrounding the vacuole is called the .
Unicellular organisms have contractile vacuoles filled with cell sap.
Plant cell growth has no limit.
During cell division, first the ❌ divides and then, the cytoplasm follows.

Select the correct statements about meiosis from the following.
Help in evolution
An asexual reproduction method
Only shows in diploid cells
Daughter cells receive half the # of chromosomes as the mother cell.
Two divisions take place during the process
In humans and so-like animals, zygote produced by the fusion of the two gametes which are produced from meiosis grows into a multicellular organism by undergoing the process of mitosis.
