Question

Fill in the blanks.
i) Cell _________ are contained in cytoplasm.
ii) _________ cell does not have a nuclear membrane.

Answer 1

Hint: The cell is the biological, structural and functional unit of life. The smallest unit of like is known as a cell. Cytology is the study of cells. Cells are often termed as building blocks of life.

Complete step by step answer: Cytoplasm is a gel like structure that is situated inside the cell membrane. It is jelly in structure so that the movement of other cell organelles and the transport of cellular material could easily take place. The cytoplasm is often termed as protoplasm. All the cell organelles are present inside the protoplasm. The cell organelles like nucleus, mitochondria, chloroplast, endoplasmic reticulum, ribosomes and many others are present in the cytoplasm.
The prokaryotic cells are the cells which do not have any true nucleus or any membrane bound cell organelles. The word pro means before and karyon means nucleus. These are the simplest forms of life present on the earth and are the first living beings. The prokaryotic cells are the organisms like mycoplasma, Archaea and Bacteria.
Thus, according to the above explanation, the blanks should have-
-Cell Organelles are contained in cytoplasm.
-Prokaryotic cells do not have nuclear membranes.

Additional Information:
The prokaryotic cells have a nucleoid region, but the nucleus is absent, whereas in eukaryotic cells, a membrane bound nucleus is present. The size of prokaryotic cells are smaller, likely to be less than 5 micrometers, as compared to the eukaryotic cells, whose size is between 10- 100 micrometers. The prokaryotes are usually unicellular and the eukaryotes are multicellular.

Note:
The plant and animal cell could be easily distinguished from one another. The cell wall is present in plants but absent in animals. The plant cells consist of large vacuoles but are smaller in number, whereas in animal cells, the vacuoles are more in number but the size is smaller.
