Question

1)What is prokaryotic and eukaryotic cell?
2)Define nucleus of a cell.
3)what function did nerve cell perform?

Answer 1

A prokaryote is a unicellular organism that lacks a membrane-bound nucleus, mitochondria, or any other membrane-bound organelle


Eukaryote, any cell or organism that possesses a clearly defined nucleus. The eukaryotic cell has a nuclear membrane that surrounds the nucleus, in which the well-defined chromosomes (bodies containing the hereditary material) are located. Eukaryotic cells also contain organelles, including mitochondria (cellular energy exchangers), a Golgi apparatus (secretory device), an endoplasmic reticulum (a canal-like system of membranes within the cell), and lysosomes (digestive apparatus within many cell types).

The nucleus is an organelle found in eukaryotic cells. Inside its fully enclosed nuclear membrane, it contains the majority of the cell'sgenetic material. This material is organized as DNA molecules, along with a variety of proteins, to form chromosomes.

Nerve Cells. Neurons are nerve cells that originate, process, transmit, and receive nerve impulses. They are connected to other neurons or to cells in muscles, organs, or glands.
