GENERAL HISTOLOGY

Detailed explanation-1: -The cell membrane controls what substances pass into and out of a cell. Everything a cell needs, such as food particles, water, and oxygen, enters through the cell membrane.

Detailed explanation-2: -The nucleus is suspended in the cytoplasm in the middle of the cell. This is true both in animal cells and plant cells.

Detailed explanation-3: -The primary functions of the nucleus are to store the cell’s DNA, maintain its integrity, and facilitate its transcription and replication.

Detailed explanation-4: -Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA).

Detailed explanation-5: -The part of the cell that passes on information is the nucleus, which contains DNA. DNA is the genetic material of the cell, which contains all the information for cell structure and function. During DNA replication, the DNA is duplicated and during mitosis the cell splits in two.
