The cell wall holds the whole thing together! Jasmyne S. 7th grade!
No. According to cell theory, the cell is the basic unit of all living things - therefore all living things are made of cells (some are made of a single cell, these are known as unicellular organisms).
All cells except bacteria and archaea are eukaryotic cells. Eukaryotic cells have a true nucleus and other membrane-bound organelles, while bacteria and archaea are prokaryotic cells without a true nucleus. Eukaryotic cells are found in plants, animals, fungi, and protists.
Bacterial cells do have a nucleus. Basically all cells have a nucleus! Bacteria cells are just a different shape like plant cells. If cells didn't have a nucleus they wouldn't be able to work properly!
No, all organs in the body are composed of cells. Cells are the basic building blocks of life and are essential for the functioning of all organs in the body. Each organ is made up of different types of cells that work together to carry out specific functions.
Almost all cells have the same DNA. (e.g. red blood cells don't have DNA, except during early life) They are alive.
true
It is true.
At some time during their lives, all cells must contain DNA.
No. Most cells are replaced eventually, but not all cells every day.
True, NK cells are there to protect the body from any type of abnormal growth in all tissues including cancer cells.
Out of all of those statements, the only true statement is that all cells come from other cells. Cells do not stop producing themselves once one reaches adulthood and organs do not make cells in the body. Also, cells do not depend on the brain to create more cells.
Thats correct Their cells have nuclei. -
In fact the opposite is true. Cellular reproduction is what causes other cells that make up Tissues, and therefore make up Organs from Tissues are what make cells.
Yes, some cells are terminally differentiated and are no longer capable of dividing. These include mature nerve cells and muscle cells. However, most cells in the body, such as skin cells and blood cells, are capable of division.
False. Not all human cells can bind or have a receptor for each hormone. Different cells express different types of receptors, allowing specific cells to respond to specific hormones.
Cells in the kingdom plantae do have a nucleus. This is true for all Eukaryotic cells. Plant cells have an enclosed nucleus.
No. According to cell theory, the cell is the basic unit of all living things - therefore all living things are made of cells (some are made of a single cell, these are known as unicellular organisms).
