Science Question

According to cell theory _____.

all cells have a nucleus
all cells are differentiated
all cells reproduce by mitosis
all living organisms are composed of cells

Answer 1

Hi there! Your answer would be:

D. All living organisms are composed of cells.

Step-by-step explanation:

Not all cells have a nucleus, in fact, an entire species called prokaryotes don't have any at all as a rule!

Also, Not all cells are differentiated. Differentiation is a process when a simple cell turns into a new different cell. Some cells stay simple their whole life.

Mitosis is the process when single-celled organisms split into 2 identical daughter cells. Mitosis only works in single-celled organisms.

Hope this helped!

Answer 2

Heyo, your answer would be D.) All living organisms are composed of cells.

The three parts of cell theory you should remember is that it's considered to be the smallest unit of life, secondly that all living organisms are made up of cells, and lastly that all cells come from other cells (non-spontaneous generation).

Therefore, the answer would be the last option.
