Cell Growth and Division

Cell Growth and Division. Cell Growth. When a living thing grows, what happens to its cells? Does an animal get larger because each cell increases in size or because it produces more of them ? In most cases, living things grow by producing more cells

Lesson Overview

Lesson Overview. 10.1 Cell Growth, Division, and Reproduction. Limits to Cell Size. What are some of the difficulties a cell faces as it increases in size? The larger a cell becomes, the more demands the cell places on its DNA .

Chromosomes structure and Cell cycle

Chromosomes structure and Cell cycle. Genetic Material in the Living Cells. In a non-dividing cell the nucleus is filled with a thread-like material known as "chromatin". Chromatin is made up of DNA and proteins (mainly histones and some non-histone acidic proteins).
