Chapter 10 Cell Growth and Division

Chapter 10 Cell Growth and Division. Cell Growth. A. A living thing grows because it produces more and more cells. 1. The cells of a human adult are no larger than the cells of a human baby, but there are more of them.

Chromosome Terminology

Chromosome Terminology. Chromosome = 2 replicated DNA strands. Centromere = place where sister chromatids remain attached and kinetochore forms. Kinetochore = proteinaceous structure where microtubules attach. Chromatid = one DNA strand. Chromatid (sister).

Chapter 8 Cellular Transport & Cell Cycle

Chapter 8 Cellular Transport & Cell Cycle. 8.1 Cellular Transport. Osmosis- diffusion of H 2 O H 2 O moves freely through plasma membrane H 2 O tries to maintain equal concentration on both sides of plasma membrane Control of Osmosis Concentration gradient- unequal distribution of particles.
