mitosis; this is because they’re in the tip of the root which is an area of the plant that grows quickly. This results in more cells going through mitosis all at once‚ also allowing us to examine the different stages of mitosis. Stages: 1. Interphase: DNA replicates‚ but has not formed the condensed structure. They remain as loosely coiled chromatin. The nucleus is still intact. 2. Prophase: The DNA molecules progressively shorten and condense by coiling‚ to form chromosomes. The spindle

Mitosis & Meiosis In science class this week‚ we’ve been learning about cell reproduction. What is Cell division? What is Mitosis? What is Meiosis? How are they alike? How do they differ? All of these amazing questions will be answered‚ if you decide to read on. The Cell Cycle A life cycle begins with an organism’s formation‚ followed by its growth and development‚ and the production of offspring that will repeat the cycle‚ before ending in death. Right now‚ I am in a stage in the life

Chapter 10 Notes Pt. 2 The division of nuclear material in which each new nucleus obtains the same number of chromosomes and the same nuclear code as the original nucleus is call mitosis. Mitosis occurs in four phases. Interphase occurs between mitosis. Interphase: Cell contains easily seen nucleus and nucleolus- chromosomes appear as fine dots within nucleus Mitosis: 4 steps Prophase – cell nucleus enlarged –nucleolus no longer visible- chromosomes appear as short strands within nucleus

a type of cell division. In mitosis a parent cells chromosomes are copied and separated into two cells with different nucleuses but same DNA. There are steps or phases that take place that make the cell divide. The first phase is called Interphase. In interphase there are sub groups such as gap 1‚ 2 and synthesis‚ also known as S. In gap 1 protein synthesis occurs and the cell grows and may double in size. In S stage DNA of the parent cells are copied‚ and the long loose fibers are called chromatin

several phases during the cell cycle. The experiment obligated pictures of onion root tips under the microscope. The pictures had cells and chromosomes. The pictures also had different phases of mitosis in them. As my hypothesis‚ cells stay in the interphase the longest. To begin the experiment‚ there were pictures of the microscopic cells of an onion root tip. There are four images‚ each displaying a different view. First I needed to pick one of the images‚ count the number of cells in each stage
