Homework Answers
1). Onion root tip and whitefish blastula are useful tissues for studying cell division (mitosis) because onion root tip and whitefish blastula are the tissues undergoing high rates of cell division. Cell division is occurring at an accelerated rate in the tip of the onion root. A blastula is an embryonic structure that is growing in size, so cell division is also occuring rapidly. After staining these tissues and observing under a microscope, we can see individual cells at different stages of cell division. So these tissues are moremore conven for study cell division.
2). Plants - tip of the root and stem (because mitosis happens in the meristem of the plant that are located at the tip of the root and stem)
Animals- bone marrow and epithelial tissues
3). 32
No change in chromosome number when it enters prophase from interphase.
4). * Keeps chromosome number constant
* Maintains genetic stability in daughter cells
* Helps in growth and development of zygote
* Helps in repair and regeneration
* Restores nucloplasmic ratio
* Checks cell size and maintains a favourable surface area/volume ratio

5. For this part of the lab you will be observing a whitefish blastula under the microscope. A blastula is a developmental stage in many animals. It occurs shortly after fertilization and the formation of the zygote. It is the “ball of cells” stage of development, where cells are dividing rapidly to form the multicellular organism. Note: In this simulation early and late prophase are combined into one stage: prophase. 1. Go to the Virtual Microscope (Links to an external...

Examine the onion root tip slide images on the following pages. There are four images, each displaying a different field of view. Pick one of the images, and count the number of cells in each stage. Then count the total number of cells in the image. Record the image you selected and counts in Table 2. Calculate the time spent by a cell in each stage based on the 24 hour cycle: Hours of Stage = 24 x Number of...

The series of events that leads to cell division is called the cell cycle. The cell cycle has distinct phases-most of the time, a cell is in itself is divided into three phases: Gl, in which a cell is engaged in the normal activity of thar cell making protcin, gencrating ATT, etc.l; S, the phase when...
