Cellular growth involves a cell cycle with distinct phases: interphase consisting of G1, S, G2 where the cell grows and DNA is replicated; mitosis where the cell divides into two daughter cells through the phases of prophase, metaphase, anaphase and telophase; and cytokinesis where the cell physically separates the daughter cells. The cell cycle results in cell reproduction, growth, replacement and repair.
Mitosis pp presentation for gr 10 life sciencesAiden
This is a simple yet detailed presentation on the process of how a cell divides called Mitosis.
It elaborates on why a cell undergoes Mitosis: Growth, Repair, and Reproduction.
An easy way to remember Mitosis is by the acronym IPMAT

cell division - Mitosis in plants final.pptReddykumarAv
mitosis is used for almost all of your body’s cell division needs. It adds new cells during development and replaces old and worn-out cells throughout your life. The goal of mitosis is to produce daughter cells that are genetically identical to their mothers, with not a single chromosome more or less.

Continuation of the cell structure and function. This presentation highlights the cell cycle and concentrate on how cell division occur and the steps involved in cell dividing.

The ability of organisms to produce more of their own kind is the one characteristic that best distinguishes living things from nonliving matter. This unique capacity to procreate, like all biological functions, has a cellular basis. The continuity of life is based on the reproduction of cells, or cell division. Cell division plays several important roles which are giving rise to a new organism, enabling development, renewing and repairing and also replacing damaged tissue is multicellular organisms.
توانایی موجودات زنده در تولید بیشتر از نوع خود یکی از ویژگیهایی است که موجودات زنده را از مواد غیر زنده به بهترین وجه متمایز می کند. این ظرفیت منحصر به فرد برای تولید مثل، مانند همه عملکردهای بیولوژیک، دارای پایه سلولی است. تداوم زندگی براساس تولید مثل سلولها یا تقسیم سلولی است. تقسیم سلولی چندین نقش مهم را ایفا میکند که نه تنها باعث ایجاد یک ارگانیسم جدید میشود، همچنین امکان رشد، تجدید و ترمیم و همچنین جایگزینی بافت آسیب دیده موجودات چند سلولی را نیز فراهم می کند.
This is a simple worksheet for drawing and outlining the stages of mitosis. There are 4 boxes for Prophase, Metaphase, Anaphase, and Telophase with 1 extra box for either interphase or cytokinesis.
Grade 9 Biology. Introduction to the cell cycle. These are the guided notes for the Cell Cycle PPT. The goal is to introduction the stages of the cell cycle. G1, S, and G2. There is a lot of space for diagrams. Students are asked to consider surface-area to volume ratio and size limitations for the cell. Additionally, they should be able to identify the differences between each stage of the cell cycle and interphase.
4. Why are cells so small?
• Most cells are less than 100µm (100x10^-6)
5. Ratio of surface area to volume
• Why is increased surface area so
important to cells?
– Transport
• More proteins
• Greater diffusion of substances
• Increased reaction rates
• Greater diffusion of waste material
– Cellular Communications
• Signaling proteins

10. Main Ideas
• All living organisms are composed of
cells.
• Cells divide to increase their numbers
through a process of mitosis, which
results in two daughter cells with
identical sets of chromosomes.
13. Introduction
• Most cells in an organism go through a
cycle of growth, development, and division
• Goal: Grow, develop, replace old or
damaged cells, produce new cells
