Question: How does mitosis produce new cells‚ and how is mitosis the same and different? Materials: - Compound microscope - Alliums root slide - Whitefish embryo slide - Power supply Procedure: Refer to page 48 and 49 in the textbook. Results: See attached sheet for drawings of my results. Discussion: Analyze and interpret question 1 and 2 on page 49. 1. The cells in the root tip region of the alliums differ quite a bit from the cells that are found deeper in the root

Cell Transformation Cell transformation is when a cell takes in DNA from the outside of the cell. It then becomes a component of the cell’s DNA. There are three different ways in transforming the cells. There is transforming bacteria‚ transforming plant cells‚ and transforming animal cells. The purpose of cell transformation is to introduce a foreign plasmid in order to make large quantities of it. In transforming bacteria‚ a foreign DNA is first joined to a small circular DNA molecule known

Our assignment is about how chromosomes separate and how cell division works through microtubules and histones. DNA in the nucleus is loose and not well defined into chromosomes because it is usually tightly coiled‚ but in the interphase nucleus the chromatin exists in two forms: loosely coiled form called euchromatin and tightly coiled formed called heterochromatin. These two types become more coiled to form the chromosome at the time of cell division. DNA is a bit loosely coiled in the euchromatin

Vacuoles and Vesicles Vesicles are small bubbles found inside most living cells. They are created during natural processes like endocytosis‚ or the release of materials from a cell. One reason they are important is because they organize a cell’s nutrients. A crucial building block for living cells is one type of vesicle called a vacuole. A vacuole is essentially a membrane surrounding a mass of absorbent fluid. Vacuoles are found in all plant cells‚ most animal cells‚ and some bacterial cells

Antibiotics are chemicals produced by living organisms that are used to kill or inhibit the growth of other infectious micro-organisms. Most antibiotics prevent the growth of microorganisms‚ which they act on instead of completely killing them. Antibiotics are extra cellular products meaning that they can be extracted for use; Penicillin is an example of this as it comes from the fungus Penicillium notatum. Hormones are chemicals that transfer information and instructions between cells in animals
