Comparing Plant and Animal Cells Problem: How are plant and animal cells alike? How are they different?

To examine plant and animal cells

The role of Chromosomes in heredity Comparison of plant and animal cells Today you will use prepared slides to investigate the phases of mitosis in both plants and animals. Longitudinal sections of the root of Allium, will be used to examine the cells in the root meristem, the growing region of the root.

Whole mounts of whitefish blastula will illustrate reproductive cells in animals. These undifferentiated cells undergo mitosis at a regular interval as the embryo increases in number of cells and complexity.

You will make observational drawings and be prepared to take a practical quiz. The fundamental life processes of plants and animals depend on a variety of chemical reactions that occur in specialized areas of the organism's cells.

As a basis for understanding this concept: Students know how prokaryotic cells, eukaryotic cells including those from plants and animalsand viruses differ in complexity and general structure. All living organisms are composed of cells, from just one to many trillions, whose details usually are visible only through a microscope.

Students know the characteristics that distinguish plant cells from animal cells, including chloroplasts and cell walls. Students know the nucleus is the repository for genetic information in plant and animal cells. Students know cells divide to increase their numbers through a process of mitosis, which results in two daughter cells with identical sets of chromosomes.

Students know that as multicellular organisms develop, their cells differentiate. Plant and Animal Mitosis Your objective: Find and make observations of cells in each phase of mitosis in plant and animal tissue. Compare the differences between plant and animal mitosis.

Be able to correctly identify the phases from both plant and animal tissue. Prepared slide labeled 'Allium root, mitosis' Prepared slide labeled 'whitefish blastula, mitosis' compound microscope Procedures: Set up your microscope, place the onion root slide on the stage and focus on low 40x power.

Focus at x and re center so that you are focused on the more 'square' meristem cells. Slowly move the slide and search for cells in each phase of mitosis When you have found one, make a detailed observational drawing of that cell.

Label all important structures nucleus, chromosome, cell plate. Title the drawing with the type of cell, magnification, and phase of mitosis. Continue with your observations until you have found cells in each phase and both you and your partner can easily identify each phase.

Remove the onion root slide and replace it with the whitefish blastula slide.

Essay on To Examine Plant and Animal Cells Title: To examine an animal and Animal and plant cells both transport protein into and out of cells through endoplasmic reticulum and have vacuoles where food, water, and nutrients are stored as well as provide stability for a plant. Microscope Lab Comparing Plant and Animal cells Objectives: · Explain how to properly handle the microscope. · Recognize the differences in structure between plant and animal cells · Identify and observe cells and cell structures Materials: microscope slides Examine the microscope and give the function of each of the parts listed in the. Comparing Plant and Animal Cells Purpose: To compare the structures of a typical plant cell (Elodea) and a typical animal cell (human). Part A: Examining Plant Cells examine it under low power. Look for a group of cells. 4) On your answer sheet, draw what the cells look like on high power.

Focus and center at 40x, x, and x magnification. As instructed above, locate and make observational drawings of each phase of mitosis.Examine the two drawings of animal cells below.

Plant cells all had a cell wall which the animal cell lacked. Plant cells were larger in size compare to the animal cell Any other valid point perhaps one about shape? marks) Below are two cells. Cell Nucleus Teacher Resources. Find Cell Nucleus lesson plans and worksheets. Showing 1 - of resources.

Fifth graders examine plant and animal cells. In this plant and animal cell instructional activity, 5th graders define what cells are, label their parts, and describe how plant and animal cells are different.

The advancement of light microscopy also required methods for preserving plant and animal tissues and making their cellular details more visible The fluorescence microscope is used to examine structures that bind special fluorescent dyes. It can be used. COMPARING PLANT AND ANIMAL CELLS INTRODUCTION: Animal and plant cells share characteristics, which you will observe in this lab.

To examine plant and animal cells

They also differ in several important ways. Examine the cells, first under middle power, then under high power. At first, the field of view will be light blue and the cells will be a slightly darker blue.

Kindergarten Cell Structure and Function. The student will investigate the structure and function of plant and animal cells Key: I.

Tissue Preparation

Assemble and take apart objects to . Tissue Preparation The advancement of light microscopy also required methods for preserving plant and animal tissues and making their cellular details more visible, methods collectively called histotechnique (from histo, meaning "tissue").

In brief, classical histotechnique involves preserving a specimen in a fixative, such as formalin, to prevent decay; embedding it in a block of paraffin and.
