Plant Cell There are two classes of cells that exist in biology today, there are prokaryotic cells and there are eukaryotic cells. A prokaryotic cell is a cell that has no nucleus which consists of bacteria; a eukaryotic cell is a cell that has a nucleus. There are two types of eukaryotic cells in biology; plant and animal cells. Plant cells have organelles in each cell that helps then function and go through processes such as photosynthesis. Each cell in our body consists of organelles that help the cell function. All plant cells have a nucleus which consists of a nucleolus, nuclear envelope and nuclear pores. The nucleus is an oval shape which contains the nucleolus and DNA. The process of DNA being altered into RNA takes place within the nucleus; the nucleolus is the site of RNA synthesis and also contains RNA and Protein. The Nuclear envelope consists of two membranes its function is to separate the content within the nucleus from outside of the cell. The nuclear pores control the passage of proteins between the cell’s cytoplasm and plasma of the nucleus. Plants contain certain organelles that animal cells do not contain which is a cell wall which is the cell wall; it functions as the structural support for the plant cell. Other organelles within the animal cell consists of a plasma membrane which is a structure that surrounds all cells, the plasma membrane separates the organelles with in the cell from the Interstitial fluid the plasma membrane also acts as a selective barrier that allows exchanges in and out of the cell. Then there is the Golgi apparatus that consists of flattened membrane stacks which
Cells Plant Cell Animal Cell Both plant and animal cells are eukaryotic cells which mean they have a ‘true’ nucleus. Animal cells can come in an array of sizes and unusual shapes, unlike a plant cell which is typically rectangular or cube shaped. What can be found in a Plant Cell and an Animal Cell? Cell Membrane - This surrounds the cytoplasm in the cell, enclosing its contents. It is thin and semi permeable and allows substances to move through it. Cytoplasm - a gel like substance…
Plant Cell Science Project The following sample plant cell science project experiment is meant to give you ideas on how to perform experiments and arrange your project. Use this project to come up with ideas for your own experiments. Plant Cell Science Project - Plant Cells and Salt The purpose of this sample plant cell science project experiment is to determine how different salt concentrations affect the cytoplasm of plant cells. Background: Research information on plant cells and plant…
roads. In winter time, the pond begins to freeze but the water quality is not much better. Unless there are plants inside, the rest of the pond remains black. Although bone meal includes more phosphorus than most eco-friendly fertilizers, you use less of it to get the same results. Our idea is to encourage maintenance workers to switch to bone meal in the spring time because plants absorb bone meal at a slower rate than regular fertilizers, thus using less and getting the same results. Most…
Plant and Animal Cells Objective The objective of this lab was to learn what a microscope reveals about plant and animal cells. The completion of this lab should teach the participant the differences between plant and animal cells and how to examine samples of the covering tissues of a plant (the onion) and of an animal (the participant) using the epidermis and cells from a cheek swab of epithelial tissue. Materials 1. Packet Pages L14 to L16 2. Onion Chunks 3. Compound Microscope 4. Microscope…
Biology Unit 2 Animal and Plant cells Most cells have some structures in common. They have: A nucleus to control the cell’s activities Cytoplasm where many chemical reactions take place A cell membrane that controls the movement of materials in and out of the cell Mitochondria where energy is released during aerobic respiration Ribosome’s are present where protein synthesis takes place Plant and algal cells also have: A rigid cell wall made of cellulose for support…
difference between plant and animal cells, and what do these cellular differences mean for what plant cells can or can’t do, as compared to animals? How do plants differ from animals in how they solve one of the fundamental problems of being a multicellular organism: how to obtain energy? What are the major tissue types in plants? How do they differ in structure and function? What are the major cell types in ground tissue? How do they differ? What are the two primary organ systems in plants? What are…
Year 8 Science Cells Use the following link to answer the questions and fill in the gaps below. http://www.sheppardsoftware.com/health/anatomy/cell/index.htm Animal Cells Is this cell a Prokaryote or a Eukaryote cell? (Eukaryotoe cell) All animal cells are made up of many cells Some animals, like humans, have trliions of cells, while others, like bacteria are made of just cell. Cells are like little societies in which each orginal performs a Differnet job. Complete the following…
BIOLOGY REVIEW Cells are the basic unit of life and often combine with other cells to form tissues. 3. The image above is of a plant cell. You can tell by the shape of the cell. Plant cells tend to be rectangular shaped while animal cells are circular. Plant cells have a cell wall and have a large central vacuole. 5&7. In the cell cycle, the cell grows and prepares for cell division. The cell is in interphase when it is preparing for division. Cell division involves the splitting of the nucleus…
1 Plants – Lecture 1, Revision question answers Plant cells and tissues 1. a. Describe the structure of a primary cell wall. b. How does a secondary cell wall differ? a. The primary cell wall consists of strands of cellulose that run parallel to each other to form the microfibrils. Various molecules including glycoprotein and pectin form crosslinks between the microfibrils. b. Compared with the primary cell wall the secondary cell wall is thicker and more rigid. The linking material is lignin which…
Chapter 4 Cells as the Basic Unit of Life The Cell Theory Major Contributors: Galileo = first observations made with a microscope Robert Hooke = first to observe small compartments in dead plant tissue, coined the term "cell" Antony van Leeuwenhoek = first to observe living, mobile cells and bacteria Robert Brown = first to observe the nucleus Rudolf Virchow = every new cell comes from a pre-existing cell Schleiden and Schwann = plants and animals…
