PLANT CELL VS ANIMAL CELL

1. PLANT CELL AND ANIMAL CELL

2. LET’S RECALL! A. Identify the following pictures by naming the level of biological organization it belongs . 1. 2. 3. 4. 5. 6. 7. 8. 9.

3. B. Arrange the following levels of biological organization from least up to the most complex level. Number the following from 1-9. ______ Tissue ______ Biosphere ______ Organism ______ Organ ______ Cell ______ Ecosystem ______ Community ______ Organ System ______ Population

4. What is a cell?

5. Let us try to complete the following statement that would help us describe a cell. A  cell  is the ______ unit of life that is responsible for all of life's processes . *Clue for the answer is the antonyms of complex.

6. Let us try to complete the following statement that would help us describe a cell. A  cell  is the basic unit of life that is responsible for all of life's processes . *Clue for the answer is the antonyms of complex.

7. CELL • The cell (from Latin cella , meaning "small room") is the basic structural, functional, and biological unit of all known organisms. • A cell is the smallest unit of life. • Cells are often called the "building blocks of life".

8. Two classification of cell: Prokaryotic cell - are unicellular organisms that lack organelles or other internal membrane-bound structures. Therefore, they do not have a nucleus, but, instead, generally have a single chromosome: a piece of circular, double-stranded DNA located in an area of the  cell  called the nucleoid. ex. Bacteria and archaea

9. 2. Eukaryotic cell – contains membrane-bound organelles such as a nucleus, mitochondria, and an endoplasmic reticulum. examples: protists , fungi, plants, and animals (everything except  prokaryotes ) Take note: Organelles are tiny organs that perform important life processes in the cell

10. PLANT CELL VS. ANIMAL CELL PLANT CELL Plant cells  are the basic unit of life in organisms of the kingdom Plantae. They are eukaryotic  cells , which have a true nucleus along with specialized structures called organelles that carry out different functions. 

11. PARTS OF A PLANT CELL Ribosome

12. ANIMAL CELL Animal cells  are typical of the eukaryotic  cell , enclosed by a plasma membrane and containing a membrane-bound nucleus and organelles. Unlike the eukaryotic  cells  of plants and fungi,  animal cells  do not have a  cell  wall.

13. Parts of an Animal Cell or vacuole

14. Basic Parts and Functions of a Cell Cell wall - The primary function of the cell wall is to protect and provide structural support to the cell. It is made of cellulose. 2. Cell Membrane/Plasma Membrane – It encloses the cell and separates what is inside it from its environment. It also controls what goes in and out of the cell. 3. Cytoplasm - It consist of the jelly-like structure where all the other parts of the cell are located. 4. Nucleus - Is an oval structure that is the control center of the cell. It also contains materials that play a role in heredity. 5. Endoplasmic Reticulum – transport protein to different parts of the cell.

15. 2 types of Endoplasmic Reticulum: * Rough Endoplasmic Reticulum - is an organelle where most of the ribosomes are attached. It is involved in protein synthesis. * Smooth Endoplasmic Reticulum - is a branching canal (without ribosomes) that transports large molecules inside the cell. It also enables lipid synthesis. 6. Ribosomes - Are small granular structures attached to the surface of the endoplasmic reticulum. It helps produce proteins 7. Golgi Apparatus/Golgi bodies - A stack of flattened sacs located very close to the endoplasmic reticulum. It modify, sort and package proteins produced in the ribosomes that are embedded in the RER. 8. Vesicles - Are organelles that carry materials in and out of the cell.

16. 9. Mitochondria - Are small, double-membraned, spherical, or sausageshaped organelles involved in the production of energy. The energy produces by the mitochondria is important for the vital activities of the cell such as growth and reproduction. 10. Vacuoles - Are large, round, water-filled sac floating in the cytoplasm. Plant cells contain large vacuoles, called central vacuoles while animal cells contain a small vacuole. It stores food, enzymes, and other materials needed by the cell. 11. Cytoskeleton - Is a network of thin and fibrous filaments that serve as the “bones and muscles” of cells.

17. 12. Lysosomes - Are small round structures responsible for the digestive activities of the cell. It removes harmful substances inside the cell by breaking down waste products and old worn-out cell parts. 13. Chloroplast - Chloroplast are irregularly shaped green structures that contain a green pigment called the chlorophyll. Chlorophyll captures the energy of sunlight and uses it for food production of a plant cell. Chloroplast is present only in plant cell. 14. Centriole – only found in animal cells that functions during cell division.

18. Activity #1 Comparing Plant Cell and Animal Cell Direction: Fill in the Venn diagram to compare PLANT CELL and ANIMAL CELL . Use the word in the word box. Cell wall Lysosome Nucleus Centriole Mitochondria Chloroplast Smooth ER Cell membrane/Plasma Membrane Ribosome Golgi Body/Golgi Apparatus Vacuole/vesicle Cytoskeleton Cytoplasm Rough ER

19. ORGANELLES PLANT CELL ANIMAL CELL Cell wall Present Absent Cell Membrane/Plasma Membrane Present Present Cytoplasm Present Present Nucleus Present Present Endoplasmic Reticulum (Smooth and Rough ER) Present Present Ribosomes Present Present Golgi Apparatus/Golgi bodies Present Present Mitochondria Present Present Vacuole/Vesicle Present (Large known as vacuole) Present (small and known as vesicle) Lysosomes Present Present Chloroplast Present Absent Centrioles Absent Present

20. EVALUATION: Direction. Identify the parts of the cell that is being describe. The powerhouse of the cell. Transport proteins to different part of the cell. Controls all the activities of the other parts that occur within the cell. An organelle involved in the manufacturing of protein. It functions during cell division. Regulates what enters and leaves the cell. Maintains cell shape. Responsible for breaking down and absorbing materials taken by the cell. Contains all organelles and site of most cell activity. Serves as storage of water and food. Gives shape and protection to plant cell. Prepares proteins for use or export. Contains green pigment called chlorophyll that is important for food production of plant. It has attached ribosomes that manufacture protein. No attached ribosomes and involved in the manufacturing of fats and lipids.
