Parts of a Plant Cell

Parts of a Plant Cellhttp://cellsalive.com/cells/cell_model.htm

Parts of a Plant Cell1. Cell Wall The outermost part of a plant cell. It is a hard wall that is made up of many sugars ( polysaccharides). It helps the cell maintain its shape and it protects the cell.

2. Cell Membrane Every cell is enclosed by a membrane. The cell membrane is a double layer of lipids (lipid bi-layer) and is also made of proteins. The cell membrane allows materials in and out of the cell.

Parts of a Plant Cell

Parts of a Plant Cell3. Nucleus (membrane bound) The nucleus contains the DNA and directs the cells activities.

Parts of a Plant Cell4. Nuclear Envelope - A membrane that surrounds and protects the nucleus.

Parts of a Plant Cell5. Chromatin - Thin strands in the nucleus that contain genetic material.

Parts of a Plant Cell6. Nucleolus This is where the ribosomes are made.

Parts of a Plant Cell7. Cytoplasm The cytoplasm is the soup inside the cell. The cytoplasm is made mostly of proteins and water. The cell communicates through the cytoplasm.

Parts of a Plant Cell8. Mitochondrion Converts carbohydrates to energy for the cell.

Parts of a Plant Cell9. Endoplasmic Reticulum (membrane bound) It carries material from one part of the cell to another.

Parts of a Plant Cell10. Rough Endoplasmic Reticulum This part of the ER contains ribosomes that were made in the nucleolus. This is the site of protein production.

Parts of a Plant Cell11. Smooth Endoplasmic Reticulum This part of the ER lacks ribosomes and is the site of lipid production.

Parts of a Plant Cell12. Ribosomes These are found on the RER and throughout the cell. Ribosomes are factories that assemble proteins.

Parts of a Plant Cell13. Golgi Body This receives material from the ER for packaging and distributes them to other parts of the cell (the mail room).

Parts of a Plant Cell14. Chloroplasts Large green structures that contain chlorophyll and is the site of photosynthesis. They produce food (carbohydrates) for the cell.

Parts of a Plant Cell15. Vaculoes Large storage area in the cell where food, water, and/or waste is stored.

Parts of a Plant Cell16. Cytoskeleton Protein fibers that aid in the internal movement of cell organelles, as well as muscle fiber contraction.

Parts of a Plant Cell17. Centrosome Aids in cell division.

Parts of a Plant Cell18. Lysosomes Small round structures that contain chemicals that aid in breaking down large food particles into smaller particles.

Parts of an Animal Cell16. Lysosomes See Plant Cell.

Parts of an Animal Cell17. Peroxisome Protects the cell from its own production of toxic chemicals (hydrogen peroxide)

Parts of a Bacterial Cell

Parts of a Bacterial Cell

Parts of a Bacterial Cell1. Nucleoid This is not membrane bound and is generally where the DNA is located. Notice there is no nucleus in a bacterial cell.

Parts of a Bacterial Cell2. Ribosomes See Plant Cell.

Parts of a Bacterial Cell3. Cell Wall See Plant Cell

Parts of a Bacterial Cell4. Cell Membrane (plasma membrane) See plant cell.PEPTIDOGLYCAN LAYER

LIPID BI-LAYER

Parts of a Bacterial Cell5. Pilus These are hair-like structures made of protein that allow bacteria to attach to other cells.

PILUS

Parts of a Bacterial Cell6. Capsule This layer protects the bacterial cell.

Parts of a Bacterial Cell7. Flagella Flagella are made of protein, and they help the bacteria cell move.
