Transcript of Cell Organelles. Features Found in all Cells Cell membrane Cytoplasm DNA ribosomes.
Cell Membrane
• control center of the cell
• Contains genetic information in the form of chromatin (chromosomes)
• Found in all cells
Cytoplasm
• jelly-like substance found between the nuclear envelope and the cell membrane in which all the organelles are embedded
• Feature of all cells
Nucleus
• control center of the cell
• Contains genetic information in the form of chromatin (chromosomes)
• Found in eukaryotic cells
Nuclear Envelope
• a membrane around the nucleus that controls what enters and leaves the nucleus
• Found in eukaryotic cells
Smooth Endoplasmic Reticulum
• contains enzymes that have specialized tasks like making lipids and other parts of the cell membrane
• no ribosomes attached
• Found in eukaryotic cells
Rough Endoplasmic Reticulum
• has ribosomes attached
• modifies proteins that are made in the ribosomes
• Found in eukaryotic cells
Mitochondrion
• changes food into energy that can be used by the cell in a process called cellular respiration
• “power house” of the cell
• Found in eukaryotic cells
Chloroplast
• contain the green pigment chlorophyll
• carries out photosynthesis
• Found in eukaryotic cells
• Found in plant and protist cells only
Centrioles
• aid in cell reproduction (mitosis & meiosis)
• separate and serve as a starting point for the formation of spindle fibers (sort of like a scaffold)
• Found in eukaryotic cells
• Not found in plant cells
Cell Wall
• provides support and protection to the cell
• Found in both eukaryotic and prokaryotic cells
• Found in plant, fungi, and some protist cells, but not animal cells
Lysosomes
• “suicide organelle,” contain digestive enzymes
• pick up wastes and toxins and destroy them.
• If the cell gets sick and cannot repair itself, the lysosomes release the digestive enzymes into the cell and destroy it. Can also be genetically programmed to do this
• Found in eukaryotic cells• Not found in plant cells
Vacuole
• a saclike structure that stores water, salts, proteins, carbohydrates and other substances in cells
• Found in eukaryotic cells
• Small ones can be found in animal cells
Large Central Vacuole
• stores large amounts of water
• Found in eukaryotic cells
• found in plants only
Cilia
• short hair-like projections on the surface of the cell that are moved in a wave-like motion in order to move the cell or move objects like food toward the cell
• Found in both prokaryotic and eukaryotic cells
• Usually found in bacteria, protists, & animals
