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

Ribosomes assemble proteins Feature of all cells

Chromatin DNA wrapped around proteins in long thin strands Feature of all cells

Nucleus control center of the cell Contains genetic information in the form of chromatin (chromosomes) Found in eukaryotic cells

Nucleolus found inside the nucleus assembles ribosomes 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

Golgi Apparatus attach carbohydrates and lipids to proteins Found in eukaryotic cells

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

Flagella whip-like projection on the surface of the cell that is moved in a whip-like fashion in order to move the cell Found in both prokaryotic and eukaryotic cells Found in sperms cells of both plants and animals
