Cell Organelles

Prokaryotic Cells A prokaryotic cell lacks a nucleus and membrane-bound organelles. A prokaryotic cell lacks a nucleus and membrane-bound organelles. Contains single strand DNA in a ring. Contains single strand DNA in a ring. Contains ribosomes. Contains ribosomes.

Eukaryotic Cells Eukaryotic cells are found in all organisms except in the Kingdoms Eubacteria and Archaebacteria. Eukaryotic cells are found in all organisms except in the Kingdoms Eubacteria and Archaebacteria. They contain a “true nucleus” and membrane bound organelles. They contain a “true nucleus” and membrane bound organelles. An organelle is a tiny organ found in cells. An organelle is a tiny organ found in cells.

PARTS OF A CELL Plasma (cell) membrane Cell Wall Cytoplasm Nucleus Nucleolus Nuclear membrane Ribosomes Endoplasmic Reticulum Golgi Apparatus Centriole Mitochondria Lysosome Vacuole Chloroplasts

The Plasma Membrane is like the SKIN of the cell. The Cell Membrane controls what enters and leaves the cell.. Copyright © Arizona Board of Regents

The Nucleus is like the BRAIN of the cell. The nucleus is the control center of the cell. It contains the genetic information for the cell in the form of DNA called chromatin. It is a membrane bound structure usually found in the middle of the cell.

Nucleolus Inside Nucleus Produce ribosomes

The Mighty

The “Mighty” Mitochondria is the POWERHOUSE of the cell. Mitochondria - Makes energy in the form of ATP ATP are produced to “power” the cell. The mitochondria are thought to have once been a bacteria that was taken into animal cells and eventually became part of the cell.

Vacuoles are the STORAGE SPACES for cells. These are membranous sacs that can store food, enzymes, wastes, and other materials needed by the cell. Plant cells have large vacuoles for water storage. Copyright  Tupperware Worldwide

Cytoplasm Jello-like substance where organelles are embedded.

The Cell Wall is like a suit of ARMOR around the cell. Cell Wall - Supports the cell. It is found in plant cells NOT animal cells.

Chloroplasts are where PHOTOSYNTHESIS occurs. Contain chlorophyll, a green pigment that traps the energy from light. Found in plant cells and some protists, NOT found in animal cells.

The Golgi Apparatus is the PACKAGING CENTER of the cell. Golgi Apparatus - Packages and modifies proteins.

The Endoplasmic Reticulum is the cells DELIVERY SYSTEM. Endoplasmic Reticulum (ER) - Delivers proteins. A membranous tubular system throughout the cell connecting the nuclear membrane to the cell membrane.

Lysosomes Specialized vacuole that contains digestive enzymes.

Ribosomes Protein synthesis (makes proteins)

Centrioles Centrioles help in cell division. They are found only in animal cells.

Differences in Plant Cells & Animal Cells

Plant Cells have a cell wall large vacuoles for water storage chloroplasts for photosynthesis

Animal Cells Vacuoles are smaller Centrioles for cell division

Plant vs. Animal Cell
