Cell Organelle

Animal Cell

Cell membrane - The thin layer of protein and fat that surrounds the cell.

Centrosome - A small body near the nucleus.

Cytoplasm - The jellylike material outside the cell nucleus where the organelle is located.

Golgi body - a flattened, layered, sac-like organelle that looks like a stack of pancakes - its near the nucleus.

Lysosome - Round organelles with a double membrane.

Nuclear membrane - the membrane that surrounds the nucleus.

Nucleolus - an organelle within the nucleus - it is where ribosomal RNA is produced.

Nucleus - Spherical body con tainting many organelles, including the nucleolus.

Ribosome - small organelles composed of RNA-rich cytoplasmic granules that are sites of protein synthesis.

Rough ER - A vast system of interconnected, membranous, infolded and convoluted sacks that are located in the cell's cytoplasm.

Smooth ER - A vast system of interconnected, membranous, infolded and convoluted tubes that are located in the cell's cytoplasm.

Vacuole - Fluid-filled, membrane-surrounded cavities inside a cell.

Plant Cell

Amyloplast - An organelle in some plant cells that stores starch.

ATP - ATP is short for adenosine triphosphate; it is a high-energy molecule used for energy storage by organisms.

Cell Membrane - The thin layer of protein and fat that surrounds the cell, but is inside the cell wall.

Cell Wall - A thick, rigid membrane that surrounds a plant cell.

Centrosome - A small body located near the nucleus - it has a dense center and radiating tubules.

Chlorophyll - Chlorophyll is magnesium based and it usually green.

Christae - The multiply-folded inner membrane of a cells mitochondrion that are finger-like projections.

Cytoplasm - The jellylike material outside the cell nucleus in which the organelles are located.

Golgi body - A flattened, layered, sac-like organelle that looks like a stack of pancakes and is located near the nucleus.

Granum - A stack of thylakoid disks within the chloroplast is called a granum.

Mitochondrion - Spherical to rod-shaped organelles with a double membrane.

Nuclear Membrane - The membrane that surrounds the nucleus.

Nucleolus - An organelle within the nucleus - it is where the ribosomal RNA is produced.

Nucleus - Spherical body containing many organelles, including the nucleolus.

Photosynthesis - A process in which plants convert sunlight, water, and carbon dioxide into food energy, oxygen and water.

Ribosome - Small organelles composed of RNA-rich cytoplasmic granules that are sites of protein synthesis.

Stroma - Part of the chloroplasts in plant cells, located within the inner membrane of chloroplast between the grana.

Thylakoid disk - Thylakoid disks are disk-shaped membrane structures in chloroplasts that contain chlorophyll.

Vacuole - A large, membrane-bound space within a plant cell that is filled with fluid.

Cell Theory

The cell theory is:

- All living things are made of cells.

- Cells carry out functions needed to support life.

- Cells come only from other living cells.

Prokaryotic and Eukaryotic Cells

Prokaryotic:

- They have no nucleus

- Hereditary contained with cytoplast

- Examples: Archaea and Bacteria

Eukaryotic

- They have a nucleus

- Hereditary contained with the nucleus

- Examples: animals, protist, fungi and plants
