INTRODUCTION TO THE CELL
The smallest unit of life
CELLS
instructions that are found on a hereditary material within the nucleus that allows certain organelles to reproduce or replicate when necessary.
Give abbreviation and meaning.
DNA (Deoxyribonucleic Acid)
Which organelle contains digestive enzymes that help it break down food molecules, cell wastes & worn out cell parts when needed. It is the called the cell destroyer.
Lysosome
This organelles is also called the cell barrier.
Cell or plasma membrane
It is a sphere that contains another sphere called a nucleolus
The nucleus
2 types of cells
Prokaryotic and Eukaryotic
Name the more advanced and complex cell type that contains membrane bound structures and make up the human body.
Eukaryotic
The 3 main parts of a cell.
• Cell Membrane
• Cytoplasm
• The nucleus
The organizing and construction center of the cell that is responsible for the division of the cytoplasm when the cell divides.
Centrioles
It’s function: Controls movement of materials in & out of nucleus. It separates the nucleus from the cytoplasm.
Nuclear membrane
Another name for organelles.
Little organs
Give the path a ribosome takes within a human cell.
Produced and released from the nucleolus
Exit the nucleus
Travel along the Rough ERGolgi body packages and exports the finished protein in a vesicle
It is a double layer of lipids and proteins that surrounds a cell and separates the cytoplasm (the liquid contents of the cell) from its surrounding environment.
The cell membrane
Rigid protein substances that forms the Cytoskeleton.
Microtubules/Microfilaments
Another name for this organelle is the powerhouse of the cell.
Mitochondria
All organelles work together to keep the cell alive and they vary in what?
Shape, size & number
Define granular and agranular.
Granular- with ribosomes
Agranular- without ribosomes
Which organelles function is to package, modify and distribute proteins for secretion from the cell. Also, it is closely related to the ER.
Golgi Body
Scaffolding-like or thread like microfilament and microtubules in cytoplasm that form the internal skeleton of a cell.
Cytoskeleton
Another name for this organelle is the master control center of the cell.
Nucleus
Cells provide structure for the body, take in nutrients from food, convert those nutrients into this, and carry out specialized functions.
Energy
ATP (Adenosine TriPhosphate)
What are the 2 types of ER called and what does ER stand for?
Smooth & Rough Endoplasmic Reticulum
Another name for cytoplasm and what is it?
Protoplasm and the jelly like substance that holds the organelles in place.
The function of a ribosome.
The site of protein synthesis.
