Cells

Cells and Cell Theory- Unit 3

QuestionAnswer
What is an example of a prokaryotic cell? bacteria
Describe a Prokaryotic Cell. the DNA is one long circular chain; it has no nucleus; there are no membrane covered organelles; i's a small cell
Describe a Eukaryotic Cell. it has a nucleus; it has linear DNA; if something is not bacteria- it is Eukaryotic (All other cells: Plants vs Animal)
List the parts of an Animal Cell. nucleus; cell membrane; mitochondria; Golgi complex; lysosome; ribosome; endoplasmic reticulum (smooth & rough); vacuole; cytoplasm; DNA
List the parts of an Plant Cell. nucleus; cell membrane; mitochondria; Golgi complex; lysosome; ribosome; endoplasmic reticulum (smooth & rough); **large vacuole; **cell wall; **chloroplast; cytoplasm; DNA
What is the function of the nucleus? it is the control center of the cell (brain)
What are the functions of the cell membrane? it regulates what enters/exits the cell; it keeps the cell together; it is the outer layer or covering of the cell; phospholipids make up the cell membrane
What are the functions of the mitochondria? they are the powerhouse of the cell and they produce ATP
What is the function of the Golgi Complex? it processes and ships proteins and other materials out of the cell HINT...Fed Ex)
What is the function of a Lysosome? it "engulfs" (surrounds) waste products (old organelles, foreign invaders, wastes); it acts like a clean up crew...HINT: Lysol cleaner
What is the function of a Ribosome? amino acids hook together to form proteins
What are the two types of Endoplasmic Reticulum? Rough ER and Smooth ER
What are the functions of Rough Endoplasmic Reticulum? they have ribosomes; they make lipids; they break down drugs; they package and release proteins for the cell
Describe Smooth Endoplasmic Reticulum. they do not have ribosomes attached
What is the function of a vacuole? it stores water and other excess materials
What is the function of cytoplasm? it is a very watery fluid inside a cell that holds all organelles in place (jelly-like)
What is the function of DNA? it is the blueprints of life and it is found in the nucleus
What is the function of the cell wall? it gives a plant support and structure (only found in plants)
What are the functions of a chloroplast? it makes food using the energy from the sun (only found in plants); traps sunlight and converts it to food; chlorophyll is made and stored here
What are two types of organisms? 1) Multi-cellular 2) Uni-cellular
Describe/Explain Multi-cellular organisms. they are composed of two or more cells (many); the cells can perform various tasks (many functions)
Describe/Explain Uni-cellular organisms. one cell; the one cell cannot perform many types of tasks
Who is Robert Hooke? he discovered cells while looking at a thin slice of cork
Who is Anton Van Leeuwenhook? he made discoveries using his microscope
What did Schleiden, Schwann, and Virchow do? they created the cell theory
What were the parts of the Cell Theory? all organisms are composed of one or more cells; the cell is the basic unit of life in all living things; all cells come from pre-existing cells
