cell theory
This is the second part of cell theory.
What is cells are the basic unit of structure and function in living things?
This organelle is found in both plant and animal cells and controls the movement of substances in and out of the cell
What is the cell membrane?
This organelle is found in plant but not animal cells and provides protection and structure for the cell.
What is the cell wall?
After his observations under a microscope, he coined what he saw "cells" because they looked like monk rooms.
Who is Robert Hooke?
This is the definition of endosymbiotic theory.
The theory that explains the origin of eukaryotes. Mitochondria and chloroplast were former prokaryotes that were engulfed by other prokaryotes. This engulfing lead to a symbiosis and development of eukaryotic cells.
This is the third part of cell theory.
What is cells come from pre-existing cells?
This organelle transports proteins throughout the cell and acts as a conveyor belt.
What is an endoplasmic reticulum?
Plant cells have a larger one of these because they need more storage of what.
What is a vacuole and water?
This belief, that life just "poofed" into existence, was held for over 2,000 years.
What is spontaneous generation?
Prokaryotes lack these two things.
What are:
1. Nucleus
2. Membrane-bound organelles
These two scientists concluded that all plants and animals are made of cells.
Who are Matthias Schleiden and Theodor Schwann?
This a jelly-like substance that fills the cell and helps it hold its shape.
What is cytoplasm?
This cell is circular in shape and does not have a cell wall.
What is an animal cell?
Plant cells have these three organelles that animal cells do not.
What are:
1. Cell wall
2. Chloroplast
3. Large Central Vacuole
This is the organelle pathway of protein synthesis.
What is nucleus-->endoplasmic reticulum/ribosome-->vesicle-->Golgi body--> cell membrane
This scientist added the idea that all cells come from other cells.
Who is Rudolf Virchow?
This small organelle is often referred to as the factory worker making proteins
What are ribosomes?
This organelle makes the ribosomes.
What is the nucleolus?
Animal cells have these two organelles that plant cells do not.
What are:
1. Centrioles
2. Lysosomes
What does pro and kary mean in prokaryotes?
What is before/nucleus?
This is the first part of cell theory.
What is all living things are made of cells?
This power making organelle is only in plants and uses sunlight for energy.
This organelle assists with cell division.
What are centrioles?
This is the scientists that developed endosymbiotic theory.
Who is Lynn Margulis?
How long ago did the first prokaryotic cell and eukaryotic cell form?
What are 3.8 and 2 billion years ago?
