cell theory
This scientist first used the term “cell” after observing cork under a microscope.
Who is Robert Hooke?
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?
This is the first phase of mitosis when chromosomes become visible.
What is prophase?
Diffusion is the movement of molecules from an area of ______ concentration to an area of ______ concentration.
high to low
Cell theory states that, "All cells come from...."
What is other 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?
During this phase, chromosomes line up in the middle of the cell.
What is metaphase?
Water moves across a membrane by a special type of diffusion called what?
What is osmosis?
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?
In this final phase, two new nuclei form around the chromosomes.
What is telophase?
Diffusion is a type of this kind of transport that does not require energy.
What is passive transport?
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?
The main reactants of photosynthesis are these three things.
What are carbon dioxide, water, and sunlight?
Before mitosis begins, this phase of the cell cycle occurs, where DNA is copied.
What is interphase?
The main goal of diffusion is to reach this balanced state.
What is equilibrium?
According to Cell Theory, all living things are made of these.
What are cells?
This power making organelle is only in plants and uses sunlight for energy.
The main reactants of cellular respiration are these two substances.
What are glucose and oxygen?
The region where sister chromatids are attached.
What is the centromere?
If molecules move against the concentration gradient, energy is needed — this is called what?
What is active transport?
