Cell theory
What does the M in MRS GREN stand for?
Who is Movement?
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?
Why are cells sometimes likened to LEGO bricks?
Who is 'cells are the building blocks of life'.
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?
Name two parts of cell theory.
- All cells come from pre-existing cells.
- All organisms are made of one or more cells.
- Cells are the basic structural and functional unit of life.
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?
Who was the scientist who discovered cells after he viewed cork under a microscope?
Who is Robert Hooke?
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?
