Cell Theory
This scientist first used the term “cell” after observing cork under a microscope.
Robert Hooke
Found in both plant and animal cells and controls the movement of substances in and out of the cell
cell membrane
Found in plant but not animal cells and provides protection and structure for the cell.
cell wall
This is the first phase of mitosis when chromosomes become visible.
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...."
other cells
Transports proteins throughout the cell and acts as a conveyor belt.
endoplasmic reticulum
Plant cells have a larger one of these because they need more storage of what.
vacuole and water
During this phase, chromosomes line up in the middle of the cell.
metaphase
Water moves across a membrane by a special type of diffusion called what?
osmosis
According to the cell theory, a cell is _________________.
the most basic unit of life.
This a jelly-like substance that fills the cell and helps it hold its shape.
cytoplasm
This cell is circular in shape and does not have a cell wall.
animal cell
In this final phase, two new nuclei form around the chromosomes.
telophase
Diffusion is a type of this kind of transport that does not require energy.
passive transport
This scientist that discovered animal tissues are made up of cells.
Theodor Schwann
This small organelle is often referred to as the factory worker making proteins
ribosomes
The main reactants of photosynthesis are these three things.
carbon dioxide, water, and sunlight
Before mitosis begins, this phase of the cell cycle occurs, where DNA is copied.
interphase
The main goal of diffusion is to reach this balanced state.
equilibrium
According to Cell Theory, all living things are made of these.
cells
This power making organelle is only in plants and uses sunlight for energy.
chloroplast
The main reactants of cellular respiration are these two substances.
glucose and oxygen
The region where sister chromatids are attached.
centromere
If molecules move against the concentration gradient, energy is needed — this is called what?
active transport
