Cell Theory
This scientific theory states that all living things are made of cells, cells are the basic unit of life, and all cells come from preexisting cells.
Cell Theory
These two types of cells both contain ribosomes, cytoplasm, and a cell membrane.
prokaryotic and eukaryotic cells
This structure is found in both prokaryotic and eukaryotic cells and is responsible for making proteins.
Ribosomes
This stage of the cell cycle includes G1, S, and G2 phases where the cell grows, copies DNA, and prepares for mitosis.
Interphase
This can occur when the cell cycle is no longer properly regulated.
Cancer
Scientific theories do not become these, because laws describe while theories explain.
Scientific Law
This organelle is found in plant cells and is responsible for photosynthesis.
Chloroplast
The plasma membrane is described this way because it controls what enters and exits the cell.
Selectively Permeable
During this phase of mitosis, chromosomes line up in the middle of the cell.
Metaphase
Mitosis is important because it maintains this in new cells during asexual reproduction.
Chromosome Number
This structure controls what enters and leaves the cell and acts as a highly selective barrier.
Cell Membrane
This organelle is known as the “powerhouse of the cell” because it produces energy.
Mitochondrion
This type of transport moves materials across the cell membrane without using energy and includes diffusion and osmosis.
Passive Transport
This process divides the cytoplasm and completes cell division after mitosis.
Cytokinesis
Because mitosis produces genetically identical cells, it contributes to this level of genetic variation.
Limited genetic variation
This type of microscope produces a three-dimensional image of the surface of a specimen.
Scanning Electron Microscope (SEM)
Unlike eukaryotic cells, prokaryotic cells do not contain this membrane-bound organelle.
Nucleus
This transport process requires energy to move substances against the concentration gradient, such as the sodium-potassium pump.
Active Transport
This type of cell division is used by prokaryotes like bacteria.
Binary Fission
These abnormal masses form when cells grow and divide uncontrollably, and they may be benign or malignant
Tumors
This invention allowed scientists like Hooke and Van Leeuwenhoek to observe cells for the first time.
Microscope
This large storage organelle is especially prominent in plant cells.
Central Vacuole
These three structures are unique to plant cells and help with support, photosynthesis, and storage.
Cell Wall, Chloroplasts, and Central Vacuole
In this phase, sister chromatids separate and move to opposite sides of the cell.
Anaphase
Unlike normal cells, cancer cells often ignore these signals that tell cells to stop dividing.
