Cell Theory
According to cell theory, this is the basic unit of structure and function in all living things.
The cell.
This characteristic of life describes an organism’s ability to grow and develop over time.
Growth and development.
Plants and animal cells both contain an organelle that controls what enters and leaves the cell. What is the name of this organelle?
Cell membrane
This organelle is responsible housing organelles, providing structural shape, and facilitating the transport of materials
Cytoplasm.
Cell theory says that all cells come from this.
From pre-existing cells.
This characteristic allows living things to react to changes in their environment.
Respond to stimuli.
This organelle makes food for the organism through a process called photosynthesis.
Chloroplast.
This organelle is responsible for directing all activities like growth, metabolism, and reproduction.
Nucleus.
This tool made it possible for scientists to discover cells and develop the cell theory.
The microscope.
The ability of living things to produce offspring is called this.
Reproduction.
This organelle is responsible for cellular respiration?
Mitochondria
Freddy Krueger's cells can’t convert food energy effectively into energy they can use. As a result, he gets extremely tired, has weak legs, and can’t breathe well. Freddy swims every day to keep his body as strong as possible. Which organelle is affected by Freddy's disease?
Mitochondria.
According to cell theory, this is the basic unit of structure and function in all living things.
The cell.
This characteristic of life means that living things can maintain a stable internal environment.
Homeostasis.
This organelle provides support and structure for plants.
Cell wall.
Plant cells need both a cell membrane and a cell wall. Why?
The cell wall provides structural support.
The cell membrane regulates what can enter and exit the cell.
what are scientists like Schleiden, Schwann, or Virchow known for?
These scientists helped develop the cell theory after using microscopes to study living things.
Living things are able to change over long periods of time through this process.
Evolve and adapt.
Michael Myers decides to try out for track. He decides to not eat lunch on the day of the first try out because he is nervous. During the warm up mile run, he becomes dizzy and faints. Why did this happen to Michael Myers?
Michael did not feed his mitochondria.
This organelle contains DNA and controls cell activities by regulating gene expression and protein production.
Nucleus.
