Cell Organelles
This organelle is known as the 'powerhouse of the cell'.
What is the mitochondrion?
This structure controls what enters and exits the cell.
What is the cell membrane?
These structures, found in plant cells but not in animal cells, help support and maintain the shape of the cell.
What are cell walls?
According to cell theory, all living things are composed of these.
What are cells?
This process involves cells using oxygen to convert glucose into energy.
What is cellular respiration?
This organelle stores genetic material.
What is the nucleus?
This process describes the movement of water across a semipermeable membrane.
What is osmosis?
his green organelle is present in plant cells and is responsible for photosynthesis.
What is a chloroplast?
This part of the cell theory states that cells are the basic unit of ______ and ______ in organisms.
What is structure and function?
This simple form of cell division results in identical daughter cells.
What is mitosis?
These organelles are like the cell’s recycling centers, breaking down waste.
What are lysosomes?
This type of cell transport does not require energy.
What is passive transport?
Plant cells often have one large central ______ for storage, while animal cells may have smaller forms of these.
What is a vacuole?
According to cell theory, all cells come from this process.
What is pre-existing cells?
During this cellular process, the cell's DNA is copied before cell division.
What is DNA replication?
This organelle is responsible for making proteins within the cell.
What are ribosomes?
This specialized protein assists in transporting substances across the cell membrane.
What is a transport protein?
Unlike plant cells, animal cells have these structures, which help in cell division.
What are centrioles?
These scientists are credited with founding the cell theory.
Who are Schleiden and Schwann?
This process happens in the chloroplasts and converts sunlight into chemical energy.
What is photosynthesis?
This organelle helps with lipid production and detoxification.
What is the smooth endoplasmic reticulum?
The movement of particles from an area of low concentration to high concentration requiring energy is called this.
What is active transport?
Plant cells can make their own food using light energy in a process called _________.
What is photosynthesis?
This scientist added the concept of 'omnis cellula e cellula' or 'every cell from a cell' to cell theory.
Who is Rudolf Virchow?
This process causes cells to communicate with each other to perform specific functions.
What is cell signaling?
