⚙️Cells are the fundamental units of life, serving as the building blocks of all living organisms.
🧬Cells contain a nucleus, which houses DNA, the genetic blueprint that guides cellular activities.
🌿Plant cells have additional structures such as cell walls and chloroplasts, enabling photosynthesis.
🔬Proteins are synthesized by ribosomes in cells, playing essential roles in tissue building and repair.
🔄Cell division through mitosis allows organisms to grow, repair tissues, and maintain balance.
What is a cell?
—A cell is the smallest functional unit of life, serving as the building block of all living organisms.
What is the function of the nucleus?
—The nucleus houses DNA, the genetic material that contains instructions for all cellular activities.
What are the unique features of plant cells?
—Plant cells have additional structures such as cell walls and chloroplasts, enabling them to perform photosynthesis.
Why are proteins important in cells?
—Proteins are essential for building and repairing tissues and perform various functions within the cell and throughout the body.
How does cell division contribute to organism growth and repair?
—Cell division, through a process called mitosis, allows organisms to grow, repair damaged tissues, and maintain a healthy balance.
