Cell Biology – 10th Grade Notes
What is a Cell?
• Cell Definition: The smallest unit of life. All living organisms are made up of one or
more cells. Cells carry out all necessary functions for survival, like energy
production, reproduction, and growth.
Types of Cells:
• Prokaryotic Cells:
o Simple cells without a nucleus. Found in organisms like bacteria.
o Example: Bacteria are a great example of prokaryotic cells. They don’t have
a nucleus but are highly efficient at surviving in different environments.
• Eukaryotic Cells:
o These cells are more complex and have a nucleus. Found in plants, animals,
and fungi.
o Example: Animal Cells – These contain structures like mitochondria, a
nucleus, and ribosomes.
Cell Organelles:
• Nucleus:
o Controls the cell’s activities by holding the genetic material (DNA).
• Mitochondria:
o Known as the powerhouse of the cell, converting nutrients into usable
energy.
Cell Division:
• Mitosis:
o The process of cell division that produces two identical daughter cells. This
process is important for growth and healing.
o The stages are: Prophase, Metaphase, Anaphase, and Telophase.

Genetics and Evolution – 10th Grade Notes
DNA and Genes:
• DNA (Deoxyribonucleic Acid):
o DNA carries the genetic code that tells the cells how to make proteins. These
proteins determine your physical traits.
o Structure: DNA is made up of nucleotides, which consist of a sugar, a
phosphate group, and nitrogenous bases: Adenine, Thymine, Cytosine, and
Guanine. These bases pair specifically: A with T, and C with G.
Mendelian Genetics:
• Dominant and Recessive Traits:
o Dominant Traits: Traits that appear even if only one copy of the gene is
present.
o Recessive Traits: Traits that appear only if both copies of the gene are the
same.
• Punnett Squares:
o A tool used to predict the probability of offspring inheriting specific traits
from their parents.
Evolution:
• Natural Selection:
o The process where organisms with beneficial traits survive and reproduce.
Over generations, these traits become more common in the population.
