Study Notes
Characteristics of Living Organisms
- Living organisms are complex and organized, consisting of one or more cells
- They are capable of growth and development
- They can reproduce
- They respond to stimuli from their environment
- They require energy to sustain life processes
- They maintain homeostasis, a stable internal environment
- They adapt and evolve over time
Prokaryotic vs. Eukaryotic Cells
- Prokaryotic cells are simple and lack a membrane-bound nucleus and other internal organelles
- Eukaryotic cells are more complex and have a membrane-bound nucleus and other internal organelles
Unicellular vs. Multicellular Organisms
- Unicellular organisms consist of a single cell, carrying out all life processes within that cell.
- Multicellular organisms consist of multiple cells, with specialized cells working together for various functions.
Prokaryotic Cell Characteristics
- Lack a nucleus and other membrane-bound organelles
- Have a single circular chromosome located in a region called the nucleoid
- Smaller in size compared to eukaryotic cells
- Have a cell wall outside the cell membrane
- Found in diverse environments, including bacteria and archaea
Chloroplasts in Plant Cells
- Chloroplasts are organelles responsible for photosynthesis in plant cells
- They contain chlorophyll, a green pigment that absorbs light energy
- This energy is used to convert carbon dioxide and water into glucose (sugar), releasing oxygen as a byproduct.
