Study Notes
Prokaryotic Cells
- Lack a nucleus and membrane-bound organelles
- Considered structurally simpler than eukaryotic cells
- Examples include bacteria
Eukaryotic Cells
- Have a nucleus and membrane-bound organelles
- Considered structurally more complex than prokaryotic cells
- Examples include animal, plant, and fungal cells
Plant Cells
- Possess unique organelles like chloroplasts, a cell wall, and a large central vacuole
- Chloroplasts are responsible for photosynthesis
- Cell wall provides structural support and protection
- Large central vacuole stores water and nutrients
Animal Cells
- Lack chloroplasts, cell walls, and large central vacuoles
- Possess lysosomes, which break down waste materials
Both Plant and Animal Cells
- Share common organelles including the nucleus, vacuoles, endoplasmic reticulum, ribosomes, Golgi apparatus, mitochondria, and the cell membrane
- Nucleus houses the cell's genetic material (DNA)
- Vacuoles store water, nutrients, and waste products
- Endoplasmic reticulum (ER) is involved in protein and lipid synthesis
- Ribosomes are responsible for protein synthesis
- Golgi apparatus modifies, sorts, and packages proteins and lipids
- Mitochondria generate energy for the cell through cellular respiration
- Cell membrane controls what enters and exits the cell
Cell Theory
- All living things are composed of one or more cells.
- Cells are the basic unit of life.
- All cells arise from pre-existing cells.
Evidence for Cell Theory
- Cells can be observed under a microscope.
- Cells reproduce asexually through budding, as seen in yeast cells.
Testing Cell Theory
- Observations:
- Cells obtain energy.
- Cells develop and grow.
- Cells produces waste.
