Basic Cell Structure
š All cells share three common components: a cell membrane (separating inside from environment), cytoplasm (jelly-like fluid), and DNA (genetic material).
𧬠There are two broad categories: eukaryotic cells (complex, possess a nucleus and organelles, found in plants/animals) and prokaryotic cells (unicellular, lack a nucleus or membrane-enclosed organelles, like bacteria).
š¬ Organelles are specialized parts within the cell performing unique jobs, such as the nucleus being the cell's control center.
Key Organelles and Functions
āļø The nucleus contains DNA (genetic material); when condensed for division, it forms chromosomes, and the nucleolus manufactures ribosomes.
š Ribosomes are responsible for synthesizing proteins and can float freely or attach to the endoplasmic reticulum (ER).
š The ER acts as a transport passageway; rough ER has ribosomes, while smooth ER does not.
š¦ Materials exit the ER in vesicles to the Golgi apparatus, which customizes and folds proteins into usable shapes, sometimes adding lipids or carbohydrates.
ā”ļø The mitochondrion is the powerhouse, generating energy via ATP molecules through cellular respiration; energy-demanding cells have more mitochondria.
ā»ļø Lysosomes act as garbage collectors, using enzymes to break down damaged cell parts.
Plant Cell Specifics and Cell Movement
āļø Plant cells possess chloroplasts, which are the site of photosynthesis due to the green pigment chlorophyll.
š”ļø Plant cells have a cell wall outside the membrane for shape, support, and protection; animal cells never have a cell wall.
š Plant cells often have a central vacuole primarily used for water storage.
š¬ļø Some cells have specialized projections: cilia (hair-like projections that move in waves, trapping inhaled particles) and flagella (tail-like structures aiding in cell movement, like in sperm cells).
Key Points & Insights
ā”ļø The fundamental distinction between cell types lies in the presence of a nucleus and membrane-enclosed organelles (Eukaryotes vs. Prokaryotes).
ā”ļø Protein synthesis is a multi-step process involving the nucleus (ribosome creation), ribosomes (synthesis), ER (transport), and Golgi apparatus (modification/folding).
ā”ļø Energy production relies on the mitochondrion performing cellular respiration to create ATP.
ā”ļø All cells maintain structure via the cytoskeleton, which includes protein microfilaments and microtubule tubes.
