Study Notes
Cell Structure and Functions
- Protoplasm consists of all the cellular components including cell membrane, cytoplasm, and nucleus.
Common Cell Components
- Cell Membrane: Present in both animal and plant cells, it regulates the movement of substances in and out of the cell.
- Cytoplasm: A gel-like substance filling the cell, contains cytosol and organelles.
- Nucleus: Found in both cell types, acts as the control center containing genetic material.
Unique Components
- Cell Wall: Unique to plant cells; provides structure and protection. Absent in animal cells.
- Lysosome: Found only in animal cells; contains digestive enzymes for waste processing.
- Chloroplast: Present only in plant cells; site of photosynthesis converting sunlight into food.
- Centrioles: Found in animal cells, involved in cell division; absent in plant cells.
Common Organelles in Both Cell Types
- Ribosomes: Sites of protein synthesis.
-
Endoplasmic Reticulum (ER):
- Rough ER: Studded with ribosomes for protein synthesis.
- Smooth ER: Lacks ribosomes, involved in lipid synthesis and detoxification.
- Golgi Body: Modifies, sorts, and packages proteins and lipids for secretion.
- Mitochondria: Known as the powerhouse of the cell, involved in energy production.
- Vacuole: Storage sac for nutrients, waste, and other materials.
- Cytoskeleton: Provides structural support and aids in cell movement.
Summary of Differences
-
Animal Cells:
- No cell wall or chloroplasts.
- Contain lysosomes and centrioles.
-
Plant Cells:
- Have a cell wall and chloroplasts.
- Lack lysosomes and centrioles.
