Study Notes
Cell Structure and Functions
- Cells contain materials essential for carrying out vital life processes.
- Major functions of cells include metabolism, respiration, reproduction, growth, excretion, and movement.
Major Life Processes
-
Metabolism involves chemical reactions within cells, categorized into:
- Catabolism: Breakdown of molecules to release energy.
- Anabolism: Synthesis of complex molecules from simpler ones.
-
Respiration is crucial for energy production, classified into:
- Aerobic: Requires oxygen.
- Anaerobic: Occurs without oxygen.
-
Reproduction occurs through:
- Mitosis: Cell division resulting in identical cells.
- Meiosis: Cell division that produces gametes for sexual reproduction.
-
Growth includes:
- Cell Division: Process by which cells produce new cells.
- Intussusception: Growth from within living organisms.
- Accretion: Growth in non-living things through external substance addition.
-
Excretion is the removal of metabolic waste products that include:
- Carbon dioxide, water, mineral salts, and nitrogenous wastes.
- Organs involved in waste elimination: skin, lungs, liver, kidneys, large intestine, and urinary bladder.
-
Movement is also referred to as:
- Motility or Locomotion, essential for various cellular activities.
Subcellular Organelles
- Cells possess subcellular organelles that perform specialized functions.
- Organelles are enclosed in membranes and include structures like ribosomes, nuclei, and chloroplasts.
- These organelles are essential for maintaining cellular processes and can be observed under high magnification using an electron microscope.
