Study Notes
Cell Structure and Function
- Cells are the basic units of life. All living organisms are made of one or more cells.
- Cells are the basic units of structural and organizational biology in all living organisms.
- All cells come from pre-existing cells.
Animal Cells vs. Plant Cells
- Animal cells are typically smaller and more irregular in shape compared to plant cells.
- Plant cells tend to have a boxy or rectangular shape, and they have a cell wall.
- Animal cells do not have a cell wall.
- Animal cells may have multiple, small vacuoles, while plant cells have one large central vacuole.
- Plant cells contain chloroplasts, which are crucial for photosynthesis. Animal cells do not have chloroplasts.
- Both plant and animal cells have mitochondria and other membrane-bound organelles.
Organelles
- Organelles are specialized structures within cells that perform specific functions.
- Examples of organelles include the nucleus, mitochondria, chloroplasts, vacuoles, endoplasmic reticulum, and ribosomes.
- The nucleus contains the cell's DNA, which controls cell activities.
- Mitochondria are responsible for cellular respiration, producing energy for the cell.
- Chloroplasts are found in plant cells and are vital for photosynthesis.
- Vacuoles store water, nutrients, and waste products.
- The endoplasmic reticulum and ribosomes play roles in protein synthesis and transport.
Types of Cells
- Unicellular organisms consist of a single cell, while multicellular organisms have multiple specialized cells organized into tissues, organs, and organ systems.
- Unicellular organisms, like Amoeba and Paramecium, are single-celled organisms that perform all life functions within a single cell
- Multicellular Organisms have different cells with specialized roles, tissues, organs, and systems. For example, animals have a digestive system, respiratory system, and more.
