Study Notes
Plant and Animal Cells
- Plant cells have a cell wall, animal cells do not.
- Plant cells have chloroplasts, animal cells do not.
- Plant cells have a large vacuole, animal cells do not.
- Plant cells have a regular shape, animal cells have an irregular shape.
- Plant cells have a nucleus at the side, animal cells have the nucleus at the center.
Plant and Bacterial Cells
- Plant cells have mitochondria, bacterial cells do not.
- Plant cells have no flagellum, bacterial cells have a flagellum.
- Plant cells have no plasmids, bacterial cells have plasmids.
- Plant cells have no capsules, bacterial cells have capsules.
- Plant cells have a nucleus, bacterial cells do not.
- Plant cells have no pili, bacterial cells have pili.
- Plant cells have chloroplast, bacteria cells do not.
- Plant cells have large vacuoles, bacterial cells do not.
Organelles and their functions
- Mitochondria: Production of energy (both in plant and animal cells)
- Chloroplasts: Photosynthesis (only in plants)
- Vacuole: Storage of water and minerals in plant cells (only in plants)
- Cell membrane: Controls the entry and exit of materials into and out of the cell (all cells)
- Nucleus: Storage of genetic material and controlling all activities of the cell (both in plant and animals)
- Cell wall: Provides strength for the cell (both in bacteria and plant cells)
- Cytoplasm: Site for chemical reactions in the cell (all cells)
- Ribosomes: Synthesis of proteins (all cells)
Specialized Cells
- Specialized cells are cells that are adapted to perform a specific function.
Examples of Animal Specialized Cells
- Red blood cell: Transports oxygen from the lungs to the body and carbon dioxide back to the lungs.
- Nerve cell: Sends electrical signals that help you feel sensations and move your muscles.
- White blood cell: Fights infection and disease as part of the immune system.
- Ciliated cell: Helps move fluids and particles in the respiratory system.
- Root hair cell: Absorbs water from the soil.
- Xylem cell: Transports water and minerals through the stem to the leaves.
Levels of Organization
- Cells: Basic unit of life (e.g., ciliated cell, white blood cell, nerve cell, muscle cell, xylem cell)
- Tissue: Group of similar cells linked together that perform the same function (e.g., muscle tissue, nervous tissue, connective tissue)
- Organ: Group of tissues that perform a specific function (e.g., stomach, heart, skin, kidney, liver, spleen, intestines, gall bladder, pancreas, leaves, stem, roots, fruits, flowers)
- Organ system: Group of organs that work together to fulfill a specific purpose (e.g., nervous system, respiratory system, digestive system, circulatory system, shoot organ system, root organ system)
- Organism: A living thing that can function on its own (e.g., humans, plants, fungi, bacteria, archaea)
Classification
- Classification is a method of grouping living organisms based on their similarities.
Binomial Nomenclature
- Binomial Nomenclature is a system of naming living organisms using a two-word name, proposed by Carl Linnaeus.
- The first word represents the genus, and the second word represents the species.
Kingdom
-
Animalia:
- Have a nervous system.
- Can move from one place to another.
- Are heterotrophic (feed on other organisms).
- Multicellular with many organs.
- Examples: cow, tiger, monkey, butterfly, dog, platypus, whale, cat, eagle, racoon, koala.
-
Plantae:
- Autotrophic (make their own food through photosynthesis).
- Multicellular with organs like leaves, stems, and roots.
- Examples: mango tree, tulips, cactus, sunflower, daisies, lavender, lily of the valley, orchids, palm trees, rose bush, chrysanthemum, guarana, kelp.
-
Fungi:
- Heterotrophic.
- Produce/release spores.
- Feed on dead decaying matter.
- Examples: mushrooms, yeast, bracket fungi, toadstools, moulds.
-
Protoctista:
- Some have chlorophyll and can make their own food (autotrophic), while some are heterotrophic.
- Unicellular and multicellular organisms.
- Examples: Euglena, algae, amoeba, plasmodium.
-
Monera/Prokaryote:
- Unicellular.
- Extremely small.
- Prokaryotic cells (lack a nucleus).
- Some cause diseases, not all.
- Examples: All bacteria.
