Study Notes
Cell Types and Classification
- Yeast cells and photosynthetic plant cells are classified as eukaryotic due to the presence of a nucleus and membrane-bound organelles.
- Elodea, a type of aquatic plant, also categorizes as eukaryotic for similar reasons.
- Streptococcus, a bacterial organism, is prokaryotic; all bacteria belong to this classification.
- Prokaryotic cells, like Streptococcus, lack a nucleus and membrane-bound organelles.
Organelles and Function
- Organelles are specialized membrane-bound compartments within eukaryotic cells that perform distinct functions essential for cellular operation.
Examples of Organisms by Kingdom
- Archaebacteria (e.g., Joostella marina) are prokaryotic organisms.
- Eubacteria (e.g., Bacillus anthracis) are also classified as prokaryotic.
- Protists, such as Paramecium, are examples of eukaryotic organisms.
- Fungi, represented by Pilobolus, are classified as eukaryotic.
- Plantae, such as the venus flytrap, and Animalia, like the three-toed sloth, are both eukaryotic domains.
Nutrition and Cell Structure
- Heterotrophs are organisms that derive energy by consuming other living things, unlike autotrophs which produce their own food.
- Unicellular organisms consist of a single cell, while multicellular organisms are composed of multiple cells.
Reproductive Strategies
- Sexual reproduction results in offspring that possess genetic material from both parents, contributing to genetic diversity.
- Asexual reproduction produces two genetically identical cells, ensuring uniformity of the offspring.
Kingdoms of Life
- There are six primary kingdoms: Fungi, Animalia, Plantae, Protista, Bacteria, and Archaea, which encompass all known life forms.
Prokaryotic Cell Characteristics
- Prokaryotic cells are typically unicellular and have a simpler structure compared to eukaryotic cells, leading to the classification as primitive.
Genetic Material Location
- In eukaryotic cells, DNA is housed within the nucleus, separating it from the cytoplasm and allowing for greater complexity in gene expression and regulation.
