Study Notes
Cell Types and Structures
- Prokaryotic cells lack a nucleus and are generally smaller and simpler in structure than eukaryotic cells.
- Eukaryotic cells contain a nucleus and various organelles, including mitochondria and chloroplasts, contributing to their complexity.
- Cells that have a cell wall containing peptidoglycan are primarily prokaryotic, specifically bacteria.
Organelles and Functions
- Mitochondria and chloroplasts are present in eukaryotic cells, functioning in energy production and photosynthesis, respectively.
- Flagella are long, whip-like structures that enable movement in certain cells, such as sperm cells and some bacteria.
Botany and Plant Studies
- Botany refers to the science of plant life, encompassing the study of various plant groups.
- Traditionally, botany includes the study of flowering plants, ferns, mosses, fungi, and algae.
- Botanists study approximately 390,000 species of land plants.
- A scientist who specializes in botany is called a botanist.
