Study Notes
Definition of Plants
- Plants are multicellular eukaryotic organisms characterized by cell walls composed of cellulose and the presence of chloroplasts.
- Specialized reproductive organs are present, producing sperm and eggs either on the same or different plants.
Plant Life Cycles
- Unlike animals, many plants reproduce through haploid spores instead of sperm and egg fusion.
- Male and female plant forms can produce gender-specific spores, leading to distinct life stages separate from their genetic origins.
- Plant development occurs through mitosis, allowing new individuals to grow independently from their parents.
Evolutionary Context
- Plants existed for hundreds of millions of years before evolving flowers, lacking structure such as leaves and stems in their earliest forms.
- Traits defining plants include complex life cycles and unique reproductive strategies.
Photosynthesis and Nutrition
- The vast majority of plants (about 99%) photosynthesize, converting sunlight, carbon dioxide, and water into food.
- A small fraction of plant species have lost this ability and have become heterotrophic, engaging in predation (e.g., Venus flytrap).
- The Venus flytrap captures and digests insects using secreted enzymes to absorb nutrients.
Plant Requirements for Survival
- Essential conditions for plant growth include temperatures above freezing, sunlight, and access to carbon dioxide and water.
- Plants require oxygen for cellular respiration and minerals for synthesizing proteins and organic molecules.
Importance of Plants
- Plants are foundational to life on Earth, supporting ecosystems and being vital for the survival of many organisms, including humans.
