Study Notes
Characteristics of Plants
- All plants share four common characteristics:
- They produce their own food through photosynthesis.
- They possess a protective waxy cuticle.
- Their cells have rigid cell walls for structure.
- Reproduction occurs via spores and sex cells.
Plant Cuticle
- A plant cuticle is a waxy layer that covers aerial parts of the plant, such as stems and leaves.
- The primary function of the cuticle is to prevent moisture loss, thereby keeping the plant hydrated.
Plant Cell Walls
- Cell walls provide structural support and protection, contributing to the plant's overall integrity.
Evolutionary Ancestor
- Green algae is considered the ancient ancestor of all plants, indicating a close evolutionary relationship.
Evidence Supporting Plant-Algal Connection
- Similar coloration between plants and green algae.
- Both contain chlorophyll, essential for photosynthesis.
- Similarity in cell wall composition.
- Energy storage in both forms takes place as starch.
- A common life cycle characterized by a two-part system.
Plant Groups
- Plants are categorized into two main groups:
- Non-vascular plants, lacking specialized tissues for transport.
- Vascular plants, featuring systems that efficiently deliver nutrients and water.
Non-Vascular Plants
- Non-vascular plants do not possess transporting pipes and rely on diffusion and osmosis for movement of materials.
- They are typically small in size.
- Examples include moss and liverwort.
Vascular Plants
- Vascular plants have specialized tissues that distribute water and nutrients throughout the plant.
- These tissues allow them to grow larger and more complex due to improved transport capabilities.
Vascular Plant Tissues
- The conducting tissues in vascular plants are known as vascular tissues.
Vascular Plant Categories
- Vascular plants are further divided into:
- Seed-producing plants.
- Non-seed-producing plants.
Non-Seeded Vascular Plants
- Examples of non-seeded vascular plants include ferns, horsetails, and club moss.
Seeded Vascular Plants
- Seeded vascular plants are classified into two groups:
- Angiosperms (flowering plants).
- Gymnosperms (non-flowering plants).
