Study Notes
Plant Structure and Function Review
- Types of plant tissues include meristematic, dermal, and vascular tissues.
- Meristematic tissues are responsible for cell division and growth.
- Dermal tissues protect the plant from the environment.
- Vascular tissues transport water and nutrients. Xylem and phloem are the two types.
- Xylem transports water and minerals from roots to other parts of the plant.
- Phloem transports sugars and other nutrients from leaves to other parts of the plant.
- Ground tissue is located between dermal and vascular tissues and supports plant growth and function.
- Root hairs increase surface area for water and mineral uptake.
- Root cap protects the root tip.
Stem Structure and Function
- Vascular tissue in stems connects roots and leaves.
- Stems provide support for the plant's parts.
- Some stems store nutrients.
- Xylem transports water and minerals, phloem transports sugars.
Leaf Structure and Function
- Cuticle is a waxy layer protecting the leaf from water loss.
- Mesophyll tissue, made of palisade (photosynthesis) and spongy layer (gas exchange) contains chloroplasts for photosynthesis.
- Guard cells control the opening and closing of stomata, which regulate gas exchange. Stomata are openings on leaves that allow for gas exchange and transpiration.
- Roots, stems, and leaves function in supporting and transporting water and nutrients.
Plant Transport
- Transpiration is the evaporation of water from a plant's leaves. It drives water movement upward.
- Water moves from roots to shoots through xylem.
- Osmosis and active transport facilitate water uptake.
- Cohesion and adhesion helps water move through xylem vessels and transpiration.
- Osmosis is the movement of water from a high concentration to a low concentration across semi-permeable membranes.
- Diffusion is the movement of molecules from an area of high concentration to an area of low concentration, until they are evenly distributed.
Plant Growth
- Primary growth involves growth of apical meristems and first-year growth of lateral meristems.
- Secondary growth happens from lateral meristems and occurs after the first year
- Tropisms are plant responses to environmental stimuli, including phototropism (light), gravitropism (gravity), and thigmotropism (touch).
Plant Adaptations
- Adaptations allow plants to survive in specific environments
- Some species have tropisms or specific features.
Plant Classification
- Vascular plants have a vascular system (xylem and phloem).
- Nonvascular plants rely on diffusion and osmosis for transport.
Plant Tissues Review
- Diagrams may be referenced to clarify different tissue arrangement and locations
