Study Notes
Cambium Function
- Primary function is to facilitate secondary growth by producing new layers of xylem and phloem.
- Acts as a lateral meristem, adding girth to the stem through cell division.
Structural Support
- Collenchyma and sclerenchyma tissues provide structural support in a dicot stem.
- Collenchyma offers flexible support, while sclerenchyma provides rigid strength.
Vascular Arrangement
- Vascular bundles are usually arranged in a circular pattern in a dicot stem.
- Each bundle contains xylem (toward the interior) and phloem (toward the exterior), separated by cambium.
Protective Layer
- The outermost layer, known as the epidermis, acts as a protective covering in a dicot stem.
- Can be covered by a waxy cuticle to reduce water loss and shield against pathogens.
Nutrient Transport
- Phloem tissue is primarily involved in the transport of organic nutrients, such as carbohydrates.
- Sieve tubes in the phloem facilitate the movement of sugars produced during photosynthesis.
