Bio Terms

Must be grown from seed each year

• two year life cycle
• (carrots)

plants regrow or reflower each year

Embryonic shoots

Where leaves meet the stems

Tip of the stems and branches where new growth takes place

Xylem, Phloem and Epidermal system

Water and nutrients transported from the roots

Transports carbohydrates from areas of production to the rest of the leaves (photosynthesis; primarily leaves).

• protects against water loss.
• produce guard cells, forming stomata

• General cell type, most numerous in young plants.
• Functions as living cells
• -photosynthetic
• -used for storage

Support cells

• destined to form a terminal structure.
• -leaf and flower
• -programmed, ends with differentiation into non dividing cell types

• -in meristems
• -undifferentiated cells persist while new roots and shoots grow
• -contain potential to develop into all root and shoot structures

• dicot characteristics
• -depends on function of vascular cambium and cork cambium, which are not present in monocots.
• -cork surrounds stem and roots
• -water proofing
