Plant structures
Necessities for Life
The Vascular System of the Plant
Xylem – transport of fluid and nutrients from root system to other parts of the plants
Phloem – involved in sugar and water transport between vascular system and plant cells
Absorption of Carbon Dioxide and Release of Oxygen

Functions of Plant Structures
Stomata – pores in cuticle that allow carbon dioxide and oxygen to pass through
Guard Cells – control the opening/closing of the stomata
Cuticle – protective outer covering of the plant that helps to prevent water loss
Angiosperms
have flowers as reproductive structures
The Functions of Roots
Nutrient and Water Absorption
Anchor for the plant
Phototropism
an adaptation for photosynthesis
