Plants, transport systems

plants how they get nureiwnts

Roots (+ root hair cells) = needed to absorb water and nutrients

• Stomata in leaves + stems are the site of gas exchange

plants how they breathe

Plants lack respiratory system

• oxygen and carbon dioxide move through diffusion

• Diff - movement of susbtance high con - low con

•Inside leaves, CO₂ is high, so this gas exits ❌ blue

•Outside leaves, O₂ is high, so this gas enters ❌blue

Plants waste

• Plants need prevent the build up of wastes by removing them via stoma( eg oxgyen + carbon)( X blue)

Stomata on leaves + stems = pores formed by two ‘guard cells’

Vascular system

• transport network of tissues that moves water, minerals, + sugars thruout plant

• composed of tissue = xylem + phloem

• trasnport within sap(like blood) x blue

eg question -

. Why is the vascular system important for plant survival?

It delivers water, minerals, and food to all parts of the plant, allowing it to grow, make food, and stay alive.

Xylem

•Transport water and minerals from the roots to the leaves (one direction only)

Phloem

Phloem: Transport sugars + nutrients around plant ( both directions)

Role stomata play in transpiratipon x blue but good to kno

Open + close to allow water + oxyg be released, + carb dioxide to be taken up by plant 4 photosynthesis

x blue but good to know

the process - a plant take in water thr roots, uses what it needs,+ lets extra water turn into a gas (water vapor) + escape out thru stomata in its leaves
