Science- plant organs

Stem : 

• The stem is the organ which holds the leaves upright in the air and facing the light.
• It carries water and minerals to the leves, and the food around the plant.
• The stem is therefore really important for nutrition, excretion and growth.

Flower :

• The flower contains the organs of plant sexual reproduction.
• It attracts insects needed to cary the pollen between plants to allow pollination.
• Its therefore really important for reproduction

Leaf:

• The leaves are the organs of photosyntheses. They make all the food that the plant needs.
• Leaves contain chlorophyll which uses light energy to change          CO2 and water into glucose.
• They have tiny little pores which allow essential CO2 in, and waste gases out- there are no lungs.
• So leaves are really important for nutrition and excretion.

Root :

• The root is the organ which provides anchorage for the plant- so it doesn't blow away or fall over by accident.
• With it's root hairs it provides a bis surface area to help take in water and minerals from the soil- these are both essential for photosyntheses.
• The root is therefore really important for nutrition.
