- They don't have special tubes to
carry water and nutrients
- Molses
- Antocers
- Hepatiques
- Seedles vascular plants:
- Have roots, stem and
leaves but don't make
seeds
- Tems
- Vascular plants:
- They have roots, stems,
leaves and those special
tubes for water and
nutrients too
- Gymnosperms:
- These plants are

movements in one
part of a plant
- Plant nutrition
- 1. Meaning they make their own food
substances from inorganic substances.
- 2. Water and minerals enter the plant
through tiny roots hairs.
- 3. Carbon dioxide enters the plant the stomata.
- 4. Once in the cells, water and carbon dioxide enter
chloroplasts.
- 5. The organic matter produced durning photosynthesis
become sap and is distributed to the rest of the plant for
nourishment.
- 6. The oxygen produced will be partly used by the
plant in repiration.
- 7. Plants, like all living beings , need energy for their
vital functions.
