Plants need water, minerals, carbon dioxide, sunlight, and chlorophyll to grow through the process of photosynthesis. Roots absorb water and minerals from the soil which travel through the xylem vessels to the leaves. Leaves take in carbon dioxide through stomata and use the chlorophyll and sunlight to transform the raw sap and carbon dioxide into glucose. The glucose is then transported throughout the plant via the phloem vessels to provide nutrients and energy for growth and survival. At night when photosynthesis stops, plants release carbon dioxide.

6. ROOTS

7. They hold the plant in the ground.
They absorb water and minerals from the ground.
There are two types of roots:
TAPROOTS
FIBROUS ROOTS
ROOTS

11. STEM
It supports the plant (the leaves, the flowers and the fruit).
It distributes the water, and minerals and the food through
the plant.
There are two types of stems:
WOODY STEMS
HERBACEOUS STEMS

12. WOODY STEM
 It’s hard and rigid.
They are called TRUNKS.

13.  It’s soft and flexible

14. LEAVES

15. LEAVES
They grow from the stem.
They contain the chlorophyll.

16. THEY HAVE 2 PARTS:

17. PETIOLE : It joins the blade to the stem.

18. BLADE : It’s the flat part of the leaf.
 It has VEINS.
 They support the leaf and carry water and minerals.
 It has STOMA (small pores)

24. PHOTOSYNTHESIS

25. PHOTOSYNTHESIS
Plants make their own food, through
a process called PHOTOSYNTHESIS.
WATER + MINERALS + CARBON DIOXIDE + SUNLIGHT + CHLOROPHYLL =
GLUCOSE AND OXYGEN

26. 1. The roots absorb water and minerals from the soil. This is
called the raw sap. The xylem vessels transport it from the
roots to the leaves.
WATER + MINERALS = XYLEM SAP

27. 2. Leaves absorb carbon dioxide through the stomata.
carbon
dioxide

28. 3. The chlorophyll traps Sunlight.
This energy from the Sun, transforms the raw sap and
carbon dioxide into glucose.
The plant expels excess oxygen through stomata.
RAW SAP + CARBON DIOXIDE = GLUCOSE

29. 4. This glucose is transported in the elaborated sap to
the rest of the plant through the phloem vessels.
PHLOEM SAP = GLUCOSE + OXYGEN

31. At night, when photosynthesis stops,
plants no longer expel oxygen.
During this time they just release
carbon dioxide.
