This document discusses the parts and functions of plants. It describes the root, stem, leaves, flowers, and fruits of plants and their key roles. The root anchors the plant, absorbs water and nutrients, and transports them to the stem. The stem supports the plant, stores food, and connects the roots to the leaves. The leaves perform photosynthesis to make food, exchange gases, and cause transpiration through evaporation of water. Flowers function to reproduce through their reproductive organs and provide nectar to attract insects and birds to help transfer pollen. Fruits protect and aid the dispersal of seeds while also storing food.

1. A group of organism that do not depend
on others for nourishment
It is the only living things that can make
their own food.

2. PARTS OF A PLANT

3. ROOTS
FUNCTIONS:
- ANCHORING OF THE PLANT TO THE SOIL.
- ABSORPTION OF WATER AND NUTRIENTS FROM THE
SOIL.
- CONDUCTION OF ABSORBED WATER AND NUTRIENTS
TO STEM.

4. STEMS
FUNCTIONS:
- CONNECTS THE ROOTS TO THE LEAVES
- PROVIDES SUPPORT, STORES FOOD
- HOLDS THE LEAVES, FLOWERS, AND BUDS

5. LEAF
FUNCTIONS:
- MANUFACTURE OF FOOD (PHOTOSYNTHESIS)
- INTERCHANGE OF GASES BETWEEN THE ATMOSPHERE
AND THE PLANT BODY
- EVAPORATION OF WATER (TRANSPIRATION)

6. FLOWER
FUNCTIONS:
- REPRODUCTION ; THE REPRODUCTIVE ORGAN
OF A FLOWER
- PROVIDE NECTAR TO CERTAIN BIRDS AND
INSECTS, WHICH IN TURN HELP IN THE TRANSFER
OF POLLEN FROM ONE FLOWER TO THE OTHER

7. Parts of a Flower
Essential parts - reproduction
(stamen & pistil)
Accessory parts – helps to
achieve reproduction
(sepals, petals, receptacle &
peduncle)

8. Essential part

9. Essential part

10. Accessory part
Receptacle is the enlarged end of a
stalk to which the flower is attached
Peduncle – stalk of the flower
Receptacle

11. FRUIT FUNCTIONS:
- IT PROTECTS THE SEED AGAINST INJURY
AND OTHER UNFAVORABLE CLIMATIC
CONDITIONS
- IT HELPS IN THE DISPERSAL OF SEEDS
- IT STORES FOOD MATERIALS
- FRUITS ARE THE EDIBLE PART OF A PLANT
