This document classifies and describes different types of plants. It divides plants into two main groups: flowering plants and non-flowering plants. Flowering plants are further divided into angiosperms, which produce fruits containing seeds, and gymnosperms, which have small flowers and develop seeds in cones instead of fruits. Non-flowering plants include ferns, which reproduce via spores and have fronds but no flowers or fruits, and mosses, which have simple stems, leaves, and reproduce via spores inside capsules. The document also describes key parts of plants like leaves, roots, stems, and the process of photosynthesis by which plants produce their own food.

FLOWERING PLANTS NON-
FLOWERING PLANTS
ANGIOSPERMS GYMNOSPERMS FERNS
MOSSES

4. FLOWERING PLANTS
ARE DIVIDED IN TWO GROUPS
ANGIOSPERMS
IN ANGIOSPERMS POLLINATED FLOWERS
PRODUCE FRUITS WITH SEEDS INSIDES.
GYMNOSPERMS
GYMNOSPERMS HAVE SMALL FLOWERS.
THEY DON’T PRODUCES FRUITS, THEIR
SEEDS DEVELOP IN CONES.

5. NON-FLOWERING PLANTS
DON’T PRODUCE SEEDS
FERNS
THEY HAVE ROOTS AND STRONG STEM WICH
GROW UNDER THE GROUND.
THEY HAVE LARGE LEAVES CALLED FRONDS.
THEY PRODUCE SPORES INSIDE SORI ON THE
UNDERSIDE OF FRONDS.
MOSSES
HAVE VERY SIMPLE STEMS AND LEAVES.
THEIR ROOTS ARE CALLED RHIZOIDS.
THEY PRODUCE SPORES INSIDES CAPSULES.

6. LEAVES
THEY CONTAIN CHLOROPHYLL.
MOST LEAVES HAVE TWO
PARTS: THE PETIOLE AND
THE BLADE. VEINS IN THE
BLADE SUPPORT THE LEAF
AND CARRY WATER AND
MINERALS. ON THE
UNDERSIDE OF THE BLADE,
THERE ARE TINY HOLES,
CALLED STOMATA, WHERE
THE GAS EXCHANGE TAKES
PLACE.
ROOTS
THEY HOLD PART THE PLANT IN
THE GROUND. THEY
ABSORB WATER AND
MINERALS FROM THE
GROUND THROUGH THE
ROOT HAIR.
PARTS OF PLANTS

7. FLOWER
STEM
IT HOLDS UP THE OTHERS
PARTS OF THE PLANT. IT ALSO
TRANSPORTS WATER AND
MINERALS TO THE LEAVES FOR
PHOTOSYNTESIS.

8. PLANT NUTRICION
PLANTS MAKE THEIR ONW FOOD THROUGH THE PROCESS CALLED
PHOTOSYNTESIS
1. THE ROOTS ABSORB WATER AND MINERALS FROM THE SOIL.
2. XILEM CELLS TRANSPORT THIS MIXTURE OF WATER AND
MINERALS , CALLED RAW SAP, THROUGH THE STEM TO THE
LEAVES.
3. LEAVES ABSORB CARBON DIOXIDE THROUGHTHEIR STOMATA. IN
THE CHLOROPLAST, CHLOROPHYLL COLLECTS SOLAR ENERGY
TO TRANSFORM WATER, MINERALS AND CARBON DIOXIDE INTO
GLUCOUSE AND OXYGEN.
4. PHOEM CELLS CARRY THE GLUCOUSE, THE PLANTS FOOD
THROUGH THE STEM TO ALL THE PARTS OF THE PLANT.
PHOTOSYN TESIS IS VERY IMPORTANT BECAUSE:
1. IT GIVES US OXYGEN TO BREATHE
2. IT CONSUMES CARBON DIOXIDE
