- 2. PLANTS CLASSIFICATION OF PLANTS Flowering plants Non-flowering plants Angiosperms Gymnosperms Fens Mosses
- 3. Sexual reproducion. Flowers are their reproductive organs. They reproduce through seed. FLOWERING PLANTS ANGIOSPERMS Pollinated flowers produce fruits whith seeds inside. Examples: roses, cherry trees, blackberries, rice…. GYMNOSPERMS They have small flowers, they don´t produce any fruits and their seeds develop in cones. Many of them, such as pine trees, have long thin leaves alleld needles.
- 4. They do not produce seeds. They reproduce asexually using spores. NON-FLOWERING PLANTS FERNS They have roots and strong stem under the ground. Their leaves are called fronds. They produce spores inside sori on the underside of the fronds. MOSSES They have simple stems and leaves. Their roots are called rhizoids. They produce spores inside capsules.
- 5. PARTS OF PLANTS ROOTS They hold the plant in the groung. They absorb water and minerals from the ground through the roots hairs 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. FLOWER STEM It holds up the other parts of the plant. It also transports water and minerals to the leaves for photosyntesis.
- 6. Plants make their own food through the process called photosynthesis 1. The roots absorb water and minerals from the soil. 2. Xylem cells transport this mixture of water and minerals, caled raw sap, though the stem to the leaves. 3. Leaves absorb carbon dioxide though their stomata. In the cloroplasts, chlorophyll ccollets solar energy to transform water and minerals and carbon dioxide into glucose and oxygen. 4. Pholem cells carry the glucose, the plants´food though the stem to all the parts of the plant. PLANT NUTRITION
- 7. Is very important because: 1. It gives us oxygen to breathe. 2. It consumes carbon dioxide. 3. It transforms water and minerals into food. Animals can feed on plants to get energy to live. PHOTOSYNTHESIS
- 8. Plants consume oxygen and produce in too. Plants produce oxygen through the photosynthesis during the day. They produce more oxygen than they need and expel it through the stomata. At night, when photosynthesis stops, plants release carbon dioxide. PLANT RESPIRATION
