FC: Plants By: Kieli #9
1: PLANTS | -Keep all animals alive. -Take in CO2, let out O2. -Photosynthesis means, ‘food from sunlight’. -Desert plants survive by storing food in all parts of the plant -Some plants contain natural chemicals to cure diseases. -When chlorophyll leaves the leaves, they change colors. -Plants make fruit so that animals can take the seeds to another place. -There are 3 types of plants that don’t need roots to grow. Mosses, Hornworts, and Liverworts. -Plants store different sugars. -Burned sugar makes CO2, which plants use for photosynthesis.
2: Vascular Plants: Vascular plants are plants that have leaves and stems that are tubular. These tube-like structures allow water and nutrients to move through the plant. | Roots: Absorbs water and nutrients , keeps the plant in the soil. Stem: Transports water and sugar to other parts of the plant, also helps support the plant. Leaves: Where photosynthesis occurs. Examples: -Ferns (spores) -Flowering plants (angiosperm: seeds that have a cover/hull) -Conifers (gymnosperm: seeds that are protected inside a cone, naked seeds)
3: Xylem and Phloem | Xylem: This is a tissue group in a vascular plant that is a group of cells working together as a system that transports water and nutrients from the roots to the leaves. This is a major water conducting system. It takes things from the bottom of the plant, up. Phloem: This vascular tissue transports sugar down. It takes things from the top of the plant, down, and out to the leaves.
4: Non-Vascular Plants | A non-vascular plant is a simple plant that grows and sits low to the ground. They live in damp swampy areas, and they absorb water from the air. Non-vascular plants don't have roots, stems, and leaves as we know them. They have similar systems to them, but they don't have stems, roots, and leaves. There are 3 types: Mosses, Liverwort, and Hornwort.
5: Photosynthesis | Photo=light Synthesis=putting together Photosynthesis is done by all of the following: water, xylem, phloem, stomata, oxygen, and sugar. Photosynthesis: Is the process where the cells of green plants use the energy of the sun’s light to synthesize, or create their own food. Chlorophyll is found inside of a cell called a chloroplast. This is where photosynthesis takes place. Sugars and other carbohydrates are produced and oxygen is released. Steps of photosynthesis: 1. Plants trap the sun’s light energy and use that energy to break down water into oxygen and hydrogen. Some oxygen is used, but most is released. 2. Carbon dioxide taken in by the plant's leaves, and is combined with the oxygen and hydrogen to form glucose. 3. More reactions combine the glucose molecules into chains and form more complex carbohydrates.
6: Photosynthesis | Formula for Photosynthesis: 6 CO2 + 6 H2O->C6H12O6 + 6 O2 Carbon dioxide + Water + Light energy->Glucose + Oxygen Photosynthesis needs H2O, and CO2 to happen. They also need chlorophyll in chloroplasts, plants, sunlight, a water source, Xylem+Phloem, roots, stems, and leaves. Formula for Glucose: C6H12O6+6O2
