Answer:
1. The word photosynthesis can be separated to make two smaller words: “photo” which means light. “synthesis” which means putting together.
2. Dodder, Cuscuta species, is a parasitic annual plant that infests many crops, ornamentals, native plants, and weeds. More than 150 species occur worldwide, although dodder is most prevalent in the Americas.
3. A portion of the plants are somewhat heterotrophs - They may expend effectively arranged natural mixes yet, also, can make their own chemicals. Such plants are the flesh-eating plants like Venus flytrap, Nepenthes and others.
4. A saprophyte or a saprotroph is an organism which gets its energy and nutrition from dead and decaying organic matter like the decaying pieces of plants or animals.
5. Two kinds of nitrogen-fixing bacteria are recognized. The first kind, the free-living (nonsymbiotic) bacteria, includes the cyanobacteria (or blue-green algae) Anabaena and Nostoc and genera such as Azotobacter, Beijerinckia, and Clostridium.
6. an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.
1. Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green. Plants that use photosynthesis to make their own food are called autotrophs
2. The role of chlorophyll in photosynthesis is vital. Chlorophyll, which resides in the chloroplasts of plants, is the green pigment that is necessary in order for plants to convert carbon dioxide and water, using sunlight, into oxygen and glucose.
3. Plants get the carbon dioxide they need from the air through their leaves. It moves by diffusion through small holes in the underside of the leaf called stomata . ... These let carbon dioxide reach the other cells in the leaf, and also let the oxygen produced in photosynthesis leave the leaf easily.
