Transpiration: Other than photosynthesis, leaves play a crucial role in the removal of excess of water from plants through tiny pores called stomata. Which of the following statements describe photosynthesis? They are partial heterotrophs as they eat insects for obtaining nitrogen. Answer: Animals like tiger, wolf, lion and leopard are carnivores and do not eat plants. Question: Lichen is a saprophytic plant. The process by which green plants make their own food (like glucose) from carbon dioxide and water by using sunlight energy (in the presence of chlorophyll) is called photosynthesis. The function of carbohydrates in plants and animals is that they are a source of fuel for growth. These bacteria take nitrogen gas from the atmosphere and convert it into water soluble nitrogen compounds making it available to the leguminous plants for their growth. All green plants and a few other autotrophic organisms utilize photosynthesis to synthesize nutrients by using carbon dioxide, water and sunlight. Answer: False, fungi are not green and they are not classified as plants. Sources of raw materials required for photosynthesis: Thus, photosynthesis can be represented by the following equation. Plants need light energy, CO2, and H2O to prepare food. Their roots take up water and minerals from the ground and their leaves absorb a gas called carbon dioxide (CO2) from the air. Fungus are also useful in that they produce many antibiotics which can cure different types of infections like penicillin. This is because, leaves synthesize food by the process of photosynthesis. (T/F), Carbon dioxide is released during photosynthesis. They are saprophytic organisms which derive nutrition from dead and decaying matter. Animals and most other organisms take in ready made food prepared by the plants and are called heterotrophs nutrients. This process is called photosynthesis. (The leaves owe their characteristic green color to the presence of this green pigment in them.) 10. This continuous usage depletes the concentration of mineral in soil. Answer: Insectivorous plants grow in soil which lack nitrogen, therefore they eat insects to fulfill their need of nitrogen. Lichen is a saprophytic plant. In return, leguminous plants provide food and shelter to the bacteria as Rhizobium cannot prepare its food. Water is taken in from the roots of the plant and is transported to the leaves. Answer: In sunflower seeds, glucose is stored in the form of oils (fats). Examples of saprotrophs are fungi and some bacteria. 1 See answer gauravshingye is waiting for your help.

A parasitic plant with yellow, slender and tubular stem. This indicates the absence of starch. Yes, the benefit of leguminous plant is the re-enrichment of soil minerals. Green plants are included in this group. Show with the help of a sketch that plants are the ultimate source of food. The mode of nutrition in which organisms make food themselves from simple substances is called autotrophic nutrients. (T/F), Solar energy is converted into chemical energy during photosynthesis. (c) In photosynthesis solar energy is absorbed by the pigment called chlorophyll. Answer: Leaves contain chlorophyll which is essential for food preparation and is absent in other parts of plant. (T/F), The product of photosynthesis is not a protein. They are saprophytic organisms which derive nutrition from dead and decaying matter. They prepare food through photosynthesis and transport it to the underground part for storage. Carbon dioxide is a vital ingredient in the process of photosynthesis. Answer: Water and minerals are transported to the leaves by the vessels which run like pipes throughout the root, stem, branches and the leaves. The three major functions that are basic to plant growth and development are: Usually, the process of photosynthesis takes place in two stages, i.e. Answer: Our body does not contain chlorophyll for absorbing solar energy which is necessary for preparing food using air, water etc. Plants make their own food by a process called Photosynthesis. They need simple things like carbon dioxide and water and can make complex things like sugar, starch, fat, and proteins. These vessels are xylem and phloem, forming a continuous path or passage for the nutrients to make them reach the leaf. Plants are called autotrophs because they can use energy from light to synthesize, or make, their own food source. Answer: Yes, these animals/insects are parasites as they harm the hosts while they suck blood. Answer: Cuscuta derives its nutrition using an association where it deprives its host of all valuable nutrients and absorbs them itself. These plants also produce oxygen for other organisms … Carbon dioxide molecules and water molecules are used as raw materials to synthesize carbohydrate molecules. Which of the following statements describe photosynthesis? The end products of … Answer: False, food is necessary for all the living organisms as all of them grow and require maintenance from time to time. The stored glucose is used by the plant to carry out various cell activities such as growth, reproduction, and respiration to mention a few. They, thus have a symbiotic relationship. Answer: Guard cells help in controlling the opening and closing of stomata for gaseous exchange. Important Questions For Board Exam 2020 O.C.M.

Under normal air-quality circumstances, the concentration of carbon dioxide ranges from 300 to 400 ppm. The leaves of green plants have microscopic openings on leaf surfaces (generally on the underside) known as stomata. all animals, fungi and non-green plants. (b) The food synthesised by the plants is stored as starch. Heterotrophs are those which are dependent on other plants and animals for their food. These include: The amount of light reaching the plant’s leaf has a significant impact on the rate by which it creates food. Q: How do green plants manufacture their own food? Plants hv 20 types of amino acids. This means that they can survive without animals! In photosynthesis solar energy is captured by the pigment called ___________. We see small, fluffy, umbrella-like plants growing on rotting wood during the rainy season These are a kind of fungus called mushrooms. Water and Minerals are transported to the leaves by the vessels which run like pipes throughout the route, the stem, the branches and the leaves. Euglena is an exception. In this way the plants fulfil their requirements o f nitrogen along with the other constituents. During respiration, plants burn sugars to build living cells, giving off carbon dioxide and water.”. Anything that Photosynthesises is creating its own food in a way by taking in water and light to synthesise sugars. What are noted benefits of this process? All activities such as playing, running, walking, studying etc. Plants are self-sufficient. Answer: True, because photosynthesis is important for the existence of life on the earth. Chlorophyll can make food the plant can use from carbon dioxide, water, nutrients, and energy from sunlight. Without producers, consumers like humans, would not have the food or energy they need to survive. The hydrogen ions obtained are combined with carbon dioxide absorbed from the air in order to form glucose (a simple sugar molecule). A few types of plants lack chlorophyll in their cells and are incapable of carrying out photosynthesis. As such, green synthesis is regarded as an important tool to reduce the destructive effects associated with the traditional … Question 6: Why green leaves are thin and broad ?

Harish is sincere, curious and knowledgeable with a keen sense of applying it where necessary. 1,670 Views. Examples of plants that don’t use photosynthesis to make their own food are ghost plant (Monotropa uniflora) and Beechdrops (Epifagus virginiana), both native to North America. The energy is used to … During photosynthesis, plants trap light energy with their leaves.
The non-green plants called fungi derive their food from dead and decaying organic matter, so fungi are saprophytes. All the plants/crops grown in soil use the minerals present in soil for their own use. they prepare their own food. Answer: All living organisms require food to survive. This can decrease absorption of carbon dioxide required for the synthesis of glucose. Answer: Plants such as gram, pulses and beans are leguminous. No, not all plants are capable of making their own food/autotrophs. Answer: Roots of pulses (leguminous plants) have a symbiotic association with a bacterium called Rhizobium. In materials science, “green” synthesis has gained extensive attention as a reliable, sustainable, and eco-friendly protocol for synthesizing a wide range of materials/nanomaterials including metal/metal oxides nanomaterials, hybrid materials, and bioinspired materials. Plants that do not have chlorophyll are called non-green plants. Answer: Parasites they are those organisms which grow on other plants or animals for their food, e.g. Photosynthesis is important process as it is provides food to all living organisms and maintains CO2 â O2 balance of nature. Answer:Â Yes, the fungi reproduces by spores which are generally present in the air and grow on any article that are left in hot and humid weather for a long time. Rhizobium bacteria live in the root nodules of leguminous plants. Therefore, if the concentration of CO2 is high, the rate of photosynthesis also increases proportionally. Plants and their Nutrition Requirements. These plants are “Holoparasites”, and obtain their food by attaching themselves to other plants or fungi. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds. For many plants, the optimal temperature range for photosynthesis is between 75°F – 95°F (about 25°C – 35°C). In a process known as respiration, organelles inside plant cells called mitochondria use the stored chemical energy in the carbohydrate molecules to build new plant cells.
