Answer:
1.Answer: Our body gets energy from food by the process of respiration. During respiration,the oxygen inhaled burns the food to produce energy in the form of ATP(adenosine triphosphate). This energy is prepared and stored in the mitochondria...
2.The chloroplasts in the plants are the sites of photosynthesis. The chloroplasts in leaves contain closely packed flattened sacs, called thylakoids, arranged in piles, called granum. Thylakoids contain green pigments, called chlorophyll, which trap solar energy.
3.The chlorophyll present in leaves absorb light energy from the sun and convert into chemical energy. Glucose is the simple food which is prepared first in the process of photosynthesis. Glucose and oxygen are the final products of photosynthesis.
4.Plants absorb water from the soil by osmosis. They absorb mineral ions by active transport, against the concentration gradient. Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption.
5.The main difference between plants and fungi is how they obtain energy. Plants are autotrophs, meaning that they make their own "food" using the energy from sunlight. Fungi are heterotrophs, which means that they obtain their "food" from outside of themselves
6.Carnivorous plants are plants which get nutrients from trapping and eating animals. They are often called insectivorous plants, because they usually trap insects. Since they get some of their food from animals, carnivorous plants can grow in places where the soil is thin, or poor in nutrients.
7.SYMBIOSIS IS A RELATIONSHIP BETWEEN TWO ORGANISMS TO BENEFIT EACH OTHER. EXAMPLE-. LICHENS- THEY ARE THE COLONY OF FUNGI AND ALGAE. Gunjan Khattar answered Sep 19, 2018. Commensalism is a type of relationship where one of the organisms benefits greatly from the symbiosis.
8.“Autotrophs are organisms that prepare their own food through the process of photosynthesis, whereas heterotrophs are organisms that cannot prepare their own food and depend upon autotrophs for nutrition.”
