Protective components of foods are
-
Minerals and vitamins
-
Minerals, carbohydrate and proteins
-
Minerals, carbohydrate and fats
-
Vitamins, water and carbohydrate
Protective components of foods are minerals and vitamins. Vegetables like spinach, cabbage, brinjal, beans, and fruits are called protective foods. These components protect us from diseases. Hence, they are called protective components of food. Carbohydrates and fats are the energy components of the food. Proteins are bodybuilding components of the food.
The nutrient synthesized by plants through photosynthesis is
-
Proteins
-
Carbohydrates
-
Hormones
-
Fats
The nutrient synthesized by plants through photosynthesis is carbohydrates. Plants are autotrophs and they synthesize their own food by the process of photosynthesis. During photosynthesis, they convert carbon dioxide and water in presence of sunlight and chlorophyll to produce carbohydrates (glucose) and oxygen.
___________ is an inorganic nutrient.
-
Nitrogen
-
Urea
-
Glucose
-
Glycine
An inorganic nutrient is essentially any compound or element that is not carbon-based, but is otherwise necessary to maintain health and optimum growth of a plant, animal, or human. Nitrogen is an inorganic nutrient that is later converted to organic forms like nitrite, nitrate or ammonia.
The most important component formed by plants which is useful for the growth is
-
Carbohydrates
-
Proteins
-
Fats
-
None of the above
Proteins are major element required in the growth of the plant cells. In plants, all the 20 amino acids should be formed in the plant body because they cannot take them up fro any other source. Proteins are essential as they are the basic constituents of enzymes, cell membrane, and transport systems.
Carbohydrate is made up of all except
-
Carbon
-
Nitrogen
-
Oxygen
-
Hydrogen
Carbohydrates, as the name suggests, are the hydrates of carbon and thus are made up of molecules of hydrogen, oxygen and carbon.
Stomata do not occur in ________.
-
Algae
-
Liverworts
-
Mosses
-
Ferns.
Sea Lettuce is _____________.
-
Laminaria
-
Chlorella
-
Sargassum
-
Alva
The most important character which is used in classifying different algae is
-
Cell wall structure
-
Habit
-
Types of pigments
-
None of the above
The seven divisions of organisms that are considered within the algae are the Euglenophyta, Chrysophyta, Pyrrophyta, Chlorophyta, Rhodophyta, Paeophyta, and Xanthophyta. These divisions are separated on the basis of various features including their morphology and the biochemistry of their pigments, cell walls, and energy-storage compounds. The colors of these various algae types differ according to their particular mixtures of photosynthetic pigments, which typically include a combination of one or more chlorophylls and various accessory pigments.
Slimy, green patches in ponds or in stagnant water is
-
Fungi
-
Bryophytes
-
Bacteria
-
Algae
One of the simplest multicellular organisms is algae. They are seen growing in the freshwater of marine habitats. They are also eukaryotic organisms. Algae can grow rapidly when exposed to stagnant waters. An adequate amount of sunlight, temperature and aquatic habitat leads to the rapid growth of slimy, green patches containing chlorophyll called algae.
Cell wall of Chlamydomonas possesses _____________.
-
Cellulose
-
Glycoproteins
-
Hemicellulose
-
Proteins only.
The cell wall of the unicellular green alga Chlamydomonas consists of glycoproteins, which also occurs in the extracellular matrix of multicellular green algae and higher plants.
