Modes of Nutrition

We all KNOW that the plants can make their own food through the process of photosynthesis, however, animals and human beings cannot make food for themselves. They obtain food from plants and other animals that feed on plants. Thus, it is seen that human beings and animals depend on plants for their food – somewhere directly or indirectly.

GREEN plants are autotrophic and synthesize or make their own food by the process of photosynthesis. They do this with the help of carbon dioxide and WATER in the presence of sunlight. Photosynthesis is the process by which the green plants make their own food ( like glucose ) from carbon dioxide and water by using sunlight energy in the presence of chlorophyll.

On the basis of their modes of nutrition, all the organisms are divided into two main groups – autotrophs and HETEROTROPHS. Their corresponding modes of nutrition are known as the autotrophic and heterotrophic mode of nutrition.

Autotrophs (or Autotrophic Modes of Nutrition)

autotrophic modes of nutrition

Those organisms that can make food themselves from simple substances like carbon dioxide and water are called autotrophs. Their mode of nutrition is referred to as autotrophic. They do this by the process of photosynthesis.

All the green plants are called autotrophs. This is due to the fact that the green plants make their own food from very simple substances like carbon dioxide and water that is present in the surroundings. They do this by the process of photosynthesis.

We can also say that the green plants have an autotrophic mode of nutrition. These green plants contain a green pigment called chlorophyll which further helps in making food by absorbing energy received from the sunlight. Majorly the green plants synthesize their own food – not only for themselves but also for the non-green plants, animals as well as human being.

Heterotrophs (or Heterotrophic Modes of Nutrition)

Heterotrophs (or Heterotrophic Modes of Nutrition)heterotrophic modes of nutrition

Heterotrophs are referred to those organisms which cannot prepare their own food. They are dependent on green plants or animals for their food. Their mode of nutrition is known as the heterotrophic mode of nutrition. All the non-green plants and animals, inclusive of human beings, are called heterotrophs.

The non-green plants lack chlorophyll which is necessary to carry out the process of food referred to as photosynthesis. Therefore, they depend on other organisms i.e. plants and animals in order to obtain food.

The non-green plants, for example. Fungi, YEAST, mushroom, bread mold, are called heterotrophs. They have a heterotrophic mode of nutrition. Therefore, all animals like dogs, cats, cow, buffalo, lion, tiger, deer as well as human beings are called heterotrophs. Their mode of nutrition called ‘ heterotrophic mode of nutrition ‘.

WIND AND INSECT POLLINATED FLOWERS

Explanation:

Wind pollinated flowersInsect pollinated flowersPollinating AgentThe pollinating agent is wind.The pollinating agents are an insect.Morphological features of a FlowerThe wind-pollinated flowers comprise light coloured petals, without a pleasant strong smell.The insect-pollinated flowers comprise brightly coloured petals with a pleasant strong smell.Pollen GrainsIn wind-pollinated flowers, the produced pollen GRAINS are smaller and lighter in weight, which can be carried by the wind easily.In insect-pollinated flowers, the produced pollen grains are larger in size, sticky and spiny which helps the insect to carry the pollen grains.StigmaStigma is feathery or sticky and found hanging out of petals.Stigma is small and is situated deep inside the petals.StamensThe STAMENS are long and VISIBLE out of petals.Stamens MAY be small and hidden inside petals.AntherThe anthers are often seen being supported outside the flowerThe anthers are found deep inside the flower.FilamentsThe FILAMENTS found in these flowers are slender and long.The filaments found in these flowers are strong and short.Production of NectarThese flowers do not produce nectars.These flowers produce a lot of nectars.WastagesThere is a lot of wastage as more number of pollen grains are produced.There is no wastage as less number of pollen grains are produced.Type of FlowersPlants bear only unisexual flowers.Plants bear bisexual flowers.

Answer:

Importance of water in seed germination

Water is required for germination. ... The uptake of water by seeds is called IMBIBITION, which LEADS to the swelling and the breaking of the seed coat.
