Banana and pumpkin plant has two or more edible parts. Their flowers and fruits are eaten as food.

Food: Food is a nutritious diet that organisms consume or absorb to maintain their various functions of life and development.
Edible: Such substances, which we can accept as food, which do no harm in our body, are called edible substances.
Nectar: A sugary juices secreted within flowers to encourage pollination by insects and collected by bees to make into honey.
Seeds and Sprouted Seeds
Seeds: A seed is the part of a plant which can grow into a new plant. It is a reproductive structure and having the power of germination. A seed is enclosed by a hard covering called the seed coat.
Sprouted seeds: When a seed starts growing after a certain time, we call that stage of germination. That is known as sprouted seeds.
Sprouts start as dry beans or seeds. Sprouts are seeds that have germinated and become very young plants. This germination process usually begins with the seeds being soaked water for several hours. The soaked seeds are then exposed to the right combination of temperature and moisture and once wet, they draw on their stored nutrients and begin to grow in 2 to 7 days.

What are the ingredients required for the making of brinjal curry?
For making brinjal curry we need brinjal, chilli, oil, spices and salt as an ingredient.
Do you know, how does honey produce? Discuss.
Bees collect nectar (sweet juices) from flowers, convert it into honey and store it in their hive. Flowers and their nectar may be available only for a part of the year. So, bees store this nectar for their use all through the year. When we find such a beehive, we collect the food stored by the bees as honey.

Obtaining Sprouted Seeds
Take some dry seeds of moong or chana. Put a small quantity of seeds in a container filled with water and leave this aside for a day. Next day, drain the water completely and leave the seeds in the vessel. Wrap them with a piece of wet cloth and set aside. The following day, you observe that a small white structure may have grown out of the seeds. If so, the seeds have sprouted. If not, wash the seeds in water, drain the water and leave them aside for another day, covered with a wet cloth. The next day, the seeds would be sprouted.
6th Science Chapter 1 Important Questions Set – 4
What do you mean by Herbivorous, Carnivorous and Omnivorous? Give example.
Herbivores- Animals that eat only plants is called Herbivore. Example- Cow, Deer etc.
Carnivores- Animals that eat only other animals is called Carnivores. Example- Lion, Tiger etc.
Omnivores- Animals that eat both plants and animals is called Omnivores. Example- Bear, Human beings etc.
Is eating excess of food correct? Give reason to support your answer.
No, because it can create food poisoning. As we know that food has many nutrients which are required by our body for growth and development. But we take the food as per our need. And excess food is not accepted by our stomach and is vomited out. Although, excess food can harm our body as it is not digested easily.
Wild animal like tiger, wolf, lion and leopard do not eat plants. Does this mean that they can survive without plants? Can you provide a suitable explanation?
Animals like tiger, wolf, lion and leopard are carnivorous and do not eat plants. They hunt and eat herbivorous animals like deer, zebra, giraffe etc., which are dependent on plants for food.
If there are no plants, herbivorous animals will not be able to survive as they will have no food and would die of starvation. This will ultimately affect animals like tiger, wolf, lion and leopard that depend on herbivorous animals for food.
They will have nothing to eat and thus would not survive for this, it can be concluded that all heterotrophs directly or indirectly depend on plants for food and cannot survive without plants.
Does everyone around you get enough food to eat?
No, we know that there are many people amongst us, who do not get sufficient food because of the following reasons:
i) Lack of food
iii) Poor people cannot afford to buy enough food for themselves
We need to find ways by which more food can be grown in the country. That will not be enough; we will need to find ways to ensure that this food is made easily available to each and every one of us.

Do you find that all living beings need the same kind of food?
No. Different animals eat different kinds of food as per their body structure and internal organs. Depending on kind of food they eat, animals are divided into three basic categories:
Herbivores: Animals which feed on plants and plant products are called herbivores. Example: cow, goat, elephant, deer etc.
Carnivores: Animals which feed on other animals are called carnivores. Examples: lion, tiger, fox etc.
