1.

Seeds will  ___________  if there is no water.

Answer: Not grow
Explanation:
Seeds need water to start the germination process. Without water, seeds will not grow because water activates the enzymes that initiate growth. Water also helps to soften the seed coat, allowing the plant embryo to emerge and start developing roots and shoots. Without adequate water, the necessary biochemical reactions cannot occur, and the seed remains dormant. This illustrates the critical role of water in plant biology and the initial stages of a plant's life cycle, highlighting why proper watering is essential for successful seed germination and plant growth.
2.

A ____________ has only one large seed.

Answer: Lychee
Explanation:
 A lychee has only one large seed. The lychee fruit is known for its sweet and aromatic flesh, which surrounds a single, large seed. This characteristic differentiates it from fruits like watermelon, which contains many seeds, or durian, which has multiple seeds within its large segments. The large seed of the lychee is covered by a rough, red rind that is typically peeled away to reveal the edible flesh. Understanding the seed structure of different fruits helps in learning about plant reproduction and the diversity of fruit characteristics.
3.

Animals who only eat the flesh of other animals are known as

Answer: Carnivores
Explanation:
Animals who only eat the flesh of other animals are known as carnivores. Carnivores have adaptations such as sharp teeth and claws that help them hunt and consume meat. Examples of carnivores include lions, tigers, and eagles. Unlike herbivores, which eat plants, and omnivores, which eat both plants and animals, carnivores rely solely on animal flesh for their nutritional needs. This dietary classification is crucial for understanding food chains and ecosystems, as carnivores play a vital role in maintaining the balance by controlling the population of other animals.
4.

Human beings have _________ sense organs. 

Answer: Five
Explanation:
Human beings have five sense organs: eyes, ears, nose, tongue, and skin. These organs are responsible for the senses of sight, hearing, smell, taste, and touch, respectively. Each sense organ detects different types of stimuli from the environment and sends information to the brain for processing. For example, eyes detect light and allow us to see, while ears detect sound waves for hearing. Understanding the five sense organs helps us appreciate how we perceive and interact with the world around us.
5.

What is the name of the planet we live on?

Answer: Earth
Explanation:
 The planet we live on is called Earth. It is the third planet from the Sun in our solar system and the only known planet that supports life. Earth has a diverse environment with various ecosystems, abundant water, and a protective atmosphere, making it suitable for humans, animals, and plants. Understanding our planet's unique characteristics helps us appreciate the importance of taking care of our environment and the interconnectedness of all living organisms on Earth.
6.

How many planets are there in our solar system?

Answer: 8
Explanation:
There are 8 planets in our solar system. These planets, in order from closest to the Sun to farthest, are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Previously, Pluto was considered the ninth planet, but it was reclassified as a dwarf planet by the International Astronomical Union (IAU) in 2006. Understanding the number and order of planets helps in studying the structure and dynamics of our solar system, as well as the characteristics and composition of each planet.
7.

What do plants need to make their food?

Answer: Sunlight
Explanation:
Plants need sunlight to make their food through a process called photosynthesis. They use sunlight, water, and carbon dioxide to create oxygen and glucose, which is their food. The sunlight provides the energy needed for this process to happen. Without sunlight, plants would not be able to produce the food they need to grow and survive. This is why you'll often see plants growing towards the light or in areas where they can get plenty of sunlight.
8.

What is the main gas we need to breathe to stay alive?

Answer: Oxygen
Explanation:
The main gas we need to breathe to stay alive is oxygen. Our bodies use oxygen to help our cells produce energy. When we inhale, oxygen from the air enters our lungs and is then carried by our blood to all parts of our body. This oxygen is crucial for our cells to function properly. Without it, we would not be able to survive for very long, highlighting its importance for all living beings.
9.

What part of the plant grows under the ground?

Answer: Roots
Explanation:
The part of the plant that grows under the ground is called the roots. Roots anchor the plant in the soil and absorb water and nutrients that the plant needs to grow. They also store food for the plant. Roots can grow very deep or spread out wide, depending on the type of plant. Understanding the role of roots helps us appreciate how plants get the materials they need from the soil to survive and thrive.
10.

What force pulls objects toward the Earth?

Answer: Gravity
Explanation:
Gravity is the force that pulls objects toward the Earth. It is the reason why we stay on the ground and why things fall when we drop them. Gravity is a natural force that acts between all objects with mass, and it is what gives us weight. Without gravity, everything would float away into space. Understanding gravity helps explain many everyday experiences, such as why we can walk on the ground and why objects fall.
