1.
Plants have 3 main parts?
Correct Answer
A. True
Explanation
Plants have three main parts: roots, stems, and leaves. The roots anchor the plant in the ground and absorb water and nutrients from the soil. The stems provide support and transport water, nutrients, and sugars throughout the plant. The leaves are the main site of photosynthesis, where sunlight is converted into energy for the plant. These three parts are essential for the survival and growth of plants, making the statement "Plants have 3 main parts" true.
2.
Scientists are called what?
Correct Answer
B. Botanists
Explanation
Botanists are scientists who specialize in the study of plants. They have a deep understanding of plant biology, ecology, and taxonomy. They conduct research to learn about plant growth, reproduction, and adaptation to different environments. Botanists also play a crucial role in conservation efforts and the development of sustainable agriculture. Therefore, the term "botanists" is the correct answer to the question.
3.
What are natural resources?
Correct Answer
D. Come from the Earth
Explanation
Natural resources are materials or substances that are found in nature and are used by humans for various purposes. These resources are not created by humans but are derived from the Earth. Examples of natural resources include minerals, water, air, forests, and fossil fuels. These resources are essential for the survival and development of human civilization, as they provide raw materials for industries, support ecosystems, and contribute to the overall well-being of society.
4.
True or False.. Plants and trees give us food, shade, water and wood
Correct Answer
A. True
Explanation
Plants and trees provide us with various essential resources. They produce food through photosynthesis, supplying us with fruits, vegetables, and grains. They also offer shade, protecting us from the sun's harmful rays. Additionally, plants play a crucial role in the water cycle by absorbing and releasing water vapor, helping to maintain the water supply. Lastly, trees provide us with wood, which is used for construction, furniture, and various other purposes. Therefore, the statement that plants and trees give us food, shade, water, and wood is true.
5.
True or False.. Pollution is good for our land?
Correct Answer
B. False
Explanation
Pollution is not good for our land. It can have harmful effects on the environment, ecosystems, and human health. Pollution can contaminate soil, water, and air, leading to the degradation of land and the destruction of habitats. It can also contribute to climate change and the loss of biodiversity. Therefore, it is important to reduce pollution and adopt sustainable practices to protect our land and the planet.
6.
What are basic needs to help plants grow?
Correct Answer
C. Water and soil
Explanation
Water and soil are the basic needs to help plants grow. Water is essential for plants as it helps in the process of photosynthesis, where plants convert sunlight into energy. It also aids in the transportation of nutrients from the soil to different parts of the plant. Soil provides plants with necessary nutrients and minerals for their growth. It also acts as a medium for anchoring the roots and provides support to the plant. The moon, snow, and a blanket do not play a significant role in the growth of plants.
7.
What is the main function of the roots in a plant?
Correct Answer
C. Feed the plant with water and minerals
Explanation
The main function of the roots in a plant is to feed the plant with water and minerals. Roots absorb water and essential nutrients from the soil, which are then transported to the rest of the plant for growth and development. Without roots, plants would not be able to obtain the necessary resources for survival.
8.
Why is soil important to a plant's growth?
Correct Answer
B. Gives the plant nutrients
Explanation
Soil is important to a plant's growth because it provides essential nutrients that plants need to survive and thrive. These nutrients include nitrogen, phosphorus, potassium, and other minerals that are necessary for plant growth and development. Without these nutrients, plants would not be able to carry out vital processes such as photosynthesis, nutrient absorption, and the production of proteins and enzymes. Therefore, soil plays a crucial role in providing plants with the necessary nutrients for their growth and overall health.
9.
The stem is located on what part of the plant?
Correct Answer
A. In the middle of the plant
Explanation
The stem is located in the middle of the plant. The stem serves as the main structural support for the plant, connecting the roots to the leaves and flowers. It provides stability and allows for the transport of water, nutrients, and sugars throughout the plant. The stem also contains vascular tissues, such as xylem and phloem, which play a crucial role in the movement of fluids and nutrients. Overall, the stem is an essential part of the plant's anatomy and is typically found in the middle portion of the plant.
10.
True or False.. Pushes and pulls are forces?
Correct Answer
A. True
Explanation
Pushes and pulls are indeed forces. A force is any interaction that can change the motion of an object. When an object is pushed or pulled, it experiences a force that can cause it to move or change direction. Therefore, the statement "Pushes and pulls are forces" is true.
11.
What to natural resoruces help provide?
Correct Answer
A. Basic needs
Explanation
Natural resources help provide basic needs such as food, water, shelter, and energy. These resources are essential for human survival and are derived from the environment. Examples of natural resources include air, water, land, minerals, forests, and wildlife. They are used to meet the fundamental requirements of human beings and support their daily lives.
12.
What do leaves do for a plant?
Correct Answer
C. Producing foods
Explanation
Leaves are the primary site for photosynthesis in plants, where they convert sunlight, water, and carbon dioxide into glucose and oxygen. This process is crucial for a plant's survival as it provides the energy and nutrients needed for growth and development. Therefore, the correct answer is "producing foods."
13.
What are some basic needs for natural resources?
Correct Answer
B. Water, oil and air
Explanation
Natural resources are materials or substances that occur naturally and can be used for economic gain. Water, oil, and air are considered basic needs for natural resources because they are essential for various human activities and industries. Water is necessary for drinking, agriculture, and industrial processes. Oil is a crucial energy source and is used in transportation, manufacturing, and heating. Air is required for breathing and is also used in various industrial processes.
14.
Do we get newspapers and books from plants and trees?
Correct Answer
A. True
Explanation
Newspapers and books are made from paper, and paper is primarily made from wood pulp, which is obtained from trees. Therefore, it is true that we get newspapers and books from plants and trees.
15.
What can we do to help the Earth?
Correct Answer
C. Reduce, Reuse and Recycle
Explanation
The correct answer is "Reduce, Reuse and Recycle." This is because by reducing our consumption, reusing items instead of throwing them away, and recycling materials, we can minimize waste and conserve resources. These actions help to protect the environment, reduce pollution, and mitigate the negative impacts of human activities on the Earth.
