1.
What type of plant makes food all year?
Correct Answer
C. Evergreen
Explanation
Evergreen plants retain their leaves throughout the year, allowing them to perform photosynthesis and make food continuously. Unlike deciduous plants that shed their leaves during certain seasons, evergreen plants have adaptations that enable them to survive in various climates and continue their metabolic processes year-round. This includes having specialized structures and mechanisms to store and efficiently use nutrients and water, ensuring a constant food supply. Chlorophyll and photosynthesis are essential processes for all plants, but evergreen plants specifically maintain their ability to make food consistently.
2.
What is the first stage of life for many plants?
Correct Answer
B. Seed
Explanation
The first stage of life for many plants is the seed. Seeds are the reproductive structures of plants that contain the embryo and a food source to support its growth. When conditions are favorable, seeds germinate and develop into new plants. This stage is crucial for the survival and propagation of plant species.
3.
What is the process a plant uses to make food?
Correct Answer
A. pHotosynthesis
Explanation
Plants use photosynthesis to make food. This is the process in which they convert sunlight, carbon dioxide, and water into glucose and oxygen. The chlorophyll in their cells captures sunlight and uses it to convert carbon dioxide and water into glucose, which is a form of energy that plants can use. Oxygen is released as a byproduct of this process. So, photosynthesis is the correct answer because it describes the specific process that plants use to make food.
4.
What part of the plant is the food factory?
Correct Answer
D. Leaf
Explanation
The leaf is the food factory of the plant because it contains chloroplasts, which are responsible for photosynthesis. Photosynthesis is the process by which plants convert sunlight, carbon dioxide, and water into glucose (food) and oxygen. The leaf has a large surface area and is exposed to sunlight, allowing it to absorb maximum sunlight for photosynthesis. Additionally, the leaf has veins that transport water and nutrients to the cells, further supporting its role as the food factory of the plant.
5.
The __________ is the part of the plant that grows underground.
Correct Answer
B. Root
Explanation
The root is the part of the plant that grows underground. It anchors the plant in the soil and absorbs water and nutrients from the soil. The root also stores food for the plant and can sometimes grow above the ground in certain plant species.
6.
The __________ connects the plant's leave to the roots.
Correct Answer
A. Stem
Explanation
The stem connects the plant's leaves to the roots. The stem acts as a support system for the plant, allowing nutrients and water to flow between the leaves and the roots. It also helps in the transportation of sugars produced during photosynthesis from the leaves to other parts of the plant. Without the stem, the leaves and roots would not be able to communicate and the plant would not be able to survive.
7.
What type of plant looses its leaves every year?
Correct Answer
D. Deciduous
Explanation
Deciduous plants are the type of plants that lose their leaves every year. This is a natural process that occurs during the fall season. The leaves of deciduous plants change color and eventually fall off, allowing the plant to conserve energy during the colder months. This adaptation helps the plant survive harsh winter conditions and prepare for new growth in the following spring. Coniferous plants, on the other hand, have needle-like leaves that are retained year-round. Evergreen plants also retain their leaves throughout the year, but they do not shed them all at once like deciduous plants. Photosynthesis is the process by which plants convert sunlight into energy and is not directly related to leaf loss.
8.
What is the substance called that helps plants turn enerygy from the sun into food?
Correct Answer
B. ChloropHyll
Explanation
Chlorophyll is the correct answer because it is the substance responsible for photosynthesis in plants. Photosynthesis is the process by which plants convert sunlight into energy to produce food. Chlorophyll is a pigment found in the chloroplasts of plant cells that absorbs light energy and uses it to convert carbon dioxide and water into glucose and oxygen. Without chlorophyll, plants would not be able to carry out photosynthesis and produce their own food.
9.
What is the most important thing a plant needs to live?
Correct Answer
C. Water
Explanation
Plants require water for their survival as it plays a crucial role in various physiological processes. Water is essential for photosynthesis, the process by which plants convert sunlight into energy. It also helps in the transportation of nutrients and minerals from the soil to different parts of the plant. Water is also responsible for maintaining the turgidity of plant cells, which provides structural support. Without an adequate water supply, plants would not be able to carry out these vital functions and would eventually die.
10.
What is one thing plants need to make food?
Correct Answer
B. Sunlight
Explanation
Plants need sunlight to make food through a process called photosynthesis. During photosynthesis, plants use energy from sunlight to convert carbon dioxide and water into glucose and oxygen. Sunlight provides the energy needed for this chemical reaction to occur. Without sunlight, plants would not be able to produce food and would not survive.
11.
What is one way scientists classify plants?
Correct Answer
C. Leaf type
Explanation
Scientists classify plants based on their leaf type. This is because the structure and shape of leaves can provide important information about a plant's adaptation to its environment, its growth habits, and its relationship with other organisms. Leaf type classification can help scientists identify and categorize different plant species, as well as understand their ecological roles and evolutionary relationships. By studying leaf characteristics, scientists can gain insights into a plant's physiology, anatomy, and reproductive strategies, making leaf type an important criterion for plant classification.
12.
Plants make seeds in either __________ or __________.
Correct Answer
C. Flowers, cones
Explanation
Plants make seeds in either flowers or cones. Flowers are reproductive structures in angiosperms that contain the female reproductive organs, the ovary, and the male reproductive organs, the stamen. The ovary develops into a fruit, which contains the seeds. Cones, on the other hand, are reproductive structures in gymnosperms, such as pine trees. They contain the female reproductive structures, called ovules, which develop into seeds. Therefore, both flowers and cones are involved in the production of seeds in plants.
13.
Seeds look __________ the flower they will become.
Correct Answer
C. Different than
Explanation
Seeds look different than the flower they will become because seeds are usually small, hard, and often have a protective outer coating, while flowers are larger, softer, and have colorful petals. The transformation from a seed to a flower involves a process called germination, where the seed absorbs water and nutrients, and eventually develops into a plant with stems, leaves, and flowers. Therefore, the appearance of a seed is distinct and dissimilar from the appearance of the flower it will eventually grow into.
14.
The food plants make through photosynthesis is __________.
Correct Answer
A. Sugar
Explanation
Food plants make sugar through the process of photosynthesis. During photosynthesis, plants use sunlight, carbon dioxide, and water to produce glucose, which is a type of sugar. This glucose is then used by the plant as a source of energy for growth and development. Additionally, some of the glucose is converted into other types of sugars, such as fructose and sucrose, which are transported throughout the plant to provide energy to different parts of the plant or stored for later use. Therefore, the correct answer is sugar.
15.
During photosynthesis, plants take in __________ and give off __________.
Correct Answer
C. Carbon dioxide, oxygen
Explanation
During photosynthesis, plants take in carbon dioxide and give off oxygen. Photosynthesis is the process by which plants convert carbon dioxide and water into glucose (food) and oxygen, using sunlight as the energy source. The carbon dioxide is absorbed through tiny openings called stomata on the leaves, while the oxygen is released back into the atmosphere. This process is essential for the survival of plants and also plays a crucial role in maintaining the oxygen levels in the Earth's atmosphere, which is vital for supporting life.
