1.
All living things need _______________ to grow.
Correct Answer
B. Energy
Explanation
All living things need energy to grow. Energy is required for various biological processes such as metabolism, cell division, and synthesis of new molecules. Without energy, living organisms would not be able to carry out essential functions and their growth would be hindered. While vegetables and sunlight are important for certain aspects of growth, energy is the fundamental requirement for all living things.
2.
_______________ help keep plants in the ground.
Correct Answer
C. Roots
Explanation
Roots help keep plants in the ground by anchoring them securely in the soil. They provide stability and support to the plant, preventing it from being easily uprooted or blown away by strong winds. Additionally, roots also absorb water and nutrients from the soil, which are essential for the plant's growth and survival. Without roots, plants would not be able to obtain the necessary resources and would be more susceptible to being uprooted or drying out.
3.
You can use a ___________________ to look at cells.
Correct Answer
A. Microscope
Explanation
A microscope is a device that allows us to observe and study cells. It uses a combination of lenses and light to magnify the image of the cells, making them visible to the human eye. Microscopes are specifically designed for the purpose of examining small objects such as cells, and they provide a higher level of magnification and resolution compared to other devices like telescopes or magnifying glasses. Therefore, a microscope is the most suitable tool for looking at cells.
4.
The ___________tells a plant how to do its job.
Correct Answer
B. Nucleus
Explanation
The nucleus contains the plant's genetic material, including DNA, which carries the instructions or "blueprint" for how the plant functions and develops. It controls the plant's growth, metabolism, and reproduction by directing the synthesis of proteins and other molecules necessary for these processes. Therefore, the nucleus can be considered as the control center or command center of the plant, telling it how to perform its various functions.
5.
Tulips and daffodils do not grow from seeds, but from _____________________.
Correct Answer
C. Bulbs
Explanation
Tulips and daffodils do not grow from seeds because they are not propagated through sexual reproduction. Instead, they grow from bulbs. Bulbs are underground storage structures that contain all the necessary nutrients and energy for the plant to grow. When the bulb is planted, it produces new shoots and roots, eventually growing into a mature plant. This method of reproduction allows tulips and daffodils to produce genetically identical offspring, ensuring the preservation of desirable traits.
6.
All living things are _____________________.
Correct Answer
B. Organisms
Explanation
Living things refer to any organisms that possess the characteristics of life, such as the ability to grow, reproduce, respond to stimuli, and maintain homeostasis. The term "organisms" encompasses all living entities, including animals, plants, fungi, and microorganisms. Therefore, the correct answer is "organisms" because it includes all living things regardless of their specific classification or complexity.
7.
The changes that happen to an organism during its life is the __________________________.
Correct Answer
A. Life cycle
Explanation
The changes that happen to an organism during its life is referred to as its life cycle. The life cycle encompasses all the stages an organism goes through from birth or germination to death or senescence. It includes processes such as growth, development, reproduction, and aging. The life cycle is a fundamental concept in biology and helps us understand the different phases and transitions that occur in an organism's life.
8.
___________________________ is a series of changes in appearance.
Correct Answer
C. MetamorpHosis
Explanation
Metamorphosis is the correct answer because it refers to a series of changes in appearance. This term is commonly used to describe the transformation that certain organisms undergo during their life cycle, such as the change from a caterpillar to a butterfly.
9.
The building blocks that make up every part of an organism is called a ____________________.
Correct Answer
B. Cell
Explanation
A cell is the basic unit of structure and function in living organisms. It is the building block that makes up every part of an organism, including tissues, organs, and systems. Cells contain various organelles, such as the nucleus and cytoplasm, which perform specific functions within the cell. Therefore, the correct answer for this question is "cell."
10.
A / An _______________ is an organism wrapped in a cocoon, it doesn't move or eat.
Correct Answer
A. Pupa
Explanation
A pupa is an organism wrapped in a cocoon, it doesn't move or eat. This stage in the life cycle of insects is characterized by a period of transformation from the larval stage to the adult stage. During this time, the insect undergoes significant changes in its body structure and organs, preparing for its emergence as an adult. The pupa is typically immobile and does not feed, as its main focus is on internal development.
11.
An animal cell is different from a plant cell because it doesn't have ____________________ or ____________________.
Correct Answer
C. A cell wall, chloroplasts
Explanation
An animal cell is different from a plant cell because it lacks a cell wall, which is a rigid structure that provides support and protection in plant cells. Additionally, animal cells do not have chloroplasts, which are responsible for photosynthesis in plant cells.
12.
Which of the following is NOT a way living and nonliving things are different?
Correct Answer
B. Living things move.
Explanation
Living things move is the correct answer because while it is true that living things reproduce, react to changes around them, and use energy to grow, not all living things necessarily move. Some living things, such as plants, do not have the ability to move from one place to another. Therefore, movement is not a universal characteristic of all living things, making it the correct answer.
