10.
Green plants produce their own food through a process known as photosynthesis because they are categorized as __________________.
Correct Answer
D. AutotropHs
Explanation
Green plants are categorized as autotrophs because they have the ability to produce their own food through photosynthesis. Autotrophs are organisms that can synthesize organic compounds from inorganic substances, such as carbon dioxide and water, using sunlight as an energy source. In photosynthesis, green plants use chlorophyll to capture sunlight and convert it into chemical energy, which is then used to convert carbon dioxide and water into glucose and oxygen. This process allows green plants to sustain themselves and provide energy for other organisms in the food chain.
11.
Plants use the organelle _________________in their cells to capture energy in sunlight.
Correct Answer
B. Chloroplasts
Explanation
Plants use chloroplasts in their cells to capture energy in sunlight. Chloroplasts are organelles found in plant cells that contain chlorophyll, a pigment that absorbs sunlight. Through a process called photosynthesis, chloroplasts convert light energy into chemical energy, which is then used by the plant for growth and other metabolic processes. The chloroplasts contain specialized structures called thylakoids, where the light-dependent reactions of photosynthesis occur, and the stroma, where the light-independent reactions occur. Overall, chloroplasts play a crucial role in allowing plants to harness the energy from sunlight and convert it into usable energy.
12.
Cell growth is the increase in size and __________ of an organism.
Correct Answer
C. Mass
Explanation
Cell growth refers to the increase in both size and mass of an organism. As cells divide and replicate, they accumulate more cellular material, leading to an overall increase in mass. This increase in mass is essential for the development and functioning of an organism. Therefore, the correct answer is "mass".
13.
Cells repair and reproduce through a sophisticated process called _____________________.
Correct Answer
D. Mitosis
Explanation
Mitosis is the correct answer because it is the process by which cells repair and reproduce. During mitosis, a single cell divides into two identical daughter cells, each containing the same number of chromosomes as the parent cell. This process is essential for growth, tissue repair, and asexual reproduction in organisms.
14.
Reproduction is the process by which new organisms (offspring) are generated (created).
Correct Answer
A. True
Explanation
The statement is true because reproduction is indeed the process through which new organisms are created. It involves the production of offspring that inherit genetic material from their parents, ensuring the continuity of a species. Through various methods such as sexual or asexual reproduction, organisms can generate new individuals and pass on their genetic information to the next generation.
15.
Sexual reproduction creates offspring that has the characteristics of one parent or the other.
Correct Answer
B. False
Explanation
Sexual reproduction creates offspring that has a combination of characteristics from both parents. This is because during sexual reproduction, genetic material from both parents is combined to form a unique set of genes in the offspring. This results in offspring that may inherit traits from both parents, rather than just having the characteristics of one parent or the other. Therefore, the statement "Sexual reproduction creates offspring that has the characteristics of one parent or the other" is false.
16.
Asexual reproduction creates offspring that is an identical copy of the parent.
Correct Answer
A. True
Explanation
Asexual reproduction is a type of reproduction where offspring are produced without the involvement of gametes or the fusion of genetic material from two parents. In this process, a single parent organism replicates its genetic material to create an identical copy of itself. The offspring produced through asexual reproduction are genetically identical to the parent, as there is no mixing or recombination of genetic material. Therefore, the statement that asexual reproduction creates offspring that is an identical copy of the parent is true.
17.
Anything that causes a living organism to react is called a __________________.
Correct Answer
B. Stimulus
Explanation
A stimulus is anything that causes a living organism to react. It can be a physical or chemical factor that triggers a response in an organism. This response can be a behavior, a physiological change, or both. Stimuli can come from the external environment, such as light or sound, or from within the organism, such as hunger or pain. The correct answer, stimulus, accurately describes the concept of something that elicits a reaction in a living organism.
