Correct Answer
C. Living things spontaneously generate from nonliving things.Explanation
The cell theory is a fundamental principle in biology that states that all living things are made of cells, all cells come from pre-existing cells, and cells are the basic unit of structure and function in living organisms. The answer "Living things spontaneously generate from nonliving things" contradicts the cell theory, as it suggests that living organisms can arise spontaneously from nonliving matter, which is not supported by scientific evidence.Rate this question:

Correct Answer
C. Cell wallExplanation
Animal cells are different from plant cells because they lack a cell wall. Plant cells have a rigid cell wall made of cellulose that provides structural support and protection. Animal cells, on the other hand, do not have a cell wall and instead have a flexible cell membrane that allows for greater movement and flexibility. This difference in cell structure is one of the key distinctions between animal and plant cells.Rate this question:

Vacuoles
- B.
Chromosomes
- C.
Chloroplasts
- D.
Mitochrondia
Correct Answer
C. ChloroplastsExplanation
Chloroplasts are responsible for capturing energy from sunlight and using it to produce food through the process of photosynthesis. They contain chlorophyll, a pigment that absorbs sunlight, and other necessary components for photosynthesis. Vacuoles are responsible for storing water and other substances, chromosomes are responsible for carrying genetic information, and mitochondria are responsible for producing energy in the form of ATP through cellular respiration. Therefore, chloroplasts are the correct answer as they specifically perform the function of capturing energy from sunlight for food production.Rate this question:

- A.
Ribosomes
- B.
Mitochrondia
- C.
Chloroplasts
- D.
Vacuoles
Correct Answer
D. VacuolesExplanation
Vacuoles are storage areas of the cell, particularly large in plant cells. They are membrane-bound organelles that store various substances such as water, nutrients, and waste products. Vacuoles play a vital role in maintaining the cell's turgidity, regulating osmotic balance, and storing important molecules. In plant cells, vacuoles are particularly large and occupy a significant portion of the cell's volume. They help maintain the shape and rigidity of the cell, store water for growth and development, and store pigments that contribute to the plant's coloration.Rate this question:

- A.
Mitosis
- B.
Diffusion
- C.
Osmosis
- D.
Meiosis
Correct Answer
B. DiffusionExplanation
Diffusion is the correct answer because it is the process by which molecules move from areas of lower concentration to areas of higher concentration in the cell. This movement occurs due to random molecular motion and does not require any energy input from the cell. Diffusion is an essential process for the transport of various substances, such as gases, nutrients, and waste products, across cell membranes. It plays a crucial role in maintaining the balance of molecules within cells and between different cellular compartments.Rate this question:
