- A.
The cell
- B.
The chloroplast
- C.
The nucleus
- D.
The cytoplasm

What is reproduction?
- A.
Making something
- B.
Something only some living things are able to do
- C.
When a living thing makes copies of itself
- D.
A type of severe weather

Which statement is true for all the following living things: ameba, rabbit, human, tree?
- A.
They carry out photosynthesis
- B.
The have similar means of locomotion
- C.
They are multicellular
- D.
They all contain at least one cell
- E.
They reproduce asexually
Correct Answer
D. They all contain at least one cellExplanation
Multicellular means they are made of more than one cell. An ameba is made of only one cell. Reproduce asexually means that it can make copies of itself completely on its own. Everything in the picture except the ameba needs one other organism like it to make copies of itself.Rate this question:

Which of the following statements is true?
- A.
Cells don't need nutrients
- B.
Chloroplasts contain a cells genetic material
- C.
Cells grow and reproduce
- D.
All non-living things are made of cells
Correct Answer
C. Cells grow and reproduceExplanation
All cells need nutrients. The nucleus is where genetic material (DNA) is found. Only living things are made of cells.Rate this question:

What do all organisms need to survive?
- A.
Energy
- B.
Blood
- C.
Carbon Dioxide
- D.
Soil
Correct Answer
A. EnergyExplanation
All living things need energy is one of the seven characteristics of all living things. This energy is usually in the form of food or heat. Not all living things have blood (plants, mold, single-cell organisms).Rate this question:
-
- 7.
To provide energy for the work that cells do, all cells need:
- A.
Chloroplasts
- B.
Nutrients
- C.
Atmospheric nitrogen
- D.
Carbon dioxide
Correct Answer
B. NutrientsExplanation
All cells need nutrients to provide energy for the work they do. Nutrients, such as carbohydrates, proteins, and fats, are broken down during cellular respiration to produce ATP, which is the main source of energy for cells. Chloroplasts are only found in plant cells and are responsible for photosynthesis, not energy production. Atmospheric nitrogen and carbon dioxide are not directly used for energy production in cells.Rate this question:

- 8.
Which of the following is true about all cells?
- A.
The genetic material is found in the cytoplasm
- B.
They grow and reproduce
- C.
They obtain and use nutrients
- D.
They are found in multicellular organisms
Correct Answer
D. They are found in multicellular organismsExplanation
THIS IS A VERY TRICKY QUESTION. For answer A, again, genetic material is found in the nucleus. Answer B describes all living things but not all cells. This is because not all cells grow and reproduce, even though all living things grown and reproduce. C is the correct answer because no cell can function without nutrients. That is what gives them energy. D is not correct because not all cells are found in multicellular organisms, some can only be found in single-cell organisms.Rate this question:

Which two structures (parts of a cell) are found ONLY in plant cells?
- A.
Mitochondria and nucleus
- B.
Endoplasmic reticulum and ribosomes
- C.
Cytoplasm and cell membranes
- D.
Chloroplasts and cell walls
Correct Answer
D. Chloroplasts and cell wallsExplanation
Chloroplasts are found only in plant cells and are responsible for photosynthesis, the process by which plants convert sunlight into energy. Cell walls are also unique to plant cells and provide structural support and protection. Mitochondria and nucleus are found in both plant and animal cells. Endoplasmic reticulum and ribosomes are present in all cells and are involved in protein synthesis. Cytoplasm and cell membranes are also found in both plant and animal cells. Therefore, the correct answer is chloroplasts and cell walls.Rate this question:

What is an internal structure?
- A.
Something that looks like a building
- B.
The parts of something that it is made of on the inside (like organelles)
- C.
The jell-o like stuff that is found in all cells (also known as cytoplasm)
- D.
The brain of the cell
Correct Answer
B. The parts of something that it is made of on the inside (like organelles)Explanation
The correct answer is "The parts of something that it is made of on the inside (like organelles)". An internal structure refers to the components or parts that make up the inside of something, such as an organism or a cell. In the context of this question, it specifically refers to the internal components of a cell, known as organelles. Organelles are specialized structures within a cell that perform specific functions, such as the nucleus, mitochondria, and endoplasmic reticulum. These organelles make up the internal structure of a cell and contribute to its overall function and organization.Rate this question:

Which part of the cell allows materials to enter or leave the cell?
- A.
Cytoplasm
- B.
Nuclear membrane
- C.
Cell membrane
- D.
Cell wall
Correct Answer
C. Cell membraneExplanation
The cell membrane is responsible for controlling the movement of substances in and out of the cell. It acts as a barrier, allowing some molecules to pass through while preventing others from entering or leaving. This selective permeability allows the cell to maintain its internal environment and regulate the exchange of nutrients, waste products, and other molecules with its surroundings. The cytoplasm is the gel-like substance within the cell, the nuclear membrane surrounds the nucleus, and the cell wall is a rigid structure found in plant cells that provides support and protection.Rate this question:

What does a chloroplast do?
Correct Answer
It carries out photosynthesisExplanation
If your answer is something like what the correct answer says, then you were right, even if it says you were wrong. The most important point is that you know it is where photosynthesis happens.Rate this question:

Human being
- B.
Grass
- C.
Bacterium

In which atmospheric layer does weather occur?
- A.
Troposphere
- B.
Stratosphere
- C.
Mesosphere
- D.
Thermosphere
- E.
Exosphere
Correct Answer
A. TropospHereExplanation
Weather happens only in the lowest layer. These layers are listed by how close they are to Earth's surface. Remember TSMTE: Timmy steals money to eat.Rate this question:

The cause of weather is
- A.
Gravity
- B.
The Moon
- C.
Nitrogen in the atmosphere
- D.
Uneven heating of Earth's surface
Correct Answer
D. Uneven heating of Earth's surfaceExplanation
Remember that Weather = Matter (Air and water) + energy (HEAT!)Rate this question:
-
- 16.
Changes in weather are related to changes in the position of
- A.
The Sun
- B.
The Moon
- C.
Air masses
- D.
Tectonic plates
Correct Answer
C. Air massesExplanation
Weather = matter (air and water) + energy (heat). Also, we did not talk at all about how the Sun or Moon changes position or about tectonic plates (those are UNDERGROUND!)Rate this question:
-
- 17.
Which of the following is caused by changes in Earth's atmosphere?
- A.
Tides
- B.
Eclipses
- C.
Earthquakes
- D.
Tornadoes
Correct Answer
D. TornadoesExplanation
The atmosphere is the air surrounding Earth, so the only answer could be a weather event (something that happens in air). Tides are movement of the oceans (hydrosphere). Eclipses are movement of the Moon in front of the Sun. Earthquakes are movement of the ground (lithosphere). Tornadoes are a weather event, in the air (atmosphere). If thunderstorms, blizzards, hurricanes, rain, or any other weather event were choices, those would have been correct, too.Rate this question:

Which layer of Earth's atmosphere contains the greatest concentration of gases?
- A.
Troposphere
- B.
Stratosphere
- C.
Mesosphere
- D.
Thermosphere
- E.
Exosphere
Correct Answer
A. TropospHereExplanation
Again, these layers are in order of how close they are to Earth's surface. The one on the bottom is being pressed down on most by the others (like a football player at the bottom of a pile), so its gases are pushed together (concentrated) more than the other layers.Rate this question:
