What are cells often compared to in the video?

• Atoms

• Blocks

• Bricks

• Molecules

Answer explanation

In the video, cells are often compared to blocks, highlighting how they serve as the fundamental building units of life, similar to how blocks are used to construct larger structures.

What is the smallest unit that can carry out all functions of life?

• Atom

• Organ

• Tissue

• Cell

Answer explanation

The cell is the smallest unit that can perform all life functions, including metabolism, growth, and reproduction. Unlike atoms, organs, and tissues, which are made up of cells, the cell itself is the fundamental building block of life.

What tool is often needed to see most cells?

• Telescope

• Magnifying glass

• Microscope

• Binoculars

Answer explanation

A microscope is essential for viewing most cells, as it provides the necessary magnification to see their structures clearly. Other tools like telescopes and binoculars are not suitable for this purpose.

What does 'unicellular' mean?

• Made of multiple cells

• Made of one cell

• Without a nucleus

• Non-living

Answer explanation

'Unicellular' refers to organisms that are made of one cell. This distinguishes them from multicellular organisms, which consist of multiple cells. Therefore, the correct answer is 'Made of one cell'.

Which of the following is an example of a unicellular organism?

• Human

• Dog

• E-coli bacteria

• Tree

Answer explanation

E-coli bacteria is a unicellular organism, meaning it consists of a single cell. In contrast, humans, dogs, and trees are multicellular organisms made up of many cells.

What are organisms made of many cells called?

• Singular organisms

• Multicellular organisms

• Cellular colonies

• Complex cells

Answer explanation

Organisms made of many cells are called multicellular organisms. This term distinguishes them from unicellular organisms, which consist of a single cell. The other options do not accurately describe this characteristic.

What function do specialized cells NOT perform?

• Absorb nutrients

• Transmit information

• Defend against viruses

• Photosynthesis in animals

Answer explanation

Specialized cells perform various functions like absorbing nutrients, transmitting information, and defending against viruses. However, animals do not perform photosynthesis, which is a function of plant cells.

What is the process that makes food using sunlight called?

• Cellular respiration

• Chlorophyllation

• Fertilization

• Photosynthesis

Answer explanation

The process that makes food using sunlight is called photosynthesis. During photosynthesis, plants convert sunlight, carbon dioxide, and water into glucose and oxygen, which is essential for their growth.

Where does photosynthesis occur in plant cells?

• Mitochondria

• Cytosol

• Chloroplasts

• Ribosomes

Answer explanation

Photosynthesis occurs in chloroplasts, which are specialized organelles in plant cells. They contain chlorophyll, the pigment that captures sunlight, enabling the conversion of light energy into chemical energy.

What pigment captures light energy in plants?

• Hemoglobin

• Chlorophyll

• Keratin

• Glucose

Answer explanation

Chlorophyll is the pigment in plants that captures light energy for photosynthesis, allowing them to convert sunlight into chemical energy. Hemoglobin is found in blood, keratin is in hair and nails, and glucose is a sugar, not a pigment.
