Front

Which type of cell has no nucleus?

Back

Prokaryote: Prokaryotic cells are simple, unicellular organisms that lack a nucleus and membrane-bound organelles. Examples include bacteria.

Front

What is the monomer of nucleic acids?

Back

Nucleotides: Nucleotides are the building blocks of nucleic acids (DNA and RNA) and consist of a sugar, a phosphate group, and a nitrogenous base.

Front

Why are plants called producers?

Back

Plants are called producers because they make their own food through the process of photosynthesis, converting sunlight into chemical energy.

Front

Where do viruses reproduce?

Back

Inside of a host cell: Viruses cannot reproduce on their own; they must infect a host cell to replicate.

Front

Which type of cell is bigger?

Back

Eukaryotic: Eukaryotic cells are generally larger than prokaryotic cells and contain a nucleus and other organelles.

Front

What is the function of ribosomes?

Back

Ribosomes are the sites of protein synthesis in cells, translating messenger RNA (mRNA) into polypeptide chains.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy stored in glucose.

Front

What are the two main types of cells?

Back

Prokaryotic and Eukaryotic: Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and organelles.

Front

What is the role of mitochondria?

Back

Mitochondria are known as the powerhouse of the cell, generating ATP through cellular respiration.

Front

What is the structure of DNA?

Back

DNA is a double helix composed of two strands of nucleotides, with complementary base pairing (A-T and C-G) holding the strands together.
