Cell Organelles

Front

What are membrane-bound organelles?

Back

Organelles that are enclosed by membranes, found only in eukaryotic cells, such as the nucleus, mitochondria, and endoplasmic reticulum.

Front

What is the function of the cell membrane?

Back

It acts as a barrier that controls the movement of substances in and out of the cell, making it selectively permeable.

Front

What is the nucleolus?

Back

A small, dense structure within the nucleus where ribosomal RNA (rRNA) is produced and ribosome assembly begins.

Front

What is the mitochondria's role in the cell?

Back

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

Front

What is the nucleus?

Back

The nucleus is the organelle that contains the cell's genetic material (DNA) and controls cellular activities.

Front

What is the function of ribosomes?

Back

Ribosomes are responsible for protein synthesis, translating messenger RNA (mRNA) into polypeptide chains.

Front

What is the endoplasmic reticulum (ER)?

Back

A network of membranes involved in protein and lipid synthesis; it comes in two forms: rough (with ribosomes) and smooth (without ribosomes).

Front

What is the Golgi complex?

Back

An organelle that modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

Front

What is the role of chloroplasts?

Back

Chloroplasts are organelles found in plant cells that conduct photosynthesis, converting light energy into chemical energy.

Front

What is the central vacuole?

Back

A large organelle in plant cells that stores water, nutrients, and waste products, and helps maintain turgor pressure.
