Cell Organelles

Front

What is the function of the nucleus in a cell?

Back

The nucleus acts as the cell's control center, containing the genetic material (DNA) and regulating cell activities.

Front

What organelle is responsible for photosynthesis in plant cells?

Back

Chloroplasts are the organelles that use sunlight to convert carbon dioxide and water into glucose (sugar) during photosynthesis.

Front

What is the role of the vacuole in plant and animal cells?

Back

Vacuoles store substances such as water, nutrients, and waste products; they are larger in plant cells.

Front

What is the function of mitochondria?

Back

Mitochondria are known as the powerhouse of the cell, converting energy from food into usable energy (ATP) for the cell.

Front

What is the cell wall and where is it found?

Back

The cell wall is a rigid outer layer that provides support and protection to plant cells; it is not found in animal cells.

Front

What is the endoplasmic reticulum (ER)?

Back

The endoplasmic reticulum is a network of membranes involved in protein and lipid synthesis; it comes in two forms: rough (with ribosomes) and smooth (without ribosomes).

Front

What are ribosomes and what is their function?

Back

Ribosomes are small structures that synthesize proteins by translating messenger RNA (mRNA) into amino acid sequences.

Front

What is the role of lysosomes in a cell?

Back

Lysosomes contain enzymes that break down waste materials and cellular debris, acting as the cell's cleanup crew.

Front

What is cytoplasm?

Back

Cytoplasm is the jelly-like substance within the cell membrane that contains organelles and is the site for many cellular processes.

Front

What is the function of the nuclear membrane?

Back

The nuclear membrane surrounds the nucleus, protecting it and regulating the movement of substances in and out of the nucleus.
