Cell organelles

What is a cell organelle?

A specialized subunit within a cell that has a specific function.

What is the function of the nucleus?

The nucleus stores the cell's genetic material and coordinates activities like growth and reproduction.

What is the function of mitochondria?

Mitochondria are the powerhouses of the cell, providing energy through cellular respiration.

What is the role of the endoplasmic reticulum (ER)?

The ER is involved in the synthesis and transport of proteins and lipids.

What is the difference between rough ER and smooth ER?

Rough ER has ribosomes and synthesizes proteins, while smooth ER is involved in lipid synthesis and lacks ribosomes.

What is the function of ribosomes?

Ribosomes are the sites of protein synthesis in the cell.

What do lysosomes do?

Lysosomes contain enzymes that digest waste and cellular debris.

What is the function of the Golgi apparatus?

The Golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or use within the cell.

What are chloroplasts?

Chloroplasts are organelles found in plant cells that conduct photosynthesis.

What is the role of the cell membrane?

The cell membrane regulates what enters and exits the cell, maintaining homeostasis.

What is cytoplasm?

Cytoplasm is the gel-like substance that fills the interior of the cell, where organelles are suspended.

What is the function of the cytoskeleton?

The cytoskeleton provides structural support, shape, and helps with cell movement.

What is the function of centrioles?

Centrioles are involved in cell division and organize the mitotic spindle.

What are secretory vesicles?

Secretory vesicles transport materials to the cell membrane for secretion.

What is the nucleolus?

The nucleolus is a dense region within the nucleus where ribosomal RNA is produced.

What is chromatin?

Chromatin is a complex of DNA and proteins found in the nucleus of eukaryotic cells, that packages DNA into a more compact, dense shape and regulates gene expression.

What is the nuclear envelope?

The nuclear envelope is a double membrane that encloses the nucleus, separating its contents from the cytoplasm.

What is a cell wall?

A cell wall is a rigid outer layer that provides structural support and protection to plant cells, fungi, and some bacteria.

What are large vascular tissues?

responsible for the transport of water, nutrients, and food throughout plants.

What is a vesicle?

A vesicle is a small membrane-bound sac that transports and stores substances within a cell.
