Biology Flashcards
(18 cards)
What are animal cells?
Animal cells are eukaryotic cells that lack a cell wall and have a plasma membrane.
What is the function of the Golgi apparatus?
The Golgi apparatus modifies, sorts, and packages proteins for secretion or delivery to other organelles.
What is the role of mitochondria?
Mitochondria are the powerhouses of the cell, converting nutrients into adenosine triphosphate (ATP) to be used by the cells.
What is a ribosome?
Ribosomes are cellular structures that synthesize proteins.
What is the plasma membrane?
The plasma membrane is a biological membrane that separates and protects the interior of all cells from the outside environment.
What is cytoplasm?
Cytoplasm is the jelly-like substance within the cell membrane that contains organelles and is the site of many cellular processes.
What is the function of lysosomes?
Lysosomes contain hydrolytic enzymes that break down waste materials and cellular debris.
What is the nucleus?
The nucleus is the largest organelle in the cell, containing the genetic material and controlling all cell activities.
What is the function of the nucleolus?
The nucleolus is responsible for producing ribosomes.
What are the two types of endoplasmic reticulum?
The two types of endoplasmic reticulum are rough endoplasmic reticulum and smooth endoplasmic reticulum.
What is the function of the rough endoplasmic reticulum?
The rough endoplasmic reticulum is involved in protein synthesis and processing.
What is the function of the smooth endoplasmic reticulum?
The smooth endoplasmic reticulum is involved in lipid synthesis and detoxification processes.
What is the nuclear membrane?
The nuclear membrane is a double-layered structure that encloses the nucleus of a cell.
What is a plant cell?
A plant cell is a type of cell that is characterized by a rigid cell wall, chloroplasts, and a large central vacuole.
What is the function of the cell wall?
The cell wall provides structural support and protection to plant cells.
What is the plasma membrane?
The plasma membrane is the outer boundary of the cell that regulates the movement of substances in and out.
What is the role of the Golgi apparatus?
The Golgi apparatus processes and packages proteins and lipids for secretion or delivery to other organelles.
