Cell Structure
This organelle is known as the powerhouse of the cell.
What is the mitochondrion?
The passive movement of water across a selectively permeable membrane.
What is osmosis?
This process helps maintain a stable internal environment despite changes in the external environment.
What is homeostasis?
The process of programmed cell death.
What is apoptosis?
The type of cell that lacks a nucleus and membrane-bound organelles.
What is a prokaryote?
The structure that controls the movement of substances into and out of the cell.
What is the plasma membrane?
The movement of molecules from an area of high concentration to low concentration without energy input.
What is diffusion?
The hormone released by the pancreas to lower blood glucose levels.
What is insulin?
These enzymes break down cellular components during apoptosis.
What are caspases?
The phase of mitosis in which chromosomes first become visible and the nuclear envelope breaks down.
What is prophase?
These tiny structures are responsible for synthesizing proteins in the cell.
What are ribosomes?
This type of transport requires ATP to move substances against their concentration gradient.
What is active transport?
This pathway that counteracts a change, helping to maintain homeostasis.
What is negative feedback?
The term for the formation of small, membrane-bound cell fragments during apoptosis.
What is blebbing?
The process by which plants convert light energy into chemical energy.
What is photosynthesis?
The double membrane organelle that contains chlorophyll in plant cells.
What is the chloroplast?
The transport of large molecules into the cell by engulfing them in a vesicle.
What is endocytosis?
The process by which the body regulates its internal temperature.
What is thermoregulation?
The triggering of apoptosis by a death ligand binding to a cell.
What is the extrinsic pathway?
The hydrophilic region of a phospholipid.
What is a phosphate head?
The organelle responsible for modifying, packaging, and transporting proteins.
What is the Golgi apparatus?
This process involves the use of transport proteins to move substances across the plasma membrane without energy.
What is facilitated diffusion?
Glucose is converted into their molecule when being stored in cells.
What is glycogen?
A failure of apoptosis may result in this type of uncontrolled cell growth.
What is cancer?
This form of reproduction allows females to produce offspring without fertilization by a male.
What is parthenogenesis?
