Organelles and Structural Components
What is an Organelle?
An organelle is specialised sub-unit within a cell that performs a specific function.
What is Metabolism?
Any complex biochemical process whereby cells are nourished for growth, repair, function, and reproduction.
Active transport and Passive transport
What is the technical term for cell division, the reproduction of a single human body cell into two new identical cells?
Mitosis
Chromosomes, that contain our DNA, are found inside which organelle?
The Nucleus
What are the two phases of metabolism and their function?
Anabolism: to build up/construct
Catabolism: to breaking down/deconstruct
When the cell uses pumps to transport substances across the membrane it's called?
Active cell transport
What is the orderly sequence of events by which a cell duplicates called and what three phases does it consist of?
The cell cycle:
Interphase
Mitotic Phase
Cytokinesis
Which organelle are membrane-enclosed vesicles filled with enzymes capable of breaking down other substances?
Lysosomes
What is one example of an anabolism in the body?
-Building new tissues
-Creating life
-Cellular reproduction
-Ribosomes producing proteins
The movement of water molecules across a selectively permeable membrane from an area of high concentration to low concentration is called?
Osmosis
Which phase is the cell duplicating it's parts?
Hint: the cells "preparation" phase
Interphase
What are the two types of Protoplasm and where are each of them found?
Cytoplasm: found between the cell membrane and the nuclear membrane.
Nucleoplasm: found inside the nucleus.
What is an example of catabolism in the body?
-Lysosomes breaking down waste
-Our digestive system breaking down food
-The Keratinization Process
What is the term that means a cell is taking in matter by its membrane to form a vacuole?
Endocytosis
Endo: enter
Cytosis: cell action
Mitotic phase is responsible for the distribution of ______________________ into two separate nuclei.
two sets of chromosomes
The cell membrane is "semi-permeable", what does that mean?
This means that some substances are allowed to enter while others are not.
What does the body need in order for metabolism to occur?
Energy
What is the movement of substances out of the cell.
Exocytosis
Exo: exiting
Cytosis: cell action
What is the final stage of mitosis where the cell membrane and cytoplasm divide and two identical daughter cells are formed?
Cytokinesis
