-
What is the function of the nucleus?
To control and regulate all processes within a cell.
-
What is cytoplasm?
A thick, clear, jelly-like substance containing organelles, water, and other life-supporting materials.
-
Which organelles exist as the primary site of cellular respiration?
The mitochondria
-
In which organelle is DNA (hereditary material transferred through reproduction) stored?
The nucleus
-
What are the vacuoles?
Organelles intended for storage of energy, water, and occasionally, waste.
-
What is the purpose of a selectively permeable membrane?
- To provide a barrier between the internal structure of the cell and the rest of the body
- To regulate the flow of materials in and out of the cell
- To provide support and protection
-
What process is executed by the Golgi body?
The organization and assembly of proteins into vesicles
-
What are ribosomes?
Small bodies responsible for the production of proteins
-
The endoplasmic reticulum (E.R) serves as________________
A network of membrane-covered channels which transport materials (particularly ribosomes) throughout the cell.
-
What is the difference between a smooth E.R and a rough E.R?
The smooth endoplasmic reticulum is not carrying ribosomes, wheras the rough endoplasmic reticulum is.
-
What are the functions of the lysosome?
To break down cell wastes and organelles which fail to serve their purposes within the cell.
-
Which two cell components only exist in organisms of the plantae kingdom?
- -Cell wall: A rigid structure surrounding the selectively permeable membrane employed mainly for protection
- -Chloroplasts: Plastids containing clorophyll which are responsible for photosynthesis (the conversion of sunlight and carbon dioxide into glucose and oxygen)
