YEAR 11 BIOLOGY MODULE 1 CELLS AS
THE BASIS OF LIFE QUESTIONS AND
VERIFIED ANSWERS
GRADED A+
QUESTIONS & ANSWERS
Organelle. ANSWER - A specialised structure or compartment within a cell that has a
specific function.
Nucleus. ANSWER - The organelle containing DNA in a eukaryotic cell; it functions to
coordinate cellular activities.
Mitochondria. ANSWER - Organelles within the cytoplasm that are the site of aerobic
cellular respiration, releasing energy for the cell.
Vesicles. ANSWER - A small, membrane-bound sac in the cytoplasm that transports,
stores or digests substances.
Vacuole. ANSWER - A membrane-bound, fluid-filled space within a cell; used for storage.
Lysosome. ANSWER - An organelle within the cytoplasm containing digestive enzymes.
Ribosome. ANSWER - A small structure in all cells that builds amino acids into complex
proteins, this organelle is not bound by a membrane.
Endoplasmic Reticulum (ER). ANSWER - An organelle in eukaryotic cells consisting of an
interconnecting system of thin membrane sheets dividing the cytoplasm into compartments
and channels; lipid synthesis occurs here.
, Golgi Apparatus. ANSWER - A collection of membranes that package and store substances
into vesicles in preparation for their release from the cell.
Cytoskeleton. ANSWER - A system of microtubules and microfilaments that supports and
gives shape to the cell
Cell Wall. ANSWER - Gives support and protection to cell; made of cellulose in plants.
Chloroplasts. ANSWER - A membrane-bound organelle found in the cytoplasm of plants
and algae containing the green pigment, chlorophyll; its main function is photosynthesis
and storage of carbohydrates.
Nuclear Envelope. ANSWER - The membrane surrounding the nucleus.
Central Vacuole. ANSWER - Plant cells have large one to store water.
Cytoplasm. ANSWER - All the cytosolic fluid, dissolved materials and organelles between
the plasma membrane and nuclear membrane.
Nucleolus. ANSWER - The centre of the nucleus
Cell. ANSWER - The basic structural unit of all life forms on Earth.
Centriole. ANSWER - A structure in animal cells that produces an animal's microtubules
and are involved in spindle formation during cell division, usually located near the nucleus.
Deoxyribonucleic Acid (DNA). ANSWER - A molecule that is the universal basis of genetic
material. Made of nucleotide bases (A T G C), it contains instructions for the production of
proteins by the cell.
Eukaryote. ANSWER - A complex type of cell with a nucleus and membrane-bound
organelles.
