What is the function of ribosomes? -correct-answer-protein synthesis by
translating mRNA
What is the cytoskeleton? -correct-answer-a microscopic network of protein
filaments and tubules in the cytoplasm of many living cells, giving them shape and
coherence.
What is exocytosis? -correct-answer-a process by which the contents of a cell
vacuole are released to the exterior through fusion of the vacuole membrane with
the cell membrane.
What is endocytosis? -correct-answer-the taking in of matter by a living cell by
invagination of its membrane to form a vacuole
,2|Page
What is the function of a cell membrane? -correct-answer-The cell membrane
regulates what enters and leaves the cell and also protects and supports the cell
Cell membrane diagram -correct-answer-
Describe the process of mitosis -correct-answer-- Start with: Diploid, 2N
- Interphase: DNA replication = Dipoid, 4N
- Prophase: Condensation of chromatin,
appearance of sister chromatids
- Metaphase: Sister chromatids align
- Anaphase: Sister chromatids separate,
centromeres divide
- Telophase and Cytokinesis: Two identical,
diploid, daughter cells: Diploid, 2N
Describe the process of meiosis -correct-answer-When a cell divides to form
gametes:
1. Copies of the genetic information are made
2. The cell divides twice to form four gametes, each with a single set of
chromosomes
3. All gametes are genetically different from each other
, 3|Page
Gametes join at fertilisation to restore the normal number of chromosomes. The
new cell divides by mitosis. The number of cells increases. As the embryo
develops, cells differentiate.
When does crossing over occur? -correct-answer-prophase I of meiosis
When does recombination occur in meiosis? -correct-answer-during prophase I,
when homologous chromosomes line up in pairs and swap segments of DNA.
What is the structure of prokaryotic cells? -correct-answer-
Example of prokaryotic cell -correct-answer-E. coli
Example of eukaryotic cell -correct-answer-plant and animal cells
What is the structure of eukaryotic cells? -correct-answer-
