a.
To sketch: The plasmodesmata between adjacent plant cells.
Introduction: Plants and animals are multi-cellular organisms. Plant cells have cell wall that differentiates them from animal cells. The cell wall protects the plant cell and maintains its shape. It also holds against the force of the gravity.
b.
To list: The functions of the extracellular matrix of animal cells.
Introduction: A cell is the smallest structural, functional, and biological unit of all living organisms. It contains different organelles to carry out different functions. Some cells are specific to their functions. Unicellular organisms are raised from a single cell but multi-cellular organisms are raised from many cells. Many animal cells are also surrounded by the extracellular matrix (ECM).

Transcription and Translation Practice: (Video 10-1 and 10-2) A. Below is the sense strand of a DNA gene. Using the sense strand, create the antisense DNA strand and label the 5' and 3' ends. B. Use the antisense strand that you create in part A as a template to create the mRNA transcript of the gene and label the 5' and 3' ends. C. Translate the mRNA you produced in part B into the polypeptide sequence making sure to follow all the rules of translation. 5'-AGCATGACTAATAGTTGTTGAGCTGTC-3' (sense strand) 4arrow_forwardWhat is the structure and function of Eukaryotic cells, including their organelles?
