an Animal Cell: Structures and Functions (BioFlix tutorial) To understand how cells function as the fundamental unit of life, you must first become familiar with the individual roles of the cellular structures and organelles. Drag the labels on the left onto the diagram of the animal cell to correctly identify the function performed by each cellular structure.

The Cell Exercise A: Eukaryotic Organelles In the cell diagram below: 1. Label the following events of protein synthesis and recycling: 1) Transcription 2) mRNA leaves through nuclear pore 3) Translation at ribosome in rough ER 4) Transport vesicle shuttles unmodified protein 5) Protein is modified in Golgi Apparatus 6) Lysosome digests worn out protein. 2. At the mitochondrion. a. Draw an arrow to the mitochondrion with "glucose" attached b. Draw an arrow out of the mitochondrion with "38 ATP" attached 3. Label the vacuole. 4. Label the smooth ER. Lab: Investigating Plant Cells In this exercise, you will identify several visible characteristics of plant cells. Individual plant cells differ in three main ways from animal cells. (1) Plant cells have photosynthetic organelles, chloroplasts, that appear green under a compound microscope. (2) While animal cells have vacuoles, a plant cell's vacuoles are very large in comparison. The main function of plant vacuoles is to store water between precipitation events. (3) Plant cells have thick primary cell walls made of the polysaccharide, cellulose. Plant cells involved in structural support also have a secondary cell wall made of a very dense polysaccharide

Complete the table by dragging each structure name or description into the appropriate place. Stacked, flat, single-membrane sacs Synthesizes lipids; detoxifies drugs and poisons Golgi apparatus Creates vesicles to enclose materials to be secreted; produces lysosomes Ribosome Location of protein synthesis Rough endoplasmic reticulum Smooth endoplasmic reticulum Organelle | Function(s) | Structure | Plant or Animal? ---|---|---|--- | | | Animal and plant | | Two subunits of RNA and protein synthesized in the nucleolus of eukaryotic cells | Animal and plant | | A single-membrane network | Animal and plant | Produces proteins destined for secretion from the cell | A single-membrane network covered with ribosomes | Animal and plant

Part 1. This activity will help you identify functions of cellular structures. • Label each listed function with the corresponding cellular structure. • Use full names, not abbreviations. (Acceptable: smooth endoplasmic reticulum; unacceptable: smooth ER). • Many cellular structures serve multiple functions and therefore may be listed more than once. Cellular Structure | Function --- | --- | adhere neighboring animal cells together but do not allow passage of molecules between cells | allows passage of molecules between the nucleus and cytoplasm | captures light energy to link carbon molecules to synthesize carbohydrates | enclose "cargo" to be moved between other organelles of the endomembrane system | converts chemical energy from macromolecules to ATP | extracellular structure that provides support for the cell | facilitate autophagy | intracellular structure provides support and structure for the cell | maintains shape of the nucleus | modifies proteins | moves cells | moves vesicles within cells | secretes glycoproteins | stores calcium | stores genetic information | synthesizes lipids | synthesizes proteins | tunnels that allow passage of water and small molecules between plant cells
