EXERCISE 3. EUKARYOTIC CELLS
The delivery of this exercise is mandatory and it becomes a requirement so you have the right to deliver your Evidence 1
Description Objective:
To analyze the essential differences of eukaryotic cells.
Description:
The student will investigate examples of eukaryotic, animal and plant cell types.
Requirements:
Information about the structure of the cell and the classification of its parts.
Instructions for the student:
- Look for 15 representative images of the eukaryotic cell of animal and vegetal origin; also, look for the illustrations of each one.
- Locate your images in a comparative chart and point out the function of each part of the cell.
- In the comparative chart, place the image and indicate the part of each cell using lines. Check the following example:
Cell type Image Example Function of each part Main function
Eukaryote: animal
Neuron Dendrites: are extensions of the cell body and they serve to increase the capability to contact other nerve cells. Nucleus: contains all cellular information and DNA. It does not reproduce. Axon: its function is to carry organelles, proteins, and synaptic vesicles. Axon terminal: In this part the neurotransmitters are released to send information to the contiguous cell. Myelin sheath: is the lipidic substance. Cell body (soma): it contains lysosomes, nucleus,
Specialized in receiving stimuli.

Main Function
Eukaryote: animal
Sperm
Head: Contains genetic info and helps penetrate the egg. Acrosome: Surrounds the head and contains enzymes to help penetrate the egg Midpiece: Contains mitochondria for energy production. Nucleus: Contains genetic material for the fertilization. Centrioles: Assists in the cell-
Reproductive cell that serves vitally in the creation of life.
division process of mitosis and meiosis
Mitochondria: Serves for energy production to the cell.
Flagellum: Useful to get through the female reproductive system.
Tail: Modified flagella that helps movement.
Tail sheath: Part that helps the sperm swim or move.
Eukaryote: animal
Fat Cell Adipocyte
Mitochondria: In charge of producing energy.
Membrane: Protects the insides of the cell from external damage.
Cytoplasm: A thick solution used to fill the cell up.
Fat reservoir: Energy matter.
Nucleus: It contains the majority of the cell's genetic material organized in DNA molecules and proteins to form chromosomes.
Golgi apparatus: Takes care of modifying, sorting
Body’s main depot for energy storage and mobilization.
and packaging of proteins for secretion. It also helps to transport lipids around the cell, and create lysosomes.
Eukaryote: animal
Ovum Cytoplasm: Called ooplasm It contains a tiny amount of yolk making it alecithal.
Follicle Cells: Protects the inner layers.
Corona Radiata: Protects the inner layers and helps prevent polyspermy.
Plasma Membrane: Thin layer that protects the inner layers helping prevent polyspermy when
As a reproductive cell, it needs to find a sperm in order to develop as a new living being.
Eukaryote: animal
Platelet Mitochondria: Helps with the producing of energy of the cell.
Dense granule: Specialized secretory organelle that contributes to blood coagulation.
Alpha granule: Include insulin-like growth factor 1, platelet-derived growth factors, TGFβ, platelet factor 4 and many more that help the platelet in its growth.
Coat: Exterior layer that protects the platelet form exterior damage.
Glycogen: Used to get glucose
Reacts to bleeding from a blood vessel injury by making a blood clot so there is no blood loss.
from glycolysis, and anaerobic glycolysis, the two more important metabolic pathways in platelets.
Tubule system: Helps and provides the cytoplasm with elements like calcium and connects to the surface platelet membrane to aid thromboxane A release.
Eukaryote: animal
Neuron Dendrite: It is an input region that receives information from other cells.
Nucleus: Produces RNA that supports important cell
Receives, processes and transmits and chemical signals chemically and electrically.
Node of Ranvier: Have a high content of ion channels that allows it to participate in the exchange of ions needed to regenerate the action potential.
Eukaryote: animal
Smooth muscle cell
Nucleus: Contains genetic material.
Intermediate filament: Helps shrinking the cell when the muscle needs to move and support cell structure.
Caveolae: Small vesicular invagination in the membrane. Helps to perform transcytosis, potocytosis and
Found in walls of hollow organs and body parts protecting them of external damage.
signal transduction.
Dense bodies: Help connect intermediate filaments to other filaments.
Gap junctions: This electrically connect the cell to other cells. It helps to synchronize.
Eukaryote: Plant
Meristematic cell
Cell wall: Contains all the insides in place and protects it from external damage.
Nucleus: Contains all genetic data the cell needs.
Helps regrow any specific tissue of the plant at any point during its life.
metabolism.
Eukaryote: Plant
Collenchyma cell
Thickened corner: Packed with cellulose this corners help with other cells to grow shoots and leaves.
Vacuole: It’s a chamber covered with membrane, it holds various solutions and materials.
Protoplasm: Organic and inorganic content vital for the cell’s life.
Cell wall: Protects the cell from external damage and keeps it whole.
Helps in the growth of new tissue proving mechanical and structural support.
Eukaryote: Plant
Phloem Companion cells: Packed with cytoplasm, ribosomes and mitochondria they undertake metabolic reactions.
Sieve-tube element: Narrow cells that due to the lack of common organelles like ribosomes they help to structure the phloem and translocate materials.
Sieve plate: Modified plasmodesmata that facilitates the exchange of material between cells.
Nucleus:
Transport sugars to the plant organs by using turgor pressure and energy in the form of ATP.
Eukaryote: Plant
Xylem Tracheids: Conduct water, minerals and xylem sap. Provide structural support.
Vessel element: Transports with the tracheids water and minerals.
Perforation plate: Allows the passage of water and dissolved substances.
Pits: Contains the secondary and the primary cell wall.
The secondary is thin allowing water to flow.
Transports water and nutrients from the roots to the leaves.
Eukaryote: Plant
Sclerenchyma cell
Primary cell wall: Thick wall that holds together the insides of the cell. It is waterproof and strong.
Thick secondary cell wall: Interior wall that hugs and protects the interior of the cell. It is relatively thick and strong.
Supports tissue of various types of hard woody cells.
