“Sihay – Ang Silid ng Buhay”
(In celebration of Buwan ng Wika & Nat’l Heroes Day, we are using the word ‘sihay’ - the Filipino term for cell)
I.
Unang bahagi. Gumuhit ng sihay ng tao at pangalanan ang mga bahagi nito.
II. Pangalawang bahagi. Gamit ang iyong iginuhit, gumawa ng listahan ng mga organulo na makikita sa sihay ng tao. Dapat ding ilakip ang mga taan o tungkulin ng bawat organulo. Organulo (Organelle) 1. Plasma Membrane
2. Nucleus 3. Ribosome
Taan/Tungkulin (Functions) Functions as the outer boundary of the cell; controls the entry and exit of substances; receptor proteins function in intercellular communication; marker molecules enable cells to recognize one another. Is the control center of the cell; DNA within the nucleus regulates protein (e.g., enzyme) synthesis and therefore the chemical reactions of the cell. Serves as site of protein synthesis.
4. Rough endoplasmic reticulum
Synthesizes proteins and transports them to Golgi Apparatus.
5. Smooth endoplasmic reticulum
Manufactures lipids and carbohydrates; detoxifies harmful chemicals; stores calcium.
6. Golgi apparatus
Modifies, packages, and distributes proteins and lipids for secretion or internal use.
7. Lysosome
Contains digestive enzymes.
8. Peroxisome
Serves as one site of lipid and amino acid degradation; breaks down hydrogen peroxide.
9. Proteasomes
Break down proteins in the cytoplasm.
10. Mitochondria
Are major sites of ATP synthesis when oxygen is available.
11. Centrioles
Serve as centers for microtubule formation; determine cell polarity during cell division; form the basal bodies of cilia and flagella.
12. Cilia
Move materials over the surface of cells.
13. Microvilli
Increase surface area of the plasma membrane for absorption and secretion; modified to form sensory receptors.
14. Cytoplasm
Acts as a buffer and protects the genetic material of the cell and also the cellular organelles from damage caused due to movement and collision with other cells.
15. Chromatin
Compresses the DNA into a compact unit that will be less voluminous and can fit within the nucleus.
16. Cytoskeleton
Helps cells maintain their shape and internal organization, and it also provides mechanical support that enables cells to carry out essential functions like division and movement. Mediates the vesicular transport of cargo: hormones or neurotransmitters - from an organelle to specific sites at the cell membrane, where it docks and fuses to release its content.
17. Secretory Vesicles
Anong organulo ang makikita sa loob ng isa pang organulo na mitochondria? Ano ang taan nito? Sagot: The inner membrane of the mitochondria folds over many times and creates layered structures called cristae. The fluid contained in the mitochondria is called the matrix. III. Ikatatlong bahagi. Ibat-ibang uri ng sihay. Sa bawat larawan, 1. alamin kung anong uri ito ng sihay; 2. lagyan ng pangalan ang mga bahagi nito; at 3. isulat kung saang tisyu o organo kung saan ito mahahanap. 1. Cardiac Muscle Cell
Intercalated disks Nucleus
2. Intercalated disc, Nucleus 3. Heart
Perivitelline space
Egg cytoplasm Corticol granule Egg plasma membrane
1. Egg Cell 2. Egg cytoplasm, cortical granule, egg plasma membrane, vitelline layer, perivitelline space 3. Ovaries
Vitelline layer Glial Cells
1. Nerve Cell 2. Neurons, Glial cells 3. Brain Tissue
Neurons
Platelets Erythrocytes
1. Red Blood Cell 2. Erythrocytes, Platelets 3. Blood
IV. Ika-apat na bahagi. Na diskobre ito taong 2018, anong organulo ito? Isulat ang taan o tungkulin nito
Sagot: The image above is the TIGER domain. A minor membrane less organelle in which messenger RNA encodes certain types of proteins to find the appropriate environment for growth. It is closely allied with the endoplasmic reticulum where proteins are made. According to Christine Mayr, one of the two cell biologists who discovered it, it is a sorting mechanism since it admits specific messenger RNAs according to certain rules and excludes. Then it shapes how the proteins made from those messenger RNAs will function.

Hindi ito multiple choice, identification, true or false, enumeration, o fill-in-the-blanks na sinasagutan, kundi essay na isinusulat araw-araw. Huhusgahan ito hindi base sa kung tama o mali ang sagot, kundi base sa kung may kabuluhan ang mga naisulat o wala. Allowed ang erasures.” ― Bob Ong, ABNKKBSNPLAKo?!
