Answer:

Filling the Blanks (Cell Organelles Worksheet)

1. Organelle - means “Little organ”

(Explanation: Organelle is a diminutive term, meaning a small "organ" of the cell, analogous to organs in a body.)

2. Cytoskeleton

• Plant (P)/Animal (A)/Both (B): B
• Function: Network of proteins that give shape & strength to cell (like the human skeleton)

(Explanation: The cytoskeleton provides structural support and shape to the cell, similar to how the skeleton supports the human body.)

3. Cytoplasm

• Plant (P)/Animal (A)/Both (B): B
• Function: Fills space between the nucleus & cell membrane. - consists mostly of cytosol (liquid)

(Explanation: Cytoplasm is the gel - like substance (cytosol) plus organelles, filling the cell’s interior.)

4. Nucleus

• Plant (P)/Animal (A)/Both (B): B
• Function: Control center of the cell - contains genetic info (DNA) - membrane has pores to allow some molecule to pass in and out (selectively permeable)

(Explanation: The nucleus controls cell activities by housing DNA, which directs cellular processes.)

5. Nucleolus

• Plant (P)/Animal (A)/Both (B): B
• Function: Found in the nucleus. Ribosomes are made here.

(Explanation: The nucleolus is a structure within the nucleus responsible for ribosome synthesis.)

6. Endoplasmic Reticulum (ER)

• Plant (P)/Animal (A)/Both (B): B
• Function: (ER) = network of interconnected membranes (like a conveyer belt or a series of canals used for transport)
• Rough ER - covered in ribosomes (protein factories)
• Smooth ER - no ribosomes make lipids & breaks down toxins

(Explanation: ER transports materials; rough ER makes proteins (via ribosomes), smooth ER synthesizes lipids and detoxifies.)

7. Ribosome

• Plant (P)/Animal (A)/Both (B): B
• Function: Tiny organelle that produce proteins. - found on Rough ER or in cytoplasm

(Explanation: Ribosomes are the site of protein synthesis in the cell.)

8. Golgi Apparatus

• Plant (P)/Animal (A)/Both (B): B
• Function: Modify, sort, and prepare proteins for export out of the cell. - proteins from ER move to Golgi for export.

(Explanation: The Golgi apparatus processes, sorts, and packages proteins for transport within or outside the cell.)

9. Mitochondria

• Plant (P)/Animal (A)/Both (B): B
• Function: Supply energy. “Power House” “Mighty - Chondria”! - inner folds convert molecules from food to usable energy thru the process of Cellular Respiration (ATP!)

(Explanation: Mitochondria generate ATP (energy) via cellular respiration, acting as the cell’s “powerhouse.”)

10. Vesicle

• Plant (P)/Animal (A)/Both (B): B
• Function: Small membrane bound sacs that transport materials throughout cell - EX. Vesicles take Proteins from ER to Golgi and then export Proteins out of the Cell.

(Explanation: Vesicles are transport “bubbles” for moving materials within the cell.)

11. Vacuole

• Plant (P)/Animal (A)/Both (B): P (larger), A (smaller), B (present)
• Function: fluid filled sacs (water, food molecules, enzymes, etc) - Much larger in plants than animals

(Explanation: Vacuoles store substances; plant vacuoles are large for water/storage, animal vacuoles are smaller.)

12. Lysosome

• Plant (P)/Animal (A)/Both (B): A (more common), B (some plants)
• Function: Contain enzymes to break down foreign material or damaged & worn out cell parts. (Lysol...cleans and disinfects)

(Explanation: Lysosomes use digestive enzymes to break down waste or invaders, like a cellular “cleanup crew.”)

13. Cell Membrane

• Plant (P)/Animal (A)/Both (B): B
• Function: Protects cell - Selectively Permeable: Allows some things in but not others (gate keeper)

(Explanation: The cell membrane regulates what enters/leaves the cell, acting as a “gatekeeper.”)

14. Cell Wall

• Plant (P)/Animal (A)/Both (B): P (plants), F (fungi), B (bacteria) - A: No
• Function: Plants, fungi & bacteria - rigid layer that gives protection, support & shape

(Explanation: The cell wall provides structural support and protection (e.g., in plants, it maintains shape).)

15. Chloroplast

• Plant (P)/Animal (A)/Both (B): P
• Function: Carry out photosynthesis turning solar energy into chemical energy (Glucose - sugar)

(Explanation: Chloroplasts use sunlight to make glucose via photosynthesis, unique to photosynthetic organisms like plants.)
