Accepted Answer

### Question 1: Functions of Organelles
#### Golgi Apparatus:
# Brief Explanations:
The Golgi Apparatus modifies, sorts, and packages proteins and lipids received from the endoplasmic reticulum. It also dispatches these molecules to their final destinations, either within the cell or for secretion outside the cell.
# Answer:
Modifies, sorts, packages proteins/lipids; dispatches to destinations.

#### Vacuole:
# Brief Explanations:
In plant cells, the large central vacuole stores water, nutrients, and waste products. It also helps maintain turgor pressure, which provides structural support. In animal cells, smaller vacuoles are involved in storage, transport, and sometimes waste management.
# Answer:
Plant: stores water/nutrients/waste, maintains turgor. Animal: storage, transport, waste management.

#### Lysosome:
# Brief Explanations:
Lysosomes contain digestive enzymes. They break down worn - out cell parts, engulfed viruses or bacteria, and recycle the resulting molecules for the cell's use. They act as the "digestive system" of the cell.
# Answer:
Contains digestive enzymes; breaks down cell waste, pathogens; recycles molecules.

#### Cytoskeleton:
# Brief Explanations:
The cytoskeleton provides structural support to the cell, helping it maintain its shape. It also facilitates cell movement (like in amoeboid movement), and is involved in the movement of organelles within the cell and in cell division (aiding in chromosome separation).
# Answer:
Provides cell structure/shape; enables cell/organelle movement; aids cell division.

### Question 2: Difference between Vacuoles in Animal and Plant Cells
# Brief Explanations:
- **Size and Number**: Plant cells usually have one large central vacuole that can occupy a significant portion (up to 90%) of the cell's volume. Animal cells have multiple smaller vacuoles.
- **Function Emphasis**: The plant vacuole is mainly for water storage (to maintain turgor pressure), storage of nutrients and waste. Animal vacuoles are more involved in temporary storage, transport, and sometimes waste disposal, and they do not play a major role in maintaining cell structure (as plant vacuoles do with turgor).
# Answer:
Plant vacuoles: 1 large, stores water (turgor), nutrients/waste. Animal vacuoles: multiple small, for storage/transport/waste; no turgor role.
