Transcribed Image Text:**Plant Cell Diagram Description**
This diagram provides a detailed depiction of a plant cell structure, showcasing various organelles and components integral to its function:
1. **Nucleus**: The central purple sphere representing the nucleus contains the cell's genetic material and is the control center for cell growth and reproduction.
2. **Rough Endoplasmic Reticulum (ER)**: Illustrated in blue with small dots, these are ribosomes responsible for protein synthesis and transport within the cell.
3. **Smooth Endoplasmic Reticulum (ER)**: The blue structure without ribosomes, involved in lipid synthesis and detoxification processes.
4. **Golgi Apparatus**: Shown in pink, this series of stacked membranes modifies, sorts, and packages proteins and lipids for storage or transport out of the cell.
5. **Central Vacuole**: A large, light green, membrane-bound space that stores water, nutrients, and waste products, contributing to cell rigidity.
6. **Chloroplasts**: The green structures containing stacks of membranes where photosynthesis occurs, converting solar energy into chemical energy.
7. **Mitochondria**: The orange organelles known as the powerhouse of the cell, where energy (ATP) is produced through cellular respiration.
8. **Cell Wall**: The thick, outermost layer in beige provides structural support and protection to the plant cell.
9. **Plasmodesmata**: Represented by small blue channels through the cell wall, allowing communication and transport between adjacent plant cells.
This cross-sectional view illustrates the complex yet organized structure of plant cells, highlighting the specialized functions of each organelle.
Transcribed Image Text:**Figure 1. Animal Cell Diagram**
This diagram provides a detailed illustration of an animal cell, showcasing its various organelles and structures. Each component is labeled with a line pointing to its corresponding part in the cell:
1. **Cell Membrane** - The outer boundary that protects the cell and regulates what enters and exits.
2. **Nucleus** - The cell's control center, containing genetic material (DNA).
3. **Nucleolus** - Located within the nucleus, responsible for ribosomal RNA synthesis.
4. **Ribosomes** - Small structures involved in protein synthesis, found in the cytoplasm or on the rough endoplasmic reticulum.
5. **Rough Endoplasmic Reticulum (Rough ER)** - Studded with ribosomes; involved in the synthesis of proteins and membrane production.
6. **Smooth Endoplasmic Reticulum (Smooth ER)** - Lacks ribosomes; involved in lipid synthesis and detoxification processes.
7. **Golgi Apparatus** - Stacks of membranes involved in modifying, sorting, and packaging proteins and lipids for transport.
8. **Mitochondria** - The powerhouse of the cell, producing energy in the form of ATP through cellular respiration.
9. **Lysosomes** - Contain digestive enzymes to break down waste materials and cellular debris.
10. **Centrioles** - Involved in cell division, helping to organize the mitotic spindle.
11. **Cytoplasm** - The jelly-like substance filling the cell, where various organelles are suspended.
12. **Cytoskeleton** - Provides structural support to the cell and its organelles.
This diagram serves as a useful educational resource for understanding the structure and function of an animal cell.
Expert Solution
Step 1
The cell is the basic unit of life. It consists of the outer cell membrane, inner cytosplsm, cell organelles, nucleus, and genetic material. Each living organisms is made up of cell. Organisms can be made up of either one cell called unicellular organisms or many cells called muticellular organisms.
