Study Notes

Animal and Plant Cell Structure

Cell Membrane: Provides structure and support; regulates what enters and exits the cell.
Cytoplasm: Gel-like substance filling the cell, supporting organelles and facilitating chemical reactions.
Endoplasmic Reticulum: Essential for the transport of materials; can be rough (with ribosomes) or smooth (without ribosomes).
Golgi Apparatus: Modifies, sorts, and packages proteins and lipids for transport.
Mitochondrion: Known as the "Power House" of the cell; responsible for cellular respiration and energy production.
Nucleus: Acts as the control center; stores DNA and regulates cellular activities, including reproduction.
Vacuole: Functions as a storage unit for food, water, waste, and other substances within the cell.
Cell Wall: Rigid outer layer found in plant cells; provides additional support and protection.

Differences Between Cell Types

Plant Cell: Contains a cell wall, chloroplasts for photosynthesis, and a large central vacuole.
Animal Cell: Lacks a cell wall and chloroplasts, features a smaller vacuole.

Unique Organelles and Structures

Chloroplast: Site of photosynthesis in plant cells, converting light energy to chemical energy.
Lysosomes: Contain enzymes for digesting cellular waste and foreign materials.
Nucleolus: Dense structure within the nucleus responsible for ribosomal RNA synthesis.
Nuclear Membrane: Double-layered membrane enclosing the nucleus, continuous with the endoplasmic reticulum.

Additional Cell Components

Ribosomes: Small particles composed of RNA and proteins; essential for protein synthesis by translating messenger RNA.
Organelles: Specialized structures within cells, each performing specific functions vital for cell survival and efficiency.

Summary of Cell Fundamentals

Cell: The basic unit of life; all living organisms are made of cells.
Mitochondria and Chloroplasts are crucial for energy production in their respective cell types.
Vacuoles serve as storage compartments, playing vital roles in maintaining cell homeostasis.
