Cell Wall and Membrane, Bioflix activity: tour of a plant cell — cell structures
The plant cell wall is composed of cellulose, hemicellulose, and pectin, providing rigidity and protection. The cell membrane, composed of a phospholipid bilayer, regulates the entry and exit of molecules, maintaining cellular homeostasis.
Nucleus and Ribosomes
The nucleus is the control center of the cell, housing the genetic material (DNA). Ribosomes, composed of RNA and protein, are responsible for protein synthesis.
Chloroplasts and Mitochondria
Chloroplasts contain chlorophyll, which absorbs sunlight and converts it into energy through photosynthesis. Mitochondria generate energy through cellular respiration, using oxygen to break down glucose.
Vacuoles and Endoplasmic Reticulum
Vacuoles are membrane-bound compartments that store water, nutrients, and waste products. The endoplasmic reticulum is a network of membranes that synthesizes and transports proteins and lipids.
Golgi Apparatus and Lysosomes
The Golgi apparatus modifies and packages proteins and lipids for secretion. Lysosomes are organelles that contain digestive enzymes to break down cellular waste.
Cytoskeleton and Cell Division
The cytoskeleton, composed of microtubules, microfilaments, and intermediate filaments, provides structural support and facilitates cell movement. Cell division is the process by which cells divide to create new cells, ensuring growth and tissue repair.
