Plant Cell Labeling Quiz

Study Notes

Plant Cell Components

Chloroplasts: Organelles responsible for photosynthesis, converting light energy into chemical energy (glucose). Contains chlorophyll giving plants their green color.
Cell Membrane: Semi-permeable barrier surrounding the cell; regulates the entry and exit of substances, maintaining homeostasis.
Cell Wall: Rigid outer layer found in plant cells; provides structural support, protection, and maintains cell shape, primarily composed of cellulose.
Mitochondria: Known as the powerhouse of the cell; produces ATP (energy) through cellular respiration, essential for various cellular processes.
Vesicle: Small, membrane-bound sacs that transport materials within the cell, involved in processes such as secretion and metabolism.
Golgi Body: Organelle that modifies, sorts, and packages proteins and lipids for secretion or use within the cell; plays a crucial role in processing cellular products.
Cytoplasm: Jelly-like fluid inside the cell that contains organelles; facilitates movement of materials around the cell and is the site for many metabolic reactions.
Central Vacuole: Large storage organelle in plant cells, responsible for maintaining turgor pressure, storing nutrients, and waste products.
Smooth Endoplasmic Reticulum (Smooth E.R.): Network of membranes involved in the synthesis of lipids, metabolism of carbohydrates, and detoxification of drugs and poisons.
Rough Endoplasmic Reticulum (Rough E.R.): Studded with ribosomes, it synthesizes proteins for secretion or for use in membranes; plays a central role in the cell's protein production.
Nucleus: Control center of the cell that houses genetic material (DNA); directs cellular activities and regulates gene expression.
DNA: Deoxyribonucleic acid, the hereditary material in cells; contains the instructions for development, functioning, growth, and reproduction of organisms.
Nucleolus: Structure within the nucleus where ribosomal RNA (rRNA) is produced and ribosome subunits are assembled; essential for protein synthesis.
Nuclear Membrane: Double-layered membrane that encloses the nucleus, protecting genetic material and regulating the flow of substances in and out of the nucleus.
