Bacteria & Survival
A bacterial cell absorbs free, "naked" DNA directly from its liquid environment without needing a viral vector or living donor cell?
Transformation
This category of animal viruses engages in chronic, long-term replication over decades without immediately killing or lysing the host cell, as seen in HIV/AIDS and Hepatitis?
Persistent virus
Microscopic aquatic protists—such as diatoms, dinoflagellates, and algae—produce a massive portion of Earth's oxygen through this metabolic process?
Photosynthesis
Early land plants evolved this waxy surface coating on leaves and stems to seal in moisture and prevent drying out?
Waxy cuticle
Fungi obtain nutrients not by ingestion, but by releasing digestive enzymes externally into surrounding organic matter and absorbing the broken-down molecules?
Absorptive heterotrophy
Certain Gram-positive bacteria produce this tough, dormant structure to survive extreme heat, radiation, and desiccation for centuries?
Endospore
A patient who had chickenpox as a child carries the Varicella zoster virus hidden inside sensory nerve cells for 30 years before it reactivates as shingles, placing it in this viral classification?
latent virus?
According to the Endosymbiosis Theory, chloroplasts inside plant and algae cells originally evolved when an ancient host cell engulfed this type of photosynthetic bacteria?
Cyanobacteria
Non-vascular plants like mosses lack true roots and vascular tissue, anchoring themselves to damp soil using these simple thread-like structures?
Rhizoids
Most land plants depend on this vital underground mutualistic relationship where soil fungi assist plant roots with water and mineral absorption?
Mycorrhizae
A living donor bacterium transfers a multi-drug resistance plasmid directly to a recipient cell through a physical cytoplasmic bridge called a pilus in this process?
Conjugation
During the lysogenic cycle of a temperate bacteriophage, the double-stranded viral DNA integrates directly into the host bacterial chromosome to form this structure?
Prophage
An underwater forest off the Pacific coast consists of towering, tree-like structures anchored to the sea floor . Although these giant kelp organisms resemble true land plants, marine biologists classify them under this diverse eukaryotic group?
Protist
This specialized vascular tissue consists of dead, reinforced cells that transport water and dissolved minerals upward from roots to shoots.
Xylem
A pioneer composite organism found blanketing bare volcanic rock consists of a fungus living symbiotically with photosynthetic algae?
Lichen
Engineers use oil-degrading bacteria to clean up toxic marine oil spills in this eco-friendly process?
Bioremediation
Human Papillomavirus (HPV) induces uncontrolled host cell division and tumor formation in epithelial tissues, categorizing it as this type of animal virus?
Oncovirus
What group do protist belong to? Archeae? Plants? Animals? Bacteria?
They are there own group
Unlike mosses and ferns whose swimming sperm require standing water, seed plants reproduce on dry land because sperm cells travel inside these wind- or animal-dispersed structures?
Pollen
Following successful fertilization in flowering plants, the floral ovule develops into a seed, while the surrounding ovary matures into this structure.
Fruit
Bacterial DNA is mistakenly packaged inside a viral vector and transferred to a new bacterial cell during this mechanism of gene exchange?
transduction
These structured microbial communities anchor to surfaces like medical catheters or human teeth, shielding themselves inside a self-secreted slimy matrix.
Biofilm
Under a microscope, an animal-like single-celled eukaryote extends its cell membrane to surround an organic particle, enclosing it inside an internal food vacuole for digestion. Which cellular feeding process is being observed?
Phagocytosis
Early land plants faced intense structural challenges from gravity as they evolved to grow taller to compete for sunlight. Which rigid polymer incorporated into vascular cell walls provided the structural support needed for plants to stand upright on land?
Lignin
During angiosperm double fertilization, one sperm fertilizes the egg cell to form a zygote, while the second sperm forms this nutrient-rich storage tissue?
Endosperm
