Classification & Evidence
This type of evidence compares DNA or RNA sequences to determine evolutionary relationships.
What is molecular evidence?
These organisms are single-celled and lack membrane-bound organelles.
What are bacteria?
All viruses contain genetic material surrounded by this structure.
What is a protein capsid?
This plant tissue transports water and minerals upward from the roots.
What is xylem?
This type of reproduction requires only one parent and produces clones.
What is asexual reproduction?
These two groups were once classified together but later separated due to genetic differences.
What are bacteria and archaea?
This fungal structure allows fungi to reproduce and spread in the environment.
What are spores?
This explains why antibiotics do not work on viral infections.
What is that viruses lack cellular structures antibiotics target?
This tissue transports sugars produced during photosynthesis.
What is phloem?
This plant hormone controls growth toward light and gravity.
What is auxin?
This group of organisms is eukaryotic but not considered a true biological kingdom due to extreme diversity.
What are protists?
This protist structure helps organisms like paramecia move through water.
What are cilia (or flagella)?
Viruses must use this to replicate new viral particles.
What is a host cell?
This waxy layer helps plants reduce water loss on land.
What is the cuticle?
This process transfers pollen from the anther to the stigma.
What is pollination?
This type of organism is not considered living because it cannot reproduce or maintain homeostasis on its own.
What are viruses?
A scientist removes this organism from a forest ecosystem and later observes that plant roots absorb fewer nutrients and grow more slowly.
What is a fungus?
This is one reason viruses are not considered living organisms.
What is inability to maintain homeostasis or metabolism?
This force explains how water moves upward through xylem against gravity.
What is cohesion and transpiration pull?
This plant response occurs when roots grow toward areas with higher moisture.
What is hydrotropism?
This advancement in science changed classification from visible traits to evolutionary relationships.
What is DNA/RNA sequencing technology?
This ecological role describes fungi breaking down dead organic matter.
What are decomposers?
This term describes viruses that infect only specific types of host cells.
What is host specificity?
This plant substance strengthens tissues and allows plants to grow tall.
What is lignin?
This type of plant response causes tendrils to coil around a support.
What is thigmotropism?
