The "brain" of the cell that controls the cell function. It contains DNA in chromosomes.
What is the nucleus?
100
This human body system supports structure in the body.
What is the skeletal system?
100
A way in which organisms reproduce. There are sexual and asexual variations of it.
What is reproduction?
100
This kingdom includes diverse eukaryotes including algae, protozoans, and lower fungus.
What are protists?
100
The single building block of all organisms.
What is a cell?
200
This type of cell has a bigger vacuole and has a cell wall unlike its counterpart.
What is a plant cell?
200
This important organ pumps blood throughout the body and is greatly affected by lifestyle choices (Good ones increase longevity of this organ, bad ones decrease). It is arguably one of the most important organs in the body.
What is the heart?
200
An organelle found in most cells where respiration and energy production occur in the cell.
What is mitochondria?
200
These eukaryotic organisms have chlorophyll which causes their greenish tint. They are apparent in water and can come in multicellular clumps called kelp.
What is an alga? (or what are algae)
200
This organ is part of the excretory system. It excretes bile.
What is the liver?
300
Where most of the digestion of the cell is done.
What is a lysosome?
300
This organ is where most of the water and waste is taken out of food and processed, and where it transports the waste to other organs to be excreted. It is actually smaller in length than its counterpart.
What is the large intestine?
300
A category of which an organism has many cells.
What is multicellular?
300
These protists help amoeba move and eat.
What are pseudopods? (Pseudopodia also acceptable)
300
A storage place for water and waste in a cell. Plant cells have larger variations of this organelle.
What is a vacuole?
400
A small body near the nucleus. It makes microtubules. The dense section of this body is called the centriole.
What is a centrosome?
400
These are the cells in blood that attack bacteria. They are also known as white blood cells.
What are leukocytes? (or T-Cells) (do not accept white blood cells)
400
The material that organisms are made of, compiled of many cells with a common job.
What is tissue?
400
Protists can sometimes be these. Some examples include plasmodium, which causes malaria in humans, and phytophthera infestans, which causes late blight in potatoes.
What is a pathogen?
400
An organ system that allows the body to move, maintains posture and circulates blood. There are smooth, skeletal, and cardiac variations of the organs that make up this system.
What is the muscular system?
500
A network of membranous tubules in the cytoplasm of a cell. It usually has ribosomes attached and is part of protein synthesis. There are rough and smooth variations of it.
What is endoplasmic reticulum?
500
This organ carries oxygenated blood throughout the body, except for the pulmonary variation of it.
What is an artery?
500
A green, single-celled organism that sometimes form green scum on water.
What is a euglena?
500
Types of protists that use light energy and converts it into glucose.
What are photosynthetic autotrophs?
500
This is a kind of green algae. They contain chlorophyll and live in large colonies that consist up to 50 thousand, mainly in freshwater habitats.
