chloroplast


  1. (in green plant cells) a plastid that contains chlorophyll and in which photosynthesis takes place.


100

carbon cycle

the process that moves carbon between plants, animals, and microbes; minerals in the earth; and the atmosphere.

100

decrease

make or become smaller or fewer in size, amount, intensity, or degree.

100

excretory system

The excretory system in humans consists mainly of the kidneys and bladder.

100

photosynthesis take place

in chloroplasts,

200

Organelles


any of a number of organized or specialized structures within a living cell.

200

structural adaptation

help organisms obtain the food they need to survive the climate and environmental conditions or to move with ease, for instance, to evade predators.

200


chlorophyll

detoxes the body, strengthens the immune system, and boosts energy,

200

circulatory system


  1. the system that circulates blood and lymph through the body, consisting of the heart, blood vessels, blood, lymph, and the lymphatic vessels and glands.


200

glucose

Glucose is the main type of sugar in the blood and is the major source of energy for the body's cells.

300

nucleus


  1. the central part of an atom.


300

what vacuole use for

sequester waste products

300

a fancy way to say sugar

glucose

300

muscular system

muscular system

300

single-celled

Made up of only one cell. Bacteria are single-celled organisms.

400

mitochondrion


  1. an organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur. It has a double membrane, the inner layer being folded inward to form layers (cristae).


400

what ribosomes use for

 making proteins.

400

photosynthesis

the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.

400

nervous system

 includes the brain, spinal cord, and a complex network of nerves.

400

multicellular


  1. (of an organism or part) having or consisting of many cells.
500

cell membrane


  1. the semipermeable membrane surrounding the cytoplasm of a cell.


500

what cell wall use for

 provides the cell with both structural support and protection, and also acts as a filtering mechanism.

500

water cycle

Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow.

500

increase

become or make greater in size, amount, intensity, or degree.

500

green house effect

 the process through which heat is trapped near Earth's surface by substances known as 'greenhouse gases.
