This is the term used to summarize these chemical reactions in the cell.

Which is not a characteristic of living organisms?

True or False: Because energy does not cycle, ecosystems

could not stay in existence without solar energy and the ability of photosynthetic organisms to absorb it.

Movement in animals and humans, are dependent upon their?

This change in the frequency of traits in populations

and species is called?

It is the discipline of identifying and grouping organisms according to certain rules.

It is the study of the evolutionary relationships between organisms.

They live in aquatic environments that lack oxygen or are too salty, too hot, or too acidic for most other organisms.

Some can make their own food (photosynthesizers), while others must ingest their food.

An English scientist, who was the first to use the term “cell.”

He concluded that cells came from preexisting cells; "sperm fertilizing an egg".

All cells are surrounded by this consisting of a

phospholipid bilayer embedded with protein molecules.

This contain protein and RNA in 2 subunits and are used for protein synthesis.

This functions for processing, packaging and distribution of proteins and lipids.

Its function focused on cellular respiration.

Its function focused on photosynthesis.

It maintains the shape of the cell and allows its parts to move.

Human hair is strengthened by the presence of this?

The skin cells of a chameleon rely on this to move pigment granules around so that they can take on the color of their environment.

It is used to refer to the building up (synthesis) of molecules.

It is the common energy currency of cells

It is called a “high-energy” compound because of the energy stored in the chemical bonds of the phosphates.

It is an aerobic process that

requires oxygen (O2) and gives off carbon dioxide (CO2).

It converts solar energy into the chemical energy of a carbohydrate.

True or False: Photosynthetic organisms, including plants, algae, and cyanobacteria, are called heterotrophs.

The carotenoids give photosynthesizing cells a blue to violet color.

It is a fluid-filled space where carbon dioxide is enzymatically reduced to carbohydrate.

These are made up of thylakoids, membranous disks that

contain photosynthetic pigments such as chlorophylls.

Both plant and animal cells carry on cellular respiration.
